[0014] In an implementation, the first pattern may be set in at least two of the first, second, and third emission regions.

[0015] In one embodiment, a color filter disposed in an emission area where no first pattern is provided may include a central portion disposed in the emission area where no first pattern is provided, and an edge portion surrounding the central portion and having a height higher than the height of the central portion.

[0016] In one implementation, the first pattern may be formed as a light-transmitting pattern.

[0021] In one embodiment, the second pattern may be disposed below the first light-blocking layer and may overlap with the first light-blocking layer.

[0022] In one embodiment, the second pattern and the first light-blocking layer can be integrated into each other.

[0023] In one implementation, the second pattern may be set only in the non-emitting region of the second pixel, or may not be set in the emitting region of the second pixel.

[0026] In one embodiment, the central portions of the color filters that transmit light of the same color and are arranged on the light-emitting element of the first pixel and the light-emitting element of the second pixel may have the same thickness.

[0027] According to aspects of this disclosure, an electronic device including a display apparatus is provided. The display apparatus includes a display area, a light-emitting element layer, a color filter layer, a first light-blocking layer, a first pattern, and a second light-blocking layer.

[0029] Furthermore, according to the implementation, viewpoint shift can be improved by differentially and / or selectively setting at least one of the first pattern and the second pattern below the color filter of the first pixel and the second pixel.

[0030] According to some embodiments, by placing a first pattern below a color filter in at least one emission region of the emission region of a first pixel, the color filter can be formed to have a higher height at the central portion and an overall convex shape. Therefore, the side brightness and / or side color of the first pixel can be adjusted or improved.

However, the inventive concept may be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the inventive concept to those skilled in the art.

[0055] It will also be understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element or layer, or an intervening layer may also be present. Throughout the specification, the same reference numerals indicate the same parts.

[0056] It should be understood that although the terms "first," "second," etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the teachings of the inventive concept, the first element discussed below may be referred to as the second element. Similarly, the second element may also be referred to as the first element.

[0057] Features of each of the various embodiments of this disclosure may be combined with each other in part or in whole, and may interact with each other in a variety of technical ways, and the respective embodiments may be implemented independently of each other or may be implemented together in association with each other.

In one embodiment, the display device may be a light-emitting display device including light-emitting elements such as inorganic light-emitting diodes or organic light-emitting diodes, but the configuration of the display device is not limited thereto. For example, although a light-emitting display device including organic light-emitting diodes is described as a display device to which the embodiment can be applied, the apparatus or field to which the embodiment can be applied is not limited thereto. For example, the embodiment can also be applied to other types of display devices.

[0061] The shape of electronic device 1 can be modified in various ways. For example, electronic device 1 can have shapes such as a rectangle extending in the horizontal direction, a rectangle extending in the vertical direction, a square shape, a substantially quadrilateral shape with rounded corners, other polygonal shapes, and circular shapes. In one embodiment, the shape of the display area DA of electronic device 1 can be similar to, but is not limited to, the overall shape of electronic device 1. Figure 1 The example shown is an electronic device 1 having a rectangular shape that is longer in the second direction DR2 than in the first direction DR1.

[0062] Electronic device 1 may include a display area DA and a non-display area NDA. The display area DA is the area where an image can be displayed, and the non-display area NDA is the area where an image is not displayed. The display area DA may also be referred to as an active area, and the non-display area NDA may also be referred to as a passive area. The display area DA may substantially occupy the center of electronic device 1.

[0063] The display area DA may include a first display area DA1, a second display area DA2, and a third display area DA3. The second display area DA2 and the third display area DA3 are areas in which components for performing various functions of the electronic device 1 are disposed, and the second display area DA2 and the third display area DA3 may correspond to component areas. Although Figure 1 An embodiment in which the electronic device 1 includes two component regions is shown, but the number or location of the component regions is not limited. The first display region DA1 may be an area of ​​the display region DA where no components are disposed.

[0064] Figure 2 This is a perspective view showing a display device included in an electronic device according to one embodiment.

[0065] Reference Figure 1 and Figure 2 According to one embodiment, the electronic device 1 may include a display device 10. The display device 10 provides a screen for the electronic device 1. The display device 10 may have a planar shape similar to the shape of the electronic device 1. For example, the display device 10 may have a shape similar to a rectangle having a short side in a first direction DR1 and a long side in a second direction DR2. The edges where the short side in the first direction DR1 and the long side in the second direction DR2 intersect may be rounded, but are not limited thereto, and may form right angles. The planar shape of the display device 10 is not limited to a quadrilateral shape, and may have other polygonal shapes, circular shapes, elliptical shapes, or other shapes.

[0066] The display device 10 may include a display panel 100, a display driver 200, a circuit board 300, and a touch driver 400.

[0067] Display panel 100 may include a main area MA and a sub-area SBA.

[0068] The main area MA may include a display area DA containing pixels for displaying the image and a non-display area NDA disposed around the display area DA. The display area DA may be located at the center of the main area MA, and the non-display area NDA may surround the display area DA.

[0069] The display area DA may include a first display area DA1, a second display area DA2, and a third display area DA3. The display area DA may include the emission area of ​​a pixel and may emit light from the emission area.

[0070] The display panel 100 may include light-emitting elements and pixel circuitry (e.g., pixel circuitry including transistors and capacitors) for pixels, as well as a pixel-defining film surrounding the emitting region of the pixel. The light-emitting element for each pixel may be disposed in the emitting region of the corresponding pixel. In one embodiment, the light-emitting element may include, but is not limited to, an organic light-emitting diode (LED) containing an organic light-emitting layer, a quantum dot LED containing a quantum dot light-emitting layer, an inorganic LED containing inorganic semiconductors, and an ultra-miniature light-emitting diode such as a microLED or nanoLED.

[0071] The non-display area NDA can be an area outside the display area DA. The non-display area NDA can be defined as the edge area of ​​the main area MA of the display panel 100. In one embodiment, the non-display area NDA may include a gate driver (not shown) that supplies gate signals to the gate lines, and a fan-out line (not shown) that connects the display driver 200 to a data line disposed in the display area DA.

[0072] A sub-region SBA may be a region extending from one side of a main region MA. A sub-region SBA may comprise a flexible material capable of being bent, folded, or rolled. For example, when a sub-region SBA is bent (or folded), it may overlap with the main region MA in the thickness direction (e.g., the third direction DR3). For example, when the display device 10 is bent within a sub-region SBA, at least a portion of the sub-region SBA, including the area where the display driver 200 is located and the area where pads for connection to the circuit board 300 are located, may be positioned below the main region MA.

[0073] The sub-area SBA may include a display driver 200 and pad portions connected to the circuit board 300. In another embodiment, the sub-area SBA may be omitted, and the display driver 200 and pad portions may be located in the non-display area NDA. In another embodiment, the display driver 200 may be located on the circuit board 300 connected to the display panel 100 and may be electrically connected to the display panel 100 via the pad portions.

[0074] The display driver 200 can output drive signals and drive voltages for driving the display panel 100. For example, the display driver 200 can supply data voltages to data lines, drive voltages (e.g., first pixel voltage (or anode voltage) and second pixel voltage (or cathode voltage)) to power lines, and supply gate control signals to gate drivers. In one embodiment, the display driver 200 can be formed as an integrated circuit (IC) and mounted on the display panel 100 by a chip-on-glass (COG) method, a chip-on-plastic (COP) method, or an ultrasonic bonding method.

[0075] The circuit board 300 can be attached to the pad portion of the display panel 100 using an anisotropic conductive film (ACF) or the like. Leads of the circuit board 300 can be electrically connected to the pad portion of the display panel 100. In one embodiment, the circuit board 300 may be a flexible printed circuit board or a flexible film (such as a chip-on-film). In one embodiment, the circuit board 300 may be a rigid printed circuit board.

[0076] Touch driver 400 may be mounted on circuit board 300. Touch driver 400 may be connected to touch sensing layer of display panel 100. Touch driver 400 may supply each touch drive signal to touch electrodes of touch sensing layer and may sense the amount of capacitance change formed between touch electrodes. In one embodiment, touch drive signal may be pulse signal with a predetermined frequency. Touch driver 400 may detect whether a touch input has occurred and the coordinates of the touch input location based on the amount of capacitance change between touch electrodes. In one embodiment, touch driver 400 may be formed as integrated circuit (IC).

[0077] Figure 3 It was viewed from the side. Figure 2 A cross-sectional view of the display device. Figure 3 It shows Figure 2 The sub-area SBA of the display panel 100 in the display device 10, which is in a bent state.

[0078] Reference Figure 3 The display panel 100 may include a display layer DU, a touch sensing layer TSU, a color filter layer CFL, and a light-blocking component layer PML. Although in Figure 3 The color filter layer CFL and the light-blocking component layer PML are shown separately, but the implementation is not limited thereto. For example, the light-blocking component layer PML includes elements (e.g., Figure 4 The second light-blocking layer (BM2) is an element disposed in the color filter layer CFL, and can be regarded as an element disposed in the higher part of the elements of the color filter layer CFL.

[0079] The display layer DU may include a substrate SUB, a thin film transistor layer (TFTL), a light-emitting element layer (EML), and a packaging layer (TFEL).

[0080] The substrate SUB can be a base substrate or a base component. The substrate SUB can be a flexible substrate capable of being bent, folded, or rolled, but is not limited thereto. In one embodiment, the substrate SUB may include a polymer resin, such as polyimide (PI). In another embodiment, the substrate SUB may include a glass material or a metallic material.

[0081] A thin-film transistor layer (TFTL) may be disposed on a substrate SUB. The TFTL may include circuit elements constituting pixel circuitry, such as thin-film transistors and capacitors. The TFTL may also include wiring. For example, the TFTL may include gate lines, data lines, power lines, gate control lines, fan-out lines connecting the display driver 200 to the data lines, and leads connecting the display driver 200 to the pad portions. Each of the thin-film transistors may include a semiconductor region, a source electrode, a drain electrode, and a gate electrode. In one embodiment, when the display panel 100 includes a gate driver disposed in a non-display area NDA, the TFTL may also include circuit elements constituting the gate driver.

[0082] The thin-film transistor layer (TFTL) can be disposed in the display area (DA), the non-display area (NDA), and the sub-area (SBA). The circuit elements constituting the pixel circuit, as well as the gate lines, data lines, and power lines electrically connected to the pixel, can be disposed in the display area (DA) of the TFTL. The gate lines, data lines, and power lines can extend to the non-display area (NDA) of the TFTL and can be electrically connected to the gate driver, display driver 200, or pad portion, respectively. Gate control lines and fan-out lines can be disposed in the non-display area (NDA) of the TFTL. Leads can be disposed in the sub-area (SBA) of the TFTL.

[0083] A light-emitting element layer (EML) may be disposed on a thin-film transistor layer (TFTL). The EML may include a pixel defining film defining an emission region (or light-emitting element arrangement region) of a pixel and light-emitting elements disposed in the emission region. Each emission region may be disposed in each pixel region of a display region DA. For example, the pixel region of a corresponding pixel of a display region DA may include a pixel circuit region having circuit elements constituting the pixel circuit of the corresponding pixel and an emission region having the light-emitting element of the corresponding pixel. In one embodiment, the emission region and pixel circuit region of each pixel may overlap each other on a third-direction DR3.

[0084] The light-emitting element may include a first electrode and a second electrode facing each other, and a light-emitting layer between the first electrode and the second electrode. In one embodiment, the first electrode of the light-emitting element may correspond to... Figure 4 And the pixel electrode shown in the following figures, and the second electrode of the light-emitting element may correspond to Figure 9 The common electrode is shown in the following figures. In one embodiment, the light-emitting layer may be an organic light-emitting layer comprising organic materials. The light-emitting layer may include a hole transport layer, an organic light-emitting layer, and an electron transport layer. When a first pixel voltage (e.g., anode voltage) is applied to the first electrode of the light-emitting element through at least one of the thin-film transistors in each pixel circuit, and a second pixel voltage (e.g., cathode voltage) is applied to the second electrode of the light-emitting element through a power line, holes and electrons may recombine in the organic light-emitting layer, and the light-emitting element may emit light. In another embodiment, the light-emitting element may be another type of light-emitting element, such as a quantum dot light-emitting diode including a quantum dot light-emitting layer, an inorganic light-emitting diode including inorganic semiconductors, a micro light-emitting diode, or a nano light-emitting diode.

[0085] The encapsulation layer TFEL can cover the top and side surfaces of the light-emitting element layer EML and can protect the light-emitting element layer EML. In one embodiment, the encapsulation layer TFEL may include at least one inorganic layer and at least one organic layer for encapsulating the light-emitting element layer EML. For example, the encapsulation layer TFEL may include multiple inorganic encapsulation layers and an organic encapsulation layer between the inorganic encapsulation layers.

[0086] The touch sensing layer TSU can be disposed on the display layer DU. For example, the touch sensing layer TSU can be disposed on or formed on the encapsulation layer TFEL, or the touch sensing layer TSU can be disposed on a separate substrate and attached to the display layer DU using an adhesive layer.

[0087] The touch sensing layer (TSU) may include touch electrodes for sensing user touch input, and wiring for electrically connecting the touch electrodes to the touch driver 400. In one embodiment, the touch sensing layer (TSU) may sense user touch input using mutual capacitance or self-capacitance, and the touch electrodes may have a shape suitable for constituting a mutual capacitance or self-capacitance touch sensor. For example, the touch electrodes may include driving electrodes and sensing electrodes extending and / or connected in different directions to constitute a mutual capacitance touch sensor, or may include touch electrodes disposed at points corresponding to corresponding touch nodes or coordinates to constitute a self-capacitance touch sensor.

[0088] The touch electrodes of the touch sensing layer TSU can be located in the touch sensor area overlapping the display area DA. The area in the display area DA where the touch electrodes are located can be the touch sensor area. For example, the touch sensor area can be all or part of the display area DA. The wiring electrically connected to the touch electrodes of the touch sensing layer TSU can be located in the peripheral area overlapping the non-display area NDA.

[0089] A color filter layer (CFL) may be disposed on the touch sensing layer (TSU). The CFL may include color filters disposed in regions corresponding to the respective emission regions of a pixel. Each color filter selectively transmits light of a specific color or wavelength and blocks or absorbs light of different colors or wavelengths. In one embodiment, the CFL may further include a first light-blocking layer (or a first light-blocking pattern forming the first light-blocking layer) surrounding the emission region of the pixel. The first light-blocking layer may be formed separately from the color filters using individual light-blocking materials, or it may be formed by overlapping multiple color filters that selectively transmit light of different wavelengths.

[0090] The color filter layer (CFL) absorbs a portion of the light from outside the display device 10 to reduce reflected light caused by external light. The color filter layer (CFL) prevents color distortion caused by the reflection of external light.

[0091] In one embodiment, the color filter layer CFL can be disposed directly on the touch sensing layer TSU. Therefore, the display device 10 may not include a separate substrate for the color filter layer CFL and may have a further reduced thickness.

[0092] A light-blocking component layer (PML) may be disposed on a color filter layer (CFL). The PML may include a second light-blocking layer (or a second light-blocking pattern forming the second light-blocking layer) configured to correspond to a specific pixel of the display layer (DU). For example, the PML may include a second light-blocking layer configured to be adjacent to the emission region of the specific pixel and surrounding the emission region in a planar view.

[0093] A light-blocking member layer (PML) can limit the viewing angle of an image displayed by a particular pixel. For example, display device 10 includes a light-blocking member layer (PML) and thus can control visibility at a particular viewing angle and provide the user with side-view occlusion modes such as a privacy protection mode.

[0094] In some embodiments, the display device 10 may further include components disposed in the component area (e.g., Figure 1 and Figure 2The optical device 500 is located in the second display area DA2 or the third display area DA3. The optical device 500 can emit or receive light in the infrared, ultraviolet and visible light bands. For example, the optical device 500 can be an optical sensor that detects light incident on the display device 10, such as a proximity sensor, an illuminance sensor, and a camera sensor or image sensor.

[0095] Figure 4 This is a plan view showing the display area of ​​a display device according to one embodiment. For example, Figure 4 The illustration shows a pixel electrode AE ​​disposed in the display area DA of a display device 10 according to one embodiment, and a first light-blocking layer BM1 and a second light-blocking layer BM2 disposed around the pixel electrode AE.

[0096] Figure 5 This is a plan view illustrating a pixel electrode according to one embodiment. For example, Figure 5 The setting is shown Figure 4 The pixel electrode AE ​​in region A1 and the emission region EA where the pixel electrode AE ​​is located.

[0097] Figure 6 This is a plan view illustrating a pixel electrode, a first light-blocking layer, and a color filter according to one embodiment. For example, Figure 6 The setting is shown Figure 4 The pixel electrode AE ​​in region A1, and the first light-blocking layer BM1 and color filter CF disposed around the pixel electrode AE.

[0098] Figure 7 This is a plan view illustrating a pixel electrode and a second light-blocking layer according to one embodiment. For example, Figure 7 The setting is shown Figure 4 The pixel electrode AE ​​in region A1 and the second light-blocking layer BM2 disposed around the pixel electrode AE.

[0099] Reference Figures 4 to 7 The display device 10 may include pixels PX disposed in the display area DA. In one embodiment, pixels PX may be arranged on a fourth direction DR4 and a fifth direction DR5 between the first direction DR1 and the second direction DR2. In one embodiment, the fourth direction DR4 and the fifth direction DR5 may be diagonal directions relative to the first direction DR1 and the second direction DR2.

[0100] The display area DA may include an emission area EA of pixel PX and a non-emission area surrounding the emission area EA. In describing the implementation, the non-emission area may refer to the remaining area of ​​the display area DA excluding the emission area EA. For example, a non-emission area, which is a region disposed around and between the respective emission areas EA, may be a region provided with… Figure 4and Figure 6 The area of ​​the first light-blocking layer BM1. The pixel area where each pixel PX is set may include the emission area EA of the corresponding pixel PX and the non-emission area directly set around the emission area EA.

[0101] In one embodiment, each of the pixels PX may include a plurality of pixel electrodes AE. For example, each of the pixels PX may include a first pixel electrode AE1, a second pixel electrode AE2, and a third pixel electrode AE3. In one embodiment, a pixel PX may include one first pixel electrode AE1, two second pixel electrodes AE2, and one third pixel electrode AE3. However, the embodiments are not limited thereto, and the number of pixel electrodes AE disposed in the pixel PX may vary.

[0102] A pixel electrode AE ​​may be the first electrode, for example, an anode electrode, of the light-emitting element included in each pixel PX. In one embodiment, a pixel PX may include a plurality of light-emitting elements and a plurality of pixel circuits electrically connected to the plurality of light-emitting elements respectively. Each pixel circuit may be electrically connected to at least one light-emitting element. Each pixel circuit and at least one light-emitting element connected to that pixel circuit may constitute each sub-pixel.

[0103] Figures 4 to 7 Each pixel electrode AE ​​shown may be the entire pixel electrode AE, or a portion of the pixel electrode AE ​​exposed in the area where the pixel-defining film is opened. For example, Figures 4 to 7 Each pixel electrode AE ​​shown may have a size and / or shape corresponding to an opening in the pixel-defined film corresponding to each emission region EA. A light-emitting layer of a light-emitting element and a second electrode (e.g., a common electrode) may be disposed on each pixel electrode AE.

[0104] In one embodiment, a pixel PX may include multiple light-emitting elements that emit light of different colors. For example, a light-emitting element including a first pixel electrode AE1 (e.g., a first light-emitting element) may emit light of a first color (e.g., red light). A light-emitting element including a second pixel electrode AE2 (e.g., a second light-emitting element) may emit light of a second color (e.g., green light), and a light-emitting element including a third pixel electrode AE3 (e.g., a third light-emitting element) may emit light of a third color (e.g., blue light). Therefore, a pixel PX may emit any one of the first, second, and third colors of light, or a mixture of at least two of the first, second, and third colors of light. For example, all the light-emitting elements included in a pixel PX may emit light such that white light can be emitted from the pixel PX. However, the type, number, and arrangement of the pixel electrodes AE constituting a pixel PX and the light-emitting elements including the pixel electrodes AE may vary depending on the embodiment.

[0105] like Figure 5 As shown, a pixel electrode AE ​​can be disposed in the emission region EA of each pixel PX. Each pixel PX may include multiple emission regions EA, including a first emission region EA1 that emits light of a first color, a second emission region EA2 that emits light of a second color, and a third emission region EA3 that emits light of a third color. In one embodiment, a pixel PX may include one first emission region EA1, two second emission regions EA2, and one third emission region EA3, but the embodiment is not limited thereto. The first pixel electrode AE1 may be disposed in the first emission region EA1, the second pixel electrode AE2 may be disposed in the second emission region EA2, and the third pixel electrode AE3 may be disposed in the third emission region EA3. A light-emitting element including each pixel electrode AE ​​can be disposed in each emission region EA.

[0106] In one embodiment, each emission region EA may include the area of ​​each pixel electrode AE ​​exposed by an opening formed in the pixel-defining film. For example, each emission region EA may be defined primarily by the pixel-defining film. Furthermore, each emission region EA, as a region not blocked by the first light-blocking layer BM1 and the second light-blocking layer BM2, may be a light-transmitting region through which light generated from the light-emitting element including each pixel electrode AE ​​is transmitted. For example, as... Figure 6 As shown, each emission region EA corresponds to an opening OP in the first light-blocking layer BM1.

[0107] In description Figures 4 to 7 In this implementation, the area of ​​the light-emitting element exposed by the opening OP of the first light-blocking layer BM1 is defined as the emitting region EA, and the light-blocking area where the first light-blocking layer BM1 is disposed is defined as the non-emitting region. However, the criteria used to distinguish the emitting region EA from the non-emitting region can be changed. For example, the area of ​​the pixel electrode AE ​​exposed by the opening of the pixel defining film can be defined as the emitting region EA.

[0108] In one embodiment, the pixel electrode AE ​​may be arranged to have Configuration, for example, diamond Configuration. For example, the first pixel electrode AE1 and the third pixel electrode AE3 may be spaced apart from each other in the second direction DR2, and may be arranged alternately in the first direction DR1 and the second direction DR2. In each pixel PX, the first pixel electrode AE1 and the third pixel electrode AE3 may be spaced apart from each other in the second direction DR2, and the first pixel electrode AE1 and the third pixel electrode AE3 may be spaced apart from the second pixel electrode AE2 in the fourth direction DR4 or the fifth direction DR5. The second pixel electrode AE2 may be arranged repeatedly along the first direction DR1 and the second direction DR2. The second pixel electrode AE2 and the first pixel electrode AE1, or the second pixel electrode AE2 and the third pixel electrode AE3, may be arranged alternately along the fourth direction DR4 or the fifth direction DR5. However, the implementation is not limited to this, and the arrangement of the pixel electrodes AE may be varied.

[0109] In one embodiment, the sizes (e.g., areas) of the first pixel electrode AE1, the second pixel electrode AE2, and the third pixel electrode AE3 may be different from each other. For example, the area of ​​the third pixel electrode AE3 may be larger than the area of ​​the first pixel electrode AE1 and the area of ​​the second pixel electrode AE2, and the area of ​​the first pixel electrode AE1 may be larger than the area of ​​the second pixel electrode AE2. The intensity of light emitted from each emission region EA can be varied according to the area of ​​each pixel electrode AE ​​in which the emission region EA is located. Therefore, the color of the image displayed on the display device 10 or the electronic device 1 can be controlled by adjusting the area of ​​each pixel electrode AE ​​and the emission region EA including it. Although Figures 4 to 7 An embodiment in which the third pixel electrode AE3 has the largest area is shown, but the embodiment is not limited thereto. For example, the size (e.g., area) of the pixel electrode AE ​​and the emitting region EA including it can be freely adjusted according to the color of the image required by the display device 10 or electronic device 1. Furthermore, the area of ​​the pixel electrode AE ​​and the emitting region EA may be related to light efficiency, the lifetime of the light-emitting element ED, or the like, and may be subject to a trade-off with the reflection of external light. Taking the above factors into consideration, the area of ​​the pixel electrode AE ​​can be appropriately adjusted.

[0110] In one implementation, the size of the pixel electrodes AE of pixel PX can be uniform. For example, the size (or the aperture ratio of the pixel defining film, or the size of the opening of the pixel defining film exposing the first pixel electrodes AE1, second pixel electrodes AE2, and third pixel electrodes AE3 of the first pixel PX1) can be substantially the same as the size (or the aperture ratio of the pixel defining film, or the size of the opening of the pixel defining film exposing the first pixel electrodes AE1, second pixel electrodes AE2, and third pixel electrodes AE3 of the second pixel PX2) of the second pixel PX2.

[0111] In one implementation, the dimensions (e.g., areas) of the first pixel electrode AE1, the second pixel electrode AE2, and the third pixel electrode AE3 of each pixel PX may be different from each other. For example, the area of ​​the third pixel electrode AE3 may be larger than the area of ​​the first pixel electrode AE1 and the area of ​​the second pixel electrode AE2, and the area of ​​the first pixel electrode AE1 may be larger than the area of ​​the second pixel electrode AE2. The intensity of light emitted from each emission region EA may vary depending on the area of ​​each pixel electrode AE ​​disposed in that emission region EA.

[0112] like Figure 6 As shown, the emission region EA of pixel PX can be surrounded by a first light-blocking layer BM1. Furthermore, a color filter CF can be disposed within the emission region EA of pixel PX. The color filter CF can be disposed within the light-emitting element layer including the light-emitting element of pixel PX (e.g., ...). Figure 3 On the light-emitting element layer (EML).

[0113] A first light-blocking layer BM1 may be entirely disposed within the display area DA and may include an opening OP corresponding to the emission area EA of pixel PX. For example, the first light-blocking layer BM1 may be disposed in a non-emission area surrounding the emission area EA and may include an opening OP that exposes the emission area EA. In a plan view, the first light-blocking layer BM1 may include a first opening OP1 exposing the first emission area EA1, a second opening OP2 exposing the second emission area EA2, and a third opening OP3 exposing the third emission area EA3, and may surround the first emission area EA1, the second emission area EA2, and the third emission area EA3. The first light-blocking layer BM1 may block other portions of the display area DA besides the first emission area EA1, the second emission area EA2, and the third emission area EA3 (e.g., non-emission areas).

[0114] The opening OP of the first light-blocking layer BM1 can be disposed in the region corresponding to the pixel electrode AE, or in the portion of the pixel electrode AE ​​exposed by the opening of the pixel-defining film. The first opening OP1 of the first light-blocking layer BM1 can be disposed in the region corresponding to the corresponding first pixel electrode AE1. The second opening OP2 of the first light-blocking layer BM1 can be disposed in the region corresponding to the corresponding second pixel electrode AE2. The third opening OP3 of the first light-blocking layer BM1 can be disposed in the region corresponding to the corresponding third pixel electrode AE3. In a pixel region having one pixel PX, one first opening OP1, two second openings OP2, and one third opening OP3 can be formed in the first light-blocking layer BM1.

[0115] In a planar view, each of the openings OP in the first light-blocking layer BM1 may be larger than the corresponding pixel electrode AE ​​(or the portion of the corresponding pixel electrode AE ​​not covered by the pixel defining film). For example, in a planar view, the area of ​​the first opening OP1 may be larger than the area of ​​the first pixel electrode AE1, the area of ​​the second opening OP2 may be larger than the area of ​​the second pixel electrode AE2, and the area of ​​the third opening OP3 may be larger than the area of ​​the third pixel electrode AE3. In one embodiment, the areas of the first opening OP1, the second opening OP2, and the third opening OP3 of the first light-blocking layer BM1 may be different from each other. For example, the areas of the first opening OP1, the second opening OP2, and the third opening OP3 may correspond to the areas of the first pixel electrode AE1, the second pixel electrode AE2, and the third pixel electrode AE3, respectively. Furthermore, the dimensions (e.g., areas) of the first emitting region EA1, the second emitting region EA2, and the third emitting region EA3 may be different to correspond to the areas of the first opening OP1, the second opening OP2, and the third opening OP3 of the first light-blocking layer BM1, respectively. For example, the size of the second transmission region EA2 may be smaller than the size of each of the first transmission region EA1 and the third transmission region EA3, and the size of the third transmission region EA3 may be larger than the size of each of the first transmission region EA1 and the second transmission region EA2.

[0116] The display area DA may include at least two types of pixels PX. For example, the display area DA may include a first pixel PX1 and a second pixel PX2. The light emission angle and / or viewing angle of the first pixel PX1 and the second pixel PX2 may be different. For example, the first pixel PX1 may be a pixel PX that provides a wider range of light emission angle and / or viewing angle, and the second pixel PX2 may be a pixel PX that provides a narrower range of light emission angle and / or viewing angle.

[0117] In one implementation, the first pixel PX1 may be driven only in a first emission mode and may be turned off or not emit light in a second emission mode. The second pixel PX2 may be driven in both the first and second emission modes. The first emission mode may be a general mode in which the viewing angle of the image displayed in the display area DA is unrestricted (e.g., a wide viewing angle mode), and the second emission mode may be a side-view occlusion mode in which the viewing angle of the image displayed in the display area DA is restricted (e.g., a privacy protection mode or a security mode).

[0118] In one embodiment, the first pixel PX1 and the second pixel PX2 may be arranged alternately along the fourth direction DR4 and the fifth direction DR5. Furthermore, the first pixel PX1 may be arranged repeatedly along the first direction DR1 and the second direction DR2, and the second pixel PX2 may be arranged repeatedly along the first direction DR1 and the second direction DR2. For example, the first pixel PX1 and the second pixel PX2 may be arranged alternately and uniformly distributed throughout the entire display area DA. However, the embodiment is not limited to this, and the arrangement shape of the first pixel PX1 and the second pixel PX2 may be varied.

[0119] In one embodiment, the separation distance between the opening OP of the first light-blocking layer BM1 in the first pixel PX1 and the pixel electrode AE ​​(or the difference between the size of the opening OP of the first light-blocking layer BM1 in the first pixel PX1 and the size of the emitting region EA) may be different from the separation distance between the opening OP of the first light-blocking layer BM1 and the pixel electrode AE ​​in the second pixel PX2 (or the difference between the size of the opening OP of the first light-blocking layer BM1 in the second pixel PX2 and the size of the emitting region EA). For example, in a planar view, the separation distance between the opening OP of the first light-blocking layer BM1 in the first pixel PX1 and the pixel electrode AE ​​(or the difference between the diameter of the opening OP of the first light-blocking layer BM1 in the first pixel PX1 and the diameter of the pixel electrode AE) may be greater than the separation distance between the opening OP of the first light-blocking layer BM1 in the second pixel PX2 (or the difference between the diameter of the opening OP of the first light-blocking layer BM1 in the second pixel PX2 and the diameter of the pixel electrode AE). For example, compared to the light-emitting element including the pixel electrode AE ​​of the first pixel PX1, the first light-blocking layer BM1 can surround the light-emitting element including the pixel electrode AE ​​of the second pixel PX2 at a shorter distance. Furthermore, the size of the opening OP of the first light-blocking layer BM1 defining the emission region EA of the first pixel PX1 can be larger than the size of the opening OP of the first light-blocking layer BM1 defining the emission region EA of the second pixel PX2. Therefore, the light emission angle or viewing angle of the second pixel PX2 can be smaller than that of the first pixel PX1. In one embodiment, the light emission angle or viewing angle of the second pixel PX2 can be controlled (e.g., limited) by the size or position of the opening OP of the second light-blocking layer BM2 and the first light-blocking layer BM1.

[0120] In one embodiment, the size of the emission region EA of the first pixel PX1 (or the aperture ratio of the first pixel PX1) may be larger than the size of the emission region EA of the second pixel PX2 (or the aperture ratio of the second pixel PX2). For example, since the first light-blocking layer BM1 surrounds the pixel electrode AE ​​of the second pixel PX2 at a shorter distance, the size (e.g., area) of the emission region EA of the second pixel PX2 may be smaller than the size (e.g., area) of the emission region EA of the first pixel PX1. In one embodiment, the area occupied by each first pixel PX1 and each second pixel PX2 in the display area DA may be substantially the same. Therefore, the size of the non-emitting region of the second pixel PX2 may be larger than the size of the non-emitting region of the first pixel PX1.

[0121] The color filter CF can be disposed within the corresponding emission region EA, and can also be disposed around the emission region EA. For example, the color filter CF can cover the pixel electrode AE ​​disposed in the corresponding emission region EA and the light-emitting element including the pixel electrode AE, and can extend to the non-emission region surrounding the emission region EA.

[0122] The color filter CF may include a first color filter CF1 disposed in a first emission region EA1, a second color filter CF2 disposed in a second emission region EA2, and a third color filter CF3 disposed in a third emission region EA3. The color filter CF may contain a colorant, such as a dye or pigment, that absorbs light in wavelength bands other than a specific wavelength band. The first color filter CF1 may transmit light of a first color emitted from the light-emitting element in the first emission region EA1 and may absorb and / or block light of another color (e.g., second and third colors). For example, each first color filter CF1 may be a red color filter that selectively transmits only red light emitted from the light-emitting element disposed in each first emission region EA1. The second color filter CF2 may transmit light of a second color emitted from the light-emitting element in the second emission region EA2 and may absorb and / or block light of another color (e.g., first and third colors). For example, each second color filter CF2 may be a green color filter that selectively transmits only green light emitted from the light-emitting element disposed in each second emission region EA2. The third color filter CF3 can transmit light of a third color emitted from the light-emitting element in the third emission region EA3, and can absorb and / or block light of another color (e.g., light of the first color and light of the second color). For example, each third color filter CF3 can be a blue color filter that selectively transmits only blue light emitted from the light-emitting element disposed in each third emission region EA3.

[0123] Color filters CF can be formed as separate patterns corresponding to the respective emission regions EA, or they can be formed entirely within the display region DA. For example, each first color filter CF1 can be formed as an isolated pattern covering each first emission region EA1 and its periphery, each second color filter CF2 can be formed as an isolated pattern covering each second emission region EA2 and its periphery, and each third color filter CF3 can be formed as an isolated pattern covering each third emission region EA3 and its periphery. Alternatively, the first color filter CF1 may include openings formed in the regions corresponding to the second emission regions EA2 and EA3, the second color filter CF2 may include openings formed in the regions corresponding to the first emission regions EA1 and EA3, and the third color filter CF3 may include openings formed in the regions corresponding to the first emission regions EA1 and EA2.

[0124] In one embodiment, the first light-blocking layer BM1 may be formed as a light-blocking pattern other than the color filter CF, or it may be formed as part of the color filter CF. For example, the display device 10 may include a first light-blocking layer BM1 formed as a light-blocking pattern that is not the color filter CF, or it may include a first light-blocking layer BM1 formed by overlapping color filters CF that block different colors of light in a non-emission area around the emission area EA.

[0125] In one embodiment, the first light-blocking layer BM1 and the color filter CF may be disposed on the display layer DU. For example, the first light-blocking layer BM1 and the color filter CF may be disposed on... Figure 3 The color filter layer CFL is located in the display layer DU. Since the color filter CF and the first light-blocking layer BM1 are disposed on the display layer DU, the intensity of reflected light caused by external light can be reduced.

[0126] like Figure 7 As shown, the second light-blocking layer BM2 may be disposed in some of the pixels PX disposed in the display area DA. For example, the second pixel PX2 may include the second light-blocking layer BM2. The second light-blocking layer BM2 may not be disposed in the first pixel PX1.

[0127] The second light-blocking layer BM2 may surround the emission regions EA of some of the pixels PX. For example, the second light-blocking layer BM2 may be disposed in the non-emission region of the second pixel PX2 and may surround the emission region EA of each of the second pixels PX2. For example, the second light-blocking layer BM2 may surround the first emission region EA1, the second emission region EA2, and the third emission region EA3 of each of the second pixels PX2.

[0128] In one embodiment, the second light-blocking layer BM2 may be disposed on the first light-blocking layer BM1 and the color filter CF. For example, the second light-blocking layer BM2 may be disposed on... Figure 3 The light-blocking layer BM2 is located within the light-blocking component layer PML. In a plan view, the second light-blocking layer BM2 may overlap a portion of the first light-blocking layer BM1. For example, the second light-blocking layer BM2, disposed on a portion of the first light-blocking layer BM1, may be disposed within a portion of the non-emissive region (e.g., a portion of the non-emissive region of each of the second pixels PX2). Since the second light-blocking layer BM2 is disposed on the color filter layer CFL, the light emission angle or viewing angle of the second pixel PX2 can be adjusted or limited.

[0129] The light emission angle or viewing angle of the second pixel PX2 can be adjusted or changed by at least one of the following: the size of the opening OP of the first light-blocking layer BM1, the separation distance between the first light-blocking layer BM1 and the pixel electrode AE ​​of the second pixel PX2, the presence / absence of the second light-blocking layer BM2, and the separation distance between the second light-blocking layer BM2 and the pixel electrode AE ​​of the second pixel PX2. For example, by providing the second light-blocking layer BM2 in the second pixel PX2 to block at least a portion of the side light emitted from the second pixel PX2, the light emission angle or viewing angle of the second pixel PX2 can be further reduced.

[0130] In one embodiment, the second light-blocking layer BM2 disposed in a second pixel PX2 can be formed into a pattern. For example, the second light-blocking layer BM2 disposed in a second pixel PX2 may include a central portion BM2A surrounding a first emission region EA1, a second emission region EA2, and a third emission region EA3, and an edge portion BM2B connecting the central portion BM2A. The central portion BM2A of the second light-blocking layer BM2 may include a corresponding opening corresponding to the corresponding emission region EA, and may have a shape surrounding the emission region EA (e.g., an annular shape). The edge portion BM2B of the second light-blocking layer BM2 may be disposed between the central portions BM2A, and may be integrally formed with the central portions BM2A. Therefore, in the pixel process for forming the pixel PX, the second light-blocking layer BM2 can be prevented from deviating from a predetermined position or being peeled off, and the second light-blocking layer BM2 can be formed more stably.

[0131] As described above, a display device 10 according to one embodiment may include a first pixel PX1 without a second light-blocking layer BM2 and a second pixel PX2 with a second light-blocking layer BM2, and its side visibility may be adjusted according to the emission mode. Depending on the viewing angle of the display device 10, the pattern of the second light-blocking layer BM2 (e.g., a second light-blocking pattern disposed in each second pixel PX2) may partially cover the pixel electrode AE ​​and may block the emission of light at a specific viewing angle. For example, when the display device 10 is viewed from the side, the second light-blocking layer BM2 may block light emitted obliquely from the second pixel PX2.

[0132] In a state where side visibility is unrestricted (which is the first emission mode of the display device 10), both the first pixel PX1 and the second pixel PX2 can emit light. Since both the first pixel PX1 and the second pixel PX2 emit light in the first emission mode, the display device 10 can provide a wide viewing angle. For example, regardless of the direction in which the display device 10 is viewed, the user can visually identify light emitted from at least the first pixel PX1.

[0133] On the other hand, in a state where side visibility is desired (which is the second emission mode of the display device 10), the first pixel PX1 may not emit light, and only the second pixel PX2 may emit light. Since only the second pixel PX2 emits light in the second emission mode, light emitted from the opening OP of the first light-blocking layer BM1 can be blocked by the second light-blocking layer BM2 at a specific viewing angle. Since the first pixel PX1 does not emit light, the image of the display device 10 in the second emission mode can only be visually recognized by a user viewing from the front of the display area DA, and cannot be visually recognized by a user viewing from an angle larger than the specific viewing angle or from the side. Therefore, the display device 10 can provide the user with a side viewing angle occlusion mode, such as a privacy protection mode.

[0134] In the second emission mode of the display device 10, light leakage may occur from the second pixel PX2, depending on the degree to which light emitted obliquely from the pixel electrode AE ​​of the second pixel PX2 is blocked by the second light-blocking layer BM2. However, in a display device 10 according to one embodiment, the pattern of the second light-blocking layer BM2 may have a shape corresponding to the shape of the pixel electrode AE, and may be configured to surround the emission area EA on which the pixel electrode AE ​​is disposed. In the second emission mode, when viewing the display device 10, the degree to which the pixel electrode AE ​​of the second pixel PX2 is blocked can be uniform across all viewing angles, and light leakage from the light-emitting element including the specific pixel electrode AE ​​can be prevented.

[0135] Furthermore, in a display device 10 according to one embodiment, the second light-blocking layer BM2 is configured to correspond to the pixel electrode AE ​​of the second pixel PX2, and therefore can be configured not to affect other adjacent pixels, such as the first pixel PX1. Thus, in the first emission mode, the second light-blocking layer BM2 can substantially not block light emitted from the emission region EA of the first pixel PX1.

[0136] Figure 8 This is a plan view showing the display area of ​​a display device according to one embodiment. For example, Figure 8 The setting is shown Figure 4The touch electrode TL, pixel electrode AE, first light-blocking layer BM1, color filter CF, and second light-blocking layer BM2 in region A1.

[0137] Apart from Figures 4 to 7 In addition, refer to Figure 8 The display device 10 may also include touch electrodes TL disposed between pixel electrodes AE. Although Figure 8 The setting is shown Figure 4 The general shape of the touch electrode TL in region A1 is shown, but multiple touch electrodes TL can be provided in the display region DA. For example, when the display device 10 includes a mutual capacitance type touch sensor, multiple touch electrodes TL including driving electrodes and sensing electrodes can be provided in the display region DA.

[0138] In one embodiment, the touch electrode TL may be formed as a mesh pattern including an opening in the emission region EA of the exposed pixel PX. For example, each touch electrode TL or each of the plurality of electrode units constituting the touch electrode TL may be a mesh pattern formed by fine lines extending in the fourth direction DR4 or the fifth direction DR5 respectively and overlapping with the first light-blocking layer BM1.

[0139] In one implementation, the resolution of the pixel PX and the resolution of the touch electrode TL may be different. For example, each touch electrode TL may be disposed in an area where multiple pixels PX are provided. Figure 8 The touch electrode TL shown can be set in Figure 4 A touch electrode TL in region A1 or an electrode unit forming a touch electrode TL. The shape, number, resolution, and / or structure of the touch electrode TL may vary depending on the implementation. In one implementation, the touch electrode TL may be connected or extended in a desired shape or direction by a corresponding bridging pattern.

[0140] In one embodiment, the touch electrode TL may be disposed on the display layer DU. For example, the touch electrode TL may be disposed on... Figure 3 In the touch sensing layer TSU, touch input can be sensed in the display area DA via the touch electrode TL.

[0141] Figure 9 This is a cross-sectional view showing a display device according to one embodiment. For example, Figure 9 A portion of the display device 10 is shown, which is connected to the side along the edge. Figures 4 to 8 The first pixel PX1 is cut off by the line X1-X1'.

[0142] Figure 10 This is a cross-sectional view showing a display device according to one embodiment. For example, Figure 10 A portion of the display device 10 is shown, which is connected to the side along the edge. Figures 4 to 8The cross-section of the second pixel PX2 is intercepted by the line X2-X2'.

[0143] Apart from Figures 1 to 8 In addition, refer to Figure 9 and Figure 10 According to one embodiment, the display panel 100 of the display device 10 may include a display layer DU, a touch sensing layer TSU, a color filter layer CFL, and a light-blocking member layer PML. The display layer DU may include a substrate SUB, a thin-film transistor layer TFTL, a light-emitting element layer EML, and a packaging layer TFEL. The touch sensing layer TSU may include touch electrodes TL and bridging patterns TBR. The color filter layer CFL may include a first light-blocking layer BM1 and a color filter CF. The light-blocking member layer PML may include a second light-blocking layer BM2 and an outer coating OC.

[0144] The substrate SUB can be a base substrate or a base component. In one embodiment, the substrate SUB can be a flexible substrate that can be bent, folded, or rolled up, but is not limited thereto.

[0145] The thin-film transistor layer (TFTL) may include a first buffer layer (BF1), a lower metal layer (BML), a second buffer layer (BF2), a thin-film transistor (TFT), a gate insulating layer (GI), a first interlayer insulating layer (ILD1), a capacitor electrode (CPE), a second interlayer insulating layer (ILD2), a first connection electrode (CNE1), a first passivation layer (PAS1), a second connection electrode (CNE2), and a second passivation layer (PAS2). However, the embodiments are not limited to this, and the number or type of conductive and insulating layers forming the TFTL and / or the structure or type of the thin-film transistor (TFT) may vary depending on the embodiment.

[0146] The first buffer layer BF1 may be disposed on the substrate SUB. In one embodiment, the first buffer layer BF1 may include an inorganic membrane capable of preventing the penetration of air or moisture.

[0147] The lower metal layer BML may be disposed on the first buffer layer BF1. In one embodiment, the lower metal layer BML may be formed as a single layer or multiple layers made of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd) and copper (Cu) or alloys thereof.

[0148] The second buffer layer BF2 may cover the first buffer layer BF1 and the lower metal layer BML. In one embodiment, the second buffer layer BF2 may include an inorganic membrane capable of preventing the penetration of air or moisture.

[0149] Thin-film transistors (TFTs) may be disposed on the second buffer layer BF2 and may be provided to each of the pixel circuits (e.g., pixel circuits of sub-pixels) included in each pixel PX. Figure 9 and Figure 10The general shape of one of the thin-film transistor TFTs (e.g., a thin-film transistor TFT electrically connected to a first light-emitting element ED1, a second light-emitting element ED2, or a third light-emitting element ED3) provided to the corresponding pixel circuits (e.g., pixel circuits of a sub-pixel) of the first pixel PX1 and the second pixel PX2 is shown. Figure 9 and Figure 10 Each thin-film transistor (TFT) shown can be a switching transistor or a driving transistor constituting each pixel circuit. The TFT may include a semiconductor layer ACT, a source electrode SE, a drain electrode DE, and a gate electrode GE.

[0150] A semiconductor layer ACT may be disposed on the second buffer layer BF2. The semiconductor layer ACT may overlap with the lower metal layer BML and the gate electrode GE in the thickness direction, and may be insulated from the gate electrode GE by the gate insulating layer GI. A portion of the semiconductor layer ACT may become conductive to form the source electrode SE (or source region) and the drain electrode DE (or drain region).

[0151] The gate electrode GE can be disposed on the gate insulating layer GI. The gate electrode GE can overlap with the semiconductor layer ACT, wherein the gate insulating layer GI is located between the gate electrode GE and the semiconductor layer ACT.

[0152] A gate insulating layer GI may be disposed on the semiconductor layer ACT. For example, the gate insulating layer GI may cover the semiconductor layer ACT and the second buffer layer BF2, and may be disposed between the semiconductor layer ACT and the gate electrode GE. The gate insulating layer GI may include a contact hole through which the first connection electrode CNE1 passes.

[0153] The first interlayer insulating layer ILD1 may cover the gate electrode GE and the gate insulating layer GI. The first interlayer insulating layer ILD1 may include a contact hole through which the first connection electrode CNE1 passes. The contact hole of the first interlayer insulating layer ILD1 may be connected to the contact hole of the gate insulating layer GI and the contact hole of the second interlayer insulating layer ILD2.

[0154] A capacitor electrode CPE may be disposed on the first interlayer insulating layer ILD1. The capacitor electrode CPE may overlap with the gate electrode GE in the thickness direction. The capacitor electrode CPE and the gate electrode GE can form a capacitor. For example, the storage capacitor of each pixel circuit may be formed by the capacitor electrode CPE and the gate electrode GE.

[0155] The second interlayer insulating layer ILD2 may cover the capacitor electrode CPE and the first interlayer insulating layer ILD1. The second interlayer insulating layer ILD2 may include a contact hole through which the first connection electrode CNE1 passes. The contact hole of the second interlayer insulating layer ILD2 may be connected to the contact hole of the first interlayer insulating layer ILD1 and the contact hole of the gate insulating layer GI.

[0156] The first connection electrode CNE1 may be disposed on the second interlayer insulating layer ILD2. The first connection electrode CNE1 can electrically connect the drain electrode DE of the thin-film transistor TFT to the second connection electrode CNE2. When the type of the thin-film transistor TFT and / or the structure of the pixel circuit changes, the first connection electrode CNE1 can electrically connect the source electrode SE of the thin-film transistor TFT to the second connection electrode CNE2. The first connection electrode CNE1 can contact and / or connect to the drain electrode DE of the thin-film transistor TFT through contact holes formed in the second interlayer insulating layer ILD2, the first interlayer insulating layer ILD1, and the gate insulating layer GI.

[0157] The first passivation layer PAS1 may cover the first connection electrode CNE1 and the second interlayer insulating layer ILD2. The first passivation layer PAS1 may protect the thin-film transistor (TFT). The first passivation layer PAS1 may include a contact hole through which the second connection electrode CNE2 passes.

[0158] The second connection electrode CNE2 may be disposed on the first passivation layer PAS1. The second connection electrode CNE2 can electrically connect the first connection electrode CNE1 to the pixel electrode AE ​​of the light-emitting element ED. The second connection electrode CNE2 can contact and / or connect to the first connection electrode CNE1 through a contact hole formed in the first passivation layer PAS1. Furthermore, the second connection electrode CNE2 can contact and / or connect to the pixel electrode AE ​​of the light-emitting element ED through a contact hole formed in the second passivation layer PAS2. In another embodiment, the thin-film transistor layer TFTL may not include the second connection electrode CNE2, and the pixel electrode AE ​​of the light-emitting element ED may be directly connected to the first connection electrode CNE1 (or an electrode of the thin-film transistor TFT).

[0159] The second passivation layer PAS2 may cover the second connection electrode CNE2 and the first passivation layer PAS1. The second passivation layer PAS2 may include a contact hole through which the pixel electrode AE ​​of the light-emitting element ED passes. In another embodiment, the thin-film transistor layer TFTL may not include the second connection electrode CNE2 and the second passivation layer PAS2, and the pixel electrode AE ​​of the light-emitting element ED may be disposed on the first passivation layer PAS1.

[0160] The light-emitting element layer (EML) can be disposed on the thin-film transistor layer (TFTL). The EML may include light-emitting elements (EDs) and pixel defining films (PDLs). The light-emitting elements (EDs) may be disposed in the corresponding emission regions (EAs).

[0161] Each light-emitting element ED may include a pixel electrode AE ​​(e.g., a first electrode or anode electrode of the light-emitting element ED), a light-emitting layer EL, and a common electrode CE (e.g., a second electrode or cathode electrode of the light-emitting element ED). For example, a first light-emitting element ED1 disposed in each first emission region EA1 may include a first pixel electrode AE1 and a light-emitting layer EL and a common electrode CE sequentially disposed on the first pixel electrode AE1. A second light-emitting element ED2 disposed in each second emission region EA2 may include a second pixel electrode AE2 and a light-emitting layer EL and a common electrode CE sequentially disposed on the second pixel electrode AE2. A third light-emitting element ED3 disposed in each third emission region EA3 may include a third pixel electrode AE3 and a light-emitting layer EL and a common electrode CE sequentially disposed on the third pixel electrode AE3.

[0162] Pixel electrodes AE can be disposed on the second passivation layer PAS2. Different pixel electrodes AE can be arranged in different emission regions EA. For example, the first pixel electrode AE1, the second pixel electrode AE2, and the third pixel electrode AE3 of the first pixel PX1 can be disposed in the first emission region EA1, the second emission region EA2, and the third emission region EA3 of the first pixel PX1, respectively, and the first pixel electrode AE1, the second pixel electrode AE2, and the third pixel electrode AE3 of the second pixel PX2 can be disposed in the first emission region EA1, the second emission region EA2, and the third emission region EA3 of the second pixel PX2, respectively.

[0163] In one embodiment, at least a portion of each of the pixel electrodes AE may not be covered by the pixel defining film PDL. For example, a large portion of the region including the central portion of each first pixel electrode AE1 may not be covered by the pixel defining film PDL, a large portion of the region including the central portion of each second pixel electrode AE2 may not be covered by the pixel defining film PDL, and a large portion of the region including the central portion of each third pixel electrode AE3 may not be covered by the pixel defining film PDL. The edge portions of the pixel electrodes AE may be covered by the pixel defining film PDL.

[0164] The corresponding light-emitting layer EL can be disposed on the portion of the pixel electrode AE ​​that is not covered by the pixel-defining film PDL. Therefore, each light-emitting element ED can be disposed and / or formed in each emission region EA.

[0165] The pixel electrode AE ​​can be electrically connected to an electrode of the thin-film transistor TFT. For example, the pixel electrode AE ​​can be electrically connected to the drain electrode DE of the thin-film transistor TFT via a first connection electrode CNE1 and a second connection electrode CNE2.

[0166] The light-emitting layer EL can be disposed on the pixel electrode AE. In one embodiment, the light-emitting layer EL can be an organic light-emitting layer made of organic materials, but is not limited thereto.

[0167] In one embodiment, the light-emitting layers EL of the first light-emitting element ED1, the second light-emitting element ED2, and the third light-emitting element ED3 can emit light of different colors. For example, the light-emitting layer EL of the first light-emitting element ED1 can emit light of a first color (e.g., red light), the light-emitting layer EL of the second light-emitting element ED2 can emit light of a second color (e.g., green light), and the light-emitting layer EL of the third light-emitting element ED3 can emit light of a third color (e.g., blue light).

[0168] However, the implementation is not limited to this. For example, in another embodiment, the light-emitting layer EL of the light-emitting element ED can be formed as a common layer completely disposed on different pixel electrodes AE and pixel defining films PDL, and the light-emitting layers EL disposed on different pixel electrodes AE can emit light of the same color. In this case, the display device 10 may also include a color adjustment layer disposed on the light-emitting element ED (e.g., a color conversion layer including a wavelength conversion pattern and / or a color adjustment layer including a color filter CF).

[0169] A common electrode CE may be disposed on the light-emitting layer EL of each of the light-emitting elements ED. In one embodiment, the common electrode CE may be formed as a single common layer entirely disposed in the display area DA, and the light-emitting elements ED of the pixel PX may share a common electrode CE. The common electrode CE may receive a common voltage (e.g., a second pixel voltage or a cathode voltage).

[0170] The pixel defining film (PDL) may include an opening (OPN) corresponding to the emission region (EA) and may be disposed on a portion of the pixel electrode (AE) and the second passivation layer (PAS2). For example, the pixel defining film (PDL) may be disposed at least in the non-emission region (NEA) and may include a first opening (OPN1) disposed in each first emission region (EA1), a second opening (OPN2) disposed in each second emission region (EA2), and a third opening (OPN3) disposed in each third emission region (EA3).

[0171] In one embodiment, each of the openings OPN in the pixel-defining film PDL may have a smaller size than the size of the corresponding emission region EA in the emission region EA, and may be disposed in the corresponding emission region EA. However, the embodiment is not limited thereto. For example, each of the openings OPN in the pixel-defining film PDL may have a size substantially the same as the size of the corresponding emission region EA in the emission region EA. The pixel-defining film PDL may overlap with the first light-blocking layer BM1 and the second light-blocking layer BM2 in a planar view.

[0172] In one embodiment, the openings (OPNs) of the pixel-defining film (PDL) may have different sizes. For example, the openings (OPNs) of the PDL may have sizes corresponding to the sizes of the corresponding emission regions (EAs). For example, the size of each first opening (OPN1) (or a first aperture ratio corresponding to the first emission region EA1) may be larger than the size of each second opening (OPN2) (or a second aperture ratio corresponding to the second emission region EA2), and may be smaller than the size of each third opening (OPN3) (or a third aperture ratio corresponding to the third emission region EA3).

[0173] In one embodiment, the pixel-defined film (PDL) can be opened with substantially the same area in the first pixel region where each first pixel PX1 is disposed and in the second pixel region where each second pixel PX2 is disposed. For example, the size of the first opening OPN1 disposed in the first emission region EA1 of the first pixel PX1 and the size of the first opening OPN1 disposed in the first emission region EA1 of the second pixel PX2 can be substantially the same or similar. Similarly, the size of the second opening OPN2 disposed in the second emission region EA2 of the first pixel PX1 and the size of the second opening OPN2 disposed in the second emission region EA2 of the second pixel PX2 can be substantially the same or similar, and the size of the third opening OPN3 disposed in the third emission region EA3 of the first pixel PX1 and the size of the third opening OPN3 disposed in the third emission region EA3 of the second pixel PX2 can be substantially the same or similar. However, when the first light-blocking layer BM1 is opened more narrowly in the second pixel PX2 than in the first pixel PX1, the actual size of the emission region EA (e.g., the light-emitting region) of the second pixel PX2 can be smaller than the actual size of the emission region EA of the first pixel PX1.

[0174] In one embodiment, the pixel-defining film (PDL) may include a light-absorbing material to prevent light reflection. For example, the PDL may include a polyimide (PI)-based binder and pigments mixed therein with red, green, and blue pigments. Alternatively, the PDL may include a cardo-based binder resin and a mixture of lactam black pigment and blue pigment. Alternatively, the PDL may include carbon black.

[0175] The encapsulation layer TFEL can be disposed on the common electrode CE to cover the light-emitting element ED. In one embodiment, the encapsulation layer TFEL may include at least one inorganic film to prevent oxygen or moisture from penetrating into the light-emitting element layer EML, and may include at least one organic film to protect the light-emitting element layer EML from foreign matter such as dust.

[0176] In one embodiment, the encapsulation layer TFEL may include a first encapsulation layer TFE1, a second encapsulation layer TFE2, and a third encapsulation layer TFE3 sequentially disposed on the light-emitting element ED. The first encapsulation layer TFE1 and the third encapsulation layer TFE3 may be inorganic encapsulation layers, and the second encapsulation layer TFE2 disposed between the first encapsulation layer TFE1 and the third encapsulation layer TFE3 may be an organic encapsulation layer.

[0177] Each of the first encapsulation layer TFE1 and the third encapsulation layer TFE3 may include an inorganic insulating material. For example, each of the first encapsulation layer TFE1 and the third encapsulation layer TFE3 may include aluminum oxide, titanium oxide, tantalum oxide, hafnium oxide, zinc oxide, silicon oxide, silicon nitride, silicon oxynitride, and / or another inorganic insulating material.

[0178] The second encapsulation layer TFE2 may include an organic insulating material. For example, the second encapsulation layer TFE2 may include a polymer-based organic insulating material such as acrylic resin, epoxy resin, polyimide, or polyethylene, or may include another organic insulating material. The second encapsulation layer TFE2 may be formed by curing monomers or applying polymers.

[0179] The touch sensing layer TSU can be disposed on the encapsulation layer TFEL. For example, the touch sensing layer TSU can be disposed between the display layer DU and the color filter layer CFL. However, the implementation is not limited to this, and the position of the touch sensing layer TSU can be changed depending on the implementation. In another implementation, the touch sensing layer TSU and the display layer DU can be integrated, or the display device 10 may not include a separate touch sensing layer TSU. In this case, the color filter layer CFL can be disposed directly on the display layer DU.

[0180] The touch sensing layer TSU may include a first insulating layer SIL1, a second insulating layer SIL2, and a touch electrode TL. In one embodiment, the touch sensing layer TSU may further include at least one insulating layer covering the second insulating layer SIL2 and the touch electrode TL.

[0181] The touch sensing layer (TSU) may include a conductive pattern containing touch electrodes (TL). The conductive pattern may be a sensing pattern for sensing touch input. For example, the conductive pattern of the touch sensing layer (TSU) may be used to sense changes in electrical characteristics (e.g., changes in capacitance) based on touch input and to detect the touch input.

[0182] In one embodiment, the conductive pattern of the touch sensing layer TSU may further include bridging patterns TBR for connecting touch electrodes TL (or electrode units forming touch electrodes TL) disposed in the display area DA in a desired shape and / or structure. Each bridging pattern TBR may overlap a portion of at least one touch electrode TL (e.g., two electrode units included in the touch electrode TL and adjacent to each other) and may be electrically connected to the touch electrode TL.

[0183] In one embodiment, the conductive pattern of the touch sensing layer TSU may be disposed in the non-emitting region NEA surrounding the emitting region EA, and may overlap with the first light-blocking layer BM1. Therefore, the conductive pattern of the touch sensing layer TSU can be prevented from being visually recognized by the user.

[0184] In one embodiment, the touch sensing layer TSU may include multiple conductive layers. For example, the touch sensing layer TSU may include a first conductive layer (e.g., a lower conductive layer) containing a bridging pattern TBR and a second conductive layer (e.g., an upper conductive layer) containing touch electrodes TL. At least one insulating layer may be disposed between the first conductive layer and the second conductive layer. For example, a second insulating layer SIL2 may be disposed between the first conductive layer and the second conductive layer. In one embodiment, the first conductive layer may be disposed below the second insulating layer SIL2, and the second conductive layer may be disposed above the second insulating layer SIL2, but this disclosure is not limited thereto. For example, the arrangement order or position of the first conductive layer and the second conductive layer may be changed.

[0185] A first insulating layer SIL1 may be disposed on the encapsulation layer TFEL. The first insulating layer SIL1 may have both insulating and optical functions. In one embodiment, the first insulating layer SIL1 may include at least one inorganic film. In one embodiment, the first insulating layer SIL1 may be omitted.

[0186] The bridging pattern TBR can be disposed on the first insulating layer SIL1. The position of the bridging pattern TBR can be changed according to the implementation method.

[0187] A second insulating layer SIL2 may be disposed on the bridging pattern TBR. For example, the second insulating layer SIL2 may cover the bridging pattern TBR and the first insulating layer SIL1, and may be disposed between the touch electrode TL and the bridging pattern TBR. The second insulating layer SIL2 may include a contact hole through which the touch electrode TL (or the bridging pattern TBR) passes at the portion where the touch electrode TL and the bridging pattern TBR are joined.

[0188] The second insulating layer SIL2 may have both insulating and optical functions. In one embodiment, the second insulating layer SIL2 may be an inorganic film comprising at least one of a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, and an aluminum oxide layer.

[0189] The touch electrode TL (or a portion of the touch electrode TL in the display area DA) may be disposed on the second insulating layer SIL2. The touch electrode TL may include a conductive material and may be formed as a single layer or multiple layers. For example, the touch electrode TL may be formed as a single layer comprising molybdenum (Mo), titanium (Ti), copper (Cu), aluminum (Al), or indium tin oxide (ITO), or it may be formed as a multilayer having a stacked structure of aluminum and titanium (Ti / Al / Ti), a stacked structure of aluminum and ITO (ITO / Al / ITO), an Ag-Pd-Cu (APC) alloy, or a stacked structure of APC alloy and ITO (ITO / APC / ITO).

[0190] In one embodiment, the touch electrode TL may not overlap with the pixel electrode AE. For example, the touch electrode TL may be disposed in the non-emitting region NEA and may overlap with the pixel defining film PDL and the first light-blocking layer BM1.

[0191] In one embodiment, the first light-blocking layer BM1 may have a width sufficient to completely cover the touch electrode TL. In another embodiment, the touch electrode TL may be configured such that its center is almost aligned with the center of the first light-blocking layer BM1, and the gap from both sides of the touch electrode TL to the edge of the first light-blocking layer BM1 may be uniform.

[0192] The color filter layer (CFL) can be disposed on the light-emitting element layer (EML). For example, the color filter layer (CFL) can be disposed on the touch sensing layer (TSU) and can cover the light-emitting element layer (EML), the encapsulation layer (TFEL), and the touch sensing layer (TSU).

[0193] The color filter layer CFL may include a first light-blocking layer BM1, a color filter CF, and at least one passivation layer. For example, the color filter layer CFL may include a first light-blocking layer BM1, a color filter CF, a first passivation layer PSV1, and a second passivation layer PSV2.

[0194] although Figure 9 and Figure 10 An embodiment in which the first light-blocking layer BM1 and the color filter CF are formed separately from each other is shown, but the embodiment is not limited thereto. For example, the display device 10 according to another embodiment may not include separately formed... Figure 9 and Figure 10The first light-blocking layer BM1 can block light by arranging a first color filter CF1, a second color filter CF2, and a third color filter CF3 to overlap each other in the non-emissive region NEA. In this case, the first color filter CF1 can be disposed in the region corresponding to the first emitting region EA1 and the non-emissive region NEA, and includes openings configured to correspond to the second emitting region EA2 and the third emitting region EA3. The second color filter CF2 can be disposed in the region corresponding to the second emitting region EA2 and the non-emissive region NEA, and includes openings configured to correspond to the first emitting region EA1 and the third emitting region EA3. The third color filter CF3 can be disposed in the region corresponding to the third emitting region EA3 and the non-emissive region NEA, and includes openings configured to correspond to the first emitting region EA1 and the second emitting region EA2.

[0195] A first light-blocking layer BM1 may be disposed on the touch sensing layer TSU. The first light-blocking layer BM1 may be disposed in the non-emitting region NEA. The first light-blocking layer BM1 may cover the touch electrode TL. The first light-blocking layer BM1 may include a light-blocking material (e.g., a light-absorbing material) such as a black matrix material.

[0196] The first light-blocking layer BM1 may not cover the opening OP of the exposed pixel electrode AE. For example, as Figure 6 As shown, the first light-blocking layer BM1 may include a first opening OP1 in each first emission region EA1 that does not cover the first pixel electrode AE1, a second opening OP2 in each second emission region EA2 that does not cover the second pixel electrode AE2, and a third opening OP3 in each third emission region EA3 that does not cover the third pixel electrode AE3.

[0197] In one embodiment, the first light-blocking layer BM1 may have openings of different sizes in the first pixel PX1 and the second pixel PX2. For example, the area (or width) of the first opening OP1, the second opening OP2, and the third opening OP3 respectively disposed in the first emission region EA1, the second emission region EA2, and the third emission region EA3 of the first pixel PX1 may be larger than the area (or width) of the first opening OP1, the second opening OP2, and the third opening OP3 respectively disposed in the first emission region EA1, the second emission region EA2, and the third emission region EA3 of the second pixel PX2.

[0198] Therefore, the first light-blocking layer BM1 can have different widths in the non-emissive region NEA of the first pixel PX1 and the non-emissive region NEA of the second pixel PX2. For example, as Figure 9 and Figure 10As shown, the first light-blocking layer BM1 may have a first width Wb1 and a second width Wb2 in the non-emissive region NEA of the first pixel PX1 and the non-emissive region NEA of the second pixel PX2, respectively, and the first width Wb1 may be smaller than the second width Wb2. Therefore, the side light blocking rate of the second pixel PX2 may be higher than that of the first pixel PX1, and the light emission angle or viewing angle (e.g., side viewing angle) of the second pixel PX2 may be narrower than that of the first pixel PX1.

[0199] A color filter CF can be disposed on the touch sensing layer TSU and the first light-blocking layer BM1. The color filter CF can be disposed in the corresponding emission region EA and overlap with the corresponding light-emitting element ED. In one embodiment, the color filter CF can also be disposed around the corresponding emission region EA, and at least two color filters CF can overlap each other between adjacent emission regions EA.

[0200] A first color filter CF1 may be disposed in a first emission region EA1 and overlap with a first light-emitting element ED1. In one embodiment, an edge portion of the first color filter CF1 may be disposed around the first emission region EA1 and overlap with a portion of the first light-blocking layer BM1. For example, in a plan view, the edge portion of the first color filter CF1 may surround the first emission region EA1 and may be disposed on a portion of the first light-blocking layer BM1.

[0201] The second color filter CF2 may be disposed in the second emission region EA2 and overlap with the second light-emitting element ED2. In one embodiment, the edge portion of the second color filter CF2 may be disposed around the second emission region EA2 and overlap with a portion of the first light-blocking layer BM1. For example, in a plan view, the edge portion of the second color filter CF2 may surround the second emission region EA2 and may be disposed on a portion of the first light-blocking layer BM1.

[0202] A third color filter CF3 may be disposed within a third emission region EA3 and overlap with a third light-emitting element ED3. In one embodiment, an edge portion of the third color filter CF3 may be disposed around the third emission region EA3 and overlap with a portion of the first light-blocking layer BM1. For example, in a plan view, the edge portion of the third color filter CF3 may surround the third emission region EA3 and may be disposed on a portion of the first light-blocking layer BM1.

[0203] In one implementation, the color filter CF may have a thickness that is adjusted or optimized according to the light efficiency of the pixel PX. For example, the color filters CF may have different thicknesses than each other, or be optimized according to the light emission efficiency of the light generated from the respective light-emitting element ED (e.g., the color filter transmittance of the light generated from the respective light-emitting element ED).

[0204] In one embodiment, the first color filter CF1 may have a first thickness d1 adjusted according to the light emission efficiency of a first color light emitted from the first light-emitting element ED1, the second color filter CF2 may have a second thickness d2 adjusted according to the light emission efficiency of a second color light emitted from the second light-emitting element ED2, and the third color filter CF3 may have a third thickness d3 adjusted according to the light emission efficiency of a third color light emitted from the third light-emitting element ED3. The thickness of the first color filter CF1 disposed in the first emission region EA1 may generally be uniform. For example, the first color filter CF1 disposed in the first emission region EA1 of the first pixel PX1 and the first emission region EA1 of the second pixel PX2 may have substantially the same first thickness d1 in the respective emission region EA. The thickness of the second color filter CF2 disposed in the second emission region EA2 may generally be uniform. For example, the second color filter CF2 disposed in the second emission region EA2 of the first pixel PX1 and the second emission region EA2 of the second pixel PX2 may have substantially the same second thickness d2 in the respective emission region EA. The thickness of the third color filter CF3 disposed in the third emission region EA3 can be generally uniform. For example, the third color filter CF3 disposed in the third emission region EA3 of the first pixel PX1 and the third emission region EA3 of the second pixel PX2 can have substantially the same third thickness d3 in the respective emission region EA. When describing the embodiment, the thickness of the color filter CF can be compared with the central portion of the color filter CF disposed in the emission region EA. For example, the central portions of the first color filter CF1, the second color filter CF2, and the third color filter CF3 can have substantially the first thickness d1, the second thickness d2, and the third thickness d3, respectively.

[0205] In one embodiment, the first thickness d1 may be less than the second thickness d2 and the third thickness d3, and the second thickness d2 may be greater than the first thickness d1 and the third thickness d3. For example, the first color filter CF1 may have the thinnest thickness, and the second color filter CF2 may have the thickest thickness. The third color filter CF3 may have an intermediate thickness. However, the embodiment is not limited to this, and the thickness of the color filter CF may be varied according to the light emission efficiency of the corresponding light-emitting element ED, the optimal ratio of the first color light, the second color light, and the third color light emitted from the corresponding emission region EA, or various other factors.

[0206] The first passivation layer PSV1 and the second passivation layer PSV2 can be sequentially disposed on the first light-blocking layer BM1 and the color filter CF. The first passivation layer PSV1 and the second passivation layer PSV2 can be completely disposed in the display area DA, thereby flattening the step portion caused by the color filter CF and the first light-blocking layer BM1.

[0207] The first passivation layer PSV1 and the second passivation layer PSV2 can be light-transmitting layers. For example, the first passivation layer PSV1 and the second passivation layer PSV2 may comprise colorless, light-transmitting organic materials, such as acrylic resin.

[0208] The light-blocking component layer PML can be disposed on the color filter layer CFL. The light-blocking component layer PML may include a second light-blocking layer BM2 and an outer coating layer OC.

[0209] The second light-blocking layer BM2 may be disposed on the color filter layer CFL. The second light-blocking layer BM2 may include a light-blocking material such as a black matrix material. The materials of the first light-blocking layer BM1 and the second light-blocking layer BM2 may be the same or different.

[0210] The second light-blocking layer BM2 may not be disposed in the first pixel PX1, but may be disposed only in the second pixel PX2. The second light-blocking layer BM2 may be disposed in the non-emitting region NEA of the second pixel PX2, and may surround the emitting region EA of the second pixel PX2 in a planar view. In one embodiment, the second light-blocking layer BM2 may have a width smaller than that of the first light-blocking layer BM1, but is not limited thereto. The size, shape, and / or position of the second light-blocking layer BM2 may be adjusted or changed according to the target viewing angle range of the second pixel PX2.

[0211] The outer coating OC can be applied to the second light-blocking layer BM2. The outer coating OC can cover the color filter layer CFL and the second light-blocking layer BM2.

[0212] In the display device 10 according to the embodiment, the color filter transmission lengths of the light emitted from the light-emitting element ED in each emission region EA in the front direction (e.g., third-direction DR3) (hereinafter referred to as front light) and the light emitted in the side direction (hereinafter referred to as side light) can be different as they travel through each color filter CF. For example, the color filter transmission lengths L1 and L3 of the first front light Lf1 emitted from the second light-emitting element ED2 of the first pixel PX1 in the third-direction DR3 and the second front light Lf2 emitted from the second light-emitting element ED2 of the second pixel PX2 in the third-direction DR3 can correspond to the second thickness d2 of the second color filter CF2. On the other hand, the color filter transmission lengths L2 and L4 of the first side light Ls1 emitted from the second light-emitting element ED2 of the first pixel PX1 and the second side light Ls2 emitted from the second light-emitting element ED2 of the second pixel PX2 through the second color filter CF2 can be greater than the second thickness d2 of the second color filter CF2. The filter transmission length of the side light emitted from the corresponding light-emitting element (ED) can be varied depending on the thickness of each filter CF and the travel angle of the side light.

[0213] A portion of the sidelight emitted from each emission region EA of the second pixel PX2 and transmitted through the color filter layer CFL can be as follows: Figure 10 The light travels towards the second light-blocking layer BM2, as indicated by the dashed arrow, and is then blocked by the second light-blocking layer BM2. Therefore, the side light emission of the second pixel PX2 can be reduced. For example, the side light emission ratio of the second pixel PX2 can be lower than that of the first pixel PX1.

[0214] Furthermore, even within each pixel PX, the light emission ratio of the side light emitted from the corresponding light-emitting element ED can vary depending on the size or ratio of the emission region EA. For example, the size of the second emission region EA2 may be smaller than the size of each of the first emission region EA1 and the third emission region EA3, such that the light emission ratio of the second color side light may be lower than that of the first color side light and the third color side light. Therefore, when viewing an image displayed in the display region DA from the side, color shift may occur. For example, the lower side light emission ratio of the second color light compared to the first and third color light can cause viewing angle shift, and the side colors of the image may change.

[0215] Furthermore, since the side light emission ratios of the first pixel PX1 and the second pixel PX2 are different, the side colors of the first pixel PX1 and the second pixel PX2 can also be different. For example, the viewing angle shift of light emitted from the first pixel PX1 can be different from the viewing angle shift of light emitted from the second pixel PX2. For example, the reduction rate of side light emitted from the second light-emitting element ED2 of the second pixel PX2 can be greater than the reduction rate of side light emitted from the second light-emitting element ED2 of the first pixel PX1. Therefore, in the first emission mode in which both the first pixel PX1 and the second pixel PX2 are driven, when viewing an image displayed in the display area DA from the side, stains on the pixel units may be visually identifiable.

[0216] Furthermore, even in the first emission mode, which provides a wider viewing angle, the overall side brightness of the image displayed in the display area DA can be reduced due to the low side brightness of the second pixel PX2. The side light blocking rate or viewing angle of the second pixel PX2 can be appropriately adjusted or changed by taking into account both the side brightness in the first emission mode and the side light blocking rate in the second emission mode.

[0217] Figure 11 This is a cross-sectional view showing a display device according to one embodiment. Figure 12 This is a cross-sectional view showing a display device according to one embodiment. For example, Figure 11 and Figure 12 (It shows the relationship with along) Figures 4 to 8(A different embodiment of the display device 10 corresponding to a cross-section of the first pixel PX1 intercepted by line X1-X1' is shown, relating to the color filter layer CFL.) Figure 9 Different implementation methods.

[0218] In describing the following embodiments, components that are substantially the same as or similar to those in at least one of the above embodiments are denoted by the same reference numerals, and redundant descriptions will be omitted. Furthermore, each embodiment may be applied alone or in combination with at least one other embodiment, and all possible combinations of embodiments fall within the scope of this disclosure.

[0219] Reference Figure 11 and Figure 12 According to one embodiment, the display device 10 may further include a first pattern PTN1 (also referred to as a "first light control layer" or "first contour control layer") disposed in the color filter layer CFL. The first pattern PTN1 may be disposed in a first pixel region where each first pixel PX1 is disposed, and may be disposed in at least one emission region EA among the emission regions EA of the first pixel PX1. In each emission region EA where the first pattern PTN1 is disposed, the first pattern PTN1 may be disposed below the color filter CF. In one embodiment, the first pattern PTN1 may be formed as an isolation pattern disposed in each emission region EA and may be spaced apart from the first light-blocking layer BM1. In a plan view, the first pattern PTN1 may be surrounded by the first light-blocking layer BM1.

[0220] The first pattern PTN1 can be a light-transmitting pattern. For example, the first pattern PTN1 can be substantially transparent and therefore can have light-transmitting properties. Thus, light emitted from each light-emitting element ED can be transmitted through the first pattern PTN1. The first pattern PTN1 can be formed from organic or inorganic materials, and there are no particular limitations on the material of the first pattern PTN1.

[0221] In one embodiment, a first pattern PTN1 may be disposed on and cover the light-emitting element ED disposed in each emission region EA. For example, in the emission region EA where the first pattern PTN1 is disposed, the first pattern PTN1 may partially or completely cover the opening OPN of the pixel defining film PDL. Therefore, in the emission region EA where the first pattern PTN1 is disposed, front light emitted from the light-emitting element ED (e.g., first front light Lf1) can be transmitted through the first pattern PTN1 and a portion of the color filter CF disposed on the first pattern PTN1. Furthermore, in the emission region EA where the first pattern PTN1 is disposed, at least a portion of the side light emitted from the light-emitting element ED (e.g., first side light Ls1) can be transmitted through the first pattern PTN1 and a portion of the color filter CF disposed on the first pattern PTN1.

[0222] The color filter CF disposed on the first pattern PTN1 may have a surface profile similar to that of the first pattern PTN1. For example, the color filter CF disposed on the first pattern PTN1 may protrude in the height direction (e.g., the third direction DR3) due to the first pattern PTN1, and thus may have a substantially convex profile shape. For example, the color filter CF disposed on the first pattern PTN1 may include a central portion and an edge portion, the central portion being disposed on the first pattern PTN1 in each emission region EA and protruding upwards from the periphery to have a convex shape, the edge portion surrounding the central portion and having a height lower than that of the central portion. The edge portion may extend into the non-emission region NEA and may overlap with the first light-blocking layer BM1 in the non-emission region NEA.

[0223] In one embodiment, the central portion of the color filter CF may have a thickness determined according to the light emission efficiency of the light-emitting element ED or the like, regardless of whether the first pattern PTN1 is provided. For example, the central portions of the first color filter CF1, the second color filter CF2, and the third color filter CF3 of the first pixel PX1 may have a first thickness d1, a second thickness d2, and a third thickness d3, respectively.

[0224] In one implementation, the first pattern PTN1 may be set in all emission regions EA of the first pixel PX1. For example, as Figure 11 As shown, the first pattern PTN1 can be set in each of the first emission region EA1, the second emission region EA2, and the third emission region EA3 of the first pixel PX1.

[0225] The first color filter CF1, second color filter CF2, and third color filter CF3 of the first pixel PX1 arranged on each first pattern PTN1 may protrude in the height direction due to each first pattern PTN1. Therefore, the first color filter CF1, second color filter CF2, and third color filter CF3 of the first pixel PX1 may have a substantially convex shape in the central portion located in each emission region EA. For example, each of the first color filter CF1, second color filter CF2, and third color filter CF3 of the first pixel PX1 may have a central portion disposed on each first pattern PTN1 and protruding in the height direction, and an edge portion surrounding the central portion and having a height lower than that of the central portion.

[0226] Because the central portion of each of the first color filters CF1, CF2, and CF3 of the first pixel PX1 protrudes in the height direction due to the first pattern PTN1, the side light emitted from the first emission region EA1, second emission region EA2, and third emission region EA3 of the first pixel PX1 can be increased. For example, compared to a pixel excluding the first pattern PTN1... Figure 9 Compared to the first pixel PX1, in Figure 11 In the first pixel PX1, the color filter transmission length (e.g., the color filter transmission length L2' of the first side light Ls1) of at least a portion of the side light (e.g., the first side light Ls1) can be reduced or minimized. Therefore, the amount of side light emitted from the first pixel PX1 is increased, thereby improving the side brightness of the first pixel PX1.

[0227] In another embodiment, the first pattern PTN1 may be disposed only in some emission regions EA within the emission region EA of the first pixel PX1. For example, the first pattern PTN1 may be disposed only in the emission region EA of the first pixel PX1 that emits light of a specific color (e.g., light of a first color, a second color, or a third color), and may not be disposed in other emission regions EA. For example, as Figure 12 As shown, the first pattern PTN1 may be set only in the second emission region EA2 of the first pixel PX1, and may not be set in the first emission region EA1 and the third emission region EA3 of the first pixel PX1. Alternatively, the first pattern PTN1 may be set in multiple emission regions EA that emit light of different colors, and may not be set in other emission regions EA.

[0228] A color filter CF disposed in an emission region EA of the first pixel PX1 that does not have a first pattern PTN1 may have an overall concave shape. For example, a color filter CF disposed in an emission region EA that does not have a first pattern PTN1 may include a central portion disposed in each emission region EA, and an edge portion surrounding the central portion and having a height higher than the height of the central portion.

[0229] In one embodiment, at least one emission region EA that has a significant impact on the side brightness or side color of the first pixel PX1 can be selected. The first pattern PTN1 can be disposed only in the at least one emission region EA, and the first pattern PTN1 may not be disposed in other emission regions EA of the first pixel PX1. For example, depending on the color of the light emitted from the respective emission region EA or the size of the emission region EA, the first pattern PTN1 can be selectively disposed only in some emission regions EA that include the at least one emission region EA that has a significant impact on the side brightness or side color. In terms of emitted color, when the first color light, second color light, and third color light emitted from the first emission region EA1, the second emission region EA2, and the third emission region EA3 of the first pixel PX1 are red light, green light, and blue light, respectively, the first pattern PTN1 can be disposed at least in the second emission region EA2 of the first pixel PX1. In terms of the light-emitting area, when the size of the second emission region EA2 among the first emission regions EA1, the second emission region EA2, and the third emission region EA3 of the first pixel PX1 is the smallest, the first pattern PTN1 can be disposed at least in the second emission region EA2 of the first pixel PX1. Therefore, the filter transmission length L2' of the first side light Ls1 of the second color emitted from the first pixel PX1 can be reduced, thereby increasing the brightness of the first side light Ls1 of the second color.

[0230] At least one other color filter CF disposed in the emission region EA where the first pattern PTN1 is not disposed may include a central portion disposed in each emission region EA, and an edge portion surrounding the central portion and having a height higher than the central portion. For example, the first pattern PTN1 may not be disposed in the first emission region EA1 and the third emission region EA3 of the first pixel PX1. Therefore, the first color filter CF1 and the third color filter CF3 of the first pixel PX1 may have the same height as the first emission region EA1 and the third emission region EA3 of the first pixel PX1. Figure 9 The shapes in the embodiments are substantially the same or similar, and the brightness of the first color sidelight and the third color sidelight of the first pixel PX1 can be compared with... Figure 9 Those implementations are substantially the same or similar.

[0231] By increasing the side light of a specific color emitted from the first pixel PX1 (e.g., the first side light Ls1 of the second color), the side color of the first pixel PX1 can be adjusted (or corrected) or improved. For example, as Figure 9 In the case where the side light reduction rate of the first pixel PX1 without the first pattern PTN1 is the highest among the first side light Ls1 of the second color, the side color of the first pixel PX1 is more biased towards the first color or the third color, and may become more reddish or more bluish. On the other hand, as Figure 11In the process, when the first pattern PTN1 is set in the second emission area EA2 of the first pixel PX1, the green first side light Ls1 emitted from the second emission area EA2 of the first pixel PX1 increases, so that the side brightness and side color of the first pixel PX1 can be adjusted or improved.

[0232] However, the implementation is not limited to adjusting the side color of the first pixel PX1 by increasing the first side light Ls1 of the second color emitted from the first pixel PX1. For example, in another implementation, the side color of the first pixel PX1 can be adjusted or improved in a desired manner by setting a first pattern PTN1 in at least one of the first emission region EA1 and the third emission region EA3 to increase at least one of the side light of the first color and the side light of the third color.

[0233] according to Figure 11 and Figure 12 In one implementation, the brightness of the display device 10 in the first emission mode can be improved by forming a first pattern PTN1 in each of the emission regions EA. In some implementations, the side brightness and / or side color of the first pixel PX1 can be appropriately adjusted or improved by selectively setting the first pattern PTN1 only in at least one of the emission regions EA of the first pixel PX1.

[0234] Figure 13 This is a cross-sectional view showing a display device according to one embodiment. Figure 14 This is a cross-sectional view showing a display device according to one embodiment. For example, Figure 13 and Figure 14 (It shows the relationship with along) Figures 4 to 8 (A different embodiment of the display device 10 corresponding to the cross-section of the second pixel PX2 intercepted by line X2-X2' is shown, relating to the color filter layer CFL.) Figure 10 Different implementation methods.

[0235] Reference Figure 13 and Figure 14 According to one embodiment, the display device 10 may further include a second pattern PTN2 (also referred to as a "second light control layer" or "second contour control layer") disposed in the color filter layer CFL. The second pattern PTN2 may be disposed in the second pixel region where each second pixel PX2 is disposed, and may be disposed in the non-emissive region NEA of the second pixel PX2. For example, the second pattern PTN2 may be disposed in the non-emissive region NEA around the emission region EA of the second pixel PX2, below at least one of the color filters CF disposed in the emission region EA of the second pixel PX2.

[0236] The second pattern PTN2 may overlap with the first light-blocking layer BM1 in the non-emitting region NEA of the second pixel PX2. In one embodiment, the second pattern PTN2 may be disposed below the first light-blocking layer BM1 and may have a width larger than the width of the first light-blocking layer BM1. However, the embodiment is not limited thereto. For example, at least one of the relative positions and dimensions of the first light-blocking layer BM1 and the second pattern PTN2 may be changed.

[0237] The second pattern PTN2 may or may not have light-transmitting properties. For example, the second pattern PTN2 may be a light-transmitting pattern formed synchronously with the first pattern PTN1 using the same material as the first pattern PTN1, and may be substantially transparent. Alternatively, the second pattern PTN2 may be formed as an opaque light-blocking pattern different from the first pattern PTN1. When the second pattern PTN2 has light-blocking properties, it can more effectively reduce or block side light from the second pixel PX2. The second pattern PTN2 may be formed from organic or inorganic materials, and there are no particular limitations on the material of the second pattern PTN2.

[0238] The color filter CF of the second pixel PX2 may have a lower height at the central portion disposed in the corresponding emitting region EA, and a higher height by means of a pattern disposed below it in the non-emitting region NEA surrounding the emitting region EA. For example, the edge portion of each of the color filters CF of the second pixel PX2 may be disposed at least on the first light-blocking layer BM1 in the non-emitting region NEA, and thus may protrude upwards more than the central portion disposed in the emitting region EA. For example, each of the color filters CF of the second pixel PX2 may have a concave shape with a lower height in the emitting region EA. In one embodiment, each of the color filters CF of the second pixel PX2 may have a thickness set according to the light emission efficiency of the light-emitting element ED or the like, regardless of whether the second pattern PTN2 is disposed at the central portion disposed in the emitting region EA. For example, the central portions of the first color filter CF1, the second color filter CF2, and the third color filter CF3 of the second pixel PX2 may have a first thickness d1, a second thickness d2, and a third thickness d3, respectively. Therefore, the front light emission ratio of the pixel PX can be generally uniform. For example, the front light emission ratios of the first pixel PX1 and the second pixel PX2 can be substantially the same or similar.

[0239] In one implementation, the second pattern PTN2 may be entirely disposed within the non-emitting region NEA of the second pixel PX2. For example, as Figure 13 As shown, the second pattern PTN2 can be completely set in the non-emission area NEA of the second pixel PX2 to surround the first emission area EA1, the second emission area EA2 and the third emission area EA3 of the second pixel PX2.

[0240] In another embodiment, the second pattern PTN2 may be partially disposed within the non-emitting region NEA of the second pixel PX2, and may only surround some of the emitting regions EA within the emitting regions EA of the second pixel PX2. For example, the second pattern PTN2 may be disposed only around the emitting regions EA of the second pixel PX2 that emit light of a specific color (e.g., a first color light, a second color light, or a third color light). For example, as... Figure 14 As shown, the second pattern PTN2 may be partially disposed in the non-emitting region NEA of the second pixel PX2, and may selectively surround only the second emitting region EA2 of the second pixel PX2. Alternatively, the second pattern PTN2 may surround multiple emitting regions EA of the second pixel PX2 that emit light of different colors, and may not surround other emitting regions EA.

[0241] In one implementation, the second pattern PTN2 may be disposed only in a portion of the second pixel region where the second pixel PX2 is disposed. For example, the second pattern PTN2 may be disposed partially or entirely in the non-emitting region NEA of the second pixel PX2, and may not be disposed in the emitting region EA of the second pixel PX2.

[0242] In the color filter CF of the second pixel PX2, at least one color filter CF disposed on the second pattern PTN2 may have a surface profile similar to the surface profile of the second pattern PTN2. For example, at least one color filter CF disposed on the second pattern PTN2 may protrude to a higher height at the edge portion through the second pattern PTN2. Therefore, the stepped portion between the center portion and the edge portion of the color filter CF disposed on the second pattern PTN2 may be increased due to the second pattern PTN2.

[0243] Because the step portion between the center and edge portions of at least one of the color filters CF of the second pixel PX2 is added by the second pattern PTN2, the side light emitted from the emission region EA surrounded by the second pattern PTN2 can be reduced. For example, compared with excluding Figure 13 and Figure 14 The second pattern PTN2 in the second pixel PX2 Figure 10 Compared to the second pixel PX2, the color filter transmission length (e.g., the color filter transmission length L4' of at least a portion of the side light (e.g., the second side light Ls2) can be increased or maximized. Therefore, the amount of side light emitted from the second pixel PX2 can be reduced, thereby more effectively limiting the light emission angle, side brightness, or side viewing angle of the second pixel PX2.

[0244] In one embodiment, at least one emission region EA that has a significant impact on the side brightness or side color of the second pixel PX2 can be selected, and the second pattern PTN2 can be selectively disposed only around the at least one emission region EA. For example, depending on the color of the light emitted from the respective emission region EA or the size of the emission region EA, the second pattern PTN2 can be selectively disposed only around some emission regions EA that include the at least one emission region EA that has a significant impact on the side brightness or side color. In terms of emission color, when the first color light, second color light, and third color light emitted from the first emission region EA1, second emission region EA2, and third emission region EA3 of the second pixel PX2 are red light, green light, and blue light, respectively, the second pattern PTN2 can be disposed at least around the second emission region EA2 of the second pixel PX2. In terms of the light-emitting area, when the size of the second emission region EA2 among the first emission region EA1, second emission region EA2, and third emission region EA3 of the second pixel PX2 is the smallest, the second pattern PTN2 can be disposed at least around the second emission region EA2 of the second pixel PX2. Therefore, the filter transmission length L4' of the second side light Ls2 of the second color emitted from the second pixel PX2 can be increased, thereby reducing the brightness of the second side light Ls2 of the second color.

[0245] The amount of sidelight emitted by the emission region EA, which is never surrounded by the second pattern PTN2, may not be significantly changed by the second pattern PTN2. For example, when the second pattern PTN2 is only partially disposed around the second emission region EA2 of the second pixel PX2, the brightness of the first color sidelight and the third color sidelight of the second pixel PX2 may be comparable to... Figure 10 Those implementations are substantially the same or similar.

[0246] By reducing the sidelight of a specific color emitted from the second pixel PX2 (e.g., the second sidelight Ls2 of the second color), the side brightness and / or side color of the second pixel PX2 can be adjusted (or corrected) or improved. For example, by reducing or minimizing the second sidelight Ls2 of green, which has the greatest impact on the side brightness and / or side color of the second pixel PX2, the side light blocking rate of the second pixel PX2 can be further increased, and the viewing angle limiting effect can be enhanced in the second emission mode in which the side viewing angle is limited.

[0247] In one implementation, the second pattern PTN2 may be disposed only around some emission regions EA within the emission regions EA of the second pixel PX2 to reduce or minimize the lateral color difference between the first pixel PX1 and the second pixel PX2. For example, in a first emission mode in which both the first pixel PX1 and the second pixel PX2 are driven, the second pattern PTN2 may be partially disposed in the non-emission regions NEA of each of the second pixels PX2 to reduce the lateral color difference between the first pixel PX1 and the second pixel PX2. For example, in Figure 14 In this configuration, the second pattern PTN2 is only located within the non-emitting region NEA of the second pixel PX2, surrounding the second emitting region EA2, but the position or size of the second pattern PTN2 can be changed. By reducing or minimizing the lateral color difference between the first pixel PX1 and the second pixel PX2, it is possible to prevent visually identifiable stains on the pixel units in the first emitting mode.

[0248] according to Figure 13 and Figure 14 In this implementation, sidelight emitted from the second pixel PX2 can be more effectively reduced or blocked by the second pattern PTN2. Therefore, the viewing angle limiting effect in the second emission mode can be enhanced.

[0249] In some embodiments, by selectively providing the second pattern PTN2 only around at least one emission region EA in the emission region EA of the second pixel PX2, the side brightness and / or side color of the second pixel PX2 can be appropriately adjusted or improved. For example, the side brightness and / or side color of the second pixel PX2 can be adjusted to reduce or minimize the side color difference between the first pixel PX1 and the second pixel PX2. Therefore, the image quality of the display device 10 can be improved.

[0250] Figure 15 This is a cross-sectional view showing a display device according to one embodiment. Figure 16 This is a cross-sectional view showing a display device according to one embodiment. For example, Figure 15 and Figure 16 (It shows the relationship with along) Figures 4 to 8 (A different embodiment of the display device 10 corresponding to the cross-section of the second pixel PX2 intercepted by line X2-X2' is shown, relating to the first light-blocking layer BM1 and the second pattern PTN2.) Figure 13 and Figure 14 Different implementation methods.

[0251] Reference Figure 15 and Figure 16The first light-blocking layer BM1 and the second pattern PTN2 can be integrally formed. For example, the first light-blocking layer BM1 and the second pattern PTN2 can be formed by a single mask process using a halftone mask. In this case, the second pattern PTN2 may include a light-blocking material and can be considered as part of the first light-blocking layer BM1. For example, by forming an upwardly projecting first light-blocking layer BM1 at a location where the height of the color filter CF needs to be increased, the first light-blocking layer BM1 can be used as the second pattern PTN2. Since the first light-blocking layer BM1 and the second pattern PTN2 are formed synchronously and / or integrally, the manufacturing process of the display device 10 can be simplified.

[0252] Figure 17 This is a cross-sectional view showing a display device according to one embodiment. For example, Figure 17 (showing the relationship with along) Figures 4 to 8 The section of the first pixel PX1 cut by line X1-X1' (corresponding to a portion of the display device 10) shows the relationship between the first pattern PTN1 and... Figure 11 and Figure 12 Different implementation methods.

[0253] Figure 18 This is a cross-sectional view showing a display device according to one embodiment. For example, Figure 18 (It shows the relationship with along) Figures 4 to 8 The section of the second pixel PX2 intercepted by line X2-X2' (corresponding to a portion of the display device 10) shows the relationship between the second pattern PTN2 and... Figures 13 to 16 Different implementation methods.

[0254] Reference Figure 17 and Figure 18 The display device 10 may further include an insulating layer INS covering the touch electrodes TL, and the first pattern PTN1 and the second pattern PTN2 may be integrally formed with the insulating layer INS. In one embodiment, the insulating layer INS may be entirely formed in the display area DA. For example, the insulating layer INS may completely cover the touch sensing layer TSU including the touch electrodes TL.

[0255] The insulating layer INS can be light-transmitting. For example, the insulating layer INS can be substantially transparent. Therefore, light emitted from the light-emitting element ED can be transmitted through the insulating layer INS.

[0256] The insulating layer INS may partially protrude upward from at least one of the emission regions EA of the first pixel PX1. For example, the top surface of the insulating layer INS in the first pixel region may have a stepped portion. Therefore, the insulating layer INS may form each first pattern PTN1 at a position corresponding to at least one emission region EA. Thus, the side brightness and / or side color of the first pixel PX1 can be improved.

[0257] In one embodiment, the insulating layer INS may be entirely disposed in the second pixel region including the emitting region EA of the second pixel PX2 and the non-emitting region NEA surrounding the emitting region EA. In one embodiment, the insulating layer INS may have a substantially uniform thickness in the emitting region EA and the non-emitting region NEA of the second pixel PX2, and the top surface of the insulating layer INS may be substantially flat in the second pixel region. Therefore, in the second pixel region, regardless of whether the second pattern PTN2 is provided, the color filter CF may have a shape according to the first light-blocking layer BM1 or the like, and the side brightness or side color of the second pixel PX2 may remain substantially unchanged. However, the embodiments are not limited to this. For example, in another embodiment, the thickness of the insulating layer INS may be differentiated for each portion of the second pixel region. For example, the thickness of the insulating layer INS may be differentiated for each portion such that the thickness of the insulating layer INS is partially increased around at least one emitting region EA in the emitting regions EA of the second pixel PX2, or the thickness of the insulating layer INS is partially decreased in at least one emitting region EA to reduce side light emitted from at least one emitting region EA. Therefore, the side brightness and / or side color of the second pixel PX2 can be adjusted or optimized.

[0258] Figure 19 This is a cross-sectional view showing a display device according to one embodiment. For example, Figure 19 (It shows the relationship with along) Figures 4 to 8 The section of the first pixel PX1 cut by line X1-X1' (corresponding to a portion of the display device 10) shows the relationship between the first pattern PTN1 and... Figure 11 , Figure 12 and Figure 17 Different implementation methods.

[0259] Figure 20 This is a cross-sectional view showing a display device according to one embodiment. For example, Figure 20 (It shows the relationship with along) Figures 4 to 8 The section of the second pixel PX2 intercepted by line X2-X2' (corresponding to a portion of the display device 10) shows the relationship between the second pattern PTN2 and... Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 18 Different implementation methods.

[0260] Reference Figure 19 and Figure 20The first pattern PTN1 and the second pattern PTN2 can be arranged between the light-emitting element layer EML and the color filter layer CFL. For example, the first pattern PTN1 and the second pattern PTN2 can be arranged in the touch sensing layer TSU.

[0261] In one embodiment, the first pattern PTN1 and the second pattern PTN2 may be integrally formed with an insulating layer disposed beneath the touch electrode TL. For example, the first pattern PTN1 and the second pattern PTN2 may be integrally formed with the second insulating layer SIL2 of the touch sensing layer TSU.

[0262] In one embodiment, the second insulating layer SIL2 may partially protrude within at least one of the emission regions EA of the first pixel PX1. Therefore, the second insulating layer SIL2 may form each first pattern PTN1 at a location corresponding to at least one emission region EA. This improves the side brightness and / or side color of the first pixel PX1.

[0263] In one embodiment, the second insulating layer SIL2 may have partially different thicknesses and / or heights in the second pixel region. For example, the second insulating layer SIL2 may have a relatively large thickness and protrude upwards in the non-emitting region NEA surrounding at least one emitting region EA of the second pixel PX2, and may have a relatively small thickness and a downwardly recessed shape in the emitting region EA of the second pixel PX2. Therefore, the color filter transmission length of the sidelight emitted from at least one emitting region EA of the second pixel PX2 can be increased, thereby reducing the sidelight emitted from at least one emitting region EA. Therefore, the side brightness and / or side color of the second pixel PX2 can be adjusted or optimized by the second pattern PTN2.

[0264] However, the implementation is not limited to this. For example, in another implementation, the second insulating layer SIL2 may have a uniform thickness throughout the second pixel region. Therefore, in the second pixel region, regardless of whether the second pattern PTN2 is provided, the color filter CF may have a shape according to the first light-blocking layer BM1 or the like, and the side brightness or side color of the second pixel PX2 may remain substantially unchanged.

[0265] As described above, according to the embodiment, by utilizing first pixels PX1 and second pixels PX2 with different light emission angles or viewing angles, the viewing angle of the display device 10 can be changed according to the emission mode selected by the user. For example, by selectively arranging a first light-blocking layer BM1 and a second light-blocking layer BM2 in the first pixels PX1 and second pixels PX2 arranged in the display area DA, the light emission angle or side viewing angle of the first pixels PX1 and second pixels PX2 can be distinguished or optimized, and the first pixels PX1 and second pixels PX2 can be selectively driven according to the selected emission mode. Therefore, the side viewing angle of the image displayed in the display area DA can be appropriately and / or easily changed in response to the emission mode selected by the user.

[0266] Furthermore, according to the embodiments, by utilizing at least one of the first pattern PTN1 and the second pattern PTN2, the side light emission ratio of the first pixel PX1 and the second pixel PX2 can be further distinguished or optimized, and the side brightness and / or side color of the display device 10 can be improved. For example, by disposing the first pattern PTN1 below at least one color filter CF arranged in the emission region EA of the first pixel PX1, the at least one color filter CF can be formed to have a shape that protrudes at least in the height direction in the emission region EA. For example, at least one of the color filters CF of the first pixel PX1 can have a convex cross-sectional shape. Therefore, the side light emission ratio of the first pixel PX1 can be increased, and the brightness and viewing angle of the first pixel PX1 can be improved.

[0267] In some embodiments, the first pattern PTN1 may be selectively disposed only in some emission regions EA of the first pixel PX1 to prevent or reduce viewing angle shift. Therefore, in a first emission mode in which the first pixel PX1 is driven and provides a wider viewing angle, viewing angle shift can be prevented or reduced, and the side color of the display device 10 can be adjusted or improved.

[0268] Furthermore, according to some embodiments, by setting the second pattern PTN2 below the edge of at least one color filter CF arranged in the emission region EA of the second pixel PX2, the at least one color filter CF can be formed to have a shape that is more prominent in the height direction in the non-emission region NEA surrounding the emission region EA. For example, the second pattern PTN2 can be partially or entirely set in the non-emission region NEA of each of the second pixels PX2. Therefore, at least one of the color filter CFs of each of the second pixels PX2 can have a concave cross-sectional shape in which the stepped portion between the central portion and the edge portion is further increased. Therefore, in the second emission mode in which the side light of the second pixel PX2 is reduced or blocked, the side viewing angle can be more effectively limited, and the viewing angle is limited by displaying the image only by the second pixel PX2.

[0269] In some embodiments, the second pattern PTN2 may be selectively arranged only in the non-emitting regions NEA surrounding some of the emitting regions EA of the second pixel PX2 to prevent or reduce viewing angle shift. In some embodiments, by utilizing at least one of the first pattern PTN1 and the second pattern PTN2 to control the side lighting of the first pixel PX1 and the second pixel PX2, the side color difference between the first pixel PX1 and the second pixel PX2 can be reduced or prevented. For example, when the side color of the second pixel PX2 becomes redder compared to the side color of the first pixel PX1, the proportion of red light in the side lighting emitted from the second pixel PX2 can be reduced by forming the first color filter CF1 of the second pixel PX2 into a concave shape in which the step portion between the central portion and the edge portion is further increased. Furthermore, by forming the first color filter CF1 of the first pixel PX1 into a convex shape using the first pattern PTN1 and / or forming or maintaining the second color filter CF2 of the first pixel PX1 into a concave shape, the proportion of red light in the side lighting emitted from the first pixel PX1 can be increased. Alternatively, the side color of the second pixel PX2 can be adjusted only by the second pattern PTN2 without changing the side color of the first pixel PX1, or the side color of the first pixel PX1 can be adjusted only by the first pattern PTN1 without changing the side color of the second pixel PX2. Therefore, the side color difference between the first pixel PX1 and the second pixel PX2 can be reduced or minimized, and the image quality of the display device 10 can be improved.

[0270] According to the embodiments, the first pattern PTN1 and the second pattern PTN2 can be applied independently to the first pixel PX1 and the second pixel PX2, and all possible combinations of the embodiments fall within the scope of this disclosure. For example, each embodiment can be applied to the display device 10 alone, or at least two embodiments according to possible combinations can be applied together to the display device 10. For example, a display device 10 including the first pixel PX1 and the second pixel PX2 may include the first pattern PTN1 disposed in each of the first pixels PX1 and may not include the second pattern PTN2, may include the second pattern PTN2 disposed in each of the second pixels PX2 and may not include the first pattern PTN1, or may include both the first pattern PTN1 disposed in each of the first pixels PX1 and the second pattern PTN2 disposed in each of the second pixels PX2.

[0271] In concluding this detailed description, those skilled in the art will understand that many variations and modifications can be made to the embodiments without substantially departing from the principles of the inventive concept. Therefore, the disclosed embodiments of the inventive concept are used only in a general and descriptive sense and not for limiting purposes.
