[0017] The lower barrier pattern may contain materials different from those of the upper barrier pattern.

[0018] Each upper opening can be smaller than the size of each optical lens. Each lower opening can be larger than the size of each upper opening.

[0019] Each of the two light-emitting regions in each sub-pixel may include a region overlapping with one of the optical lenses and a region located outside the optical lens.

Detailed Implementation

[0022] In the following detailed description, with reference to the accompanying drawings illustrating some embodiments of the present disclosure, details relating to the above-described objectives, technical configurations, and operational effects of the embodiments of the present disclosure will become clear. Embodiments of the present disclosure are provided here so that the technical spirit of the present disclosure can be satisfactorily conveyed to those skilled in the art; therefore, the present disclosure may be embodied in other forms and is not limited to the embodiments described below.

[0023] Furthermore, throughout the specification and drawings, identical or very similar elements may be represented by the same reference numerals, and for convenience, the length and thickness of layers and regions may be exaggerated. It should be understood that when a first element is referred to as being "on" a second element, although the first element may be disposed on the second element to contact the second element, a third element may be inserted between the first and second elements.

[0024] Here, terms such as "first" and "second" can be used to distinguish one element from another. However, without departing from the spirit of this disclosure, the first and second elements can be arbitrarily named for the convenience of those skilled in the art.

[0025] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the scope of this disclosure. For example, unless the context clearly indicates otherwise, elements described in the singular are intended to include multiple elements. Furthermore, it will be further understood in this disclosure that the terms “comprising” and “including” specify the presence of the described features, integers, steps, operations, elements, components, and / or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or combinations thereof.

[0026] Furthermore, unless “directly” is used, the terms “connect” and “join” can include two components “connected” or “joined” by one or more other components located between the two components.

[0027] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which the example embodiments pertain. It will be further understood that terms defined, for example, in common dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant field and should not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0028] (Example) Figure 1 This is a view schematically showing the location where a display device according to an embodiment of the present disclosure is installed. Figure 2This is a schematic view of a display device according to an embodiment of the present disclosure. Figure 3 yes Figure 2 A magnified view of region K in the image. Figure 4 It is along Figure 3 The view captured by I-I'. Figure 5 This is a view showing the driving circuitry of a sub-pixel in the display panel of a display device according to an embodiment of the present disclosure.

[0029] Reference Figures 1 to 5 The display device according to embodiments of the present disclosure may include a display panel DP installed in an automobile. The display panel DP can provide images to a driver sitting in a driver's seat DS and / or a passenger sitting in a passenger seat PS. For example, the display panel DP may be disposed between the driver's seat DS and the passenger seat PS. The driver sitting in the driver's seat DS and the passenger sitting in the passenger seat PS may be positioned in a direction inclined towards the front of the display panel DP.

[0030] The display panel DP can provide a different image to the passenger sitting in the passenger seat PS than to the driver sitting in the driver seat DS. For example, the display panel DP can provide the driver sitting in the driver seat DS with a first image containing necessary information for vehicle operation, and provide the passenger sitting in the passenger seat PS with a second image containing information unrelated to vehicle operation.

[0031] The second image can be provided simultaneously with the first image. For example, a first light L1 for generating the first image and a second light L2 for generating the second image can be emitted simultaneously from the display panel DP. The first light L1 cannot be recognized by a passenger sitting in the passenger seat PS. The second light L2 cannot be recognized by the driver sitting in the driver's seat DS. Therefore, in the display device according to the embodiments of the present disclosure, the visibility of the first image and the visibility of the second image can be improved. Furthermore, in the display device according to the embodiments of the present disclosure, driver distraction caused by the second image can be prevented. Therefore, in the display device according to the embodiments of the present disclosure, accidents caused by driver distraction while driving a car can be reduced.

[0032] Multiple pixel regions (PAs) can be set within the display panel (DP). Each pixel region (PA) can display various colors. For example, each pixel region (PA) may include subpixels (SPs). Each subpixel can display a specific color. The subpixels of each pixel region (PA) can display different colors. For example, each pixel region (PA) may include a red subpixel (R-SP) to represent red, a green subpixel (G-SP) to represent green, and a blue subpixel (B-SP) to represent blue.

[0033] Two light-emitting regions can be defined in each sub-pixel SP. For example, each sub-pixel SP may include a first light-emitting region EA1 and a second light-emitting region EA2. The first light-emitting region EA1 of each sub-pixel SP can emit a first light L1 to generate a first image provided to the driver sitting in the driver's seat DS. The second light-emitting region EA2 of each sub-pixel SP can emit a second light L2 to generate a second image provided to the passenger sitting in the passenger seat PS.

[0034] The second light-emitting area EA2 of each sub-pixel SP can be arranged side-by-side with the first light-emitting area EA1 of the corresponding sub-pixel SP in the first direction X. Here, the first direction X can be defined as the direction between the driver's seat DS and the passenger seat PS. The windshield of the car can be arranged side-by-side with the display panel in a second direction perpendicular to the first direction. For example, the third direction Z, perpendicular to the first direction X and the second direction Y, can be the front direction of the display panel DP.

[0035] Each sub-pixel SP may include a first light-emitting device 301 overlapping a first light-emitting region EA1 and a second light-emitting device 302 overlapping a second light-emitting region EA2. Each of the first light-emitting device 301 and the second light-emitting device 302 in each sub-pixel SP can generate light and emit light. For example, a first light L1 may be generated by the first light-emitting device 301 of each sub-pixel SP, and a second light L2 may be generated by the second light-emitting device 302 of each sub-pixel SP. The second light-emitting device 302 in each sub-pixel SP may have the same stacking structure as the first light-emitting device 301 of the corresponding sub-pixel SP. For example, each of the first light-emitting device 301 and the second light-emitting device 302 in each sub-pixel SP may include a light-emitting unit 320 disposed between a first electrode 310 and a second electrode 330.

[0036] The light-emitting unit 320 can generate light with a brightness corresponding to the voltage difference between the first electrode 310 and the second electrode 330. For example, the light-emitting unit 320 may include at least one light-emitting material layer (EML). The light-emitting material layer may include organic light-emitting materials, inorganic light-emitting materials, and mixed light-emitting materials. The light-emitting unit 320 may have a multilayer structure. For example, the light-emitting unit 320 may also include at least one of a hole injection layer (HIL), a hole transport layer (HTL), an electron transport layer (ETL), and an electron injection layer (EIL).

[0037] The first electrode 310 and the second electrode 330 may contain conductive materials. The second electrode 330 may contain a different material than the first electrode 310. For example, the second electrode 330 may have a higher transmittance than the first electrode 310. The reflectivity of the first electrode 310 may be higher than that of the second electrode 330. For example, the first electrode 310 may be a reflective electrode containing metals (e.g., aluminum (Al) and silver (Ag)), and the second electrode 330 may be a transparent electrode made of a transparent conductive material (e.g., ITO and IZO). Therefore, in the display device according to an embodiment of the present disclosure, light generated by the light-emitting unit 320 can be emitted through the second electrode 330.

[0038] The second light L2 emitted from the second light-emitting device 302 of each sub-pixel SP can display the same color as the first light L1 emitted from the first light-emitting device 301 of the corresponding sub-pixel SP. For example, the light-emitting unit 320 of the second light-emitting device 302 in each sub-pixel can include the same light-emitting material layer as the light-emitting unit 320 of the second light-emitting device 302 in the corresponding sub-pixel SP. The light-emitting unit 320 of the second light-emitting device 302 in each sub-pixel SP can be formed simultaneously with the light-emitting unit 320 of the first light-emitting device 301 in the corresponding sub-pixel SP.

[0039] The second light-emitting device 302 of each sub-pixel SP can be controlled independently of the first light-emitting device 301 of the corresponding sub-pixel SP. For example, a first driving circuit DC1 electrically connected to the first light-emitting device 301 and a second driving circuit DC2 electrically connected to the second light-emitting device 302 can be disposed within each sub-pixel SP. The second driving circuit DC2 of each sub-pixel SP can be isolated from the first driving circuit DC1 of the corresponding sub-pixel SP. For example, each of the first driving circuit DC1 and the second driving circuit DC2 in each sub-pixel SP can be electrically connected to signal wirings GL, DL, and PL.

[0040] The signal wiring GL, DL, and PL may include a gate line GL, a data line DL, and a power supply line PL. The gate line GL may be electrically connected to a gate driver GD. For example, the gate driver GD can apply a gate signal through the gate line GL. The data line DL may be electrically connected to a data driver DD. For example, the data driver DD can apply a data signal through the data line DL. The power supply voltage may be applied through the power supply line PL to a first driving circuit DC1 and a second driving circuit DC2 for each sub-pixel SP. For example, the first driving circuit DC1 and the second driving circuit DC2 for each sub-pixel SP can generate a driving current corresponding to the data signal based on the gate signal using the power supply voltage. The second driving circuit DC2 for each sub-pixel SP may have the same structure as the first driving circuit DC1 of the corresponding sub-pixel SP. For example, each of the first driving circuit DC1 and the second driving circuit DC2 in each sub-pixel SP may include a first thin-film transistor TR1, a second thin-film transistor TR2, and a storage capacitor Cst.

[0041] A first thin-film transistor TR1 can transmit a data signal to a second thin-film transistor TR2 based on a gate signal. For example, the first thin-film transistor TR1 can be used as a switching thin-film transistor. The first thin-film transistor TR1 may include a first semiconductor pattern, a first gate, a first drain, and a first source. For example, the first gate may be electrically connected to a gate line GL, and the first drain may be electrically connected to a data line DL. The first semiconductor pattern may include a first drain region, a first source region, and a first channel region, wherein the first drain region is electrically connected to a first drain, the first source region is electrically connected to a first source, and the first channel region is disposed between the first drain region and the first source region. The first source can be electrically connected to the first drain through the first channel region of the first semiconductor pattern based on a signal applied to the first gate.

[0042] The second thin-film transistor TR2 can generate a drive current based on a data signal using a power supply voltage. For example, the second thin-film transistor TR2 can be used as a driving thin-film transistor. The second thin-film transistor TR2 may include a second semiconductor pattern 221, a second gate 223, a second drain 225, and a second source 227. For example, the second gate 223 may be electrically connected to a first source, and the second drain 225 may be electrically connected to a power supply voltage supply line PL. The second semiconductor pattern 221 may include a second drain region, a second source region, and a second channel region, the second drain region being electrically connected to the second drain 225, the second source region being electrically connected to the second source 227, and the second channel region being disposed between the second drain region and the second source region. The second channel region of the second semiconductor pattern 221 may have a conductivity corresponding to the voltage of the signal applied to the second gate 223.

[0043] The operation of the second thin-film transistor TR2 can be maintained within a frame by the storage capacitor Cst. For example, the storage capacitor Cst can maintain the voltage of the signal applied to the second gate 223 for one frame. The storage capacitor Cst can have a stacked structure of capacitor electrodes. For example, the storage capacitor Cst can have a structure in which a first capacitor electrode electrically connected to the second gate 223 and a second capacitor electrode electrically connected to the second source 227 are stacked.

[0044] The display panel DP may include a device substrate 100, which supports a first driving circuit DC1 and a second driving circuit DC2 for each sub-pixel SP. For example, the first driving circuit DC1 and the second driving circuit DC2 for each sub-pixel SP may be disposed on the upper surface of the device substrate 100. The device substrate 100 may contain an insulating material. For example, the device substrate 100 may contain glass or plastic. At least one insulating layer 110, 120, 130, 140, and 150 for preventing accidental electrical connections may be disposed on the upper surface of the device substrate 100. For example, a buffer insulating layer 110, a gate insulating layer 120, an interlayer insulating layer 130, a device planarization layer 140, and a dam insulating layer 150 may be disposed on the upper surface of the device substrate 100.

[0045] The buffer insulating layer 110 may be disposed close to the device substrate 100. For example, the buffer insulating layer 110 may be in direct contact with the upper surface of the device substrate 100. The gate insulating layer 120 may be disposed on the buffer insulating layer 110. For example, the second semiconductor pattern 221 of each sub-pixel SP may be disposed between the buffer insulating layer 110 and the gate insulating layer 120. The interlayer insulating layer 130 may be disposed on the gate insulating layer 120. For example, the second gate 223 of each sub-pixel SP may be disposed between the gate insulating layer 120 and the interlayer insulating layer 130. The device planarization layer 140 may be disposed on the interlayer insulating layer 130. For example, the second drain 225 and the second source 227 of each sub-pixel SP may be disposed between the interlayer insulating layer 130 and the device planarization layer 140.

[0046] The buffer insulating layer 110, gate insulating layer 120, interlayer insulating layer 130, and device planarization layer 140 may comprise insulating materials. The device planarization layer 140 may have higher fluidity than the buffer insulating layer 110, gate insulating layer 120, and interlayer insulating layer 130. For example, the buffer insulating layer 110, gate insulating layer 120, and interlayer insulating layer 130 may be inorganic insulating layers made of inorganic insulating materials, and the device planarization layer 140 may be an organic insulating layer made of organic insulating materials. The thickness difference caused by the first driving circuit DC1 and the second driving circuit DC2 for each sub-pixel SP can be eliminated by the device planarization layer 140. For example, the upper surface of the device planarization layer 140 opposite to the device substrate 100 may be flat.

[0047] A dam insulating layer 150 may be disposed on the device planarization layer 140. The dam insulating layer 150 may define a first light-emitting region EA1 and a second light-emitting region EA2 in each sub-pixel SP. For example, portions of the upper surface of the device planarization layer 140 that overlap with the first light-emitting region EA1 of each sub-pixel SP and portions of the upper surface of the device planarization layer 140 that overlap with the second light-emitting region EA2 of each sub-pixel SP may be exposed by the dam insulating layer 150. A first light-emitting device 301 of each sub-pixel SP may be disposed on the portion of the upper surface of the device planarization layer 140 exposed by the dam insulating layer 150 that overlaps with the first light-emitting region EA1 of each sub-pixel SP, and a second light-emitting device 302 of each sub-pixel SP may be disposed on the portion of the upper surface of the device planarization layer 140 exposed by the dam insulating layer 150 that overlaps with the second light-emitting region EA2 of each sub-pixel SP. For example, the first electrode 310, light-emitting unit 320, and second electrode 330 of each of the first light-emitting device 301 and the second light-emitting device 302 in each sub-pixel SP can be sequentially stacked on the upper surface of the device planarization layer 140. The portion of the device substrate 100 that overlaps with the insulating layer 150 can be defined as a non-light-emitting region in which no light is generated.

[0048] The dam insulating layer 150 may comprise an insulating material. For example, the dam insulating layer 150 may be an organic insulating layer made of an organic insulating material. The first electrode 310 of the first light-emitting device 301 in each sub-pixel SP may be electrically connected to the first driving circuit DC1 of the corresponding sub-pixel SP. For example, the first electrode 310 of the first light-emitting device 301 in each sub-pixel SP may be in direct contact with the second source 227 of the first driving circuit DC1 in the corresponding sub-pixel SP. The first electrode 310 of the second light-emitting device 302 in each sub-pixel SP may be electrically connected to the second driving circuit DC2 of the corresponding sub-pixel SP. For example, the first electrode 310 of the second light-emitting device 302 in each sub-pixel SP may be in direct contact with the second source 227 of the second driving circuit DC2 in the corresponding sub-pixel SP. The first electrode 310 of the second light-emitting device 302 in each sub-pixel SP may be insulated from the first electrode 310 of the first light-emitting device 301 in the corresponding sub-pixel SP through the dam insulating layer 150. For example, the dam insulating layer 150 may cover the edge of each first electrode 310 in each sub-pixel SP.

[0049] The second light-emitting region EA2 of each sub-pixel SP may have the same length as the first light-emitting region EA1 of the corresponding sub-pixel SP in the first direction X. The second light-emitting region EA2 of each sub-pixel SP may also have the same length as the first light-emitting region EA1 of the corresponding sub-pixel SP in the second direction Y. For example, the second light-emitting region EA2 of each sub-pixel SP may have the same size as the first light-emitting region EA1 of the corresponding sub-pixel SP. The second light-emitting region EA2 of each sub-pixel SP may have the same planar shape as the first light-emitting region EA1 of the corresponding sub-pixel SP. The first light-emitting region EA1 and the second light-emitting region EA2 of each sub-pixel SP may have relatively long lengths in the second direction Y. For example, the first light-emitting region EA1 and the second light-emitting region EA2 of each sub-pixel SP may have a planar shape as a strip extending in the second direction Y. The second light-emitting region EA2 of each sub-pixel SP may be spaced apart from the first light-emitting region EA1 of the corresponding sub-pixel SP in the first direction X.

[0050] Each of the first luminous region EA1 and the second luminous region EA2 in each sub-pixel SP can have the same size as the first luminous region EA1 and the second luminous region EA2 in the adjacent sub-pixel SP. Each of the first luminous region EA1 and the second luminous region EA2 in the green sub-pixel G-SP can have the same size as the first luminous region EA1 and the second luminous region EA2 in the red sub-pixel R-SP, and each of the first luminous region EA1 and the second luminous region EA2 in the blue sub-pixel B-SP can have the same size as the first luminous region EA1 and the second luminous region EA2 in the green sub-pixel G-SP. Each of the red sub-pixel R-SP, green sub-pixel G-SP, and blue sub-pixel B-SP in each pixel region PA can have the same size as the red sub-pixel R-SP, green sub-pixel G-SP, and blue sub-pixel B-SP in the adjacent pixel region PA.

[0051] The display panel DP may include an encapsulation structure 400 disposed on a first light-emitting device 301 and a second light-emitting device 302 in each sub-pixel SP. The encapsulation structure 400 can prevent damage to the first light-emitting device 301 and the second light-emitting device 302 in each sub-pixel SP due to external impact and moisture. For example, the first light-emitting device 301 and the second light-emitting device 302 of each sub-pixel SP can be completely covered by the encapsulation structure 400. The encapsulation structure 400 may include a region overlapping with a first light-emitting region EA1 of each sub-pixel SP, a region overlapping with a second light-emitting region EA2 of each sub-pixel SP, and a region overlapping with a non-light-emitting region. The encapsulation structure 400 may have a multi-layer structure. For example, the encapsulation structure 400 may include a first encapsulation layer 410, a second encapsulation layer 420, and a third encapsulation layer 430 stacked sequentially. The first encapsulation layer 410, the second encapsulation layer 420, and the third encapsulation layer 430 may contain insulating material. The second encapsulation layer 420 may have higher fluidity than the first encapsulation layer 410 and the third encapsulation layer 430. For example, the first encapsulation layer 410 and the third encapsulation layer 430 can be inorganic encapsulation layers made of inorganic insulating materials, and the second encapsulation layer 420 can be an organic encapsulation layer made of organic insulating materials. The thickness difference caused by the first light-emitting device 301 and the second light-emitting device 302 of each sub-pixel SP can be eliminated by the second encapsulation layer 420. For example, the upper surface of the encapsulation structure 400 opposite to the device substrate 100 can be flat.

[0052] An optical structure OS can be disposed on the display panel DP. The travel paths of the first light L1 emitted from the first light-emitting device 301 of each sub-pixel SP and the second light L2 emitted from the second light-emitting device 302 of each sub-pixel SP can be adjusted by the optical structure OS. For example, the optical structure OS may include a barrier structure 500 disposed on the encapsulation structure 400 of the display panel DP. The barrier structure 500 can restrict the travel directions of the first light L1 and the second light L2 emitted from each sub-pixel SP. The barrier structure 500 may have a multi-layer structure. For example, the barrier structure 500 may have a stacked structure of a lower barrier pattern 510 and an upper barrier pattern 520.

[0053] The lower barrier pattern 510 may be disposed close to the upper surface of the package structure 400. For example, the lower barrier pattern 510 may be in direct contact with the upper surface of the package structure 400. The lower barrier pattern 510 may contain a material capable of blocking light. The lower barrier pattern 510 may contain a material with low reflectivity. For example, the lower barrier pattern 510 may contain a black dye, such as carbon black.

[0054] The lower barrier pattern 510 may include a lower opening 510h. Each lower opening 510h may overlap with one sub-pixel of the sub-pixel SP. Therefore, in a display device according to an embodiment of the present disclosure, a second light L2 emitted from a second light-emitting region EA2 of each sub-pixel SP may pass through the same lower opening 510h as the first light L1 emitted from a first light-emitting region EA1 of the corresponding sub-pixel SP.

[0055] The lower opening 510h on each sub-pixel SP may overlap with the region disposed between the first light-emitting region EA1 and the second light-emitting region EA2 of the corresponding sub-pixel SP. Each of the first light-emitting region EA1 and the second light-emitting region EA2 in each sub-pixel SP may include a region overlapping with one of the lower openings 510h and a region disposed outside the lower opening 510h. For example, the lower opening 510h of each sub-pixel SP may overlap with the portion of the first light-emitting region EA1 in the corresponding sub-pixel SP that is located near the second light-emitting region EA2 and the portion of the second light-emitting region EA2 in the corresponding sub-pixel SP that is located near the first light-emitting region EA1.

[0056] The first light-emitting area EA1 of each sub-pixel SP can be configured to be closer to the passenger seat PS than the second light-emitting area EA2 of the corresponding sub-pixel SP. The second light-emitting area EA2 of each sub-pixel SP can be configured to be closer to the driver seat DS than the first light-emitting area EA1 of the corresponding sub-pixel SP. Therefore, in the display device according to the embodiment of the present disclosure, the first light L1 emitted from the first light-emitting area EA1 of each sub-pixel SP can travel through one of the lower openings 510h in the direction of the driver seat DS, and the second light L2 emitted from the second light-emitting area EA2 of each sub-pixel SP can travel through one of the lower openings 510h in the direction of the passenger seat PS.

[0057] A portion of the first light-emitting region EA1 and a portion of the second light-emitting region EA2 disposed outside the lower opening 510h in each sub-pixel SP can overlap with the lower barrier pattern 510. For example, the portion of the first light-emitting region EA1 in each sub-pixel SP that is away from the second light-emitting region EA2 and the portion of the second light-emitting region EA2 in each sub-pixel SP that is away from the first light-emitting region EA1 can overlap with the lower barrier pattern 510. Therefore, in the display device according to an embodiment of the present invention, light emitted from the first light-emitting region EA1 of each sub-pixel SP toward the passenger seat PS and light emitted from the second light-emitting region EA2 of each sub-pixel SP toward the driver seat DS can be initially blocked by the lower barrier pattern 510.

[0058] The lower opening 510h of each sub-pixel SP can have a planar shape corresponding to the first light-emitting region EA1 and the second light-emitting region EA2 defined in the corresponding sub-pixel SP. For example, the planar shape of the lower opening 510h on each sub-pixel SP can have a strip extending in the second direction Y.

[0059] An upper barrier pattern 520 may be disposed on a lower barrier pattern 510. The upper barrier pattern 520 may be spaced apart from the lower barrier pattern 510. For example, the optical structure OS may include an optical insulating layer 600 covering the lower barrier pattern 510. The optical insulating layer 600 may contain a transparent material. The optical insulating layer 600 may have relatively high fluidity. For example, the optical insulating layer 600 may be an organic insulating layer made of an organic insulating material. The optical insulating layer 600 may extend over a first light-emitting region EA1 and a second light-emitting region EA2 of each sub-pixel SP. For example, the lower opening 510h of the lower barrier pattern 510 may be filled by the optical insulating layer 600. The thickness difference caused by the lower barrier pattern 510 can be eliminated by the optical insulating layer 600. For example, the upper surface of the optical insulating layer 600 opposite to the display panel DP may be flat.

[0060] The first light L1 and the second light L2, passing through the lower opening 510h of each sub-pixel SP, can be emitted through the optical insulating layer 600. Therefore, in the display device according to the embodiment of the present disclosure, the optical distance of the first light L1 and the optical distance of the second light L2 emitted from each sub-pixel SP can be proportional to the thickness of the optical insulating layer 600. Therefore, in the display device according to the embodiment of the present disclosure, the optical distance of the first light L1 and the optical distance of the second light L2 emitted from each sub-pixel SP can be sufficiently ensured by the optical insulating layer 600.

[0061] The upper barrier pattern 520 can be disposed on the upper surface of the optical insulating layer 600. The upper barrier pattern 520 can be disposed close to the upper surface of the optical insulating layer 600. For example, the upper barrier pattern 520 can be in direct contact with the upper surface of the optical insulating layer 600. The upper barrier pattern 520 can contain a material capable of blocking light. For example, the upper barrier pattern 520 can contain a black dye, such as carbon black. The upper barrier pattern 520 can contain the same material as the lower barrier pattern 510.

[0062] The upper barrier pattern 520 may include an upper opening 520h. Each upper opening 520h may overlap with one lower opening 510h. For example, the first light-emitting region EA1 and the second light-emitting region EA2 of each sub-pixel SP may overlap with one upper opening 520h. Therefore, in the display device according to an embodiment of the present disclosure, the second light L2 passing through the lower opening 510h of each sub-pixel SP may pass through the same upper opening 520h as the first light L1 passing through the lower opening 510h of the corresponding sub-pixel SP. Therefore, in the display device according to an embodiment of the present disclosure, the travel direction of the first light L1 emitted from each sub-pixel SP and the travel direction of the second light L2 emitted from each sub-pixel SP may be limited by the lower barrier pattern 510 and the upper barrier pattern 520.

[0063] The plane of the upper opening 520h on each sub-pixel SP can have a shape corresponding to the plane of the lower opening 510h on the corresponding sub-pixel SP. For example, the plane of the upper opening 520h on each sub-pixel SP can have a strip extending in the second direction Y. In the plan view, the center of the upper opening 520h on each sub-pixel SP can coincide with the center of the lower opening 510h on the corresponding sub-pixel SP. The upper opening 520h on each sub-pixel SP can have a smaller size than the lower opening 510h on the corresponding sub-pixel SP. For example, the upper opening 520h on each sub-pixel SP can be disposed within the lower opening 510h on the corresponding sub-pixel SP. Therefore, in the display device according to the embodiments of the present disclosure, a portion of the light passing through the lower opening 510h of each sub-pixel SP can be blocked by the upper barrier pattern 520.

[0064] The center of the first light-emitting region EA1 and the center of the second light-emitting region EA2 defined in each sub-pixel SP can be disposed within the lower opening 510h of the corresponding sub-pixel SP. The upper barrier pattern 520 can overlap with the center of the first light-emitting region EA1 and the center of the second light-emitting region EA2 defined in each sub-pixel SP. That is, in the display device according to the embodiment of the present disclosure, light emitted from the first light-emitting region EA1 of each sub-pixel SP in a direction perpendicular to the upper surface of the device substrate 100 and light emitted from the second light-emitting region EA2 of each sub-pixel SP in a direction perpendicular to the upper surface of the device substrate 100 can be blocked by the upper barrier pattern 520. Therefore, in the display device according to the embodiment of the present disclosure, the first light L1 emitted from the first light-emitting region EA1 of each sub-pixel SP cannot be recognized by the passenger sitting in the passenger seat PS, and the second light L2 emitted from the second light-emitting region EA2 of each sub-pixel SP cannot be recognized by the driver sitting in the driver seat DS. Therefore, in the display device according to the embodiment of the present disclosure, the visibility of the first light L1 of each sub-pixel SP to the first image and the visibility of the second light L2 of each sub-pixel SP to the second image can be improved. Furthermore, in the display device according to the embodiments of the present disclosure, driver's visual distraction caused by the second image can be prevented.

[0065] The optical structure OS may include optical lenses 700 disposed on the upper barrier pattern 520. Each optical lens 700 may overlap with one of the upper openings 520h. For example, the first light-emitting region EA1 and the second light-emitting region EA2 of each sub-pixel SP may overlap with the optical lens 700. The optical lens 700 of each sub-pixel SP may have a planar shape corresponding to the upper opening 520h of the corresponding sub-pixel SP. For example, the planar shape of the optical lens 700 on each sub-pixel SP may have a stripe extending in the second direction Y.

[0066] The surface of each optical lens 700 opposite to the device substrate 100 may have a convex shape in the direction opposite to the device substrate 100. For example, the cross-section of each optical lens 700 in the first direction X may have a semi-circular shape that convexes in the direction opposite to the device substrate 100. Therefore, in the display device according to the embodiment of the present disclosure, each optical lens of the optical lenses 700 can be used as a convex lens. For example, in the display device according to the embodiment of the present disclosure, the first light L1 and the second light L2 passing through the upper opening 520h of each sub-pixel SP can be focused by the optical lens 700 disposed on the corresponding sub-pixel SP. Therefore, in the display device according to the embodiment of the present disclosure, the quality of the first image generated by the first light L1 emitted from each sub-pixel SP and the quality of the second image generated by the second light L2 emitted from each sub-pixel SP can be improved.

[0067] The optical lens 700 of each sub-pixel SP can have a larger size than the upper opening 520h of the corresponding sub-pixel SP. For example, the upper opening 520h of each sub-pixel SP can be filled by the optical lens 700 of the corresponding sub-pixel SP. The optical lens 700 of each sub-pixel SP can be in direct contact with the upper surface of the optical insulating layer 600 within the upper opening 520h of the corresponding sub-pixel SP. The edge of the optical lens 700 on each sub-pixel SP can overlap with the upper barrier pattern 520. Therefore, in the display device according to the embodiments of the present disclosure, the light extraction efficiency of the first light L1 and the second light L2 emitted from each sub-pixel SP can be improved. The size of the optical lens 700 on each sub-pixel SP can be smaller than the size of the lower opening 510h on the corresponding sub-pixel SP.

[0068] In the planar view, the lens center point 700c of the optical lens 700 on each sub-pixel SP can coincide with the center of the upper opening 520h on the corresponding sub-pixel SP. For example, a virtual center line VC passing through the lens center point 700c of each sub-pixel SP in the second direction Y can be disposed in the first direction X between the first light-emitting area EA1 and the second light-emitting area EA2 of the corresponding sub-pixel SP. The distance between the virtual center line VC and the second light-emitting area EA2 of each sub-pixel SP can be the same as the distance between the first light-emitting area EA1 and the virtual center line VC of the corresponding sub-pixel SP. For example, the plane of the upper opening 520h on each sub-pixel SP can have a shape symmetrical with respect to the virtual center line VC of the corresponding sub-pixel SP. Therefore, in the display device according to the embodiments of the present disclosure, quality differences between the first image generated by the first light L1 emitted from each sub-pixel SP and the second image generated by the second light L2 emitted from each sub-pixel SP can be prevented.

[0069] The optical structure OS may include a lens planarization layer 800 disposed on the optical lens 700 of each sub-pixel SP. The lens planarization layer 800 can prevent damage to the optical lens 700 on each sub-pixel due to external impact. For example, the optical lens 700 of each sub-pixel SP can be completely covered by the lens planarization layer 800. The lens planarization layer 800 may extend on the upper surface of the upper barrier pattern 520 opposite to the device substrate 100. For example, the lens planarization layer 800 may include regions overlapping with the optical lens 700 of each sub-pixel SP and regions overlapping with the upper barrier pattern 520. The upper surface of the upper barrier pattern 520 opposite to the device substrate 100 may be in direct contact with the lens planarization layer 800. For example, the lens planarization layer 800 may be in direct contact with the surface of each optical lens 700 having a convex shape.

[0070] The lens planarization layer 800 may comprise an insulating material. For example, the lens planarization layer 800 may be an organic insulating layer made of an organic insulating material. The thickness difference caused by the optical lens 700 of each sub-pixel SP can be eliminated by the lens planarization layer 800. For example, the upper surface of the lens planarization layer 800 opposite to the device substrate 100 may be flat. The lens planarization layer 800 may have a refractive index smaller than that of the optical lens 700 of each sub-pixel SP. For example, in a display device according to an embodiment of the present disclosure, the first light L1 and the second light L2 passing through the optical lens 700 of each sub-pixel SP can be focused by the refractive index difference between the corresponding optical lens 700 and the lens planarization layer 800.

[0071] like Figure 3 As shown, the multiple pixel regions PA of the display panel DP may include a first pixel region PA1 and a second pixel region PA2, wherein the second pixel region PA2 is arranged side by side with the first pixel region PA1 in the second direction Y. The first pixel region PA1 may be arranged side by side in the first direction X. For example, the first pixel region PA1 and the second pixel region PA2 may be arranged repeatedly in the second direction Y. The second pixel region PA2 may be arranged side by side in the first direction X.

[0072] The arrangement of subpixels SP in each second pixel region PA2 can be symmetrical with the arrangement of subpixels SP in each first pixel region PA1. For example, in a display device according to an embodiment of the present disclosure, each of the first pixel region PA1 and the second pixel region PA2 may include a red subpixel R-SP, a green subpixel G-SP, and a blue subpixel B-SP. The green subpixel G-SP is arranged side by side with the red subpixel R-SP in the second direction Y, and the blue subpixel B-SP is spaced apart from the red subpixel R-SP and the green subpixel G-SP in the first direction X. The green subpixel G-SP of each first pixel region PA1 may be arranged in the second direction Y between the red subpixel R-SP of the corresponding first pixel region PA1 and the blue subpixel B-SP of a second pixel region in the second pixel region PA2. The red subpixel R-SP of each second pixel region PA2 may be arranged between the blue subpixel B-SP of a first pixel region in the first pixel region PA1 and the green subpixel G-SP of the corresponding second pixel region PA2. Therefore, in the display device according to the embodiments of the present disclosure, subpixels displaying different colors can be repeatedly arranged in the second direction Y. That is, in the display device according to the embodiments of the present disclosure, the distance between subpixels SP displaying the same color in the second direction Y can be constant. Therefore, in the display device according to the embodiments of the present disclosure, color changes caused by distance differences between subpixels SP displaying the same color in the second direction Y can be prevented.

[0073] The blue sub-pixel B-SP of each first pixel region PA1 can be alternately arranged with the red sub-pixel R-SP and green sub-pixel G-SP of the corresponding first pixel region PA1 in the first direction X. Similarly, the blue sub-pixel B-SP of each second pixel region PA2 can be alternately arranged with the red sub-pixel R-SP and green sub-pixel G-SP of the corresponding second pixel region PA2 in the first direction X. For example, each sub-pixel SP can display a different color than the sub-pixel SP arranged in the directions inclined to the first direction X and the second direction Y. Therefore, in the display device according to the embodiments of the present disclosure, the distance between sub-pixel SPs displaying the same color in the directions inclined to the first direction X and the second direction Y can be increased. Therefore, in the display device according to the embodiments of the present disclosure, unintended color mixing occurs due to the short distance between adjacent sub-pixel SPs in the directions inclined to the first direction X and the second direction Y.

[0074] In a display device according to an embodiment of the present disclosure, the length of the first light-emitting region EA1 on each sub-pixel SP in the second direction Y and the length of the second light-emitting region EA2 on each sub-pixel SP in the second direction Y can be increased. For example, in a display device according to an embodiment of the present disclosure, each of the first light-emitting regions EA1 and EA2 of the blue sub-pixel B-SP within each first pixel region PA1 may include the regions within the corresponding first pixel region PA1 facing the first light-emitting regions EA1 and EA2 of the red sub-pixel R-SP in the first direction X, and the regions within the corresponding first pixel region PA1 facing the first light-emitting regions EA1 and EA2 of the green sub-pixel G-SP in the first direction X. Similarly, each of the first light-emitting regions EA1 and EA2 of the blue sub-pixel B-SP within each second pixel region PA2 may include the regions within the corresponding second pixel region PA2 facing the first light-emitting regions EA1 and EA2 of the red sub-pixel R-SP in the first direction X, and the regions within the corresponding second pixel region PA2 facing the first light-emitting regions EA1 and EA2 of the green sub-pixel G-SP in the first direction X. The distance dx between adjacent sub-pixels SP in the second direction Y can be less than the length Ax of each of the first light-emitting regions EA1 and EA2 defined in the second direction Y within each sub-pixel SP. The first light-emitting regions EA1 and EA2 of the green sub-pixel G-SP within each first pixel region PA1 can include the regions within the corresponding first pixel region PA1 facing the first light-emitting regions EA1 and EA2 of the blue sub-pixel B-SP in the first direction X, and the regions within a second pixel region of the second pixel region PA2 facing the first light-emitting regions EA1 and EA2 of the red sub-pixel R-SP in the first direction X. The first light-emitting regions EA1 and EA2 of the red sub-pixel R-SP within each second pixel region PA2 can include the regions within a first pixel region of the first pixel region PA1 facing the first light-emitting regions EA1 and EA2 of the green sub-pixel G-SP in the first direction X, and the regions within the corresponding second pixel region PA2 facing the first light-emitting regions EA1 and EA2 of the blue sub-pixel B-SP in the first direction X. Therefore, in the display device according to the embodiments of the present disclosure, the amount of first light L1 emitted from the first light-emitting region EA1 of each sub-pixel SP and the amount of second light L2 emitted from the second light-emitting region EA2 of each sub-pixel SP can be increased.

[0075] Figure 6This is a view showing the relative brightness ① of first light L1 emitted from a first light-emitting region EA1 of each sub-pixel SP according to a viewing angle and the relative brightness ② of second light L2 emitted from a second light-emitting region EA2 of each sub-pixel SP according to a viewing angle in a display device according to an embodiment of the present disclosure. Here, the relative brightness ① of the first light L1 is based on the front brightness of the light emitted from the first light-emitting region EA1 of each sub-pixel SP measured without an optical structure OS, and the relative brightness ② of the second light L2 is based on the front brightness of the light emitted from the second light-emitting region EA2 of each sub-pixel SP measured without an optical structure OS.

[0076] Reference Figure 6 In the display device according to embodiments of the present disclosure, the first light L1 emitted from each sub-pixel SP cannot be detected at a viewing angle of 10° to 90°, and the second light L2 emitted from each sub-pixel SP cannot be detected at a viewing angle of -90° to -10°. That is, in the display device according to embodiments of the present disclosure, the first light L1 emitted from each sub-pixel SP cannot be recognized by a passenger sitting in the passenger seat PS, and the second light L2 emitted from each sub-pixel SP cannot be recognized by a driver sitting in the driver's seat DS. Therefore, in the display device according to embodiments of the present disclosure, the visibility of the first image realized by the first light L1 of each sub-pixel SP and the visibility of the second image realized by the second light L2 of each sub-pixel SP can be improved. Furthermore, in the display device according to embodiments of the present disclosure, driver visual distraction due to the second image can be prevented.

[0077] Reference Figure 6In the display device according to an embodiment of the present disclosure, the first light L1 emitted from each sub-pixel SP can have maximum brightness when the viewing angle is -30° to -50°, and the second light L2 emitted from each sub-pixel SP can have maximum brightness when the viewing angle is 30° to 50°. Therefore, in the display device according to an embodiment of the present disclosure, the first light L1, perceived by the driver sitting in the driver's seat DS, can have maximum brightness, and the second light L2, perceived by the passenger sitting in the passenger seat PS, can have maximum brightness. The maximum brightness of the first light L1 can be substantially the same as the front brightness of the light emitted from the first light-emitting area EA1 of each sub-pixel SP as measured without the optical structure OS, and the maximum brightness of the second light L2 can be substantially the same as the front brightness of the light emitted from the second light-emitting area EA2 of each sub-pixel as measured without the optical structure OS. Therefore, in the display device according to an embodiment of the present disclosure, the quality of the first image provided to the driver sitting in the driver's seat DS by the first light L1 of each sub-pixel SP and the quality of the second image provided to the passenger sitting in the passenger seat PS by the second light L2 of each sub-pixel SP can be improved.

[0078] Therefore, a display device according to an embodiment of the present disclosure may include: a display panel DP, the display panel DP including a first pixel region PA1 and a second pixel region PA2; and an optical lens 700 disposed on the display panel DP, wherein each of the first pixel region PA1 and the second pixel region PA2 may include a sub-pixel SP displaying a different color, wherein each sub-pixel SP may include a first light-emitting region EA1 and a second light-emitting region EA2 disposed side-by-side with the first light-emitting region EA1 in a first direction X, wherein the first light-emitting region EA1 and the second light-emitting region EA2 of each sub-pixel SP may overlap with one of the optical lenses in the optical lens 700, wherein each optical lens 700 may have a semi-circular cross-section in the first direction X, wherein each second pixel region PA2 may be disposed side-by-side with one of the first pixel regions PA1 in the first pixel region PA1 in a second direction Y, and wherein the arrangement of the sub-pixels SP in each second pixel region PA2 may be symmetrical with respect to the arrangement of the sub-pixels SP in each first pixel region PA1 in the second direction Y. Therefore, in the display device according to the embodiments of the present disclosure, the first light L1 emitted from the first light-emitting area EA1 of each sub-pixel SP cannot be recognized by the passenger sitting in the passenger seat PS, and the second light L2 emitted from the second light-emitting area EA2 of each sub-pixel SP cannot be recognized by the driver sitting in the driver seat DS. Furthermore, the quality of the first image generated by the first light L1 of each sub-pixel SP and the quality of the second image generated by the second light L2 of each sub-pixel SP can be improved. Therefore, in the display device according to the embodiments of the present disclosure, the visibility of the first image and the second image can be improved, and driver visual distraction caused by the second image can be prevented. Moreover, in the display device according to the embodiments of the present disclosure, low-power operation can be performed, and power consumption can be reduced without compromising the quality of the first and second images.

[0079] The display device according to embodiments of the present disclosure is described as having each of driving circuits DC1 and DC2 consisting of a first thin-film transistor TR1, a second thin-film transistor TR2, and a storage capacitor Cst. However, in a display device according to another embodiment of the present disclosure, each of driving circuits DC1 and DC2 may include a driving thin-film transistor and at least one switching thin-film transistor. For example, in a display device according to another embodiment of the present disclosure, each of driving circuits DC1 and DC2 may include a third thin-film transistor to initialize the storage capacitor Cst according to a gate signal. The third thin-film transistor includes a third semiconductor pattern, a third gate, a third drain, and a third source. For example, the third gate may be electrically connected to a gate line GL, and the third drain may be electrically connected to an initial line for initializing the storage capacitor Cst by applying a signal. The third semiconductor pattern may include a third drain region, a third source region, and a third channel region, the third drain region being electrically connected to a third drain, the third source region being electrically connected to a third source, and the third channel region being disposed between the third drain region and the third source region. According to a signal applied to the third gate, the third source may be electrically connected to the third drain through the third channel region of the third semiconductor pattern. Therefore, in a display device according to another embodiment of the present disclosure, the degree of freedom in configuring each of the drive circuits DC1 and DC2 can be improved.

[0080] In the display device according to embodiments of the present disclosure, the positions and electrical connections of the first drain, first source, second drain 225, and second source 227 in each driving circuit DC1 and driving circuit DC2 can vary depending on the configuration of the corresponding driving circuit DC1 and driving circuit DC2 and / or the type of the corresponding thin-film transistor TR1 and thin-film transistor TR2. For example, in the display device according to another embodiment of the present disclosure, the second gate 223 can be electrically connected to the first drain. Therefore, in the display device according to another embodiment of the present disclosure, the degree of freedom in the configuration of each driving circuit DC1 and driving circuit DC2 and the type of each thin-film transistor TR1 and thin-film transistor TR2 can be improved.

[0081] The display device according to an embodiment of the present disclosure is described as having a display panel DP disposed only between the driver's seat DS and the passenger seat PS. However, in a display device according to another embodiment of the present disclosure, the display panel DP and the optical structure OS can extend in a first direction X. For example, in a display device according to another embodiment of the present disclosure, the display panel DP and the optical structure OS may include a region disposed in front of the driver's seat DS, a region disposed between the driver's seat DS and the passenger seat PS, and a region disposed in front of the passenger seat PS. The display panel DP may have an integrated type, wherein the region disposed between the driver's seat DS and the passenger seat PS is continuous with the region disposed in front of the driver's seat DS and the region disposed in front of the passenger seat PS. Therefore, in a display device according to another embodiment of the present disclosure, the degree of freedom in the position and shape of the display panel DP can be improved.

[0082] In a display device according to another embodiment of the present disclosure, multiple display panels DP can be used. For example, in a display device according to another embodiment of the present disclosure, the display panels DP may include a first display panel mounted in front of the driver's seat DS, a second display panel mounted in front of the passenger seat PS, and a third display panel mounted between the driver's seat DS and the passenger seat PS. The first, second, and third display panels may have the same structure. The first, second, and third display panels may be separate from each other. For example, the first, second, and third display panels may display different images. Therefore, in a display device according to another embodiment of the present disclosure, different images can be provided to people located in various directions.

[0083] The display device according to an embodiment of the present disclosure is described as having a stripe extending in the second direction Y in the plane of each optical lens 700. However, in a display device according to another embodiment of the present disclosure, each optical lens 700 may overlap with a plurality of sub-pixels SP arranged side by side in the second direction Y. For example, in a display device according to another embodiment of the present disclosure, the optical lens 700 may extend in the second direction Y, such as... Figure 7As shown. An optical lens 700 overlapping at least one sub-pixel SP in each second pixel region PA2 can also overlap at least one sub-pixel SP in a first pixel region PA1 adjacent in the second direction Y. For example, the optical lens 700 may include a first lens 701 and a second lens 702, which are repeatedly arranged in the first direction X. A red sub-pixel R-SP, a green sub-pixel G-SP in each first pixel region PA1, and a blue sub-pixel B-SP in each second pixel region PA2 can overlap with one of the first lenses in the first lens 701, and a blue sub-pixel B-SP in each first pixel region PA1, a red sub-pixel R-SP in each second pixel region PA2, and a green sub-pixel G-SP in each second pixel region PA2 can overlap with one of the second lenses in the second lens 702. Therefore, in a display device according to another embodiment of the present disclosure, the process of forming the optical lens 700 can be simplified. Therefore, in a display device according to another embodiment of the present disclosure, process efficiency can be improved.

[0084] The display device according to an embodiment of the present disclosure is described such that the lower surface of each optical lens 700 facing the device substrate 100 can directly contact the upper surface of the optical insulating layer 600 within the upper opening 520h of each sub-pixel SP. However, in a display device according to another embodiment of the present disclosure, at least one insulating layer may be disposed between the optical insulating layer 600 and the optical lens 700. For example, in a display device according to another embodiment of the present disclosure, the optical structure OS may include a lens passivation layer 710 covering the upper barrier pattern 520, such as... Figure 8 As shown. The optical lens 700 of each sub-pixel SP can be disposed on the lens passivation layer 710.

[0085] The lens passivation layer 710 may comprise an insulating material. The lens passivation layer 710 may comprise a material different from the optical insulating layer 600. For example, the lens passivation layer 710 may be an inorganic insulating layer made of an inorganic insulating material. Therefore, in a display device according to another embodiment of the present disclosure, the diffusion of moisture and / or oxygen moving through the optical insulating layer 600 can be blocked by the lens passivation layer 710. For example, in a display device according to another embodiment of the present disclosure, moisture and / or oxygen moving through the optical insulating layer 600 cannot penetrate the optical lens 700 through the lens passivation layer 710. Therefore, in a display device according to another embodiment of the present disclosure, deformation of the optical lens 700 due to the penetration of moisture and / or oxygen can be reduced.

[0086] The display device according to an embodiment of the present disclosure is described as having an upper barrier pattern 520 comprising the same material as the lower barrier pattern 510. However, in another embodiment of the display device according to the present disclosure, the upper barrier pattern 520 may comprise a different material than the lower barrier pattern 510. For example, in another embodiment of the display device according to the present disclosure, a touch sensor TS for sensing the touch of a user or tool may be disposed between the optical insulating layer 600 and the lens planarization layer 800 of the optical structure OS, such as... Figure 9 and Figure 10 As shown.

[0087] The touch sensor TS may include touch electrodes 910 and bridging electrodes 920 connected between the touch electrodes 910. Touch electrodes 910 and bridging electrodes 920 may contain conductive materials. Touch electrodes 910 and bridging electrodes 920 may contain materials capable of blocking light. For example, touch electrodes 910 and bridging electrodes 920 may contain metal. At least a portion of the bridging electrodes 920 may contain a different material than that of the touch electrodes 910. For example, at least a portion of the bridging electrodes 920 may be disposed on a different layer than that of the touch electrodes 910.

[0088] Touch electrodes 910 can be disposed between the optical insulating layer 600 and the lens planarization layer 800. For example, the lower surface of each touch electrode 910 facing the device substrate 100 can directly contact the upper surface of the optical insulating layer 600, and the upper surface of each touch electrode 910 opposite to the device substrate 100 can directly contact the lens planarization layer 800. Touch electrodes 910 may include touch openings 910h overlapping with the lower opening 510h of the lower barrier pattern 510 and the optical lens 700. For example, light passing through the lower opening 510h of each sub-pixel SP can be emitted through one of the touch openings 910h. That is, in a display device according to another embodiment of the present disclosure, touch electrodes 910 can be used as an upper barrier pattern. Therefore, in a display device according to another embodiment of the present disclosure, the process of forming an upper barrier pattern can be omitted by using the touch sensor TS. Therefore, in a display device according to another embodiment of the present disclosure, process efficiency can be improved.

[0089] Therefore, in the display device according to embodiments of the present disclosure, the image provided to a user located at an inclined position on the display panel by one of the light-emitting areas of each sub-pixel cannot be recognized by a person located in a different direction from the user, and the brightness of the light provided to the user by the light-emitting area of ​​each sub-pixel can be improved. Therefore, in the display device according to embodiments of the present disclosure, the quality of the image provided to a user located at an inclined position on the display panel can be improved, and accidents caused by distraction of the viewer's line of sight by people around the user can be prevented. Therefore, in the display device according to embodiments of the present disclosure, low-power operation can be performed, and power consumption can be reduced.
