[0059] This disclosure will now be described more fully below with reference to the accompanying drawings, in which one or more embodiments of the disclosure are illustrated. However, this disclosure may be embodied in different forms and should not be construed as limited to the one or more 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 this disclosure to those skilled in the art.

[0060] It will be understood that if a layer is referred to as "on" another layer or substrate (e.g., when a layer is referred to as "on" another layer or substrate), it can be directly on that other layer or substrate, or one or more intervening layers may be present. In contrast, "directly on" can mean that there is no additional intervening element or layer between the element or layer and another element or layer. Throughout this disclosure, the same or similar reference numerals indicate the same or similar parts, and therefore, for the sake of brevity, repeated descriptions thereof are not provided.

[0061] In the following description, embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings.

[0062] Figure 1 This is a perspective view illustrating a display device according to one or more embodiments of the present disclosure.

[0063] refer to Figure 1 The display device 10, which is a means of displaying moving or still images, can be used as a display screen for one or more suitable electronic devices (such as televisions, laptops, monitors, billboards and Internet of Things (IoT) devices) and portable electronic devices (such as mobile phones, smartphones, tablet PCs, smartwatches, watch phones, mobile communication terminals, e-notebooks, e-books, portable multimedia players (PMPs), navigation devices and / or ultra-mobile PCs (UMPCs)).

[0064] The display device 10 according to one or more embodiments may be an organic light-emitting display device including organic light-emitting diodes, a quantum dot light-emitting display device including a quantum dot light-emitting layer, an inorganic light-emitting display device including inorganic semiconductors, or a micro light-emitting display device using micron or nano light-emitting diodes (LEDs). Hereinafter, one or more embodiments in which the display device 10 is an organic light-emitting display device will be described, but the type (variety) of the display device 10 is not limited thereto.

[0065] In one or more embodiments, the display device 10 may be formed as a flat surface. For example, the display device 10 may be formed as substantially flat on a plane defined by a first direction DR1 and a second direction DR2, and may have a set or predetermined thickness (or height) on a third direction DR3. In one or more embodiments, the display device 10 may include curved surfaces in at least a portion thereof (including edge areas, etc.). In one or more embodiments, the display device 10 may be formed as flexible, such that it can be bent, folded, rolled, or rolled up.

[0066] In one or more embodiments, regarding the image display surface of the display device 10, the first direction DR1 can be a length direction, a column direction, or a vertical direction, and the second direction DR2 can be a direction intersecting the first direction DR1, such as a width direction, a row direction, or a horizontal direction. The third direction DR3 can be the thickness direction or the height direction of the display device 10.

[0067] The display device 10 may include a display panel 100, a driver 200, a circuit board 300, and a touch driver 400.

[0068] The display panel 100 may include a main area MA and a secondary area SBA. The main area MA includes a display area DA in which an image is displayed, and the secondary area SBA is located on one side (e.g., one side) of the main area MA.

[0069] The primary region MA may include a display area DA and a non-display area NA surrounding the display area DA (e.g., around the display area DA). The display area DA may be located at the center of the primary region MA and occupy most of the area of ​​the primary region MA. The non-display area NA may be located at the edge of the primary region MA and may be in contact with the secondary region SBA.

[0070] The display area DA may be an area in which pixels are arranged, and may be an area in which an image is displayed through pixels. In one or more embodiments, the display area DA may be further provided with a sensing pattern (e.g., a touch electrode) for detecting touch input, etc., and the display area DA may include a sensing area for detecting touch input through the sensing pattern.

[0071] In one or more embodiments, the display area DA may include a long side on a first direction DR1 and a short side on a second direction DR2, and may be formed as a plane with an approximately rectangular shape. The corner where the long side and the short side of the display area DA intersect may be rounded or right-angled. The shape of the display area DA may be varied according to one or more embodiments. For example, in one or more embodiments, the display area DA may be formed in a polygonal shape other than a quadrilateral shape, a circular shape, and / or an elliptical shape, etc.

[0072] The display area DA may include a main display area MDA and a sub-display area SDA. The sub-display area SDA may be an area in which components for adding one or more appropriate functions to the display device 10 are arranged, and the sub-display area SDA may correspond to the component area.

[0073] The non-display area NA may be located immediately adjacent to the display area DA. The non-display area NA may surround the display area DA (e.g., around the display area DA). Embedded circuitry may be arranged in the non-display area NA. For example, in one or more embodiments, embedded circuitry including scan driving circuitry may be arranged in the non-display area NA located on one side (e.g., the left or right side) or both sides (e.g., opposite edge sides) of the display area DA.

[0074] The secondary region SBA may be located on one side (e.g., one side) of the primary region MA. For example, in one or more embodiments, the secondary region SBA may be a region that protrudes in a first direction DR1 from one side of the primary region MA. For example, in one or more embodiments, the secondary region SBA may protrude in the first direction DR1 from the lower end of the primary region MA. In one or more embodiments, the secondary region SBA may have a narrower width than the primary region MA. For example, with respect to the second direction DR2, the secondary region SBA may have a narrower width than the primary region MA.

[0075] Wiring and pads can be arranged in the sub-region SBA. For example, wiring and pads can be arranged in the sub-region SBA to connect to pixels and / or embedded circuitry located in the main region MA and to drivers 200 and / or circuit boards 300 located in the sub-region SBA. In describing embodiments, the term "connection" can include electrical connections and / or physical connections.

[0076] In one or more embodiments, driver 200 (e.g., display driver circuitry) may be mounted in a sub-region SBA. Circuit board 300 may be arranged on a portion of the sub-region SBA.

[0077] The driver 200 may include data driving circuitry to drive pixels. In one or more embodiments, the driver 200 may be formed as an integrated circuit (IC) chip and disposed in a sub-area SBA. In one or more embodiments, the driver 200 may be disposed on a circuit board 300 on the sub-area SBA, or may be disposed on another circuit board connected to the display panel 100 via the circuit board 300.

[0078] The circuit board 300 may be disposed on a portion of the sub-region SBA. For example, in one or more embodiments, the circuit board 300 may be bonded to pads positioned on a portion (e.g., the lower edge) of the sub-region SBA and may supply or transmit power supply voltages and drive signals for driving the display panel 100 to the display panel 100. For example, the circuit board 300 may supply input image data (e.g., digital image data), drive signals including timing signals, and drive voltages to the display panel 100. The circuit board 300 may be a flexible printed circuit board (FPCB), a rigid printed circuit board (PCB), and / or a flexible film such as chip on film (COF), but embodiments of this disclosure are not limited thereto.

[0079] Touch driver 400 can be mounted on circuit board 300. Touch driver 400 can be connected to touch sensing unit of display panel 100. Touch driver 400 can supply touch driving signals to a plurality of touch electrodes of touch sensing unit and can sense the amount of change in capacitance between the plurality of touch electrodes. For example, in one or more embodiments, touch driving signals can be pulse signals with a set or predetermined frequency. Touch driver 400 can calculate whether an input has been made and the input coordinates based on the amount of change in capacitance between the plurality of touch electrodes. Touch driver 400 can be formed as an integrated circuit (IC).

[0080] Figure 2 This is a plan view illustrating a display device according to one or more embodiments of the present disclosure. Figure 3 According to one or more embodiments along Figure 2 A cross-sectional view of the display device taken by line X1-X1'.

[0081] Figure 1 The illustration shows the display device 10 unfolded without being bent, and Figure 2 and Figure 3 The figure shows the display device 10 bent in the sub-area SBA. Figure 1 This shows the state after the secondary region SBA and the primary region MA are expanded together, and Figure 2 and Figure 3 This shows the state of a portion of the sub-region SBA after it has been bent.

[0082] refer to Figure 2 and Figure 3 The display panel 100 may include a substrate SUB comprising a main region MA and a sub-region SBA, and a circuit layer (also referred to as a thin-film transistor layer) TFTL, a light-emitting element layer EML, a packaging layer TFEL, a touch-sensing layer TSU, and a color filter layer CFL arranged sequentially (e.g., in the order described) on the substrate SUB. The circuit layer TFTL may also be positioned within the main region MA and the sub-region SBA on the substrate SUB. The light-emitting element layer EML and the packaging layer TFEL may be positioned on a portion of the substrate SUB and the circuit layer TFTL. For example, the light-emitting element layer EML and the packaging layer TFEL may be positioned within the main region MA.

[0083] In one or more embodiments, the display device 10 may further include one or more additional elements disposed on the display panel 100. For example, in one or more embodiments, the display device 10 may further include at least one of a polarizing layer and a protective layer (e.g., a window) disposed on the encapsulation layer TFEL. Each of the polarizing layer and the protective layer may be integrally manufactured with the display panel 100, or may be manufactured separately from the display panel 100 and attached to the display panel 100 by an adhesive layer or the like.

[0084] The substrate SUB may include an insulating material such as a polymer resin. For example, in one or more embodiments, the substrate SUB may be made of polyimide or other insulating materials. The substrate SUB may be a flexible substrate that is deformable (such as bending, folding, or rolling). In one or more embodiments, the substrate SUB may include an insulating material such as glass.

[0085] A circuit layer TFTL may include pixel circuitry and wiring. For example, a circuit layer TFTL may include circuit elements (e.g., pixel transistors and capacitors) constituting the pixel circuitry of each pixel, as well as wiring connected to the pixels. In one or more embodiments, the circuit layer TFTL may further include circuit elements constituting embedded circuitry (such as scan drive circuitry), as well as wiring connected to the embedded circuitry.

[0086] The light-emitting element layer (EML) may include light-emitting elements disposed in the emitting regions of pixels. For example, each pixel may include at least one light-emitting element and pixel circuitry connected to the light-emitting element. Each pixel may be located in a pixel region comprising an emitting region where the light-emitting elements are disposed and a pixel circuitry region where the pixel circuitry is disposed. The emitting region and the pixel circuitry region of each pixel may overlap each other, but embodiments of this disclosure are not limited thereto.

[0087] In describing embodiments of this disclosure, the circuit layer TFTL and the light-emitting element layer EML are described separately, but the embodiments of this disclosure are not limited thereto. For example, in one or more embodiments, the circuit layer TFTL and the light-emitting element layer EML may be integrated.

[0088] The encapsulation layer TFEL may cover the light-emitting element layer EML and may extend into the non-display area NA to contact the circuit layer TFTL. In one or more embodiments, the encapsulation layer TFEL may have a multilayer structure comprising at least two inorganic encapsulation layers overlapping each other and at least one organic encapsulation layer interposed between the inorganic encapsulation layers.

[0089] The touch sensing layer (TSU) can be disposed on the encapsulation layer (TFEL). In one or more embodiments, the touch sensing layer (TSU) may include a plurality of touch electrodes for capacitively sensing a user's touch, and touch lines connecting the plurality of touch electrodes to the touch driver 400. For example, the touch sensing layer (TSU) may sense a user's touch using a mutual capacitance method or a self-capacitance method.

[0090] In one or more embodiments, the touch sensing layer TSU may be disposed on a separate substrate disposed on the display panel 100. In these embodiments, the substrate supporting the touch sensing layer TSU may be a base member encapsulating the display panel 100.

[0091] Multiple touch electrodes of the touch sensing layer TSU can be arranged in the touch sensor area overlapping with the display area DA. The touch lines of the touch sensing layer TSU can be arranged in the touch periphery area overlapping with the non-display area NA.

[0092] In one or more embodiments, the display device 10 may further include an optical device 500. The optical device 500 may be arranged in the sub-display area SDA. The optical device 500 may emit or receive light in the infrared, ultraviolet, and / or visible light bands. For example, in one or more embodiments, the optical device 500 may be an optical sensor, such as a proximity sensor, illuminance sensor, and / or camera sensor or image sensor, that detects light incident on the display device 10.

[0093] A color filter layer (CFL) can be disposed on the touch sensing layer (TSU). The CFL can include multiple color filters corresponding to multiple emission regions. Each color filter can selectively transmit light of a specific wavelength and can block or absorb light of different wavelengths. The CFL can absorb a portion of the light from outside the display device 10 to reduce reflected light caused by external light. Accordingly, the CFL can prevent or reduce color distortion caused by reflection of external light.

[0094] Because the color filter layer CFL is disposed directly on the touch sensing layer TSU, the display device 10 does not require a separate substrate for the color filter layer CFL. Consequently, the thickness of the display panel 100 can be relatively small.

[0095] In one or more embodiments, the display panel 100 may be bent in a bending region. The bending region may be part of a sub-region SBA and may be separated from and / or isolated from the main region MA (e.g., spaced apart or separated).

[0096] The substrate SUB and the circuit layer TFTL can be bent in the bending region corresponding to a portion of the sub-region SBA. Accordingly, the bezel area that is identified by the user as a non-display area NA can be reduced or minimized.

[0097] Figure 4 According to one or more embodiments of this disclosure Figure 2 A magnified view of region A. Figure 4 The arrangement of the sub-display area SDA in the display area DA of the display device 10 and the pixels MDX and SDX in the main display area MDA arranged around the sub-display area SDA is shown.

[0098] refer to Figure 4 The display area DA may include a main display area MDA and a sub-display area SDA. The sub-display area SDA may be an area where components are arranged below the substrate SUB of the display device 10. Multiple main display pixels (hereinafter referred to as main pixels) MDX may be arranged in the main display area MDA, and multiple sub-display pixels (hereinafter referred to as sub-pixels) SDX may be arranged in the sub-display area SDA. Each of the main display pixel MDX may include one or more main emitting areas MEA, and each of the sub-display pixel SDX may include one or more sub-emitting areas SEA. Light-emitting element ED (see...) Figure 11 It can be arranged in each of the emission areas MEA and SEA to emit light.

[0099] Multiple light-emitting elements (EDs) that emit light (see Figure 11 ) and electrically connected to the light-emitting element ED (see Figure 11 ) and apply to the light-emitting element ED (see Figure 11 The pixel circuitry for the emitted signals can be arranged in the main display area (MDA). The main display area (MDA) can be equipped with light-emitting elements (EDs) arranged in a specific configuration (see [link to relevant documentation]). Figure 11 The area includes the light-emitting elements (EDs) and pixel circuitry. In the main display area MDA, the light-emitting elements (EDs) are located within the main display area. Figure 11Each of the main emission regions (MEAs) can constitute a primary emission region (MEA), and multiple primary emission regions (MEAs) can constitute a primary display pixel (MDX). For example, in one or more embodiments, four primary emission regions (MEAs) can constitute a primary display pixel (MDX). For example, a primary display pixel (MDX) may include four primary emission regions (MEAs), and these four primary emission regions (MEAs) can constitute a primary display pixel (MDX) to represent white grayscale levels. The number of primary emission regions (MEAs) included in a primary display pixel (MDX) is not limited to this.

[0100] In one or more embodiments, the plurality of main display pixels (MDXs) arranged in the main display area (MDA) can be arranged on a fourth direction DR4 and a fifth direction DR5, which are diagonal directions between the first direction DR1 and the second direction DR2. Furthermore, the plurality of main emission areas (MEAs) of the main display pixels (MDXs) can be arranged on the fourth direction DR4 and the fifth direction DR5.

[0101] Light-emitting element ED (see Figure 11 The sub-display area (SDA) can also be arranged in the sub-display area (SEA) to form the sub-emission area (SEA), and multiple sub-emission areas (SEAs) can form a sub-display pixel (SDX). However, unlike the main display area (MDA), the sub-display area (SDA) can be an area that overlaps with components (e.g., optical devices 500) arranged on the rear surface of the substrate (SUB) of the display panel 100, and can have a structure in which light transmittance is taken into account.

[0102] A sub-display pixel SDX formed by multiple sub-emission areas SEA of a sub-display region SDA can have an arrangement different from that of the main display pixel MDX. For example, in one or more embodiments, the main display pixel MDX may include four main emission areas MEAs, while the sub-display pixel SDX may include seven sub-emission areas SEA. The four main emission areas MEAs of the main display pixel MDX may each correspond to four pixel circuits. In contrast, two or more sub-emission areas SEA of the sub-display pixel SDX may correspond to one pixel circuit. For example, in one or more embodiments, the sub-display pixel SDX may include seven sub-emission areas SEA that emit light through three pixel circuits. Accordingly, the brightness and resolution of the sub-display region SDA may differ from those of the main display region MDA.

[0103] In one or more embodiments, a plurality of sub-display pixels SDX arranged in the sub-display area SDA may be arranged on a fourth direction DR4 and a fifth direction DR5, which are diagonal directions between the first direction DR1 and the second direction DR2. Furthermore, a plurality of sub-emission areas SEA of the sub-display pixels SDX may be arranged on the fourth direction DR4 and the fifth direction DR5.

[0104] The sub-display area SDA may further include a transmissive region TA for transmitting light. The transmissive region TA is the area through which light incident on the display panel 100 passes.

[0105] The transmitting region TA can be arranged adjacent to the sub-emitting region SEA. The transmitting region TA may not overlap with the sub-emitting region SEA. The transmitting region TA may be surrounded by the sub-emitting region SEA.

[0106] Multiple transmission regions (TAs) can be arranged in the first direction DR1 and the second direction DR2. Sub-emission regions (SEAs) can be arranged not only in the first direction DR1 and the second direction DR2 between the multiple transmission regions TAs, but also in the fourth direction DR4 and the fifth direction DR5 between the multiple transmission regions TAs.

[0107] Because of the transmission region TA, the number of sub-emission regions SEA per unit area in the sub-display region SDA can differ from the number of primary emission regions MEA per unit area in the main display region MDA. For example, in one or more embodiments, the number of sub-emission regions SEA per unit area in the sub-display region SDA can be less than the number of primary emission regions MEA per unit area in the main display region MDA.

[0108] Furthermore, due to the transmission region TA, the ratio of the area of ​​the sub-emitting region SEA to the area of ​​the sub-display region SDA can be different from the ratio of the area of ​​the main emitting region MEA to the area of ​​the main display region MDA. For example, in one or more embodiments, the ratio of the area of ​​the sub-emitting region SEA to the area of ​​the sub-display region SDA can be less than the ratio of the area of ​​the main emitting region MEA to the area of ​​the main display region MDA.

[0109] In the following text, reference will be made to Figure 5 Let's describe the sub-display area SDA in more detail.

[0110] Figure 5 This is a plan view illustrating a sub-display area according to one or more embodiments of the present disclosure.

[0111] Apart from Figure 4 In addition, refer to Figure 5 The sub-display area SDA may include the central area CTA, the bridging area BRA, and the transmission area TA.

[0112] In one or more embodiments, the transmission region TA may include a first transmission region TA1, a second transmission region TA2, a third transmission region TA3, and a fourth transmission region TA4. The first transmission region TA1 and the third transmission region TA3 may be arranged in a first direction DR1, and the second transmission region TA2 and the fourth transmission region TA4 may be arranged in a second direction DR2. The first transmission region TA1 and the second transmission region TA2 may be arranged in a fifth direction DR5, and the first transmission region TA1 and the fourth transmission region TA4 may be arranged in a fourth direction DR4. The third transmission region TA3 and the second transmission region TA2 may be arranged in a fourth direction DR4, and the third transmission region TA3 and the fourth transmission region TA4 may be arranged in a fifth direction DR5. The first transmission region TA1, the second transmission region TA2, the third transmission region TA3, and the fourth transmission region TA4 may be arranged sequentially in a clockwise direction.

[0113] The central region CTA, which is the area surrounded by the first transmission region TA1, the second transmission region TA2, the third transmission region TA3, and the fourth transmission region TA4, can be positioned in the first direction DR1 between the first transmission region TA1 and the third transmission region TA3, and in the second direction DR2 between the second transmission region TA2 and the fourth transmission region TA4.

[0114] The bridging region BRA can be any region located between transmission regions TA, excluding the central region CTA. For example, the bridging region BRA could be a region located between transmission regions TA in the fourth direction DR4 and the fifth direction DR5.

[0115] The bridging region BRA may include a first bridging region BRA1, a second bridging region BRA2, a third bridging region BRA3, and a fourth bridging region BRA4. The first bridging region BRA1 may be positioned in the fifth direction DR5 between the first transmission region TA1 and the second transmission region TA2. The second bridging region BRA2 may be positioned in the fourth direction DR4 between the second transmission region TA2 and the third transmission region TA3. The third bridging region BRA3 may be positioned in the fifth direction DR5 between the third transmission region TA3 and the fourth transmission region TA4. The fourth bridging region BRA4 may be positioned in the fourth direction DR4 between the fourth transmission region TA4 and the first transmission region TA1. The first bridging region BRA1, the second bridging region BRA2, the third bridging region BRA3, and the fourth bridging region BRA4 may be arranged sequentially in a clockwise direction.

[0116] The first bridging region BRA1 and the second bridging region BRA2 can be arranged on the first direction DR1, the second bridging region BRA2 and the third bridging region BRA3 can be arranged on the second direction DR2, the third bridging region BRA3 and the fourth bridging region BRA4 can be arranged on the first direction DR1, and the fourth bridging region BRA4 and the first bridging region BRA1 can be arranged on the second direction DR2.

[0117] Sub-Emitting Area (SEA) can be located within the Central Transmission Area (CTA) and the Bridging Area (BRA). For example, as... Figure 5 As illustrated in the figures, in one or more embodiments, five sub-emission areas (SEAs) can be arranged in each central region (CTA) and one sub-emission area (SEA) can be arranged in each bridging region (BRA). However, the number of sub-emission areas (SEAs) arranged in the central region (CTA) and bridging region (BRA) is not limited to this.

[0118] In one or more embodiments, the sub-display pixel SDX may include a sub-emitting region SEA disposed in the central region CTA and a sub-emitting region SEA disposed in the bridging region BRA. For example, as Figure 4 and Figure 5 As illustrated in the figure, in one or more embodiments, the sub-display pixel SDX may include a sub-emission region SEA disposed in the central region CTA, the second bridging region BRA2, and the third bridging region BRA3.

[0119] In the display device 10 according to this embodiment, the sub-emission region SEA is arranged not only in the central region CTA but also in the bridging region BRA, thereby improving the resolution in the sub-display region SDA. Accordingly, the resolution difference between the main display region MDA and the sub-display region SDA can be minimized or reduced.

[0120] In the following description, the arrangement and structure of the pixels MDX in the main display area MDA and the pixels SDX in the sub-display area SDA of the display device 10 will be further described in more detail with reference to other accompanying drawings.

[0121] Figure 6 This illustrates one or more embodiments according to the present disclosure. Figure 4 The layout diagram of the light-blocking layer, the first color filter layer, the second color filter layer, and the third color filter layer in region B.

[0122] refer to Figures 6 to 10 The main display area (MDA) can include multiple main display pixels (MDXs). For example, the main display area (MDA) can include a first main display pixel (MDX1), a second main display pixel (MDX2), a third main display pixel (MDX3), and a fourth main display pixel (MDX4).

[0123] Multiple primary display pixels (MDXs) can be arranged on the fourth direction (DR4) and the fifth direction (DR5). For example, the first primary display pixel (MDX1) and the second primary display pixel (MDX2) can be arranged on the fifth direction (DR5), the second primary display pixel (MDX2) and the third primary display pixel (MDX3) can be arranged on the fourth direction (DR4), the third primary display pixel (MDX3) and the fourth primary display pixel (MDX4) can be arranged on the fifth direction (DR5), and the fourth primary display pixel (MDX4) and the first primary display pixel (MDX1) can be arranged on the fourth direction (DR4). The first primary display pixel (MDX1), the second primary display pixel (MDX2), the third primary display pixel (MDX3), and the fourth primary display pixel (MDX4) can cover the entire primary display area (MDA). Figure 6 The arrangement method is repeated.

[0124] Each of the plurality of main display pixel MDXs may include a plurality of main emitting regions MEA. For example, each of the plurality of main display pixel MDXs may include a first main emitting region MEA1, a second main emitting region MEA2, a third main emitting region MEA3, and a fourth main emitting region MEA4. However, the number of main emitting regions MEA included in a main display pixel MDX is not limited thereto and may be varied. In one or more embodiments, the first main emitting region MEA1, the second main emitting region MEA2, the third main emitting region MEA3, and the fourth main emitting region MEA4 may be arranged in the same manner in each of the plurality of main display pixel MDXs.

[0125] A primary display pixel (MDX) may include one or more light-emitting elements (EDs) (see...) Figure 11 One or more light-emitting elements (EDs) included in a main display pixel MDX (see...). Figure 11 ( ) can emit light of the same color or different colors. For example, in one or more embodiments, the light-emitting element ED (see Figure 11 It can emit a red first light, and the light-emitting element ED is arranged in the second main emission area MEA2 (see Figure 11It can emit a second green light, and the light-emitting element ED (see [reference]) is arranged in the third main emission area MEA3. Figure 11 It can emit a third blue light. The light-emitting element (ED) is arranged in the fourth main emission area MEA4 (see...). Figure 11 It can emit a second green light, but the embodiments disclosed herein are not limited thereto.

[0126] The main emission region MEA can be the emitting layer EL (see...) Figure 11 ) and their respective pixel electrodes AE1, AE2 and AE3 (see Figure 11 The overlapping areas. For example, pixel-defined film (PDL) (see...) Figure 11 The opening of the light-emitting element layer (EML) can correspond to the main emitting region (MEA). For example, the main emitting region (MEA) can be composed of the light-emitting element layer (EML) (see [link to relevant documentation]). Figure 11 Pixel-limited film PDL (see reference) Figure 11 It is defined by multiple openings.

[0127] The first main emission region MEA1 can be defined by a pixel-defined film PDL (see...). Figure 11 ) and the first pixel electrode AE1 (see Figure 11 The first opening overlaps to define the second main emission region MEA2, which can be defined by a pixel-defined film PDL (see [link]). Figure 11 ) and the second pixel electrode AE2 (see Figure 11 The second opening overlaps to define the third main emission region MEA3, which can be defined by a pixel-defined film PDL (see [link]). Figure 11 ) and the third pixel electrode AE3 (see Figure 11 The overlapping third opening defines the boundary. Although Figure 11 The fourth main emission region MEA4 is not shown, but it can be defined by a pixel-defined film PDL (see [link]). Figure 11 The fourth opening, which overlaps with the fourth pixel electrode, is used to define the area.

[0128] Multiple main launch areas (MEAs) can be used in PenTile ® Type (genre) (e.g., Diamond PenTile) ® Arrange by type (category). PenTile ®"MEA1" is a registered trademark of Samsung Display Co., Ltd. For example, the first main emission area MEA1 and the third main emission area MEA3 may be spaced apart and / or separated from each other (e.g., spaced apart or separated) in the first direction DR1, and may be arranged alternately and repeatedly in the first direction DR1 and the second direction DR2. The second main emission area MEA2 and the fourth main emission area MEA4 may be spaced apart and / or separated from each other (e.g., spaced apart or separated) in the second direction DR2. The second main emission area MEA2 and the fourth main emission area MEA4 may be spaced apart and / or separated from the adjacent first main emission area MEA1 and the third main emission area MEA3 in the fourth direction DR4 or the fifth direction DR5 (e.g., spaced apart or separated). The second main emission area MEA2 and the fourth main emission area MEA4 may be arranged alternately and repeatedly along the first direction DR1 and the second direction DR2, and the second main emission area MEA2 and the first main emission area MEA1 or the fourth main emission area MEA4 and the third main emission area MEA3 may be arranged alternately and repeatedly along the fourth direction DR4 or the fifth direction DR5.

[0129] In the first diagonal column C1, the first main emission region MEA1 and the fourth main emission region MEA4 of the first main display pixel MDX1 and the first main emission region MEA1 and the fourth main emission region MEA4 of the second main display pixel MDX2 can be arranged in the fifth direction DR5. In the second diagonal column C2, the second main emission region MEA2 and the third main emission region MEA3 of the first main display pixel MDX1 and the second main display pixel MDX2 can be arranged in the fifth direction DR5. In the third diagonal column C3, the first main emission region MEA1 and the fourth main emission region MEA4 of the fourth main display pixel MDX4 and the first main emission region MEA1 and the fourth main emission region MEA4 of the third main display pixel MDX3 can be arranged in the fifth direction DR5. In the fourth diagonal column C4, the second main emission area MEA2 and the third main emission area MEA3 of the fourth main display pixel MDX4 and the second main emission area MEA2 and the third main emission area MEA3 of the third main display pixel MDX3 can be arranged on the fifth direction DR5.

[0130] In the first diagonal row R1, the first main emission region MEA1 and the second main emission region MEA2 of the first main display pixel MDX1, and the first main emission region MEA1 and the second main emission region MEA2 of the fourth main display pixel MDX4 can be arranged on the fourth direction DR4. In the second diagonal row R2, the fourth main emission region MEA4 and the third main emission region MEA3 of the first main display pixel MDX1, and the fourth main emission region MEA4 and the third main emission region MEA3 of the fourth main display pixel MDX4 can be arranged on the fourth direction DR4. In the third diagonal row R3, the first main emission region MEA1 and the second main emission region MEA2 of the second main display pixel MDX2, and the first main emission region MEA1 and the second main emission region MEA2 of the third main display pixel MDX3 can be arranged on the fourth direction DR4. In the fourth diagonal row R4, the fourth main emission area MEA4 and the third main emission area MEA3 of the second main display pixel MDX2 and the third main display pixel MDX3 can be arranged on the fourth direction DR4.

[0131] In one or more embodiments, the areas or dimensions of the first main transmission region MEA1, the second main transmission region MEA2, the third main transmission region MEA3, and the fourth main transmission region MEA4 may be different from each other. Figure 6 In one or more embodiments, the area of ​​the first main emitting region MEA1 may be larger than the area of ​​each of the second main emitting region MEA2, the third main emitting region MEA3, and the fourth main emitting region MEA4, and the area of ​​the third main emitting region MEA3 may be larger than the area of ​​each of the second main emitting region MEA2 and the fourth main emitting region MEA4. The intensity of the emitted light may vary depending on the area of ​​each main emitting region MEA, and the color of the image displayed on the display device 10 can be controlled or selected by adjusting the area of ​​each main emitting region MEA. Figure 6 In one or more embodiments, a first main emitting region MEA1 with the largest area is illustrated, but embodiments of this disclosure are not limited thereto. The size of each main emitting region MEA and the area of ​​the emitting region can be freely and appropriately adjusted depending on the color of the image desired or required by the display device 10. Furthermore, the area of ​​each main emitting region MEA may be related to the light efficiency and / or the light-emitting element ED (see [reference]). Figure 11 The size of the MEA (Medium Emitter Reflector) is related to factors such as its lifetime and may have an inverse relationship with the reflection of external light. These factors can be considered when adjusting the area of ​​each MEA.

[0132] Although the accompanying drawings illustrate one or more embodiments in which each of the main emission regions (MEAs) has a circular planar shape, the embodiments of this disclosure are not limited thereto.

[0133] The display device 10 may include a light-blocking layer BM and a first color filter layer CFL1, a second color filter layer CFL2 and a third color filter layer CFL3 disposed on the light-blocking layer BM.

[0134] The light-blocking layer BM can be arranged throughout the entire display area DA. For example, the light-blocking layer BM can be arranged throughout the main display area MDA and the sub-display area SDA.

[0135] The light-blocking layer BM may include multiple main openings OPT_M disposed in the main display area MDA and arranged to correspond to the main emitting area MEA, respectively. The light-blocking layer BM may cover the main display area MDA except for the area in the main display area MDA where the multiple main openings OPT_M are arranged. The multiple main openings OPT_M of the light-blocking layer BM may be from the light-emitting element ED corresponding to the main emitting area MEA (see...). Figure 11 The area from which the emitted light is emitted.

[0136] Multiple main openings OPT_M may include a first main opening OPT1_M that overlaps with the first main transmission region MEA1, a second main opening OPT2_M that overlaps with the second main transmission region MEA2, a third main opening OPT3_M that overlaps with the third main transmission region MEA3, and a fourth main opening OPT4_M that overlaps with the fourth main transmission region MEA4.

[0137] The planar area of ​​each of the plurality of main openings OPT_M can be greater than the planar area of ​​each corresponding main transmitting region MEA. For example, the planar area of ​​the first main opening OPT1_M can be greater than the planar area of ​​the first main transmitting region MEA1, the planar area of ​​the second main opening OPT2_M can be greater than the planar area of ​​the second main transmitting region MEA2, the planar area of ​​the third main opening OPT3_M can be greater than the planar area of ​​the third main transmitting region MEA3, and the planar area of ​​the fourth main opening OPT4_M can be greater than the planar area of ​​the fourth main transmitting region MEA4. In this disclosure, the terms “planar area,” “planar size,” and “area” or “size” of an element can refer to the projected area of ​​the element on the plane defined by the first direction DR1 and the second direction DR2. For example, when this disclosure refers to the “planar area” or “size” of an element, it refers to the size of the element as presented when the element is tiled onto the surface defined by the two specific directions (DR1 and DR2) when viewed from above.

[0138] The first color filter layer CFL1 can be disposed on the light-blocking layer BM. The second color filter layer CFL2 can be disposed on the first color filter layer CFL1. The third color filter layer CFL3 can be disposed on the second color filter layer CFL2.

[0139] The first color filter layer CFL1 may include a first primary color portion CF1_M arranged in the main display area MDA, the second color filter layer CFL2 may include a second primary color portion CF2_M and a fourth primary color portion CF4_M arranged in the main display area MDA, and the third color filter layer CFL3 may include a third primary color portion CF3_M arranged in the main display area MDA. The first primary color portion CF1_M, the second primary color portion CF2_M, the third primary color portion CF3_M, and the fourth primary color portion CF4_M may be included in the primary color portion CF_M.

[0140] The primary color portion CF_M may contain colorants (such as dyes and / or pigments) that absorb light in bands other than a specific wavelength, and may be arranged to correspond to the light-emitting element ED (see [link to colorimetric analysis]). Figure 11 The color of the emitted light. For example, in one or more embodiments, the first primary color portion CF1_M may be a red color filter that transmits only red light and is arranged to overlap with the first primary emission region MEA1. The second primary color portion CF2_M may be a green color filter that transmits only green light and is arranged to overlap with the second primary emission region MEA2. The third primary color portion CF3_M may be a blue color filter that transmits only blue light and is arranged to overlap with the third primary emission region MEA3, and the fourth primary color portion CF4_M may be a green color filter that transmits only green light and is arranged to overlap with the fourth primary emission region MEA4.

[0141] Multiple primary color portions CF_M can be arranged to correspond to multiple primary emission regions MEA, respectively. For example, in one or more embodiments, a first primary color portion CF1_M can be arranged to overlap with a first primary emission region MEA1, a second primary color portion CF2_M can be arranged to overlap with a second primary emission region MEA2, a third primary color portion CF3_M can be arranged to overlap with a third primary emission region MEA3, and a fourth primary color portion CF4_M can be arranged to overlap with a fourth primary emission region MEA4.

[0142] Similar to the layout of the main emission area MEA, the main color area CF_M can be arranged in PenTile format. ® Type (genre) (e.g., Diamond PenTile) ®The primary color portions CF1_M and CF3_M can be arranged according to their type (category). For example, the first primary color portion CF1_M and the third primary color portion CF3_M can be spaced apart and / or separated from each other in the first direction DR1 (e.g., spaced apart or separated), and can be arranged alternately and repeatedly in the first direction DR1 and the second direction DR2. The second primary color portion CF2_M and the fourth primary color portion CF4_M can be spaced apart and / or separated from each other in the second direction DR2 (e.g., spaced apart or separated). The second primary color portion CF2_M and the fourth primary color portion CF4_M can be spaced apart and / or separated from the adjacent first primary color portion CF1_M and third primary color portion CF3_M in the fourth direction DR4 or the fifth direction DR5 (e.g., spaced apart or separated). The second primary color portion CF2_M and the fourth primary color portion CF4_M can be arranged alternately and repeatedly along the first direction DR1 and the second direction DR2, and the second primary color portion CF2_M and the first primary color portion CF1_M or the fourth primary color portion CF4_M and the third primary color portion CF3_M can be arranged alternately and repeatedly along the fourth direction DR4 or the fifth direction DR5.

[0143] The planar dimensions or areas of the multiple primary color portions CF_M can be different from each other. As described above, the dimensions or areas of the multiple primary emission regions MEA can be different from each other, such that the planar dimensions or areas of the multiple primary color portions CF_M can also be different from each other. For example, in one or more embodiments, the size or area of ​​the first primary color portion CF1_M can be larger than the size or area of ​​each of the second primary color portion CF2_M, the third primary color portion CF3_M, and the fourth primary color portion CF4_M. Furthermore, the size or area of ​​the third primary color portion CF3_M can be larger than the size or area of ​​each of the second primary color portion CF2_M and the fourth primary color portion CF4_M.

[0144] The planar area of ​​each of the multiple primary color portions CF_M can be greater than the planar area of ​​each corresponding primary emission region MEA. For example, the planar area of ​​the first primary color portion CF1_M can be greater than the planar area of ​​the first primary emission region MEA1, the planar area of ​​the second primary color portion CF2_M can be greater than the planar area of ​​the second primary emission region MEA2, the planar area of ​​the third primary color portion CF3_M can be greater than the planar area of ​​the third primary emission region MEA3, and the planar area of ​​the fourth primary color portion CF4_M can be greater than the planar area of ​​the fourth primary emission region MEA4.

[0145] Multiple primary color portions CF_M can be arranged to correspond to multiple primary openings OPT_M of the light-blocking layer BM, respectively. For example, the first primary color portion CF1_M can be arranged to overlap with the first primary opening OPT1_M of the light-blocking layer BM, the second primary color portion CF2_M can be arranged to overlap with the second primary opening OPT2_M of the light-blocking layer BM, the third primary color portion CF3_M can be arranged to overlap with the third primary opening OPT3_M of the light-blocking layer BM, and the fourth primary color portion CF4_M can be arranged to overlap with the fourth primary opening OPT4_M of the light-blocking layer BM.

[0146] The planar area of ​​each of the multiple primary color portions CF_M can be larger than the planar area of ​​each corresponding primary opening OPT_M of the light-blocking layer BM. For example, the planar area of ​​the first primary color portion CF1_M can be larger than the planar area of ​​the first primary opening OPT1_M of the light-blocking layer BM, the planar area of ​​the second primary color portion CF2_M can be larger than the planar area of ​​the second primary opening OPT2_M of the light-blocking layer BM, the planar area of ​​the third primary color portion CF3_M can be larger than the planar area of ​​the third primary opening OPT3_M of the light-blocking layer BM, and the planar area of ​​the fourth primary color portion CF4_M can be larger than the planar area of ​​the fourth primary opening OPT4_M of the light-blocking layer BM. Accordingly, the multiple primary color portions CF_M can each completely cover the primary opening OPT_M of the light-blocking layer BM.

[0147] Although the accompanying drawings illustrate one or more embodiments in which each of the main color portions CF_M has a circular planar shape, the embodiments of this disclosure are not limited thereto.

[0148] Figure 11 According to one or more embodiments along Figure 6 The cross-sectional view taken by line X2-X2'. Figure 11 The figure shows a cross-section of the first main emission region MEA1, the second main emission region MEA2, and the third main emission region MEA3 spanning the first main display pixel MDX1 in the main display area MDA. The fourth main emission region MEA4 has a structure substantially the same as that of the second main emission region MEA2 and is therefore omitted.

[0149] Apart from Figures 6 to 10 In addition, refer to Figure 11 The display panel 100 of the display device 10 may include a display layer DU, a touch sensing layer TSU, and a color filter layer CFL. 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.

[0150] The substrate SUB can be a base substrate or a base member. The substrate SUB can be a flexible substrate that can be bent, folded, or rolled. For example, in one or more embodiments, the substrate SUB may include a polymer resin such as polyimide, but embodiments of this disclosure are not limited thereto.

[0151] 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).

[0152] The first buffer layer BF1 may be disposed on the substrate SUB. The first buffer layer BF1 may include an inorganic membrane capable of preventing or reducing the penetration of air and / or moisture. For example, in one or more embodiments, the first buffer layer BF1 may include a plurality of inorganic membranes stacked alternately.

[0153] The lower metal layer BML can be disposed on the first buffer layer BF1. For example, the lower metal layer BML can 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 their alloys.

[0154] The second buffer layer BF2 may cover the first buffer layer BF1 and the lower metal layer BML. The second buffer layer BF2 may include an inorganic membrane capable of preventing or reducing the penetration of air and / or moisture. For example, in one or more embodiments, the second buffer layer BF2 may include a plurality of inorganic membranes stacked alternately.

[0155] Thin-film transistors (TFTs) can be disposed on the second buffer layer BF2 and can constitute the pixel circuit for each of a plurality of pixels. For example, the TFT can be a switching transistor or a driving transistor of the pixel circuit. The TFT may include a semiconductor layer ACT, a source electrode SE, a drain electrode DE, and a gate electrode GE.

[0156] The semiconductor layer ACT can be disposed on the second buffer layer BF2. The semiconductor layer ACT can overlap with the lower metal layer BML and the gate electrode GE in the thickness direction, and can be insulated from the gate electrode GE by the gate insulating layer GI. In a portion of the semiconductor layer ACT, the material of the semiconductor layer ACT can be fabricated as a conductor to form the source electrode SE and the drain electrode DE.

[0157] The gate electrode GE can be disposed on the gate insulating layer GI. The gate electrode GE can overlap with the semiconductor layer ACT, with the gate insulating layer GI inserted between them.

[0158] The gate insulating layer GI can be disposed on the semiconductor layer ACT. For example, the gate insulating layer GI can cover the semiconductor layer ACT and the second buffer layer BF2 to insulate the gate electrode GE from the semiconductor layer ACT. The gate insulating layer GI may include a contact hole through which the first connection electrode CNE1 passes.

[0159] 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.

[0160] The capacitor electrode CPE can be disposed on the first interlayer insulating layer ILD1. The capacitor electrode CPE can overlap with the gate electrode GE in the thickness direction. The capacitor electrode CPE and the gate electrode GE can form a capacitor.

[0161] 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.

[0162] The first connection electrode CNE1 may be disposed on the second interlayer insulating layer ILD2. In one or more embodiments, the first connection electrode CNE1 may electrically connect the drain electrode DE of the thin-film transistor TFT to the second connection electrode CNE2. The first connection electrode CNE1 may be inserted into a contact hole provided in the second interlayer insulating layer ILD2, the first interlayer insulating layer ILD1, and the gate insulating layer GI to contact the drain electrode DE of the thin-film transistor TFT.

[0163] The first passivation layer PAS1 can cover the first connection electrode CNE1 and the second interlayer insulating layer ILD2. The first passivation layer PAS1 can protect the thin-film transistor (TFT). The first passivation layer PAS1 may include a contact hole through which the second connection electrode CNE2 passes.

[0164] The second connection electrode CNE2 can 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 (such as AE1, AE2 or AE3) of the light-emitting element ED. The second connection electrode CNE2 can be inserted into a contact hole formed in the first passivation layer PAS1 to contact the first connection electrode CNE1.

[0165] 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 contact holes through which pixel electrodes (such as AE1, AE2 or AE3) of the light-emitting element ED pass.

[0166] The light-emitting element layer (EML) can be disposed on the thin-film transistor layer (TFTL). The EML may include a light-emitting element (ED) and a pixel defining film (PDL). The light-emitting element (ED) may include a pixel electrode selected from the respective pixel electrodes AE1, AE2, and AE3, a light-emitting layer (EL), and a common electrode (CE).

[0167] Pixel electrodes AE1, AE2, and AE3 can be disposed on the second passivation layer PAS2. Different pixel electrodes AE1, AE2, and AE3 can each be arranged to overlap with a corresponding opening in the pixel-defining film PDL. Pixel electrodes AE1, AE2, and AE3 can each be electrically connected to the drain electrode DE of a corresponding thin-film transistor (TFT) via a first connection electrode CNE1 and a second connection electrode CNE2.

[0168] The light-emitting layer EL can be disposed separately and independently on the pixel electrodes AE1, AE2, and AE3. For example, the light-emitting layer EL can be an organic light-emitting layer made of organic materials, but the embodiments of this disclosure are not limited thereto. In embodiments using an organic light-emitting layer as the light-emitting layer EL, the thin-film transistor TFT applies a set or predetermined voltage to the corresponding pixel electrode AE1, AE2, or AE3 of the light-emitting element ED, and if the common electrode CE of the light-emitting element ED receives a common voltage or a cathode voltage (e.g., when the common electrode CE of the light-emitting element ED receives a common voltage or a cathode voltage), holes and electrons can move to the light-emitting layer EL through the hole transport layer and the electron transport layer, respectively, and recombine with each other in the light-emitting layer EL to emit light.

[0169] In one or more embodiments, the light-emitting layers EL disposed on different pixel electrodes AE1, AE2, and AE3 can emit light of different colors. For example, in one or more embodiments, the light-emitting layer EL disposed on the first pixel electrode AE1 can emit red light of a first color, the light-emitting layer EL disposed on the second pixel electrode AE2 can emit green light of a second color, and the light-emitting layer EL disposed on the third pixel electrode AE3 can emit blue light of a third color. However, the embodiments of this disclosure are not limited thereto. In one or more embodiments, the light-emitting layer EL can be disposed as a single common layer on different pixel electrodes AE1, AE2, and AE3 and the pixel defining film PDL, and the light-emitting layers EL disposed on different pixel electrodes AE1, AE2, and AE3 can emit light of the same color. In these embodiments, the display device 10 may further include a color adjustment layer disposed on the light-emitting element ED.

[0170] The common electrode CE can be disposed on the light-emitting layer EL. For example, in one or more embodiments, the common electrode CE can be made in the form of an electrode shared by all pixels in a pixel rather than an electrode specific to each pixel. The common electrode CE can be disposed on the light-emitting layer EL in contrast to the pixel electrodes AE1, AE2, and AE3, and can be disposed on the pixel-defining film PDL in the area other than the pixel electrodes AE1, AE2, and AE3.

[0171] The common electrode CE can receive a common voltage or a low potential voltage. When pixel electrodes AE1, AE2, and AE3 each receive a voltage corresponding to the data voltage and the common electrode CE receives a low potential voltage, a potential difference is formed between each of the pixel electrodes AE1, AE2, and AE3 and the common electrode CE, allowing the light-emitting layer EL to emit light.

[0172] The pixel-defining film (PDL) may include multiple openings and may be disposed on a portion of the pixel electrodes AE1, AE2, and AE3 and the second passivation layer PAS2. Each opening in the pixel-defining film PDL may expose a portion of a corresponding one of the pixel electrodes AE1, AE2, and AE3. As described above, the corresponding openings in the pixel-defining film PDL may define a first main emitting region MEA1, a second main emitting region MEA2, and a third main emitting region MEA3, and their areas or dimensions may differ from each other. The pixel-defining film PDL may separate and insulate the pixel electrodes AE1, AE2, and AE3 of multiple light-emitting elements (EDs).

[0173] Pixel-defined films (PDLs) may include light-absorbing materials to prevent or reduce light reflection. For example, in one or more embodiments, a pixel-defined film PDL may include a polyimide (PI) binder and a light-absorbing material in which pigments absorbing red, green, and blue light are mixed. In one or more embodiments, a pixel-defined film PDL may include a cardo-based binder resin and a mixture of lactam black and blue pigments (e.g., any suitable). In one or more embodiments, a pixel-defined film PDL may include carbon black.

[0174] The encapsulation layer TFEL can be disposed on the common electrode CE to cover multiple light-emitting elements ED.

The encapsulation layer TFEL may also include at least one organic film to protect the light-emitting element layer EML from foreign matter such as dust.

[0175] In one or more embodiments, the encapsulation layer TFEL may include a first encapsulation layer TFE1, a second encapsulation layer TFE2, and a third encapsulation layer TFE3. 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.

The second encapsulation layer TFE2 may be formed by curing monomers or by applying a polymer.

[0178] The touch sensing layer (TSU) can be disposed on the encapsulation layer (TFEL). The touch sensing layer (TSU) may include a first touch insulating layer (SIL1), a second touch insulating layer (SIL2), a touch electrode (TL), and a third touch insulating layer (SIL3).

[0179] The first touch insulating layer SIL1 may be disposed on the encapsulation layer TFEL. The first touch insulating layer SIL1 may have both insulating and optical functions.

[0182] The touch electrode TL of the touch sensing layer TSU can have a constant linewidth and can be arranged to overlap with the light-blocking layer BM. The light-blocking layer BM can have a width sufficient to completely cover the touch electrode TL. In one or more embodiments, the touch electrode TL can be arranged such that its central portion is substantially parallel to the central portion of the light-blocking layer BM, and the distance from one side of the touch electrode TL to one side of the light-blocking layer BM can be substantially equal to the distance from the other side of the touch electrode TL to the other side of the light-blocking layer BM.

[0183] The third touch insulating layer SIL3 may cover the touch electrode TL and the second touch insulating layer SIL2.

[0187] The area or size of each of the main openings OPT_M can be larger than the area or size of the corresponding main emitting region MEA. Furthermore, the area or size of each of the main openings OPT_M can be formed to be larger than the area or size of the corresponding opening of the pixel defining film PDL, and the light emitted from the light-emitting element ED can be visually recognized by the user not only from the front of the display device 10 but also from its side.

[0188] The light-blocking layer BM may include a light-absorbing material. For example, in one or more embodiments, the light-blocking layer BM may include an inorganic black pigment and / or an organic black pigment. The inorganic black pigment may be carbon black, and the organic black pigment may include at least one of lactam black, perylene black, and aniline black, but they are not limited thereto.

[0189] The first color filter layer CFL1, the second color filter layer CFL2, and the third color filter layer CFL3 may be disposed on the light-blocking layer BM. In one or more embodiments, the first color filter layer CFL1, the second color filter layer CFL2, and the third color filter layer CFL3 may be stacked sequentially on the light-blocking layer BM, but the embodiments disclosed herein are not limited thereto.

[0196] Apart from Figures 5 to 11 In addition, it also refers to Figures 12 to 16 The sub-display area SDA may include multiple sub-display pixels SDX. These multiple sub-display pixels SDX can be arranged on the fourth direction DR4 and the fifth direction DR5. The sub-display pixels SDX can be distributed throughout the entire sub-display area SDA. Figure 12 The arrangement method is repeated.

[0199] The sub-emitting region (SEA) can be the luminescent layer (EL) (see Figure 17 ) and the corresponding pixel electrodes AE1, AE2 or AE3 (see Figure 17 Overlapping areas.

For example, the sub-emitting region (SEA) can be formed by the light-emitting element layer (EML) (see [link to EML]). Figure 17 Pixel-limited film PDL (see) Figure 17 It is defined by multiple openings.

[0200] The first sub-emission region SEA1 can be defined by a pixel-defined film PDL (see...).

Figure 17 ) and the second pixel electrode AE2 (see Figure 17 The second opening overlaps to define the third sub-emission region SEA3, which can be defined by the pixel-defined film PDL (see [link]). Figure 17 ) and the third pixel electrode AE3 (see Figure 17 The overlapping third opening defines the boundary. Although Figure 17 Not shown in the text, but as Figure 12 As shown, the fourth sub-emission region SEA4 can be defined by a pixel-defined film PDL (see...). Figure 17 The fifth sub-emission region SEA5 is defined by a fourth opening overlapping with the fourth pixel electrode, and can be defined by a pixel-defined film PDL (see [link to PDL]).

Figure 17 The sixth opening, overlapping with the sixth pixel electrode, defines the seventh sub-emission region SEA7, which can be defined by the pixel-defined film PDL (see [link to PDL]). Figure 17 The seventh opening, which overlaps with the seventh pixel electrode, is used to define the area.

[0201] Multiple sub-emitting regions (SEAs) can be arranged in a first sub-slant column SC1 and a second sub-slant column SC2. The first sub-slant column SC1 can be a region in the sub-display region SDA that extends in the fourth direction DR4 without overlapping with the transmission region TA, and the second sub-slant column SC2 can be a region in the sub-display region SDA that extends in the fifth direction DR5 without overlapping with the transmission region TA.

The intensity of the emitted light may vary depending on the area of ​​each sub-emitting region SEA, and the color of the image displayed on the display device 10 can be controlled or selected by adjusting the area of ​​each sub-emitting region SEA. Figure 12 In one or more embodiments, a first sub-emission region SEA1 and a fourth sub-emission region SEA4 with the largest area are illustrated, but the embodiments disclosed herein are not limited thereto. The size of each sub-emission region SEA and the area of ​​the emission region can be freely and appropriately adjusted depending on the color of the image desired or required by the display device 10. Furthermore, the area of ​​each sub-emission region SEA may be related to the luminous efficiency and / or the light-emitting element ED (see [reference]). Figure 17 The size of the sub-emitting area (SEA) is related to factors such as its lifetime and may have an inverse relationship with the reflection of external light. These factors can be considered when adjusting the area of ​​each SEA.

[0204] Although the accompanying drawings illustrate that each of the sub-emission regions (SEAs) of one or more embodiments has a quadrilateral shape with rounded corners in a plan view, the embodiments of this disclosure are not limited thereto.

[0214] The secondary color portion CF_S may contain colorants (such as dyes and / or pigments) that absorb light in bands other than a specific wavelength, and may be arranged to correspond to the light-emitting element ED (see [link to RGB image]). Figure 17 The color of the emitted light. For example, in one or more embodiments, the first sub-color portion CF1_S and the fourth sub-color portion CF4_S may be red filters that transmit only red light and are arranged to overlap with the first sub-emission region SEA1 and the fourth sub-emission region SEA4, respectively.

[0216] In the first sub-diagonal column SC1, the first sub-color portion CF1_S, the second sub-color portion CF2_S, the fourth sub-color portion CF4_S, and the fifth sub-color portion CF5_S can be arranged sequentially in the fourth direction DR4. In the second sub-diagonal column SC2, the third sub-color portion CF3_S, the second sub-color portion CF2_S, the sixth sub-color portion CF6_S, and the seventh sub-color portion CF7_S can be arranged sequentially in the fifth direction DR5.

[0217] In the first sub-diagonal column SC1, the first sub-color portion CF1_S and the fourth sub-color portion CF4_S can be alternately arranged to be spaced apart and / or separated from each other in the fourth direction DR4 (e.g., spaced apart or separated). In the first sub-diagonal column SC1, the second sub-color portion CF2_S and the fifth sub-color portion CF5_S can be alternately arranged to be spaced apart and / or separated from each other in the fourth direction DR4 (e.g., spaced apart or separated). In the second sub-diagonal column SC2, the second sub-color portion CF2_S and the seventh sub-color portion CF7_S can be alternately arranged to be spaced apart and / or separated from each other in the fifth direction DR5 (e.g., spaced apart or separated). In the second sub-diagonal column SC2, the third sub-color portion CF3_S and the sixth sub-color portion CF6_S can be alternately arranged to be spaced apart and / or separated from each other in the fifth direction DR5 (e.g., spaced apart or separated).

[0218] The planar dimensions or areas of the multiple sub-color portions CF_S can be different from each other. As described above, the dimensions or areas of the multiple sub-emission regions SEA can be different from each other, such that the planar dimensions or areas of the multiple sub-color portions CF_S can also be different from each other. For example, in one or more embodiments, the size or area of ​​each of the third sub-color portion CF3_S and the sixth sub-color portion CF6_S can be larger than the size or area of ​​each of the first sub-color portion CF1_S, the second sub-color portion CF2_S, the fourth sub-color portion CF4_S, the fifth sub-color portion CF5_S, and the seventh sub-color portion CF7_S. Furthermore, the size or area of ​​each of the first sub-color portion CF1_S and the fourth sub-color portion CF4_S can be larger than the size or area of ​​each of the second sub-color portion CF2_S, the fifth sub-color portion CF5_S, and the seventh sub-color portion CF7_S. The size of each of the multiple sub-color portions CF_S is closely related to the color of the sub-display region SDA, and will be referred to later. Figure 20 This will be described in more detail.

[0219] The planar area of ​​each of the multiple sub-color portions CF_S can be greater than the planar area of ​​each corresponding sub-emission region SEA. For example, the planar area of ​​the first sub-color portion CF1_S can be greater than the planar area of ​​the first sub-emission region SEA1, the planar area of ​​the second sub-color portion CF2_S can be greater than the planar area of ​​the second sub-emission region SEA2, the planar area of ​​the third sub-color portion CF3_S can be greater than the planar area of ​​the third sub-emission region SEA3, the planar area of ​​the fourth sub-color portion CF4_S can be greater than the planar area of ​​the fourth sub-emission region SEA4, the planar area of ​​the fifth sub-color portion CF5_S can be greater than the planar area of ​​the fifth sub-emission region SEA5, the planar area of ​​the sixth sub-color portion CF6_S can be greater than the planar area of ​​the sixth sub-emission region SEA6, and the planar area of ​​the seventh sub-color portion CF7_S can be greater than the planar area of ​​the seventh sub-emission region SEA7.

[0220] Multiple sub-color portions CF_S can be arranged to correspond to multiple sub-apertures OPT_S of the light-blocking layer BM, respectively. For example, the first sub-color portion CF1_S can be arranged to overlap with the first sub-aperture OPT1_S of the light-blocking layer BM, the second sub-color portion CF2_S can be arranged to overlap with the second sub-aperture OPT2_S of the light-blocking layer BM, the third sub-color portion CF3_S can be arranged to overlap with the third sub-aperture OPT3_S of the light-blocking layer BM, the fourth sub-color portion CF4_S can be arranged to overlap with the fourth sub-aperture OPT4_S of the light-blocking layer BM, the fifth sub-color portion CF5_S can be arranged to overlap with the fifth sub-aperture OPT5_S of the light-blocking layer BM, the sixth sub-color portion CF6_S can be arranged to overlap with the sixth sub-aperture OPT6_S of the light-blocking layer BM, and the seventh sub-color portion CF7_S can be arranged to overlap with the seventh sub-aperture OPT7_S of the light-blocking layer BM.

[0221] The planar area of ​​each of the multiple sub-color portions CF_S can be greater than the planar area of ​​each corresponding sub-aperture OPT_S of the light-blocking layer BM. For example, the planar area of ​​the first sub-color portion CF1_S can be greater than the planar area of ​​the first sub-aperture OPT1_S of the light-blocking layer BM, the planar area of ​​the second sub-color portion CF2_S can be greater than the planar area of ​​the second sub-aperture OPT2_S of the light-blocking layer BM, the planar area of ​​the third sub-color portion CF3_S can be greater than the planar area of ​​the third sub-aperture OPT3_S of the light-blocking layer BM, the planar area of ​​the fourth sub-color portion CF4_S can be greater than the planar area of ​​the fourth sub-aperture OPT4_S of the light-blocking layer BM, the planar area of ​​the fifth sub-color portion CF5_S can be greater than the planar area of ​​the fifth sub-aperture OPT5_S of the light-blocking layer BM, the planar area of ​​the sixth sub-color portion CF6_S can be greater than the planar area of ​​the sixth sub-aperture OPT6_S of the light-blocking layer BM, and the planar area of ​​the seventh sub-color portion CF7_S can be greater than the planar area of ​​the seventh sub-aperture OPT7_S of the light-blocking layer BM. Correspondingly, multiple sub-color portions CF_S can completely cover the sub-openings OPT_S of the light-blocking layer BM.

[0222] Although the accompanying drawings illustrate one or more embodiments in which each of the sub-color portions CF_S has a substantially quadrilateral planar shape, the embodiments of this disclosure are not limited thereto.

[0223] In the display device 10 according to this embodiment, the area ratio of colors in the main emission region MEA of the main display pixel MDX may be different from the area ratio of colors in the sub-emission region SEA of the sub-display pixel SDX. For example, the ratio of the area of ​​the first main emission region MEA1 emitting red light in the main display pixel MDX to the sum of the areas of the second main emission regions MEA2 and the fourth main emission regions MEA4 emitting green light, and the ratio to the area of ​​the third main emission region MEA3 emitting blue light, may be different from the ratio of the sum of the areas of the first sub-emission regions SEA1 and the fourth sub-emission regions SEA4 emitting red light in the sub-display pixel SDX to the sum of the areas of the second sub-emission regions SEA2, the fifth sub-emission regions SEA5 and the seventh sub-emission regions SEA7 emitting green light, and the ratio to the sum of the areas of the third sub-emission regions SEA3 and the sixth sub-emission regions SEA6 emitting blue light. Furthermore, in the display device 10 according to this embodiment, the area ratio between the first main color portion CF1_M, the second main color portion CF2_M and the third main color portion CF3_M may be different from the area ratio between the first secondary color portion CF1_S, the second secondary color portion CF2_S and the third secondary color portion CF3_S.

[0224] In one or more embodiments, in the main display pixel MDX, the area of ​​the first main emitting region MEA1 emitting red light can be more than 25% of the total area (i.e., the sum of the areas of the first main emitting region MEA1, the second main emitting region MEA2, the third main emitting region MEA3, and the fourth main emitting region MEA4), the sum of the areas of the second main emitting region MEA2 and the fourth main emitting region MEA4 emitting green light can be more than 50% of the total area, and the area of ​​the third main emitting region MEA3 emitting blue light can be less than 20% of the total area.

[0225] In one or more embodiments, in the sub-display pixel SDX, the sum of the areas of the first sub-emitting region SEA1 and the fourth sub-emitting region SEA4 emitting red light can be more than 25% of the total area (i.e., the sum of the areas of the first sub-emitting region SEA1, the second sub-emitting region SEA2, the third sub-emitting region SEA3, the fourth sub-emitting region SEA4, the fifth sub-emitting region SEA5, the sixth sub-emitting region SEA6, and the seventh sub-emitting region SEA7), the sum of the areas of the second sub-emitting region SEA2, the fifth sub-emitting region SEA5, and the seventh sub-emitting region SEA7 emitting green light can be less than 50% of the total area, and the sum of the areas of the third sub-emitting region SEA3 and the sixth sub-emitting region SEA6 emitting blue light can be more than 20% of the total area.

[0226] In the display device 10 according to this embodiment, the ratio of the area of ​​the sub-emitting region SEA emitting green light in the sub-display pixel SDX to the area of ​​the entire sub-emitting region SEA can be smaller than the ratio of the area of ​​the main emitting region MEA emitting green light in the main display pixel MDX to the area of ​​the entire main emitting region MEA. Accordingly, a color difference may occur between the main emitting region MEA and the sub-emitting region SEA.

[0227] Furthermore, in one or more embodiments, the fifth sub-color portion CF5_S can be arranged on the fifth direction DR5 between the transmissive regions TA, and the seventh sub-color portion CF7_S can be arranged on the fourth direction DR4 between the transmissive regions TA. For example, since the sub-emission region SEA and the sub-color portion CF_S are arranged in the bridging region BRA to improve the resolution of the sub-display region SDA, a color difference may occur between the main emission region MEA and the sub-emission region SEA.

[0228] In the display device 10 according to this embodiment, in order to minimize or reduce the color difference between the main emitting region MEA and the sub-emitting region SEA, the size or area of ​​the seventh sub-color portion CF7_S of the green color filter can be increased. For example, the length of the seventh sub-color portion CF7_S in the fourth direction DR4 can be greater than its length in the fifth direction DR5. The lengths of both ends of the seventh sub-color portion CF7_S in the fourth direction DR4 can be extended so that they are arranged adjacent to the transmission region TA.

[0229] In one or more embodiments, although not shown in the figures, the size or area of ​​the fifth sub-color portion CF5_S of the green color filter can be enlarged. For example, the length of the fifth sub-color portion CF5_S in the fifth direction DR5 can be greater than its length in the fourth direction DR4. The lengths of both ends of the fifth sub-color portion CF5_S in the fifth direction DR5 can be extended such that they are arranged adjacent to the transmission region TA.

[0230] Even if the area of ​​the sub-emitting region SEA that emits green light becomes smaller than the area of ​​the main emitting region MEA that emits green light, the color reflected by the green color filter will increase due to the increase in the size or area of ​​the seventh sub-color part CF7_S or the fifth sub-color part CF5_S, thereby minimizing or reducing the color difference between the main display pixel MDX and the sub-display pixel SDX.

[0231] The size or area of ​​the seventh sub-color portion CF7_S can be larger than that of the second sub-color portion CF2_S. In one or more embodiments, although not shown in the figures, the size or area of ​​the fifth sub-color portion CF5_S can be larger than that of the second sub-color portion CF2_S. The second sub-color portion CF2_S is located in the central region CTA and is directly adjacent to the red and blue emission regions in the fourth direction DR4 and the fifth direction DR5. Therefore, if the size or area of ​​the second sub-color portion CF2_S is increased (e.g., when the size or area of ​​the second sub-color portion CF2_S is increased), the red and blue colors may be affected. In contrast, the fifth sub-color portion CF5_S is arranged adjacent to the transmission region TA in the fifth direction DR5, and the seventh sub-color portion CF7_S is arranged adjacent to the transmission region TA in the fourth direction DR4. Therefore, by increasing the size or area of ​​the fifth sub-color portion CF5_S and / or the seventh sub-color portion CF7_S, the impact on the red and blue colors can be minimized or reduced.

[0232] Simultaneously, the transmission region TA is arranged in the sub-display region SDA, and the underlying layer (e.g., the first passivation layer PAS1 (see...) Figure 18 The first passivation layer, such as PAS1 (see [reference]), can be exposed in the transmission region TA. Figure 18 The unique color of the lower layer (e.g., yellowish) may be exposed through the transmissive area TA, thus potentially causing a color difference between the sub-display area SDA and the main display area MDA.

[0233] In the display device 10 according to this embodiment, in order to minimize or reduce the color difference between the main display area MDA and the sub-display area SDA, the size or area of ​​the third sub-color portion CF3_S and the sixth sub-color portion CF6_S of the blue color filter can be enlarged. Furthermore, the size or area of ​​the first sub-color portion CF1_S and the fourth sub-color portion CF4_S of the red color filter can be enlarged.

[0234] For example, in one or more embodiments, the area of ​​the third sub-color portion CF3_S excluding the area of ​​the third sub-emission region SEA3 and the area of ​​the sixth sub-color portion CF6_S excluding the area of ​​the sixth sub-emission region SEA6 can be larger than the area of ​​the second sub-color portion CF2_S excluding the area of ​​the second sub-emission region SEA2, the area of ​​the fifth sub-color portion CF5_S excluding the area of ​​the fifth sub-emission region SEA5, and the area of ​​the seventh sub-color portion CF7_S excluding the area of ​​the seventh sub-emission region SEA7. Similarly, the area of ​​the first sub-color portion CF1_S excluding the area of ​​the first sub-emission region SEA1 and the area of ​​the fourth sub-color portion CF4_S excluding the area of ​​the fourth sub-emission region SEA4 can be larger than the area of ​​the second sub-color portion CF2_S excluding the area of ​​the second sub-emission region SEA2, the area of ​​the fifth sub-color portion CF5_S excluding the area of ​​the fifth sub-emission region SEA5, and the area of ​​the seventh sub-color portion CF7_S excluding the area of ​​the seventh sub-emission region SEA7.

[0235] For example, in one or more embodiments, the area of ​​the top surface of the light-blocking layer BM of the second sub-color portion CF2_S, the fifth sub-color portion CF5_S, and the seventh sub-color portion CF7_S may be smaller than the area of ​​the top surface of the light-blocking layer BM of the first sub-color portion CF1_S and the fourth sub-color portion CF4_S, as well as the area of ​​the top surface of the light-blocking layer BM of the third sub-color portion CF3_S and the sixth sub-color portion CF6_S.

[0236] In one or more embodiments, the length of each of the third sub-color portion CF3_S and the sixth sub-color portion CF6_S in the fourth direction DR4 may be greater than the length of each of the second sub-color portion CF2_S, the fifth sub-color portion CF5_S, and the seventh sub-color portion CF7_S in the fourth direction DR4. Similarly, the length of each of the third sub-color portion CF3_S and the sixth sub-color portion CF6_S in the fifth direction DR5 may be greater than the length of each of the second sub-color portion CF2_S, the fifth sub-color portion CF5_S, and the seventh sub-color portion CF7_S in the fifth direction DR5.

[0237] Similarly, the length of each of the first sub-color portion CF1_S and the fourth sub-color portion CF4_S in the fourth direction DR4 can be greater than the length of each of the second sub-color portion CF2_S and the fifth sub-color portion CF5_S in the fourth direction DR4. Although not shown in the figures, in one or more embodiments, the length of each of the first sub-color portion CF1_S and the fourth sub-color portion CF4_S in the fifth direction DR5 can be extended such that the length of each of the first sub-color portion CF1_S and the fourth sub-color portion CF4_S in the fifth direction DR5 becomes greater than the length of each of the second sub-color portion CF2_S, the fifth sub-color portion CF5_S, and the seventh sub-color portion CF7_S in the fifth direction DR5.

[0238] In one or more embodiments, the sum of the areas of the first sub-color portion CF1_S and the fourth sub-color portion CF4_S of the red color filter can be 25% or more of the total area (i.e., the sum of the areas of the first sub-color portion CF1_S, the second sub-color portion CF2_S, the third sub-color portion CF3_S, the fourth sub-color portion CF4_S, the fifth sub-color portion CF5_S, the sixth sub-color portion CF6_S, and the seventh sub-color portion CF7_S of the green color filter can be less than 40% of the total area, and the sum of the areas of the third sub-color portion CF3_S and the sixth sub-color portion CF6_S of the blue color filter can be 40% or more of the total area.

[0239] In this way, by increasing the size or area of ​​the sub-color portion CF_S that reflects a specific color, the color difference between the sub-display area SDA and the main display area MDA can be minimized or reduced. This color difference may occur due to the exposure of the underlying layer caused by the arrangement of the transmission area TA.

[0240] Figure 17 It is according to one or more embodiments of this disclosure. Figure 12 The cross-sectional view taken by line X3-X3'. Figure 18 It is according to one or more embodiments of this disclosure. Figure 12 The cross-sectional view taken by line X4-X4'. Figure 19 It is according to one or more embodiments of this disclosure. Figure 12 The cross-sectional view taken from line X5-X5'.

[0241] Apart from Figures 5 to 16 In addition, it also refers to Figures 17 to 19 The display layer DU and the touch sensing layer TSU have already been described above, and therefore will not be repeated for the sake of brevity.

[0242] The color filter layer CFL may include a light-blocking layer BM, a first color filter layer CFL1, a second color filter layer CFL2, a third color filter layer CFL3, and an outer coating layer OC.

[0243] The light-blocking layer BM may include multiple sub-apertures OPT_S arranged to overlap with the sub-emission region SEA. For example, a first sub-aperture OPT1_S may overlap with a first sub-emission region SEA1 on a third-direction DR3, a second sub-aperture OPT2_S may overlap with a second sub-emission region SEA2 on a third-direction DR3, and a third sub-aperture OPT3_S may overlap with a third sub-emission region SEA3 on a third-direction DR3. Although Figure 17 Not shown in the text, but as Figure 12 As shown, the fourth aperture OPT4_S can overlap with the fourth transmit region SEA4 on the third-direction DR3, the fifth aperture OPT5_S can overlap with the fifth transmit region SEA5 on the third-direction DR3, the sixth aperture OPT6_S can overlap with the sixth transmit region SEA6 on the third-direction DR3, and the seventh aperture OPT7_S can overlap with the seventh transmit region SEA7 on the third-direction DR3.

[0244] The area or size of each of the sub-openings OPT_S can be larger than the area or size of the corresponding sub-emitting region SEA. Furthermore, the area or size of each of the sub-openings OPT_S can be formed to be larger than the area or size of the corresponding opening of the pixel-defining film PDL, and the light emitted from the light-emitting element ED can be visually recognized by the user not only from the front of the display device 10 but also from its side.

[0245] The sub-color portion CF_S of the color filter layer CFL can include the first sub-color portion CF1_S of the first color filter layer CFL1, the second sub-color portion CF2_S of the second color filter layer CFL2, and the third sub-color portion CF3_S of the third color filter layer CFL3. Although Figure 17 Not shown in the text, but as Figure 12 As shown, the sub-color portion CF_S may further include the fourth sub-color portion CF4_S of the first color filter layer CFL1, the fifth sub-color portion CF5_S and the seventh sub-color portion CF7_S of the second color filter layer CFL2, and the sixth sub-color portion CF6_S of the third color filter layer CFL3.

[0246] The sub-color portions CF_S can be arranged to correspond to the sub-emission regions SEA respectively. For example, the first sub-color portion CF1_S can be arranged to overlap with the first sub-emission region SEA1 on the third direction DR3, the second sub-color portion CF2_S can be arranged to overlap with the second sub-emission region SEA2 on the third direction DR3, and the third sub-color portion CF3_S can be arranged to overlap with the third sub-emission region SEA3 on the third direction DR3.

[0247] The sub-color portions CF_S can be arranged to correspond to the sub-apertures OPT_S of the light-blocking layer BM. For example, the first sub-color portion CF1_S can cover the first sub-aperture OPT1_S, the second sub-color portion CF2_S can cover the second sub-aperture OPT2_S, and the third sub-color portion CF3_S can cover the third sub-aperture OPT3_S.

[0248] The width of the sub-color portion CF_S can be greater than the width of the sub-aperture OPT_S of the light-blocking layer BM. For example, in one or more embodiments, the width of the first sub-color portion CF1_S can be greater than the width of the first sub-aperture OPT1_S of the light-blocking layer BM, the width of the second sub-color portion CF2_S can be greater than the width of the second sub-aperture OPT2_S of the light-blocking layer BM, and the width of the third sub-color portion CF3_S can be greater than the width of the third sub-aperture OPT3_S of the light-blocking layer BM.

[0249] In the display device 10 according to this embodiment, such as Figure 18 As illustrated, the transmission window opening OPT_T of the light-blocking layer BM is arranged within the transmission region TA of the sub-display region SDA, such that the lower layer located within the display layer DU may be visually identifiable from the outside. For example, the first passivation layer PAS1 and the first encapsulation layer TFE1 may extend into the transmission region TA, and in this case, the first passivation layer PAS1 and the first encapsulation layer TFE1 may be visually identifiable from the outside through the transmission window opening OPT_T. In one or more embodiments, the first passivation layer PAS1 has a yellowish tint, so that the color of the sub-display region SDA may differ from the color of the main display region MDA.

[0250] Accordingly, in the display device 10 according to this embodiment, in order to minimize or reduce the color difference between the main display area MDA and the sub-display area SDA, the size or area of ​​the third sub-color portion CF3_S and the sixth sub-color portion CF6_S of the blue color filter can be enlarged. Furthermore, the size or area of ​​the first sub-color portion CF1_S and the fourth sub-color portion CF4_S of the red color filter can be enlarged.

[0251] In one or more embodiments, the width of the second overlapping region CBW2 where the second sub-color portion CF2_S overlaps with the light-blocking layer BM can be smaller than the width of the first overlapping region CBW1 where the first sub-color portion CF1_S overlaps with the light-blocking layer BM and the width of the third overlapping region CBW3 where the third sub-color portion CF3_S overlaps with the light-blocking layer BM. For example, by increasing the area covered by the first sub-color portion CF1_S and the third sub-color portion CF3_S in the sub-display area SDA, the color difference between the sub-display area SDA and the main display area MDA, which may occur due to the exposure of the underlying layer caused by the arrangement of the transmission window opening OPT_T, can be minimized or reduced.

[0252] In one or more embodiments, such as Figure 19 As illustrated in the figure, the width of the first overlapping region CBW1 where the first sub-color portion CF1_S overlaps with the light-blocking layer BM can be smaller than the width of the third overlapping region CBW3 where the third sub-color portion CF3_S overlaps with the light-blocking layer BM. In one or more embodiments, the width of the third overlapping region CBW3 where the third sub-color portion CF3_S overlaps with the light-blocking layer BM can be smaller than the width of the first overlapping region CBW1 where the first sub-color portion CF1_S overlaps with the light-blocking layer BM. In this way, by controlling the size of the area where the sub-color portion CF_S overlaps with the light-blocking layer BM for each color, the overall reflected color of the sub-display area SDA can be controlled or selected, and correspondingly, the color difference between the main display area MDA and the sub-display area SDA can be minimized or reduced.

[0253] Figure 20 This illustrates the measurement of a display device according to a comparative example and an embodiment of the present disclosure using a specular component exclusion (SCE) measurement method. A curve graph of the color difference image.

[0254] Apart from Figures 5 to 19 In addition, refer to Figure 20 The sub-color portions CF_S of the display device 10 according to the comparative example can be substantially the same in size or area. For example, the first sub-color portion CF1_S and the fourth sub-color portion CF4_S of the red color filter, the second sub-color portion CF2_S, the fifth sub-color portion CF5_S and the seventh sub-color portion CF7_S of the green color filter, and the third sub-color portion CF3_S and the sixth sub-color portion CF6_S of the blue color filter are the same in size or area. In contrast, in the display device 10 according to one embodiment of the present disclosure, as referenced... Figure 12 As described above, the size or area of ​​the secondary color portion CF_S is different for each color.

[0255] exist Figure 20The curves shown in the figure represent the CIELAB color space. The horizontal axis indicates the color change from red to green and represents the CIELAB color space. The vertical axis of the axis indicates the color change from yellow to blue.

[0256] The target point Target represents the coordinates of the reflected color of the main display area MDA as measured by the SCE measurement method. The comparison point Ref represents the coordinates of the reflected color of the sub-display area SDA of the display device 10 according to the comparison example, as measured by the SCE measurement method. The first point Ex1 represents the coordinates of the reflected color of the sub-display area SDA of the display device 10 according to an embodiment of the present disclosure, as measured by the SCE measurement method.

[0257] The sub-display area SDA of the display device 10 according to the comparative example exhibits a reflective color that is relatively close to yellow and green, while the sub-display area SDA of the display device 10 according to an embodiment of the present disclosure exhibits a reflective color that is substantially close to the reflective color of the main display area MDA.

[0258] In this way, in the display device 10 according to this embodiment, by adjusting the area of ​​the sub-color portion CF_S for each color, the reflected color difference between the main display area MDA and the sub-display area SDA can be minimized or reduced.

[0259] In the following description, one or more embodiments of the display device according to the present disclosure will be described. In the following embodiments, descriptions of components that are the same as those in the embodiments described above (these components are indicated by the same reference numerals) will not be provided or will be simplified, and only the differences will be described substantially.

[0260] Figure 21 This is a layout diagram showing a first color filter layer, a second color filter layer, and a third color filter layer in a sub-display area according to one or more embodiments of the present disclosure. Figure 22 This is a layout diagram showing a first color filter layer in a sub-display area according to one or more embodiments. Figure 23 This is a layout diagram showing a second color filter layer in a sub-display area according to one or more embodiments. Figure 24 This is a layout diagram illustrating a third color filter layer in a sub-display area according to one or more embodiments.

[0261] refer to Figures 21 to 24 The display device 10 according to one or more embodiments and according to reference Figure 12 The display device 10 of one or more embodiments described above differs in that it does not include a light-blocking layer BM.

[0262] For example, the color filter layer CFL may not include (e.g., may exclude) the light-blocking layer BM. For example, the color filter layer CFL may consist only of a first color filter layer CFL1, a second color filter layer CFL2, a third color filter layer CFL3, and an outer coating layer OC.

[0263] The first color filter layer CFL1 may include a first color filter CF1, the second color filter layer CFL2 may include a second color filter CF2, and the third color filter layer CFL3 may include a third color filter CF3. In one or more embodiments, the first color filter CF1 may be a red color filter, the second color filter CF2 may be a green color filter, and the third color filter CF3 may be a blue color filter. The first color filter CF1, the second color filter CF2, and the third color filter CF3 may be included in a color filter CF.

[0264] The first color filter CF1, the second color filter CF2, and the third color filter CF3 can each be arranged throughout the entire display area DA. For example, the first color filter CF1, the second color filter CF2, and the third color filter CF3 can each be arranged throughout the main display area MDA and the sub-display area SDA.

[0265] The first color filter CF1 can cover the first sub-emission area SEA1 and the fourth sub-emission area SEA4. The second color filter CF2 can cover the second sub-emission area SEA2, the fifth sub-emission area SEA5, and the seventh sub-emission area SEA7. The third color filter CF3 can cover the third sub-emission area SEA3 and the sixth sub-emission area SEA6.

[0266] In the display device 10 according to this embodiment, the area where the light-blocking layer BM of the display device 10 according to one or more embodiments is arranged can be implemented in substantially the same manner by forming the overlapping area of ​​the first color filter CF1 of the first color filter layer CFL1, the second color filter CF2 of the second color filter layer CFL2, and the third color filter CF3 of the third color filter layer CFL3. For example, in the overlapping area of ​​the first color filter CF1, the second color filter CF2, and the third color filter CF3, light emitted from the light-emitting element ED can be blocked.

[0267] The first color filter CF1 may include a first sub-color aperture ROPT_S. The second color filter CF2 may include a second sub-color aperture GOPT_S. The third color filter CF3 may include a third sub-color aperture BOPT_S. The first sub-color aperture ROPT_S, the second sub-color aperture GOPT_S, and the third sub-color aperture BOPT_S may be included in a sub-color aperture WOPT_S.

[0268] The first sub-color aperture ROPT_S can overlap with the second sub-emission area SEA2, the third sub-emission area SEA3, the fifth sub-emission area SEA5, the sixth sub-emission area SEA6, and the seventh sub-emission area SEA7. The second sub-color aperture GOPT_S can overlap with the first sub-emission area SEA1, the third sub-emission area SEA3, the fourth sub-emission area SEA4, and the sixth sub-emission area SEA6. The third sub-color aperture BOPT_S can overlap with the first sub-emission area SEA1, the second sub-emission area SEA2, the fourth sub-emission area SEA4, the fifth sub-emission area SEA5, and the seventh sub-emission area SEA7.

[0269] In the first sub-diagonal column SC1, the first sub-color opening ROPT_S and the second sub-color opening GOPT_S can be alternately arranged to be spaced apart and / or separated from each other in the fourth direction DR4 (e.g., spaced apart or separated). In the second sub-diagonal column SC2, the second sub-color opening GOPT_S and the third sub-color opening BOPT_S can be alternately arranged to be spaced apart and / or separated from each other in the fifth direction DR5 (e.g., spaced apart or separated).

[0270] The planar area of ​​each of the multiple sub-color openings WOPT_S can be greater than the planar area of ​​the corresponding sub-emission region SEA. For example, the planar area of ​​the first sub-color opening ROPT_S can be greater than the planar areas of the second sub-emission region SEA2, the third sub-emission region SEA3, the fifth sub-emission region SEA5, the sixth sub-emission region SEA6, and the seventh sub-emission region SEA7; the planar area of ​​the second sub-color opening GOPT_S can be greater than the planar areas of the first sub-emission region SEA1, the third sub-emission region SEA3, the fourth sub-emission region SEA4, and the sixth sub-emission region SEA6; and the planar area of ​​the third sub-color opening BOPT_S can be greater than the planar areas of the first sub-emission region SEA1, the second sub-emission region SEA2, the fourth sub-emission region SEA4, the fifth sub-emission region SEA5, and the seventh sub-emission region SEA7.

[0271] The first color filter CF1 may include a first color transmission window opening ROPT_T disposed in the sub-display area SDA and arranged between a plurality of first sub-color openings ROPT_S; the second color filter CF2 may include a second color transmission window opening GOPT_T disposed in the sub-display area SDA and arranged between a plurality of second sub-color openings GOPT_S; and the third color filter CF3 may include a third color transmission window opening BOPT_T disposed in the sub-display area SDA and arranged between a plurality of third sub-color openings BOPT_S. The first color transmission window opening ROPT_T, the second color transmission window opening GOPT_T, and the third color transmission window opening BOPT_T may be included in a color transmission window opening WOPT_T.

[0272] The first color transmission window opening ROPT_T, the second color transmission window opening GOPT_T, and the third color transmission window opening BOPT_T can each be arranged in the transmission region TA. The first color transmission window opening ROPT_T, the second color transmission window opening GOPT_T, and the third color transmission window opening BOPT_T can completely overlap on the third direction DR3. The first color transmission window opening ROPT_T, the second color transmission window opening GOPT_T, and the third color transmission window opening BOPT_T can form a single color transmission window opening WOPT_T.

[0273] In the display device 10 according to this embodiment, the size or area of ​​the second sub-color aperture GOPT_S can be larger than the size or area of ​​the first sub-color aperture ROPT_S and the third sub-color aperture BOPT_S. For example, as Figures 22 to 24 As shown in the diagram, the size or area of ​​the second sub-color opening GOPT_S, which overlaps with the third sub-emission region SEA3 and the sixth sub-emission region SEA6, can be larger than the size or area of ​​the first sub-color opening ROPT_S and the third sub-color opening BOPT_S.

[0274] As described above, in order to minimize or reduce the color difference between the main display area MDA and the sub-display area SDA, the size or area of ​​the second sub-color aperture GOPT_S is formed to be larger than the size or area of ​​the first sub-color aperture ROPT_S and the third sub-color aperture BOPT_S. This allows the amount of light reflected by the second sub-color aperture GOPT_S to be reduced and the amount of light reflected by the first sub-color aperture ROPT_S and the third sub-color aperture BOPT_S to be increased. Accordingly, the color difference between the main display area MDA and the sub-display area SDA can be minimized or reduced.

[0275] Although the accompanying drawings illustrate an embodiment in which the size or area of ​​the second sub-color opening GOPT_S overlapping with the third sub-emission region SEA3 and the sixth sub-emission region SEA6 is enlarged, the embodiments of this disclosure are not limited thereto. For example, in one or more embodiments, the size or area of ​​the second sub-color opening GOPT_S overlapping with the first sub-emission region SEA1 and the fourth sub-emission region SEA4 may be enlarged.

[0276] For example, if it is desired or suitable to reduce the green color and increase the blue color (e.g., when it is desired or suitable to reduce the green color and increase the blue color), as in the former case, the size or area of ​​the second sub-color opening GOPT_S that overlaps with the third sub-emission region SEA3 and the sixth sub-emission region SEA6 can be enlarged; or if it is desired or suitable to reduce the green color and increase the red color (e.g., when it is desired or suitable to reduce the green color and increase the red color), as in the latter case, the size or area of ​​the second sub-color opening GOPT_S that overlaps with the first sub-emission region SEA1 and the fourth sub-emission region SEA4 can be enlarged.

Figure 26 According to one or more embodiments along Figure 21 The cross-sectional view taken from line X7-X7' in the diagram. Figure 27 This illustrates the measurement of a display device according to a comparative example and another embodiment of the present disclosure by the SCE measurement method. A curve graph of the color difference image.

[0278] Apart from Figures 21 to 24 In addition, refer to Figure 25 and Figure 26 The sub-display area SDA may include a black blocking area CWA, a red transmissive area CRA, a green transmissive area CGA, a blue transmissive area CBA, a red blocking area, a green blocking area RBA, and a blue blocking area.

[0279] The black blocking region CWA can be the area where the first color filter CF1, the second color filter CF2, and the third color filter CF3 all overlap on the third direction DR3. Within the black blocking region CWA, all light emitted from the sub-emission region SEA can be blocked.

[0280] The red transmission area CRA can be an area with only the first color filter CF1, and can be an area without the second color filter CF2 and the third color filter CF3. The green transmission area CGA can be an area with only the second color filter CF2, and can be an area without the first color filter CF1 and the third color filter CF3. The blue transmission area CBA can be an area with only the third color filter CF3, and can be an area without the first color filter CF1 and the second color filter CF2.

[0281] The red blocking area is the region where only the first color filter CF1 is not placed, and it can also be the region where the second color filter CF2 and the third color filter CF3 overlap on the third direction DR3. The green blocking area RBA is the region where only the second color filter CF2 is not placed, and it can also be the region where the first color filter CF1 and the third color filter CF3 overlap on the third direction DR3. The blue blocking area is the region where only the third color filter CF3 is not placed, and it can also be the region where the first color filter CF1 and the second color filter CF2 overlap on the third direction DR3.

[0282] The display device 10 according to this embodiment does not include a light-blocking layer BM, but includes a black blocking region CWA in which the first color filter CF1, the second color filter CF2 and the third color filter CF3 overlap, thereby achieving the same function as the light-blocking layer BM.

[0283] Meanwhile, in the display device 10 according to this embodiment, the red transmission region CRA overlaps with the first sub-emission region SEA1 and the fourth sub-emission region SEA4, the green transmission region CGA overlaps with the second sub-emission region SEA2, the fifth sub-emission region SEA5 and the seventh sub-emission region SEA7, and the blue transmission region CBA overlaps with the third sub-emission region SEA3 and the sixth sub-emission region SEA6, thereby improving color reproduction and color purity.

[0284] Furthermore, the display device 10 according to this embodiment includes a red blocking region, a green blocking region RBA, and a blue blocking region, thereby allowing adjustment of the reflected color of the sub-display region SDA. For example, as described above, due to the unique color of the underlying layer exposed in the transmissive region TA of the sub-display region SDA, a reflected color difference may occur between the main display region MDA and the sub-display region SDA. To minimize or reduce this color difference, in the display device 10 according to this embodiment, the areas of the red blocking region, the green blocking region RBA, and the blue blocking region can be adjusted independently.

[0285] In one or more embodiments, in order to counteract the yellowish tint from the first passivation layer PAS1 (see...) Figure 18The color of the reflected yellow light can increase the area of ​​the green blocking region RBA near the blue transmission region CBA, such as... Figure 25 and Figure 26 As shown in the diagram. In this case, the color difference between the main display area MDA and the secondary display area SDA can be minimized or reduced.

[0286] For example, such as Figure 27 As shown in the figure, the second point Ex2, which represents the coordinates of the reflected color of the sub-display area SDA of the display device 10 according to this embodiment, measured by the SCE measurement method, can be close to the target point Target, which represents the coordinates of the reflected color of the main display area MDA, measured by the SCE measurement method.

[0287] According to the comparison example, the sub-display area SDA of the display device 10 exhibits a reflective color that is relatively close to yellow and green, similar to comparison point Ref, while the sub-display area SDA of the display device 10 according to this embodiment exhibits a reflective color that is substantially close to the reflective color of the main display area MDA, similar to the second point Ex2.

[0288] In this way, in the display device 10 according to this embodiment, by adjusting the area of ​​the sub-color opening WOPT_S for each color, the reflected color difference between the main display area MDA and the sub-display area SDA can be minimized or reduced.

[0289] Figure 28A This is a plan view illustrating a sub-display area of ​​a display device according to one or more embodiments of the present disclosure. Figure 28B According to one or more embodiments along Figure 28A The cross-sectional view taken by line X8-X8'.

[0290] Apart from Figures 12 to 19 In addition, refer to Figure 28A and Figure 28B The display device 10 according to one or more embodiments and according to reference Figure 18 The display device 10 of one or more embodiments described above differs in that a secondary color portion CF_S is also arranged in the transmissive region TA.

[0291] For example, the display device 10 according to this embodiment may include a light-blocking layer BM, a first color filter layer CFL1, a second color filter layer CFL2, and a third color filter layer CFL3, similar to that according to the reference. Figure 12 The display device 10 of one or more embodiments described above. Furthermore, similar to those described in reference illustrative materials... Figure 12The display device 10 of one or more embodiments described above includes a red color filter whose first sub-color portion CF1_S and fourth sub-color portion CF4_S can overlap with the first sub-emission area SEA1 and the fourth sub-emission area SEA4, respectively; a green color filter whose second sub-color portion CF2_S, fifth sub-color portion CF5_S and seventh sub-color portion CF7_S can overlap with the second sub-emission area SEA2, fifth sub-emission area SEA5 and seventh sub-emission area SEA7, respectively; and a blue color filter whose third sub-color portion CF3_S and sixth sub-color portion CF6_S can overlap with the third sub-emission area SEA3 and the sixth sub-emission area SEA6, respectively.

[0292] However, the display device 10 according to this embodiment and the reference 10 Figure 12 The display device 10 of one or more embodiments described above differs in that the size of the sub-color portion CF_S is substantially the same as the size of the sub-opening OPT_S.

[0293] For example, according to the reference Figure 12 In the display device 10 of one or more embodiments described, the size or area of ​​some of the sub-color portions CF_S is enlarged to cover the top surface of the light-blocking layer BM. However, in the display device 10 according to this embodiment, most of the sub-color portions CF_S can be arranged to overlap only with the sub-opening OPT_S. In other words, in some embodiments (such as...) Figure 12 In the embodiment shown, the sub-color portions CF_S are made large enough to cover the entire top surface of the light-blocking layer BM. In other embodiments, most of the sub-color portions CF_S are positioned such that they only cover the sub-aperture OPT_S, without covering the entire top surface of the light-blocking layer BM. For example, in one or more embodiments, each of the sub-color portions CF_S may be arranged to overlap only with its corresponding sub-aperture OPT_S (e.g., limited by the sub-aperture, rather than expanding the sub-color portion to cover a larger area).

[0294] However, cases where the size of the secondary color portion CF_S is substantially the same as the size of the secondary opening OPT_S (i.e., the corresponding secondary opening OPT_S) include the following situations: the width of the secondary color portion CF_S is substantially the same as the width of the secondary opening OPT_S, but both ends of the secondary color portion CF_S (e.g., simultaneously) cover a portion of the top surface of the light-blocking layer BM, such as... Figure 28A and Figure 28BAs illustrated in the figure. For example, it includes a case where the secondary color portion CF_S does not cover most of the top surface of the light-blocking layer BM, but only slightly covers the top surface of the light-blocking layer BM at both ends adjacent to the secondary opening OPT_S (e.g., simultaneously). Here, the width of the secondary color portion CF_S covering the top surface of the light-blocking layer BM in the cross-sectional view can be less than 10% of the width of the light-blocking layer BM.

[0295] In the display device 10 according to one or more embodiments, the reflected color is improved by expanding the area of ​​the sub-color portion CF_S to the top surface of the light-blocking layer BM. In the display device 10 according to this embodiment, the reflected color can be improved by further providing the sub-color portion CF_S in the transmissive region TA.

[0296] For example, the display device 10 according to this embodiment may further include a sub-color portion CF_S arranged in the transmissive region TA. For example, as Figure 28A and Figure 28B As shown in the diagram, the third sub-color portion CF3_S can be further arranged in the transmission window opening OPT_T of the transmission region TA.

[0297] As described above, due to the exposure of the unique color of the underlying layer caused by the arrangement of the transmissive region TA, a color difference may occur between the sub-display region SDA and the main display region MDA. However, this color difference can be minimized or reduced by setting the sub-color portion CF_S in the transmissive region TA.

[0298] Although the accompanying drawings illustrate a third sub-color portion CF3_S arranged in the transmission region TA, embodiments of this disclosure are not limited thereto. Depending on the unique color of the underlying layer, in one or more embodiments, a first sub-color portion CF1_S or a second sub-color portion CF2_S may be arranged in the transmission region TA. In one or more embodiments, two or more types (categories) of sub-color portions CF_S selected from the first sub-color portion CF1_S, the second sub-color portion CF2_S, and the third sub-color portion CF3_S may be arranged to overlap each other.

[0299] In one or more embodiments, to prevent optical devices 500 (see [reference]) from incident in the transmission region TA Figure 3The amount of light emitted is reduced, and the thickness TH_C of the sub-color portion CF_S arranged in the transmission region TA can be less than the thickness of the sub-color portion CF_S overlapping with the sub-emission region SEA. In one or more embodiments, the thickness TH_C of the sub-color portion CF_S arranged in the transmission region TA can be approximately 1 / 30 to 1 / 2 of the thickness of the sub-color portion CF_S overlapping with the sub-emission region SEA. For example, in one or more embodiments, the thickness of the sub-color portion CF_S overlapping with the sub-emission region SEA can be approximately 0.1 micrometers (μm) to 1.5 μm.

[0300] exist Figure 28A and Figure 28B The example described below includes a light-blocking layer BM, as shown in the reference. Figure 12 As described in one or more embodiments of the display device 10, the present disclosure is not limited thereto. For example, the display device 10 according to one or more embodiments may not include (e.g., may exclude) the light-blocking layer BM, as described in reference 10. Figure 21 As in the display device 10 of one or more embodiments described above.

[0301] In this regard, at least one of the first color transmission window opening ROPT_T, the second color transmission window opening GOPT_T, and the third color transmission window opening BOPT_T may not be arranged in the transmission region TA. For example, at least one of the first color filter CF1, the second color filter CF2, and the third color filter CF3 may cover the transmission region TA. For example, if the third color transmission window opening BOPT_T is not arranged in the transmission region TA (e.g., when the third color transmission window opening BOPT_T is not arranged in the transmission region TA), the third color filter CF3 may cover the transmission region TA and may be displayed in Figure 28B The third sub-color portion CF3_S is arranged in the transmission region TA (e.g., when...). Figure 28B The same effect is obtained when the third sub-color portion CF3_S is placed in the transmission region TA.
