[0001] This application claims the benefit and priority of Korean Patent Application No. 10-2024-0197743, filed in Korea on December 26, 2024, the entire contents of which are incorporated herein by reference for all purposes. Technical Field

[0002] This invention relates to a light-emitting display device. Background Technology

[0003] With the advancement of the information age, the demand for display devices for displaying images has grown in various forms. As a result, various types of display devices have recently been used, such as liquid crystal displays (LCDs), organic light-emitting displays (OLEDs), micro light-emitting diode (LED) displays, and quantum dot displays (QDs).

[0004] In display devices, organic light-emitting display devices are self-emissive. In an organic light-emitting display device, holes and electrons are injected into the emitting layer from an anode electrode for hole injection and a cathode electrode for electron injection, and the injected holes and electrons combine with each other. The combined holes and electrons then transition from the excited state to the ground state, allowing the organic light-emitting display device to emit light and display images.

[0005] This type of organic light-emitting display device primarily uses polarizers on the display surface of the panel to reduce external light reflection. However, when an organic light-emitting display device uses polarizers, the transmittance decreases, thereby reducing panel efficiency and increasing power consumption. Summary of the Invention

[0039] Throughout the accompanying drawings and detailed description, unless otherwise described, the same reference numerals should be understood to refer to the same elements, features, and structures. For clarity, illustration, and / or convenience, the dimensions, lengths, and thicknesses of layers, regions, and elements, and their depiction, may be exaggerated. Detailed Implementation

[0040] The advantages and features of this disclosure and its implementation have been illustrated by referring to the embodiments described herein. However, this disclosure may be implemented in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are exemplary and provided to make this disclosure thorough and complete to aid those skilled in the art in understanding the inventive concept, without limiting the scope of protection of this disclosure.

[0041] The shapes (e.g., dimensions, lengths, widths, heights, thicknesses, positions, radii, diameters, and areas), sizes, ratios, angles, quantities, etc., disclosed herein (including those shown in the accompanying drawings) are merely examples, and therefore, this disclosure is not limited to the details shown. Any implementation described herein as an "example" is not necessarily to be construed as superior to or having an advantage over other implementations. However, it should be noted that the relative dimensions of the components shown in the accompanying drawings are part of this disclosure.

[0042] When terms such as “comprising,” “having,” “including,” “containing,” “constituting,” “made of,” “formed from,” etc., are used with respect to one or more elements, one or more other elements may be added unless terms such as “only” are used. The terminology used in this disclosure is for describing exemplary embodiments only and is not intended to limit the scope of this disclosure. Unless the context clearly indicates otherwise, singular terms may include plural forms.

[0043] When constructing components, the components are interpreted as including error regions, although they are not explicitly described.

[0044] When describing positional relationships, for example, when the positional order is described as "above", "over", "below", "below", and "next to", it can include cases where there is no contact between them, unless "only" or "directly" is used.

[0045] When it is mentioned that the first element is positioned "on" the second element, it does not mean in the figure that the first element is substantially above the second element. The upper and lower parts of the object involved can vary depending on the orientation of the object. Therefore, the case of the first element being positioned "on" the second element includes the case where the first element is positioned "below" the second element as well as the case where the first element is positioned "above" the second element in the figure or in the actual configuration.

[0046] When describing temporal relationships, such as when time sequence is described as “after,” “following,” “before,” and “after,” discontinuous cases can be included unless “only” or “directly” is used.

[0047] It should be understood that although the terms "first," "second," etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

[0048] In describing the elements of this disclosure, the terms “first,” “second,” “A,” “B,” “(a),” “(b),” etc., may be used. These terms are intended to identify one or more corresponding elements from one or more other elements, and are not used to define the nature, basis, order, or number of elements.

[0049] Unless otherwise stated, when describing a component as “connected,” “joined,” “attached,” “adhesive,” etc., to another component, the component may be directly connected, joined, attached, or adhered to another component, or indirectly connected, joined, attached, or adhered to another component, wherein one or more intermediary components are disposed or inserted between these components.

[0050] Unless otherwise stated, when describing an element as "in contact" or "overlapping" with another element, the element may not only be in direct contact or overlap with another element, but also may be indirect contact or overlap with another element, wherein one or more intermediary elements are disposed or inserted between these elements.

[0051] The term "at least one" should be understood to include any and all combinations of one or more of the associated listed items. For example, "at least one of the first element, the second element, and the third element" can include all combinations of two or more elements selected from the first element, the second element, and the third element, as well as each of the first element, the second element, and the third element.

[0052] Features of the various embodiments of this disclosure may be partially or wholly linked or combined with each other, may be technically related to each other, and may operate differently, be linked, or drive together. Embodiments of this disclosure may be implemented or performed independently of each other, or may be implemented or performed together in a mutually dependent or related relationship. In one or more aspects, components of each device according to the various embodiments of this disclosure are operatively coupled and configured.

[0053] In the following description, various exemplary embodiments of the present disclosure are described in detail with reference to the accompanying drawings. Regarding the reference numerals for elements in each drawing, the same elements may be shown in other drawings, and unless otherwise stated, the same reference numerals may refer to the same elements. The same or similar elements may be represented by the same reference numerals, even if they are shown in different drawings. Furthermore, for ease of description, the scale, dimensions, size, and thickness of each element shown in the drawings may differ from the actual scale, dimensions, size, and thickness; therefore, embodiments of the present disclosure are not limited to the scale, dimensions, size, and thickness shown in the drawings.

[0054] Figure 1 A light-emitting display device according to an embodiment of the present disclosure is shown.

[0055] In the following text, the X-axis represents the direction parallel to the scan line (or gate line), the Y-axis represents the direction parallel to the data line, and the Z-axis represents the height direction of the light-emitting display device. The X-axis may intersect the Y-axis, and the Z-axis may be perpendicular to the X-axis and Y-axis. For example, the X-axis, Y-axis, and Z-axis may be perpendicular to each other.

[0056] The light-emitting display device according to the embodiments of this disclosure is implemented as an organic light-emitting display device, but it can also be implemented as a liquid crystal display device, a quantum dot light-emitting diode display device, or an electrophoretic display device.

[0057] refer to Figure 1 The light-emitting display device according to the embodiments of the present disclosure may include a display panel 110, a scan driver 120 (or gate driver) embedded in the display panel 110, a data driver 130 connected to the display panel 110, a timing controller 160 for controlling the scan driver 120 and the data driver 130, and a power supply circuit 170.

[0058] Display panel 110 includes a display area DA and a non-display area NDA surrounding the display area DA. Display panel 110 includes pixels P disposed in the display area DA to display images. Each pixel P may include multiple subpixels SP. The structure of the subpixels SP can vary depending on the type of light-emitting display device. For example, depending on the structure, subpixels SP can be formed as a top-emitting type, a bottom-emitting type, or a dual-emitting type. Subpixels SP indicate units capable of forming a specific type of color filter or capable of emitting their own color without forming a color filter. Depending on the light-emitting characteristics, subpixels SP may have one or more other emitting areas. For example, multiple subpixels SP can be arranged in a strip or quad type, but embodiments of this disclosure are not limited thereto. The color type, arrangement type, arrangement order, etc., of the subpixels SP can be configured in various forms depending on the light-emitting characteristics, device lifespan, device specifications, etc.

[0059] Display panel 110 may include data lines DL and scan lines SL (or gate lines) connected to sub-pixels SP. Data lines DL may be arranged to intersect with scan lines SL. Each sub-pixel SP of display panel 110 may be connected to any one of the data lines DL and any one of the scan lines SL. Data lines DL may provide data voltage from data driver 130 to each sub-pixel SP. Scan lines SL may provide scan signals from scan driver 120 to each sub-pixel SP.

[0060] Each of the sub-pixels SP is turned on by the scan signal. When the data voltage of the data line DL is supplied to the gate electrode of the driving transistor, the light-emitting element can emit light according to the drain-to-source current of the driving transistor. The scan driver 120 can receive the scan control signal GCS from the timing controller 160. The scan driver 120 can provide a scan signal or a transmit control signal to the scan line SL by using the scan control signal GCS.

[0061] The scan driver 120 can be configured in the non-display area NDA outside one or both sides of the display area DA in a gate-in-panel (GIP) manner. Alternatively, the scan driver 120 can be fabricated as a driver chip, mounted on a flexible film, and attached to the non-display area NDA outside one or both sides of the display area DA in a tape auto-bonding (TAB) manner.

[0062] Data driver 130 can receive digital video data DATA and data control signal DCS from timing controller 160. Data driver 130 converts digital video data DATA into analog positive / negative data voltages using data control signal DCS and provides the analog positive / negative data voltages to data line DL.

[0063] The timing controller 160 receives digital video data DATA and timing signals from the host system. The timing signals may include a vertical sync signal, a horizontal sync signal, a data enable signal, and a dot clock. The vertical sync signal defines one frame period. The horizontal sync signal defines one horizontal period required to provide data voltage to the pixels of a horizontal line on the display panel 110. The data enable signal defines the period of valid input data. The dot clock is a signal that repeats with a predetermined short period.

[0064] The timing controller 160 can generate a data control signal (DCS) for controlling the operating timing of the data driver 130 and a scan control signal (GCS) for controlling the operating timing of the scan driver 120 based on the timing signal. The timing controller 160 can output the scan control signal (GCS) to the scan driver 120 to control the scan driver 120, and output digital video data (DATA) and the data control signal (DCS) to the data driver 130 to control the data driver 130.

[0065] The power supply circuit 170 can generate and provide multiple drive voltages required for the operation of all circuit configurations of the light-emitting display device by using an input voltage. The power supply circuit 170 can generate a first power supply voltage EVDD (or pixel power supply voltage), a second power supply voltage EVSS (or common power supply voltage), and an initialization voltage Vref (or reference voltage), and supply the generated voltages to the display panel 110. The power supply circuit 170 can generate and provide various drive voltages required for the operation of the scan driver 120, the data driver 130, and the timing controller 160.

[0066] Figure 2 This is a circuit diagram illustrating a sub-pixel of a light-emitting display device according to an embodiment of the present disclosure.

[0067] refer to Figure 2 Each pixel P comprises multiple sub-pixels SP that constitute a unit pixel. Each of the multiple sub-pixels SP contains a pixel circuit having a 3T (transistor) 1C (capacitor) and a light-emitting device ED (wherein the 3T (transistor) 1C (capacitor) includes a driving transistor DR, a first switching transistor TR1, a second switching transistor TR2, and a storage capacitor Cst), but is not limited thereto. Each sub-pixel SP may also include a compensation circuit. In this case, the sub-pixel SP can have various structures such as 3T2C, 4T1C, 4T2C, 5T1C, 5T2C, 6T1C, 6T2C, 7T1C, and 7T2C.

[0068] At least one thin-film transistor DR, TR1, and TR2 in each sub-pixel SP may include a gate electrode, a source electrode, and a drain electrode. Since the source and drain electrodes can change according to the direction of the voltage and current applied to the gate electrode, rather than being fixed, either the source or drain electrode can be represented as a first electrode, and the other as a second electrode. At least one transistor DR, TR1, and TR2 may be made of at least one of polycrystalline silicon, amorphous silicon, and oxide semiconductors. Transistors DR, TR1, and TR2 may be P-type or N-type, or P-type and N-type may be used interchangeably.

[0069] The driving transistor DR corresponds to the transistor used to drive the light-emitting device ED, and the driving transistor DR includes a first node N1 to which a data voltage Vdata is applied, a second node N2 connected to the pixel electrode (first electrode or anode electrode) of the light-emitting device ED, and a third node N3 connected to the first power line VDDL (or pixel power line) and supplied with a first power supply voltage EVDD (or pixel power voltage). For example, the driving transistor DR can generate a data current based on the first power supply voltage EVDD provided from the first power line VDDL, and can provide the data current to the first electrode of the light-emitting device ED.

[0070] The first switching transistor TR1 can be used to supply the data voltage Vdata from the data line DL to the first node N1 of the driving transistor DR. The second switching transistor TR2 can be used to supply the reference voltage Vref from the reference line REFL to the second node N2 of the driving transistor DR, or it can output the voltage of the second node N2 of the driving transistor DR. A storage capacitor Cst can be connected between the first node N1 and the second node N2 of the driving transistor DR. The storage capacitor Cst can be used to maintain the data voltage Vdata supplied to the driving transistor DR for one frame, but the embodiments of this disclosure are not limited thereto.

[0071] The light-emitting device (ED) may include a pixel electrode (first electrode or anode electrode) connected to a second node N2 of a driving transistor DR, and a common electrode (second electrode or cathode electrode) connected to a second power line VSSL. The ED can emit light through an emission layer (or organic emission layer) between the first and second electrodes in response to a drive current generated by the driving transistor DR. The pixel electrode of the ED may be an independent electrode for each light-emitting device, and the common electrode and emission layer of the ED may be a common layer shared by the entire light-emitting device; however, embodiments of this disclosure are not limited thereto.

[0072] Figure 3 The pixel structure of a light-emitting display device according to an embodiment of the present disclosure is shown. Figure 4 A dam and a color filter for a pixel are shown according to an embodiment of the present disclosure. Figure 5 It is according to the embodiments of this disclosure along Figure 4 A cross-sectional view taken from line I-I'.

[0073] refer to Figures 3 to 5 The light-emitting display device according to embodiments of the present disclosure may include a pixel P, a data line DL, a scan line SL (or a gate line), a first power line VDDL, pixel circuits CA1, CA2, CA3 and CA4, at least one color filter CF1, CF3 and CF4, and a dam BA.

[0074] Pixel P may include multiple sub-pixels SP1, SP2, SP3, and SP4. These sub-pixels SP1, SP2, SP3, and SP4 may include first to fourth sub-pixels SP1, SP2, SP3, and SP4. The first to fourth sub-pixels SP1, SP2, SP3, and SP4 may be arranged along a first direction (or the X-axis direction) or a second direction (or the Y-axis direction). For example, the first to fourth sub-pixels SP1, SP2, SP3, and SP4 may be arranged adjacent to each other in the first direction (or the X-axis direction). The first to fourth sub-pixels SP1, SP2, SP3, and SP4 may include emitting regions EA1, EA2, EA3, and EA4 that emit light, and a non-emitting region NEA.

[0075] Emitting regions EA1, EA2, EA3, and EA4 may correspond to the areas in pixel P that emit light. Emitting regions EA1, EA2, EA3, and EA4 may include first to fourth emitting regions EA1, EA2, EA3, and EA4 that emit light of different colors. For example, the first to fourth emitting regions EA1, EA2, EA3, and EA4 may overlap with the opening OA of the pixel electrode AE ​​(first electrode or anode electrode) defined by the embankment BA.

[0076] The first to fourth emission regions EA1, EA2, EA3, and EA4 may overlap with at least one color filter CF1, CF3, and CF4 corresponding to the first to fourth sub-pixels SP1, SP2, SP3, and SP4. For example, the first to fourth emission regions EA1, EA2, EA3, and EA4 may overlap with the opening region OA of the pixel electrode AE ​​and at least one color filter CF1, CF3, and CF4.

[0077] The first to fourth emission regions EA1, EA2, EA3, and EA4 can emit light of different colors through at least one color filter CF1, CF3, and CF4. For example, at least one color filter CF1, CF3, and CF4 can emit light of different colors. For example, at least one color filter CF1, CF3, and CF4 can be formed of an organic material that transmits light of different colors. At least one color filter CF1, CF3, and CF4 may include a first color filter CF1 that transmits red light, a third color filter CF3 that transmits blue light, and a fourth color filter CF4 that transmits green light. For example, the first emission region EA1 of the first sub-pixel SP1 can emit red light through the first color filter CF1, the second emission region EA2 of the second sub-pixel SP2 may not have a color filter and can emit white light, the third emission region EA3 of the third sub-pixel SP3 can emit blue light through the third color filter CF3, and the fourth emission region EA4 of the fourth sub-pixel SP4 can emit green light through the fourth color filter CF4, but the embodiments of this disclosure are not limited thereto.

[0078] The non-emitting area (NEA) may include data lines DL, scan lines SL (or gate lines), a first power line VDDL, and pixel circuits CA1, CA2, CA3, and CA4. The NEA may overlap with the embankment BA. For example, the NEA may be the area other than the first to fourth emitting areas EA1, EA2, EA3, and EA4 of the first to fourth sub-pixels SP1, SP2, SP3, and SP4.

[0079] A scan line SL extending along a first direction (or the X-axis direction) can be disposed in the non-emitting area NEA, and a data line DL and a first power line VDDL extending along a second direction (or the Y-axis direction) intersecting the first direction can be disposed in the non-emitting area NEA. Furthermore, a second power line VSSL extending along the second direction can be disposed in the non-emitting area NEA, but embodiments of this disclosure are not limited thereto.

[0080] The pixel circuits CA1, CA2, CA3, and CA4 corresponding to each of sub-pixels SP1, SP2, SP3, and SP4 can be set in the non-emitting region NEA. For example, as Figure 2 As shown, each of the pixel circuits CA1, CA2, CA3, and CA4 may include at least one thin-film transistor DR, TR1, and TR2, and a storage capacitor Cst. At least one thin-film transistor DR, TR1, and TR2 may include a driving transistor DR, a first switching transistor TR1, and a second switching transistor TR2, but embodiments of this disclosure are not limited thereto.

[0081] refer to Figure 5 The light-emitting display device according to the embodiments of the present disclosure may include a substrate 111, a data line DL, a first power line VDDL, a buffer layer BF, a passivation layer PAS, at least one color filter CF1, CF3 and CF4, a planarization layer OC, a pixel electrode AE, an organic emitting layer EL, a common electrode CE and a dam BA.

[0082] At least some of at least one signal line may be provided on the substrate 111. For example, a data line DL and a first power line VDDL may be provided on the substrate 111. Furthermore, a reference line REFL and a second power line VSSL may be provided on the substrate 111, but the embodiments of this disclosure are not limited thereto. For example, at least one signal line provided at the bottommost portion of the substrate 111 may be formed of the same material in the same layer as the light-shielding layer provided in the pixel circuits CA1, CA2, CA3, and CA4. For example, the light-shielding layer may serve to block external light from incident on the active layer of the thin-film transistor. For example, the light-shielding layer may be used to block external light incident on the active layer of the thin-film transistor. The light-shielding layer may be formed of any one or more of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or an alloy thereof, in single or multiple layers.

[0083] A buffer layer BF can be disposed on a substrate 111. The buffer layer BF can be configured to cover at least one signal line and a light-shielding layer disposed on the substrate 111. At least one protective layer and at least one thin-film transistor can be disposed on the buffer layer BF. For example, the at least one protective layer may include a passivation layer PAS. The passivation layer PAS can be formed of a single layer or multiple layers, which may include silicon oxide (SiO2). X Silicon nitride (SiN) X Inorganic insulating materials such as aluminum oxide (Al2O3) or aluminum oxide (Al2O3).

[0084] At least one color filter CF1, CF3, and CF4 can be disposed on the passivation layer PAS. At least one color filter CF1, CF3, and CF4 can be configured to correspond to the first sub-pixel SP1, the third sub-pixel SP3, and the fourth sub-pixel SP4 among the first to fourth sub-pixels SP1, SP2, SP3, and SP4. No color filter may be disposed in the second sub-pixel SP2 among the first to fourth sub-pixels SP1, SP2, SP3, and SP4. For example, a first color filter CF1, which converts white light emitted from the organic emission layer EL to red, can be disposed in the first emission area EA1 of the first sub-pixel SP1. The second emission area EA2 of the second sub-pixel SP2 can emit white light because it has no color filter. A third color filter CF3, which converts white light emitted from the organic emission layer EL to blue, can be disposed in the third emission area EA3 of the third sub-pixel SP3. A fourth color filter CF4, which converts white light emitted from the organic emission layer EL to green, can be disposed in the fourth emission area EA4 of the fourth sub-pixel SP4.

[0085] A planarization layer OC (or capping layer) may be disposed on a passivation layer PAS and at least one color filter CF1, CF3, and CF4. The planarization layer OC can planarize the step differences caused by at least one signal line, at least one thin-film transistor, and at least one color filter CF1, CF3, and CF4 disposed on the substrate 111, and may be formed of an organic insulating material. For example, the planarization layer OC may be formed of organic materials such as acrylic resin, epoxy resin, phenolic resin, polyamide resin, or polyimide resin, but embodiments of this disclosure are not limited thereto.

[0086] The pixel electrode AE ​​(first electrode or anode electrode), organic emission layer EL, common electrode CE (second electrode or cathode electrode), and embankment BA constituting the light-emitting device ED can be disposed on the planarization layer OC.

[0087] Pixel electrodes AE can be disposed on a planarization layer OC. Pixel electrodes AE can be patterned and disposed on the planarization layer OC for each sub-pixel SP1, SP2, SP3, and SP4. Pixel electrodes AE can be formed of a transparent or semi-transparent metallic material. For example, pixel electrodes AE can be formed of a transparent conductive material TCO that transmits light, such as indium tin oxide (ITO) or indium zinc oxide (IZO). Pixel electrodes AE can also be formed of a semi-transparent conductive material such as magnesium (Mg), silver (Ag), or an alloy of magnesium (Mg) and silver (Ag). For example, pixel electrodes AE formed of semi-transparent metallic materials can improve light extraction efficiency through microcavities. Pixel electrodes AE can be the anode electrode of a light-emitting element ED. According to embodiments of this disclosure, pixel electrodes AE may also include a low-reflection metallic layer. For example, the low-reflection metallic layer may include a metal oxide or an alloy oxide. For example, the low-reflection metallic layer may include copper oxide (CuOx), nickel oxide (NiOx), molybdenum oxide (MoOx), or tungsten oxide (WOx), but embodiments of this disclosure are not limited thereto.

[0088] A dam BA can be disposed on the pixel electrode AE ​​and the planarization layer OC. The dam BA can be disposed on the planarization layer OC to cover a portion of the edge of the pixel electrode AE. That is, the dam BA can have a main body portion (which may also be referred to as the "first sub-part") extending around the edge of the pixel electrode AE. The dam BA can be configured to define an opening region OA of the pixel electrode AE. The opening region OA of the pixel electrode AE ​​can correspond to the emission regions EA1, EA2, EA3, and EA4 of each sub-pixel SP1, SP2, SP3, and SP4. For example, the opening region OA of the pixel electrode AE ​​exposed by the dam BA can be configured to directly contact the emission layer EL and emit light from the emission regions EA1, EA2, EA3, and EA4.

[0089] A dam BA can be disposed within the non-emitting region NEA of each sub-pixel SP1, SP2, SP3, and SP4. The dam BA can overlap with pixel circuits CA1, CA2, CA3, and CA4, and at least one signal line. For example, the dam BA can be formed of an organic layer such as an acrylic resin, epoxy resin, phenolic resin, polyamide resin, or polyimide resin. According to embodiments of this disclosure, the dam BA can be a black dam comprising at least one of a light-absorbing material or a black material. For example, the dam BA can comprise an insulating light-absorbing material such as black resin or graphite.

[0090] An organic emitting layer EL can be disposed on the pixel electrode AE ​​and the embankment BA. The organic emitting layer EL may include a hole transport layer, an emitting material layer, and an electron transport layer. For example, when a voltage is applied to the pixel electrode AE ​​and the common electrode CE, holes and electrons can move to the organic emitting layer EL through the hole transport layer and the electron transport layer, respectively, and can combine with each other in the organic emitting layer EL to emit light. The organic emitting layer EL can be a common layer formed together above multiple sub-pixels SP1, SP2, SP3, and SP4. For example, the organic emitting layer EL can be a white emitting layer that emits white light.

[0091] A common electrode CE can be disposed on an organic emitting layer EL. The common electrode CE can be a common layer formed together above multiple sub-pixels SP1, SP2, SP3, and SP4. The common electrode CE can be disposed on pixel electrodes AE and organic emitting layer EL that are in contact with each other to constitute a light-emitting device ED. For example, the common electrode CE can be formed of a metallic material with high reflectivity, such as a stacked structure of aluminum and titanium (Ti / Al / Ti), a stacked structure of aluminum and ITO (ITO / Al / ITO), an Ag alloy, a stacked structure of Ag alloy and ITO (ITO / Ag alloy / ITO), a MoTi alloy, and a stacked structure of MoTi alloy and ITO (ITO / MoTi alloy / ITO). The Ag alloy can be an alloy of silver (Ag), palladium (Pd), copper (Cu), etc. The MoTi alloy can be an alloy of molybdenum (Mo) and titanium (Ti). The common electrode CE can be the cathode electrode of the light-emitting device ED. According to embodiments of this disclosure, the common electrode CE may also include a low-reflection metal layer. For example, the low-reflection metal layer may include a metal oxide or an alloy oxide. For example, the low-reflectivity metal layer may include copper oxide (CuOx), nickel oxide (NiOx), molybdenum oxide (MoOx), or tungsten oxide (WOx), but the embodiments disclosed herein are not limited thereto.

[0092] According to embodiments of the present disclosure, a transmittance control film may also be included on the rear surface of the substrate 111. For example, the transmittance control film may include at least one of a transparent film or an absorbent film, but embodiments of the present disclosure are not limited thereto.

[0093] Figure 6 A dam and color filter of a pixel are shown according to one embodiment of the present disclosure. Figure 7 According to one embodiment of this disclosure, along Figure 6 The cross-sectional view taken from line II-II'. Figure 6 and Figure 7 Embodiments of this disclosure are shown, wherein, with reference to Figures 1 to 5 The configuration of the embankment and color filter is modified in the described light-emitting display device. (Refer to...) Figure 6 and 7 In the following description, except for modified configurations, the same reference numerals will be used for the same parts, and redundant descriptions of them will be omitted or they will be briefly described.

[0094] refer to Figure 6 and Figure 7 According to one embodiment of the present disclosure, a light-emitting display device can be configured such that a dam portion BA of at least one of sub-pixels SP1, SP2, SP3, and SP4 extends toward the central portion of a pixel electrode AE ​​in a second direction (or Y-axis direction) intersecting a first direction (or X-axis direction) to define a non-aperture region NOA of the pixel electrode AE. In other words, for at least one of the sub-pixels SP1, SP2, SP3, and SP4, the dam portion BA may include a main portion (also referred to as a "first sub-portion") and a non-aperture dam portion NBA (also referred to as a "second sub-portion"). The main portion extends around the edge of the pixel electrode AE, and the non-aperture dam portion NBA extends from the main portion toward the central portion of the pixel electrode AE ​​in the second direction. The main portion of the dam portion BA and the non-aperture dam portion NBA together define the aperture region OA and the non-aperture region NOA of the pixel electrode AE. For example, the opening region OA of the pixel electrode AE ​​can overlap with the light-emitting regions EA1, EA2, EA3, and EA4 of each of the sub-pixels SP1, SP2, SP3, and SP4, and the non-opening region NOA of the pixel electrode AE ​​can overlap with the non-emitting region NEA of each of the sub-pixels SP1, SP2, SP3, and SP4.

[0095] The non-opening portion NBA of the dam portion BA of at least one of sub-pixels SP1, SP2, SP3, and SP4 can be disposed in the non-opening region NOA of the pixel electrode AE. For example, the non-opening portion NBA can be disposed between the pixel electrode AE ​​and the organic emitter layer EL.

[0096] For example, multiple or all of sub-pixels SP1, SP2, SP3, and SP4 may include non-aperture dam portions NBA. The non-aperture dam portions NBA may be disposed parallel to each other in a first direction (or the X-axis direction) above the corresponding pixel electrodes AE of the multiple sub-pixels SP1, SP2, SP3, and SP4. For example, the non-aperture dam portions NBA may be configured to extend from the lower edge of the pixel electrode AE ​​along a second direction to the central portion of the pixel electrode AE. The non-aperture dam portions NBA of the multiple sub-pixels SP1, SP2, SP3, and SP4 may have regions overlapping with the pixel electrodes AE of the multiple sub-pixels SP1, SP2, SP3, and SP4, and these regions may be different from each other. For example, the non-aperture dam portion NBA of the second sub-pixel SP2 may be configured to have a larger area overlapping with the pixel electrodes AE than the non-aperture dam portions NBA of the other sub-pixels SP1, SP3, and SP4, but embodiments of this disclosure are not limited thereto. For example, the non-aperture dam portions NBA may cover a portion of the pixel electrodes AE, thereby reducing the aperture ratio of the light-emitting portion. In addition, the non-opening embankment portion NBA can absorb a portion of the internal light reflected back from the common electrode CE through the pixel electrode AE, thereby reducing the cell reflectance of the light-emitting portion.

[0097] At least one color filter CF1, CF3, and CF4 can be configured not to overlap with the non-aperture region NOA of the pixel electrode AE. For example, at least one color filter CF1, CF3, and CF4 may not be located below the non-aperture dam portion NBA. For example, the non-aperture dam portion NBA may not overlap with at least one color filter CF1, CF3, and CF4. For example, the non-aperture dam portion NBA may be located between the emission regions EA1, EA2, EA3, and EA4 of the plurality of sub-pixels SP1, SP2, SP3, and SP4 and the pixel circuits CA1, CA2, CA3, and CA4 of the plurality of sub-pixels SP1, SP2, SP3, and SP4.

[0098] According to one embodiment of this disclosure, the non-aperture dam portion NBA of a plurality of sub-pixels SP1, SP2, SP3, and SP4 can be configured to extend from the dam portion BA of the non-emitting region NEA towards the central portion of the pixel electrode AE ​​of the corresponding sub-pixels SP1, SP2, SP3, and SP4, thereby defining the non-aperture region NOA of the pixel electrode AE, thereby optimizing the aperture ratio of the emitting regions EA1, EA2, EA3, and EA4, while minimizing or reducing additional masking processes. Therefore, the light-emitting display device according to an embodiment of this disclosure can reduce the increased reflectivity due to the absence of a polarizer and can improve light efficiency.

[0099] Figure 8A dam and color filter of a pixel are shown according to another embodiment of the present disclosure. Figure 9 It is according to another embodiment of this disclosure along Figure 8 The cross-sectional view taken from line III-III'. Figure 8 and Figure 9 Embodiments of this disclosure are shown, wherein, with reference to Figures 1 to 8 The configuration of the embankment and color filter has been modified in the described light-emitting display device. (Refer to...) Figure 8 and Figure 9 In the following description, except for modified configurations, the same reference numerals will be used for the same parts, and redundant descriptions of them will be omitted or they will be briefly described.

[0100] refer to Figure 8 and Figure 9 According to another embodiment of the present disclosure, the light-emitting display device can be configured such that the embankment BA of at least one of the sub-pixels SP1, SP2, SP3 and SP4 extends toward the central portion of the pixel electrode AE ​​in a second direction (or Y-axis direction) intersecting the first direction (or X-axis direction) to define the non-opening region NOA of the pixel electrode AE.

[0101] The non-opening portion NBA of the dam portion BA of at least one of sub-pixels SP1, SP2, SP3, and SP4 can be disposed in the non-opening region NOA of the pixel electrode AE. For example, the non-opening portion NBA can be disposed between the pixel electrode AE ​​and the organic emitter layer EL.

[0102] For example, multiple or all of sub-pixels SP1, SP2, SP3, and SP4 may include non-aperture dam portions NBA. The non-aperture dam portions NBA may be disposed parallel to each other in a first direction (or the X-axis direction) above the corresponding pixel electrodes AE of the multiple sub-pixels SP1, SP2, SP3, and SP4. For example, the non-aperture dam portions NBA may be configured to extend from the lower edge of the pixel electrode AE ​​toward the central portion of the pixel electrode AE ​​in a second direction. The non-aperture dam portions NBA of the multiple sub-pixels SP1, SP2, SP3, and SP4 may have regions overlapping with the pixel electrodes AE of the multiple sub-pixels SP1, SP2, SP3, and SP4, and these regions may be different from each other. For example, the non-aperture dam portion NBA of the second sub-pixel SP2 may be configured to have a larger area overlapping with the pixel electrodes AE than the non-aperture dam portions NBA of the other sub-pixels SP1, SP3, and SP4, but embodiments of this disclosure are not limited thereto. For example, the non-aperture dam portions NBA may cover a portion of the pixel electrodes AE, thereby reducing the aperture ratio of the light-emitting portion. In addition, the non-opening embankment portion NBA can absorb a portion of the internal light reflected back from the common electrode CE through the pixel electrode AE, thereby reducing the unit reflectivity of the light-emitting portion.

[0103] At least one color filter CF1, CF3, and CF4 can be configured to overlap with the non-aperture region (NOA) of the pixel electrode AE. For example, at least one color filter CF1, CF3, and CF4 can be positioned below the non-aperture dam portion NBA. For example, the non-aperture dam portion NBA can overlap with at least one color filter CF1, CF3, and CF4. The non-aperture dam portions NBA of multiple sub-pixels SP1, SP2, SP3, and SP4 can have regions overlapping with at least one color filter CF1, CF3, and CF4, and these regions can be different from each other, but the embodiments of this disclosure are not limited thereto. For example, the non-aperture dam portion NBA of the second sub-pixel SP2 can overlap with the corresponding pixel electrode AE, and the non-aperture dam portions NBA of other sub-pixels SP1, SP3, and SP4 can overlap with the corresponding pixel electrode AE ​​and at least one color filter CF1, CF3, and CF4. For example, at least one color filter CF1, CF3, and CF4 overlapping with the non-aperture dam portion NBA can absorb a portion of externally incident external light before it reaches the pixel electrode AE, thereby further reducing the unit reflectivity of the light-emitting portion.

[0104] According to another embodiment of this disclosure, the non-aperture dam portion NBA of a plurality of sub-pixels SP1, SP2, SP3, and SP4 can be configured to extend from the dam portion BA of the non-emitting region NEA toward the central portion of the pixel electrode AE ​​of the corresponding sub-pixels SP1, SP2, SP3, and SP4 to define the non-aperture region NOA of the pixel electrode AE. It can also be configured to overlap with at least one color filter CF1, CF3, and CF4 in the non-aperture region NOA, thereby optimizing the aperture ratio and reflected color of the emitting regions EA1, EA2, EA3, and EA4, while minimizing or reducing additional masking processes. Therefore, the light-emitting display device according to another embodiment of this disclosure can reduce the increased reflectivity due to the absence of a polarizer, improve light efficiency, and enhance reflected color and visibility perception.

[0105] Figure 10 A dam and color filter of a pixel are shown according to another embodiment of the present disclosure. Figure 11 It is according to another embodiment of this disclosure along Figure 10 A cross-sectional view taken from line IV-IV'. Figure 10 and Figure 11 Embodiments of this disclosure are shown, wherein, with reference to Figures 1 to 9 The configuration of the embankment and color filter has been modified in the described light-emitting display device. (Refer to...) Figure 10 and Figure 11 In the following description, except for modified configurations, the same reference numerals will be used for the same parts, and redundant descriptions of them will be omitted or they will be briefly described.

[0106] refer to Figure 10 and Figure 11 According to another embodiment of the present disclosure, the light-emitting display device can be configured such that the embankment BA of at least one of the sub-pixels SP1, SP2, SP3 and SP4 extends toward the central portion of the pixel electrode AE ​​in a second direction (or Y-axis direction) intersecting the first direction (or X-axis direction) to define the non-opening region NOA of the pixel electrode AE.

[0107] At least one non-apertured dam portion NBA of the dam BA of sub-pixels SP2 and SP4 can be disposed in the non-apertured region NOA of the pixel electrode AE. For example, the non-apertured dam portion NBA can be disposed between the pixel electrode AE ​​and the organic emitter layer EL. For example, the non-apertured dam portion NBA can be disposed in the second sub-pixel SP2 and the fourth sub-pixel SP4, while the non-apertured dam portion NBA can be not disposed in the first sub-pixel SP1 and the third sub-pixel SP3. For example, the non-apertured dam portion NBA can be configured to extend from the lower edge of the pixel electrode AE ​​of the second sub-pixel SP2 and the fourth sub-pixel SP4 towards the central portion of the pixel electrode AE ​​in a second direction. For example, the non-apertured dam portion NBA of the second sub-pixel SP2 and the fourth sub-pixel SP4 can be configured to extend further towards the central portion of the pixel electrode AE ​​in the second direction than the dam BA of the first sub-pixel SP1 and the third sub-pixel SP3.

[0108] refer to Figure 10 In the first sub-pixel SP1 and the third sub-pixel SP3, the non-aperture dam portion NBA may not be provided, while in the second sub-pixel SP2 and the fourth sub-pixel SP4, the non-aperture dam portion NBA may be provided. Therefore, the emission areas EA1 and EA3 of the first sub-pixel SP1 and the third sub-pixel SP3 can be configured to have a larger area than the emission areas EA2 and EA4 of the second sub-pixel SP2 and the fourth sub-pixel SP4.

[0109] At least one color filter CF1, CF3, and CF4 can be configured not to overlap with the non-aperture region NOA of the pixel electrode AE. For example, no color filter may be provided in the second sub-pixel SP2, and the fourth color filter CF4 may not be provided on the non-aperture embankment portion NBA of the fourth sub-pixel SP4.

[0110] According to another embodiment of this disclosure, the non-aperture dam portion NBA of the second sub-pixel SP2 and the fourth sub-pixel SP4 can be configured to extend from the dam portion BA of the non-emitting region NEA towards the central portion of the pixel electrode AE ​​of the corresponding sub-pixels SP2 and SP4 to define the non-aperture region NOA of the pixel electrode AE, and the first sub-pixel SP1 and the third sub-pixel SP3 can be configured not to include the non-aperture dam portion NBA, thereby optimizing the aperture ratio of the emitting regions EA1, EA2, EA3 and EA4, while minimizing or reducing additional masking processes. Therefore, the light-emitting display device according to another embodiment of this disclosure can reduce the increased reflectivity due to the absence of a polarizer and can improve light efficiency.

[0111] Figure 12 A dam and color filter of a pixel are shown according to another embodiment of the present disclosure. Figure 13 It is according to another embodiment of this disclosure along Figure 12 A cross-sectional view taken from line V-V'. Figure 12 and Figure 13 Embodiments of this disclosure are shown, wherein, with reference to Figures 1 to 11 The configuration of the embankment and color filter has been modified in the described light-emitting display device. For example, Figure 12 and Figure 13 It is shown in the reference Figure 10 and Figure 11 The configuration of the color filter in the described light-emitting display device is modified. (Refer to...) Figure 12 and 13 In the following description, except for modified configurations, the same reference numerals will be used for the same parts, and redundant descriptions of them will be omitted or they will be briefly described.

[0112] refer to Figure 12 and Figure 13 According to another embodiment of the present disclosure, the light-emitting display device can be configured such that the embankment BA of at least one of the sub-pixels SP1, SP2, SP3 and SP4 extends toward the central portion of the pixel electrode AE ​​in a second direction (or Y-axis direction) intersecting the first direction (or X-axis direction) to define the non-opening region NOA of the pixel electrode AE.

[0113] At least one of the first sub-pixel SP1 and the third sub-pixel SP3 adjacent to the second sub-pixel SP2 can be configured such that at least a portion of the color filters CF1 and CF3 extends in a first direction (or the X-axis direction) to overlap with the second sub-pixel SP2. For example, at least a portion of the first color filter CF1 of the first sub-pixel SP1 can be configured to extend in the first direction and overlap with the non-opening embankment portion NBA of the second sub-pixel SP2. At least a portion of the third color filter CF3 of the third sub-pixel SP3 can be configured to extend in the first direction and overlap with the non-opening embankment portion NBA of the second sub-pixel SP2.

[0114] According to another embodiment of this disclosure, at least a portion of the third color filter CF3 of the third sub-pixel SP3 may include a color filter extension CFE extending along a first direction. The color filter extension CFE of the third sub-pixel SP3 may extend in the first direction to an adjacent second sub-pixel SP2 and may be configured to overlap with the non-aperture dam portion NBA of the second sub-pixel SP2. The color filter extension CFE of the third sub-pixel SP3 may extend in the first direction to an adjacent fourth sub-pixel SP4 and may be configured to overlap with the non-aperture dam portion NBA of the fourth sub-pixel SP4. The fourth color filter CF4 may not be provided in the non-aperture dam portion NBA of the fourth sub-pixel SP4, or the fourth color filter CF4 may be provided in the non-aperture dam portion NBA of the fourth sub-pixel SP4. For example, the color filter extension CFE of the third sub-pixel SP3 may overlap with the fourth color filter CF4 in the non-aperture dam portion NBA of the fourth sub-pixel SP4. For example, the color filter extension CFE that overlaps with the non-opening embankment portion NBA can absorb a portion of the external light before it reaches the pixel electrode AE, thereby further reducing the unit reflectivity of the light-emitting portion.

[0115] refer to Figure 12 The non-aperture dam portion NBA can be omitted in the first sub-pixel SP1 and the third sub-pixel SP3, while the non-aperture dam portion NBA can be set in the second sub-pixel SP2 and the fourth sub-pixel SP4. Therefore, the emission areas EA1 and EA3 of the first sub-pixel SP1 and the third sub-pixel SP3 can be configured to have a larger area than the emission areas EA2 and EA4 of the second sub-pixel SP2 and the fourth sub-pixel SP4.

[0116] refer to Figure 13 The color filter extension CFE of the third sub-pixel SP3 can be disposed in the non-aperture dam portion NBA of the second sub-pixel SP2 and the non-aperture dam portion NBA of the fourth sub-pixel SP4. For example, the color filter extension CFE disposed in the second sub-pixel SP2 can overlap with the pixel electrode AE ​​of the second sub-pixel SP2, but can not overlap with the emitter region EA2 of the second sub-pixel SP2. For example, the color filter extension CFE disposed in the fourth sub-pixel SP4 can overlap with the pixel electrode AE ​​of the fourth sub-pixel SP4, but can not overlap with the emitter region EA4 of the fourth sub-pixel SP4. Moreover, the color filter extension CFE disposed in the fourth sub-pixel SP4 can be disposed parallel to the color filter CF4 of the fourth sub-pixel SP4 in the first direction (or the X-axis direction). For example, in the fourth sub-pixel SP4, the color filter CF4 can be disposed in the emitter region EA4, and the color filter extension CFE of the third sub-pixel SP3 can be disposed in the non-aperture region NOA.

[0117] According to another embodiment of this disclosure, the non-aperture dam portion NBA of the second sub-pixel SP2 and the fourth sub-pixel SP4 can be configured to extend from the dam portion BA of the non-emitting region NEA towards the central portion of the pixel electrode AE ​​of the corresponding sub-pixels SP2 and SP4, thereby defining the non-aperture region NOA of the pixel electrode AE. The first sub-pixel SP1 and the third sub-pixel SP3 can be configured not to include the non-aperture dam portion NBA, and the color filter CF3 of the third sub-pixel SP3 can be configured to extend to the adjacent other sub-pixels SP2 and SP4, thereby optimizing the aperture ratio and reflected color of the emitting regions EA1, EA2, EA3, and EA4, while minimizing or reducing additional masking processes. Therefore, the light-emitting display device according to another embodiment of this disclosure can reduce the increased reflectivity due to the absence of a polarizer, improve light efficiency, and enhance reflected color and visibility perception.

[0118] Figure 14 A dam and color filter of a pixel are shown according to another embodiment of the present disclosure. Figure 15 It is according to another embodiment of this disclosure along Figure 14 A cross-sectional view taken from line VI-VI'. Figure 14 and Figure 15 Embodiments of this disclosure are shown, wherein, with reference to Figures 1 to 13 The configuration of the embankment and color filter has been modified in the described light-emitting display device. For example, Figure 14 and Figure 15 Such a configuration is shown, wherein in the reference Figure 12 and Figure 13 The configuration of the color filter has been modified in the described light-emitting display device. (Refer to...) Figure 14 and Figure 15 In the following description, except for modified configurations, the same reference numerals will be used for the same parts, and redundant descriptions of them will be omitted or they will be briefly described.

[0119] refer to Figure 14 and Figure 15 According to another embodiment of the present disclosure, the light-emitting display device can be configured such that the embankment BA of at least one sub-pixel SP2 extends toward the central portion of the pixel electrode AE ​​in a second direction (or Y-axis direction) intersecting the first direction (or X-axis direction) to define the non-opening region NOA of the pixel electrode AE.

[0120] The non-aperture portion NBA of the dam BA of the second sub-pixel SP2 can be disposed in the non-aperture region NOA of the pixel electrode AE. For example, the non-aperture portion NBA can be configured to extend in a second direction from the lower edge of the pixel electrode AE ​​toward the central portion of the pixel electrode AE. For example, the non-aperture portion NBA of the second sub-pixel SP2 can be configured to extend in a second direction further than the dam BA of the first sub-pixel SP1, the third sub-pixel SP3, and the fourth sub-pixel SP4 to the central portion of the pixel electrode AE.

[0122] According to another embodiment of this disclosure, at least a portion of the third color filter CF3 of the third sub-pixel SP3 may include a color filter extension CFE extending along a first direction. The color filter extension CFE of the third sub-pixel SP3 may extend in the first direction to the adjacent second sub-pixel SP2 and may be configured to overlap with the non-opening dam portion NBA of the second sub-pixel SP2. For example, the color filter extension CFE overlapping with the non-opening dam portion NBA may absorb a portion of externally incident external light before it reaches the pixel electrode AE, thereby further reducing the unit reflectivity of the light-emitting portion.

[0123] refer to Figure 14 The non-aperture dam portion NBA can be omitted in the first sub-pixel SP1, the third sub-pixel SP3, and the fourth sub-pixel SP4, but can be set in the second sub-pixel SP2. Therefore, the emission area EA2 of the second sub-pixel SP2 can be configured to have a smaller area than the emission areas EA1, EA3, and EA4 of the other sub-pixels SP1, SP3, and SP4.

[0124] refer to Figure 15 The color filter extension CFE of the third sub-pixel SP3 can be located in the non-opening embankment portion NBA of the second sub-pixel SP2. For example, the color filter extension CFE of the third sub-pixel SP3 located in the second sub-pixel SP2 can overlap with the pixel electrode AE ​​of the second sub-pixel SP2, but can not overlap with the emission region EA2 of the second sub-pixel SP2.

[0125] According to another embodiment of this disclosure, the non-aperture dam portion NBA of the second sub-pixel SP2 can be configured to extend from the dam portion BA of the non-emitting region NEA of the corresponding sub-pixel SP2 toward the central portion of the pixel electrode AE, thereby defining the non-aperture region NOA of the pixel electrode AE. The first sub-pixel SP1, the third sub-pixel SP3, and the fourth sub-pixel SP4 may not include the non-aperture dam portion NBA, and the color filter CF3 of the third sub-pixel SP3 can be configured to extend to the second sub-pixel SP2, thereby optimizing the aperture ratio and reflected color of the emitting regions EA1, EA2, EA3, and EA4, while minimizing or reducing additional masking processes. Therefore, the light-emitting display device according to another embodiment of this disclosure can reduce the increased reflectivity due to the absence of a polarizer, improve light efficiency, and enhance reflected color and visibility perception.

Figure 17 It is according to another embodiment of this disclosure along Figure 16 A cross-sectional view taken from line VII-VII'. Figure 16 and Figure 17 Embodiments of this disclosure are shown, wherein, with reference to Figures 1 to 15 The configuration of the embankment and color filter has been modified in the described light-emitting display device. (Refer to...) Figure 16 and Figure 17 In the following description, except for modified configurations, the same reference numerals will be used for the same parts, and redundant descriptions of them will be omitted or they will be briefly described.

[0127] refer to Figure 16 and Figure 17 According to another embodiment of the present disclosure, the light-emitting display device can be configured such that the embankment BA of at least one sub-pixel SP2 extends toward the central portion of the pixel electrode AE ​​in a second direction (or Y-axis direction) intersecting the first direction (or X-axis direction) to define the non-opening region NOA of the pixel electrode AE.

[0128] At least a portion of the color filters CF1 and CF3 of the first sub-pixel SP1 and the third sub-pixel SP3 adjacent to the second sub-pixel SP2 can be configured to extend in a first direction (or the X-axis direction) and overlap with the second sub-pixel SP2.

[0129] According to another embodiment of this disclosure, at least a portion of the first color filter CF1 of the first sub-pixel SP1 may include a color filter extension portion CFE extending along a first direction, and at least a portion of the third color filter CF3 of the third sub-pixel SP3 may include a color filter extension portion CFE extending along the first direction. For example, the color filter extension portions CFE of the first sub-pixel SP1 and the third sub-pixel SP3 may overlap with the pixel electrode AE ​​of the second sub-pixel SP2. For example, the color filter extension portion CFE of the first sub-pixel SP1 may be configured to overlap with the opening region OA of the pixel electrode AE ​​of the second sub-pixel SP2, and the color filter extension portion CFE of the third sub-pixel SP3 may be configured to overlap with the non-opening region NOA of the pixel electrode AE ​​of the second sub-pixel SP2. For example, the color filter extension portion CFE of the third sub-pixel SP3 may overlap with the non-opening embankment portion NBA of the second sub-pixel SP2. Alternatively, the color filter extension CFE of the first sub-pixel SP1 can be configured to overlap with the non-aperture region NOA of the pixel electrode AE ​​of the second sub-pixel SP2, and the color filter extension CFE of the third sub-pixel SP3 can be configured to overlap with the aperture region OA of the pixel electrode AE ​​of the second sub-pixel SP2. For example, the color filter extension CFE of the first sub-pixel SP1 can overlap with the non-aperture dam portion NBA of the second sub-pixel SP2. For example, the color filter extension CFE of the first sub-pixel SP1 located in the second emission region EA2 and the color filter extension CFE of the third sub-pixel SP3 overlapping with the non-aperture dam portion NBA can absorb a portion of the external light before it reaches the pixel electrode AE, thereby further reducing the unit reflectivity of the light-emitting portion.

[0130] refer to Figure 16 Instead of setting the non-aperture embankment portion NBA in the first sub-pixel SP1, the third sub-pixel SP3, and the fourth sub-pixel SP4, the non-aperture embankment portion NBA can be set in the second sub-pixel SP2. Therefore, the emission area EA2 of the second sub-pixel SP2 can be configured to have a smaller area than the emission areas EA1, EA3, and EA4 of the other sub-pixels SP1, SP3, and SP4.

[0131] Combination Figure 15 refer to Figure 17The color filter extension CFE of the third sub-pixel SP3 can be disposed within the non-aperture embankment portion NBA of the second sub-pixel SP2. For example, the color filter extension CFE of the third sub-pixel SP3 disposed within the second sub-pixel SP2 can overlap with the pixel electrode AE ​​of the second sub-pixel SP2, but may not overlap with the emission region EA2 of the second sub-pixel SP2. The color filter extension CFE of the first sub-pixel SP1 can be disposed within the emission region EA2 of the second sub-pixel SP2. For example, the color filter extension CFE of the first sub-pixel SP1 disposed within the second sub-pixel SP2 can overlap with the pixel electrode AE ​​of the second sub-pixel SP2, and may overlap with the emission region EA2 of the second sub-pixel SP2.

[0132] According to another embodiment of this disclosure, the non-aperture dam portion NBA of the second sub-pixel SP2 can be configured to extend from the dam portion BA of the non-emitting region NEA of the corresponding sub-pixel SP2 toward the central portion of the pixel electrode AE, thereby defining the non-aperture region NOA of the pixel electrode AE. The first sub-pixel SP1, the third sub-pixel SP3, and the fourth sub-pixel SP4 can be configured not to include the non-aperture dam portion NBA, and the color filters CF1 and CF3 of the first sub-pixel SP1 and the third sub-pixel SP3 can be configured to extend to the second sub-pixel SP2, thereby optimizing the aperture ratio and reflected color of the emitting regions EA1, EA2, EA3, and EA4, while minimizing or reducing additional masking processes. Therefore, the light-emitting display device according to another embodiment of this disclosure can reduce the increased reflectivity due to the absence of a polarizer, improve light efficiency, and enhance reflected color and visibility perception.

[0133] Figure 18 A dam and color filter of a pixel are shown according to another embodiment of the present disclosure. Figure 19 A dam and color filter of a pixel are shown according to another embodiment of the present disclosure. Figure 18 and Figure 19 Embodiments of this disclosure are shown, wherein, with reference to Figures 1 to 17 The configuration of the embankment and color filter has been modified in the described light-emitting display device. (Refer to...) Figure 18 and 19 In the following description, except for modified configurations, the same reference numerals will be used for the same parts, and redundant descriptions of them will be omitted or they will be briefly described.

[0134] refer to Figure 18According to another embodiment of the present disclosure, the light-emitting display device can be configured such that the bank portion BA of at least one sub-pixel SP2 and SP4 may include a first sub-non-opening bank portion NBAa and a second sub-non-opening bank portion NBAb spaced apart from each other along a second direction (or Y-axis direction), such that the opening region OA of the pixel electrode AE ​​is located between the first sub-non-opening bank portion NBAa and the second sub-non-opening bank portion NBAb.

[0135] The first non-aperture dam portion NBAa can extend from the lower edge of the pixel electrode AE ​​toward the center of the pixel electrode AE ​​in the second direction, and the second non-aperture dam portion NBAb can extend from the upper edge of the pixel electrode AE ​​toward the center of the pixel electrode AE ​​in the second direction. Alternatively, instead of setting the first non-aperture dam portion NBAa and the second non-aperture dam portion NBAb in the first sub-pixel SP1 and the third sub-pixel SP3, the first non-aperture dam portion NBAa and the second non-aperture dam portion NBAb can be set in the second sub-pixel SP2 and the fourth sub-pixel SP4.

[0136] Instead of setting the first non-aperture dam portion NBAa and the second non-aperture dam portion NBAb in the first sub-pixel SP1 and the third sub-pixel SP3, the first non-aperture dam portion NBAa and the second non-aperture dam portion NBAb can be set in the second sub-pixel SP2 and the fourth sub-pixel SP4. Therefore, the emission regions EA2 and EA4 of the second sub-pixel SP2 and the fourth sub-pixel SP4 can be configured to have larger areas than the emission regions EA1 and EA3 of the first sub-pixel SP1 and the third sub-pixel SP3. For example, the first non-aperture dam portion NBAa and the second non-aperture dam portion NBAb of the second sub-pixel SP2 can overlap with the pixel electrode AE ​​of the second sub-pixel SP2. For example, the first non-aperture dam portion NBAa and the second non-aperture dam portion NBAb of the fourth sub-pixel SP4 can overlap with the pixel electrode AE ​​of the fourth sub-pixel SP4, and can also overlap with the color filter CF4 of the fourth sub-pixel SP4.

[0137] According to another embodiment of this disclosure, a first non-aperture dam portion NBAa and a second non-aperture dam portion NBAb can be provided in the second sub-pixel SP2 and the fourth sub-pixel SP4, and the first non-aperture dam portion NBAa and the second non-aperture dam portion NBAb can be omitted in the first sub-pixel SP1 and the third sub-pixel SP3. Furthermore, the color filter CF4 of the fourth sub-pixel SP4 can be configured to overlap with the first non-aperture dam portion NBAa and the second non-aperture dam portion NBAb, thereby optimizing the aperture ratio and reflected color of the emitting regions EA1, EA2, EA3, and EA4, while minimizing or reducing additional masking processes. Therefore, the light-emitting display device according to another embodiment of this disclosure can reduce the increased reflectivity due to the absence of a polarizer, improve light efficiency, and enhance reflected color and perceived visibility.

[0138] refer to Figure 19 According to another embodiment of the present disclosure, the light-emitting display device may include a first non-opening embankment portion NBA1 and a second non-opening embankment portion NBA2.

[0139] The first non-aperture dam portion NBA1 can be disposed in the non-aperture region NOA of the pixel electrode AE ​​of the second sub-pixel SP2, and the second non-aperture dam portion NBA2 can be disposed in the non-aperture region NOA of the pixel electrode AE ​​of the fourth sub-pixel SP4. For example, the first non-aperture dam portion NBA1 and the second non-aperture dam portion NBA2 can be configured with different shapes. For example, the first non-aperture dam portion NBA1 can be configured to extend further in a second direction than the second non-aperture dam portion NBA2.

[0140] The first non-aperture dam portion NBA1 and the second non-aperture dam portion NBA2 may not be provided in the first sub-pixel SP1 and the third sub-pixel SP3. The first non-aperture dam portion NBA1 may be provided in the second sub-pixel SP2, and the second non-aperture dam portion NBA2 may be provided in the fourth sub-pixel SP4. Furthermore, the area where the first non-aperture dam portion NBA1 overlaps with the pixel electrode AE ​​of the second sub-pixel SP2 may be configured to have a larger area than the area where the second non-aperture dam portion NBA2 overlaps with the pixel electrode AE ​​of the fourth sub-pixel SP4. Therefore, the emission regions EA1 and EA3 of the first sub-pixel SP1 and the third sub-pixel SP3 may be configured to have a larger area than the emission regions EA2 and EA4 of the second sub-pixel SP2 and the fourth sub-pixel SP4, and the emission region EA2 of the second sub-pixel SP2 may be configured to have a smaller area than the emission region EA4 of the fourth sub-pixel SP4. For example, the first non-aperture dam portion NBA1 of the second sub-pixel SP2 may overlap with the pixel electrode AE ​​of the second sub-pixel SP2. For example, the second non-aperture embankment portion NBA2 of the fourth sub-pixel SP4 can overlap with the pixel electrode AE ​​of the fourth sub-pixel SP4, and can also overlap with the color filter CF4 of the fourth sub-pixel SP4.

[0141] According to another embodiment of this disclosure, a first non-aperture dam portion NBA1 and a second non-aperture dam portion NBA2 can be provided in the second sub-pixel SP2 and the fourth sub-pixel SP4, or the first non-aperture dam portion NBA1 and the second non-aperture dam portion NBA2 can be omitted in the first sub-pixel SP1 and the third sub-pixel SP3. Furthermore, the color filter CF4 of the fourth sub-pixel SP4 can be configured to overlap with the second non-aperture dam portion NBA2, thereby optimizing the aperture ratio and reflected color of the emitting regions EA1, EA2, EA3, and EA4, while minimizing or reducing additional masking processes. Therefore, the light-emitting display device according to another embodiment of this disclosure can reduce the increased reflectivity due to the absence of a polarizer, improve light efficiency, and enhance reflected color and visibility perception.

[0142] Figure 20 A dam and color filter of a pixel are shown according to another embodiment of the present disclosure. Figure 21 It is according to another embodiment of this disclosure along Figure 20 A cross-sectional view taken from line VIII-VIII'. Figure 20 and Figure 21 Embodiments of this disclosure are shown, wherein, with reference to Figures 1 to 19 The configuration of the embankment and color filter has been modified in the described light-emitting display device. (Refer to...) Figure 20 and Figure 21In the following description, except for modified configurations, the same reference numerals will be used for the same parts, and redundant descriptions of them will be omitted or they will be briefly described.

[0143] refer to Figure 20 and Figure 21 According to another embodiment of the present disclosure, the light-emitting display device can be configured such that a dam BA disposed between a plurality of sub-pixels SP1, SP2, SP3, and SP4 extends along a first direction (or the X-axis direction) toward the central portion of the pixel electrode AE ​​to define a non-aperture region NOA of the pixel electrode AE. For example, the dam BA adjacent to the second sub-pixel SP2 and the fourth sub-pixel SP4 may include a non-aperture dam portion NBA disposed in the non-aperture region NOA of the pixel electrode AE ​​of the second sub-pixel SP2 and the fourth sub-pixel SP4 in the first direction. For example, the non-aperture dam portion NBA may be configured to extend in the first direction from the two lateral end edges of the pixel electrode AE ​​of the second sub-pixel SP2 and the fourth sub-pixel SP4 toward the central portion of the pixel electrode AE.

[0144] The non-aperture dam portion NBA of the second sub-pixel SP2 can extend from the dam portion BA located between the first sub-pixel SP1 and the second sub-pixel SP2 toward the central portion of the pixel electrode AE ​​of the second sub-pixel SP2. Optionally or additionally, the non-aperture dam portion NBA of the second sub-pixel SP2 can extend from the dam portion BA located between the second sub-pixel SP2 and the third sub-pixel SP3 toward the central portion of the pixel electrode AE ​​of the second sub-pixel SP2 to define a non-aperture region NOA of the pixel electrode AE. For example, the non-aperture dam portion NBA of the fourth sub-pixel SP4 can extend from the main body portion of the dam portion BA located between the third sub-pixel SP3 and the fourth sub-pixel SP4 toward the central portion of the pixel electrode AE ​​of the fourth sub-pixel SP4. Optionally or additionally, the non-aperture dam portion NBA of the fourth sub-pixel SP4 can extend from the main body portion of the dam portion BA located between the fourth sub-pixel SP4 and another adjacent pixel SP toward the central portion of the pixel electrode AE ​​of the fourth sub-pixel SP4 to define a non-aperture region NOA of the pixel electrode AE. Therefore, the emission regions EA2 and EA4 of the second sub-pixel SP2 and the fourth sub-pixel SP4 can be configured to have smaller areas than the emission regions EA1 and EA3 of the first sub-pixel SP1 and the third sub-pixel SP3. For example, the non-aperture dam portion NBA of the second sub-pixel SP2 can overlap with the pixel electrode AE ​​of the second sub-pixel SP2. Similarly, the non-aperture dam portion NBA of the fourth sub-pixel SP4 can overlap with the pixel electrode AE ​​of the fourth sub-pixel SP4, and can also overlap with the color filter CF4 of the fourth sub-pixel SP4.

[0145] According to another embodiment of this disclosure, the non-aperture dam portion NBA of the second sub-pixel SP2 and the fourth sub-pixel SP4 can extend from the dam portion BA located between the sub-pixels toward the central portion of the pixel electrode AE ​​of the corresponding sub-pixels SP2 and SP4 to define the non-aperture region NOA of the pixel electrode AE, and the first sub-pixel SP1 and the third sub-pixel SP3 can be configured not to include the non-aperture dam portion NBA, thereby optimizing the aperture ratio and reflected color of the emitting regions EA1, EA2, EA3 and EA4, while minimizing or reducing additional masking processes. Therefore, the light-emitting display device according to another embodiment of this disclosure can reduce the increased reflectivity due to the absence of a polarizer, improve light efficiency, and enhance reflected color and perceived visibility.

[0146] Figure 22 A dam and color filter of a pixel are shown according to another embodiment of the present disclosure. Figure 23 It is according to another embodiment of this disclosure along Figure 22 The cross-sectional view taken by line IX-IX'. Figure 22 and Figure 23 Embodiments of this disclosure are shown, wherein, with reference to Figures 1 to 21 The configuration of the embankment and color filter has been modified in the described light-emitting display device. (Refer to...) Figure 22 and Figure 23 In the following description, except for modified configurations, the same reference numerals will be used for the same parts, and redundant descriptions of them will be omitted or they will be briefly described.

[0147] refer to Figure 22 and Figure 23 According to another embodiment of the present disclosure, the light-emitting display device can be configured such that the embankment BA disposed between a plurality of sub-pixels SP1, SP2, SP3 and SP4 can extend along a first direction (or the X-axis direction) toward the central portion of the pixel electrode AE ​​to define a non-opening region NOA of the pixel electrode AE.

[0148] At least a portion of the color filters CF1 and CF3 of the first sub-pixel SP1 and the third sub-pixel SP3 adjacent to the second sub-pixel SP2 may extend in a first direction (or the X-axis direction) and may be configured to overlap with the second sub-pixel SP2. For example, at least a portion of the third color filter CF3 of the third sub-pixel SP3 may include a color filter extension portion CFE extending in the first direction. The color filter extension portion CFE of the third sub-pixel SP3 may be configured to overlap with the non-opening embankment portion NBA of the second sub-pixel SP2.

[0149] The non-aperture dam portion NBA of the second sub-pixel SP2 can extend from the dam BA located between the first sub-pixel SP1 and the second sub-pixel SP2 toward the central portion of the pixel electrode AE ​​of the second sub-pixel SP2, and can also extend from the dam BA located between the second sub-pixel SP2 and the third sub-pixel SP3 toward the central portion of the pixel electrode AE ​​of the second sub-pixel SP2, thereby defining the non-emitting area NOA of the pixel electrode AE. Similarly, the non-aperture dam portion NBA of the fourth sub-pixel SP4 can extend from the dam BA located between the third sub-pixel SP3 and the fourth sub-pixel SP4 toward the central portion of the pixel electrode AE ​​of the fourth sub-pixel SP4, and can also extend from the dam BA located between the fourth sub-pixel SP4 and another adjacent pixel SP toward the central portion of the pixel electrode AE ​​of the fourth sub-pixel SP4, thereby defining the non-emitting area NOA of the pixel electrode AE. Therefore, the emission areas EA2 and EA4 of the second sub-pixel SP2 and the fourth sub-pixel SP4 can have smaller areas than the emission areas EA1 and EA3 of the first sub-pixel SP1 and the third sub-pixel SP3.

[0150] The color filter extension CFE of the third sub-pixel SP3 can be located within the non-aperture dam portion NBA of the second sub-pixel SP2. For example, the color filter extension CFE of the third sub-pixel SP3 can overlap with the non-aperture dam portion NAB located on the right side of the second sub-pixel SP2. The color filter extension CFE of the third sub-pixel SP3 can overlap with the pixel electrode AE ​​of the second sub-pixel SP2, but can not overlap with the emitter region EA2 of the second sub-pixel SP2.

[0151] According to another embodiment of this disclosure, the non-aperture dam portion NBA of the second sub-pixel SP2 and the fourth sub-pixel SP4 can extend from the dam portion BA located between the sub-pixels to the central portion of the pixel electrode AE ​​of the corresponding sub-pixels SP2 and SP4 to define the non-aperture region NOA of the pixel electrode AE. The first sub-pixel SP1 and the third sub-pixel SP3 may not include the non-aperture dam portion NBA, and the color filter CF3 of the third sub-pixel SP3 can be configured to overlap with the non-aperture dam portion NBA of the second sub-pixel SP2, thereby optimizing the aperture ratio and reflected color of the emitting regions EA1, EA2, EA3 and EA4, while minimizing or reducing additional masking processes. Therefore, the light-emitting display device according to another embodiment of this disclosure can reduce the increased reflectivity due to the absence of a polarizer, improve light efficiency, and enhance the perceived reflected color and visibility.
