[0007] A display device according to the technical concept of the present invention for achieving the aforementioned problem includes an element substrate. A bank insulating film and a first light-emitting element are located on the element substrate. The bank insulating film defines a first light-emitting region within the pixel region.

The upper barrier pattern includes an upper opening that overlaps with the pixel lens. The first light-emitting region includes a region that overlaps with the upper opening and a region that overlaps with the upper barrier pattern. A virtual center line passing through the lens center point of the pixel lens in a direction perpendicular to the upper surface of the element substrate toward the upper barrier pattern is located outside the first light-emitting region.

[0013] Within the pixel region, a second light-emitting region may be defined by a bank insulating film. A second light-emitting element may be located between the element substrate and the upper barrier pattern. The second light-emitting element may overlap with the second light-emitting region of the pixel region. The second light-emitting region can embody the same color as the first light-emitting region. The second light-emitting region may include a region overlapping with the upper opening and a region overlapping with the upper barrier pattern. A virtual centerline may be located between the first and second light-emitting regions.

A first drive circuit and a second drive circuit may be located between the element substrate and the planarization film. The first drive circuit and the second drive circuit may be located within the pixel region. The first drive circuit may be electrically connected to the first light-emitting element. The second drive circuit may be isolated from the first drive circuit. The second drive circuit may be electrically connected to the second light-emitting element.

[0016] The second drive circuit may have the same configuration as the first drive circuit.

[0017] A display device according to the technical concept of the present invention for achieving the other problems to be solved, includes an element substrate. A bank insulating film is located on the element substrate. The bank insulating film defines a first light-emitting region and a second light-emitting region within each pixel region. An upper barrier pattern is located on the bank insulating film. The upper barrier pattern includes an upper opening. Each upper opening overlaps with one of the pixel regions. Pixel lenses are located on the upper barrier pattern. Each pixel lens overlaps with one of the upper openings. The lens center point of a pixel lens located on each pixel region is located between the first light-emitting region and the second light-emitting region of that pixel region in a first direction. The distance between adjacent pixel lenses in a second direction perpendicular to the first direction is the same as the distance between adjacent pixel lenses in the first direction. The distance between adjacent pixel lenses in directions inclined with respect to the first and second directions is smaller than the distance between adjacent pixel lenses in the second direction.

[0018] The second light-emitting region of each pixel region may have the same length in the first and second directions as the first light-emitting region of that pixel region.

[0019] A pixel region may include a first pixel region and a second pixel region. Each second pixel region may be positioned alongside each first pixel region in a direction tilted with respect to the first direction and the second direction. Each second pixel region may represent a different color from each first pixel region.

[0020] The aforementioned pixel region may include a third pixel region. Each third pixel region may be located alongside each first pixel region in the second direction. Each third pixel region may embody the same color as each first pixel region.

[0021] The aforementioned pixel region may include a fourth pixel region. Each fourth pixel region may be located alongside each first pixel region in the first direction. Each fourth pixel region may embody a different color from each first and each second pixel region. [Effects of the Invention]

Mode for Carrying Out the Invention

[0024] Details regarding the object, technical configuration, and the resulting effects of this specification will be more clearly understood from the following detailed description with reference to the drawings showing the embodiments of this specification. Here, the embodiments of this specification are provided to fully convey the technical idea of this specification to those skilled in the art, so this specification can be embodied in other forms without being limited to the embodiments described below.

[0025] Also, parts denoted by the same reference numerals throughout the specification mean the same components, and in the drawings, the lengths and thicknesses of layers or regions may be exaggerated for the sake of convenience. Further, when the first component is described as being "above" the second component, it includes not only the case where the first component is located directly above and in contact with the second component, but also the case where a third component is located between the first component and the second component.

[0026] Here, terms such as "first," "second," etc., are used to describe various components and to distinguish one component from others. However, within the scope that does not deviate from the technical concept of this specification, the first and second components may be arbitrarily named at the convenience of those skilled in the art.

[0027] The terms used in this specification are used solely to describe specific embodiments and are not intended to limit the technical ideas of this specification. For example, a singular representation of a component includes multiple components unless the context clearly indicates only singular components. Furthermore, terms such as "includes" or "has" in this specification are intended to specify the presence of features, figures, stages, operations, components, parts, or combinations thereof described in the specification, and should not be understood to preemptively exclude the possibility of the presence or addition of one or more other features, figures, stages, operations, components, parts, or combinations thereof.

[0028] Furthermore, unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as those generally understood by a person of ordinary skill in the art to which this specification pertains. Terms such as those defined in commonly used dictionaries should be interpreted to have a meaning consistent with their meaning in the context of the relevant art, and not to be interpreted in an ideal or overly formal sense unless explicitly defined herein.

[0029] (Examples) Figure 1 is a schematic diagram showing the location where a display device according to an embodiment of the present invention is installed.

[0030] Referring to Figure 1, the display device according to an embodiment of the present invention may include a display panel DP installed inside an automobile. The display panel DP can provide an image to the driver seated in the driver's seat DS and / or to the passenger seated in the passenger seat PS. For example, the display panel DP may be located between the driver's seat DS and the passenger seat PS. The driver seated in the driver's seat DS and the passenger seated in the passenger seat PS may be positioned in an inclined direction relative to the display panel DP.

[0031] The display panel DP can provide the passenger seated in the passenger seat PS with a different image than the driver seated in the driver's seat DS. For example, the display panel DP can provide the driver seated in the driver's seat DS with a first image containing information necessary for the operation of the vehicle, and the passenger seated in the passenger seat PS with a second image containing information unrelated to the operation of the vehicle.

[0032] The display panel DP can simultaneously display the first image and the second image. For example, the display panel DP can simultaneously emit a first light L1 for displaying the first image and a second light L2 for displaying the second image. The first light L1 does not have to travel in the direction of the passenger seat PS, and the second light L2 does not have to travel in the direction of the driver's seat DS. For example, the first image produced by the first light L1 is not recognized by the passenger sitting in the passenger seat PS, and the second image produced by the second light L2 is not recognized by the driver sitting in the driver's seat DS. Therefore, according to the embodiment of the present invention, the visibility of the first image and the visibility of the second image can be improved. Furthermore, according to the embodiment of the present invention, the display device can prevent the driver's gaze from being diverted by the second image. Therefore, according to the embodiment of the present invention, accidents caused by the driver's gaze being diverted while driving can be reduced.

[0033] Figure 2 is a plan view of the display panel DP of a display device according to an embodiment of the present invention. Figure 3 is an enlarged view of region K in Figure 2. Figure 4 is a diagram showing the circuit of a subpixel of a display device according to an embodiment of the present invention. Figure 5 is a diagram showing a cross-section taken along line II in Figure 3.

[0034] Referring to Figures 1 to 5, the display device according to an embodiment of the present invention may include a pixel region PA located within the display panel DP. The pixel region PA may be arranged in a matrix. For example, the pixel region PA may be located in a first direction X and a second direction Y perpendicular to the first direction X.

[0035] The first direction X may mean the direction from the driver's seat DS toward the passenger seat PS. The second direction Y may mean the direction perpendicular to the first direction X on the plane of the display panel DP. For example, the third direction Z, which is perpendicular to the first direction X and the second direction Y, may be the direction perpendicular to the plane of the display panel DP. Therefore, according to the display device of the embodiment of the present invention, the driver's seat DS and the passenger seat PS can be located on the plane of the display panel DP.

[0036] Each pixel region PA can embody a specific color. For example, the pixel region PA may include a red pixel region R-PA that embodies red, a green pixel region G-PA that embodies green, and a blue pixel region B-PA that embodies blue. Therefore, according to the display device of the present invention, a variety of color images can be embodied by the pixel region PA.

[0037] Each pixel region PA may include a first subpixel SP1 and a second subpixel SP2 positioned alongside the first subpixel SP1 in the first direction X. For example, the second subpixel SP2 of each pixel region PA may be located closer to the driver's seat DS than the first subpixel SP1 of that pixel region PA. The second subpixel SP2 of each pixel region PA may embody the same color as the first subpixel SP1 of that pixel region PA. For example, the first subpixel SP1 and the second subpixel SP2 of each blue pixel region B-PA may embody the color blue.

[0038] Within each sub-pixel SP1, SP2, there may be a drive circuit DC electrically connected to signal wiring (GL, DL, PL) and a light-emitting element 300 electrically connected to the drive circuit DC. The second sub-pixel SP2 of each pixel region PA can be formed using the same process as the first sub-pixel SP1 of the same pixel region PA. For example, the drive circuit DC of the second sub-pixel SP2 located within each pixel region PA may have the same configuration as the drive circuit DC of the first sub-pixel SP1 located within the same pixel region PA.

[0039] The signal wiring (GL, DL, PL) may include a gate line GL for applying a gate signal, a data line DL for applying a data signal, and a power supply line PL for supplying a power supply voltage. For example, the drive circuit DC can supply a drive current corresponding to the data signal to the light-emitting element 300 using the power supply voltage in response to the gate signal. The drive current supplied to the light-emitting element 300 by the drive circuit DC can be maintained for one frame. For example, the drive circuit DC may include a first thin-film transistor TR1, a second thin-film transistor TR2, and a storage capacitor Cst.

[0040] The first thin-film transistor TR1 can transmit the data signal to the second thin-film transistor TR2 in response to the gate signal. For example, the first thin-film transistor TR1 can function as a switching thin-film transistor. The first thin-film transistor TR1 may include a first semiconductor pattern, a first gate electrode, a first drain electrode, and a first source electrode. For example, the first gate electrode may be electrically connected to the gate line GL, and the first drain electrode may be electrically connected to the data line DL.

[0041] The second thin-film transistor TR2 can generate the drive current corresponding to the data signal. For example, the second thin-film transistor TR2 can function as a drive thin-film transistor. The second thin-film transistor TR2 may include a second semiconductor pattern 221, a second gate electrode 223, a second drain electrode 225, and a second source electrode 227. For example, the second gate electrode 223 may be electrically connected to the first source electrode, and the second drain electrode 225 may be electrically connected to the power supply voltage line PL.

[0042] The voltage of the signal applied to the second gate electrode 223 can be maintained for one frame by the storage capacitor Cst. The storage capacitor Cst may have a stacked structure of capacitor electrodes. For example, the storage capacitor Cst may have a structure in which a first capacitor electrode electrically connected to the second gate electrode 223 and a second capacitor electrode electrically connected to the second source electrode 227 are stacked.

[0043] The drive circuits DC of each subpixel SP1, SP2 may be supported by the element substrate 100. The element substrate 100 may include an insulating material. For example, the element substrate 100 may include glass or plastic. At least one insulating film (110, 120, 130, 140, 150) may be located on the element substrate 100 to prevent unnecessary electrical connections. For example, a buffer insulating film 110, a gate insulating film 120, an interlayer insulating film 130, an element planarization film 140, and a bank insulating film 150 may be located on the element substrate 100.

[0044] The buffer insulating film 110 can prevent contamination by the element substrate 100 during the process of forming the drive circuits DC for each subpixel SP1 and SP2. For example, the upper surface of the element substrate 100 facing the drive circuits DC for each subpixel SP1 and SP2 can be covered with the buffer insulating film 110. The drive circuits DC for each subpixel SP1 and SP2 can be located on the buffer insulating film 110.

[0045] The gate insulating film 120 may be located on the buffer insulating film 110. The second gate electrode 223 of each subpixel SP1, SP2 may be insulated from the second semiconductor pattern 221 of the subpixel SP1, SP2 by the gate insulating film 120. For example, the first semiconductor pattern and the second semiconductor pattern 221 of each subpixel SP1, SP2 may be covered with the gate insulating film 120.

[0046] The interlayer insulating film 130 may be located on the gate insulating film 120. The second drain electrode 225 and the second source electrode 227 of each subpixel SP1, SP2 may be insulated from the second gate electrode 223 of the subpixel SP1, SP2 by the interlayer insulating film 130. For example, the first gate electrode and the second gate electrode 223 of each subpixel SP1, SP2 located on the gate insulating film 120 may be covered by the interlayer insulating film 130.

[0047] The element planarization film 140 may be located on the interlayer insulating film 130. For example, the first drain electrode, first source electrode, second drain electrode 225, and second source electrode 227 of each subpixel SP1, SP2 located on the interlayer insulating film 130 may be covered with the element planarization film 140. Steps caused by the drive circuit DC of each subpixel SP1, SP2 can be eliminated by the element planarization film 140. For example, the upper surface of the element planarization film 140 facing the element substrate 100 may be flat. The element planarization film 140 may contain a material having higher fluidity than the buffer insulating film 110, the gate insulating film 120, and the interlayer insulating film 130. For example, the buffer insulating film 110, the gate insulating film 120, and the interlayer insulating film 130 may be inorganic insulating films made of inorganic insulating materials, and the element planarization film 140 may be an organic insulating film made of an organic insulating material.

[0048] The light-emitting element 300 of each subpixel SP1, SP2 may be located on the upper surface of the element planarization film 140. The light-emitting element 300 of each subpixel SP1, SP2 can emit light of a specific color. For example, the light-emitting element 300 of each subpixel SP1, SP2 may include a first electrode 310, a light-emitting unit 320, and a second electrode 330 that are sequentially stacked on the element planarization film 140.

[0049] The first electrode 310 and the second electrode 330 may contain conductive materials. The second electrode 330 may contain a different material from the first electrode 310. For example, the transmittance of the second electrode 330 may be higher than that of the first electrode 310. The first electrode 310 may contain a material having a higher reflectance than the second electrode 330. For example, the first electrode 310 may be a reflective electrode containing metals such as aluminum (Al) and silver (Ag), and the second electrode 330 may be a transparent electrode made of a transparent conductive material such as ITO and IZO.

[0050] 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 emission material layer (EML). The light-emitting unit 320 may have a multilayer structure. For example, the light-emitting unit 320 may further 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). The light generated by the light-emitting unit 320 may be emitted through the second electrode 330.

[0051] The first electrode 310 of each subpixel SP1, SP2 can be electrically connected to the drive circuit DC of the subpixel SP1, SP2. For example, the first electrode 310 of each subpixel SP1, SP2 can penetrate the element planarization film 140 and directly contact the second source electrode 227 of the subpixel SP1, SP2. The connection point between the second source electrode 227 and the first electrode 310 located within each subpixel SP1, SP2 can be covered by the bank insulating film 150.

[0052] The bank insulating film 150 located on the element planarization film 140 can partially expose the first electrodes 310 of each subpixel SP1, SP2. For example, the edges of the first electrodes 310 located within each subpixel SP1, SP2 can be covered with the bank insulating film 150. The bank insulating film 150 can contain an insulating material. For example, the first electrode 310 of the second subpixel SP2 can be insulated from the first electrode 310 of the first subpixel SP1 by the bank insulating film 150. Within each subpixel SP1, SP2, the light-emitting unit 320 can directly contact a portion of the first electrode 310 exposed by the bank insulating film 150. That is, according to the display device according to an embodiment of the present invention, the bank insulating film 150 can define light-emitting regions EA1, EA2 within each subpixel SP1, SP2 from which light is emitted. A portion of the element substrate 100 superimposed on the bank insulating film 150 can be defined as a non-light-emitting region from which light is not emitted. For example, according to an embodiment of the present invention, a first light-emitting region EA1 is defined within the first subpixel SP1 of each pixel region PA, a second light-emitting region EA2 is defined within the second subpixel SP2 of each pixel region PA, and the non-light-emitting region may be located between the first light-emitting region EA1 and the second light-emitting region EA2 of each pixel region PA.

[0053] The second light-emitting region EA2 of each pixel region PA may have the same size as the first light-emitting region EA1 of that pixel region PA. For example, the second light-emitting region EA2 of each pixel region PA may have the same length as the first light-emitting region EA1 of that pixel region PA in the first direction X and the second direction Y. The second light-emitting region EA2 of each pixel region PA may have the same planar shape as the first light-emitting region EA1 of that pixel region PA. For example, the plane of the first light-emitting region EA1 and the plane of the second light-emitting region EA2 defined within each pixel region PA may have a bar shape extending in the second direction Y.

[0054] The first light L1 for realizing the first image may be emitted from the first light-emitting region EA1 of each pixel region PA, and the second light L2 for realizing the second image may be emitted from the second light-emitting region EA2 of each pixel region PA. The second light L2 emitted from the second light-emitting region EA2 of each pixel region PA may exhibit the same color as the first light L1 emitted from the first light-emitting region EA1 of the same pixel region PA. For example, the light-emitting unit 320 located within the second light-emitting region EA2 of each pixel region PA may be formed simultaneously with the light-emitting unit 320 located within the first light-emitting region EA1 of the same pixel region PA.

[0055] The signal applied to the second electrode 330 located on the second subpixel SP2 of each pixel region PA may be the same as the signal applied to the second electrode 330 located on the first subpixel SP1 of the same pixel region PA. For example, the second electrode 330 located on the second subpixel SP2 of each pixel region PA may be electrically connected to the second electrode 330 located on the first subpixel SP1 of the same pixel region PA. The second electrode 330 located on the second subpixel SP2 of each pixel region PA may be in direct contact with the second electrode 330 located on the first subpixel SP1 of the same pixel region PA. The drive circuit DC located within the second subpixel SP2 of each pixel region PA may be isolated from the drive circuit DC located within the first subpixel SP1 of the same pixel region PA. Therefore, according to the display device according to the embodiment of the present invention, the brightness of the first light L1 emitted from the first light-emitting region EA1 of each pixel region PA can be adjusted by the data signal applied to the first sub-pixel SP1 of the pixel region PA, and the brightness of the second light L2 emitted from the second light-emitting region EA2 of each pixel region PA can be adjusted by the data signal applied to the second sub-pixel SP2 of the pixel region PA. Therefore, according to the display device according to the embodiment of the present invention, the first image embodied by the first light L1 emitted from the first light-emitting region EA1 of each pixel region PA can contain different information from the second image embodied by the second light L2 emitted from the second light-emitting region EA2 of each pixel region PA.

[0056] A sealing structure 400 may be located on the light-emitting element 300 of each pixel region PA. The sealing structure 400 can prevent damage to the light-emitting element 300 due to external impact and moisture. For example, the light-emitting element 300 of each pixel region PA may be completely covered by the sealing structure 400. The sealing structure 400 may include a region that overlaps with the first light-emitting region EA1 of each pixel region PA, a region that overlaps with the second light-emitting region EA2 of each pixel region PA, and a region that overlaps with the non-light-emitting region. The sealing structure 400 may have a multilayer structure. For example, the sealing structure 400 may include a first sealing layer 410, a second sealing layer 420, and a third sealing layer 430 stacked in order. The second sealing layer 420 may include a material having higher fluidity than the first sealing layer 410 and the third sealing layer 430. For example, the first sealing layer 410 and the third sealing layer 430 may be inorganic sealing layers containing an inorganic insulating material, and the second sealing layer 420 may be an organic sealing layer containing an organic insulating material. The step created by the light-emitting element 300 in each pixel region PA can be eliminated by the second sealing layer 420.

[0057] A barrier structure 500 may be located on the upper surface of the sealing structure 400 facing the element substrate 100. The barrier structure 500 may have a multilayer structure. For example, the barrier structure 500 may have a laminated structure of a lower barrier pattern 510 and an upper barrier pattern 520.

[0058] The lower barrier pattern 510 may be located close to the upper surface of the sealing structure 400. For example, the lower surface of the lower barrier pattern 510 facing the element substrate 100 may be in direct contact with the upper surface of the sealing structure 400. The lower barrier pattern 510 may include a material that can block light. For example, the lower barrier pattern 510 may include a black dye such as carbon black.

[0059] The lower barrier pattern 510 may include lower openings 510h. Each lower opening 510h may overlap with one of the pixel regions PA. Therefore, according to the display device according to an embodiment of the present invention, the second light L2 from the second light-emitting region EA2 of each pixel region PA can be emitted by passing through the same lower opening 510h as the first light L1 from the first light-emitting region EA1 of the same pixel region PA. Therefore, according to the display device according to an embodiment of the present invention, the direction of propagation of the first light L1 from the first light-emitting region EA1 of each pixel region PA and the direction of propagation of the second light L2 from the second light-emitting region EA2 of each pixel region PA can be primary restricted by the lower barrier pattern 510 including the lower openings 510h.

[0060] The lower opening 510h of each pixel region PA may be located between the first light-emitting region EA1 and the second light-emitting region EA2 defined within the pixel region PA. The first light-emitting region EA1 and the second light-emitting region EA2 of each pixel region PA may partially overlap with the lower opening 510h of the pixel region PA. For example, a portion of the first light-emitting region EA1 located near the second light-emitting region EA2 in each pixel region PA and a portion of the second light-emitting region EA2 located near the first light-emitting region EA1 may overlap with the lower opening 510h of the pixel region PA. The lower opening 510h of each pixel region PA may have a plane with a shape corresponding to the first light-emitting region EA1 and the second light-emitting region EA2 of the pixel region PA. For example, the plane of the lower opening 510h located on each pixel region PA may have a bar shape extending in the second direction Y. Therefore, according to the display device according to the embodiment of the present invention, the first light L1 emitted from the first light-emitting region EA1 of each pixel region PA can pass through one of the lower openings 510h and travel in the direction of the driver's seat DS, and the second light L2 emitted from the second light-emitting region EA2 of each pixel region PA can pass through one of the lower openings 510h and travel in the direction of the passenger seat PS.

[0061] A portion of the second light-emitting region EA2 that overlaps with the lower opening 510h of each pixel region PA may have the same size as a portion of the first light-emitting region EA1 that overlaps with the lower opening 510h of the pixel region PA. For example, the second light-emitting region EA2 of each pixel region PA may be symmetrical with the first light-emitting region EA1 of the pixel region PA with respect to the axis VC' passing through the lens center point 700c of the pixel lens 700 in the second direction Y shown in Figure 3. Therefore, according to the display device according to the embodiment of the present invention, the second image produced by the second light L2 of each pixel region PA can have the same quality as the first image produced by the first light L1 of the pixel region PA.

[0062] Each of the first light-emitting region EA1 and the second light-emitting region EA2 of each pixel region PA may include a region that does not overlap with the lower opening 510h of the pixel region PA. For example, a portion of the first light-emitting region EA1 located far from the second light-emitting region EA2 in each pixel region PA, and a portion of the second light-emitting region EA2 located far from the first light-emitting region EA1, may overlap with the lower barrier pattern 510. Therefore, according to the display device according to the embodiment of the present invention, the light emitted from the first light-emitting region EA1 of each pixel region PA toward the passenger seat PS and the light emitted from the second light-emitting region EA2 of each pixel region PA toward the driver's seat DS can be blocked by the lower barrier pattern 510. In other words, according to the display device according to the embodiment of the present invention, the first light L1 of each pixel region PA for the realization of the first image is not perceived by the passenger sitting in the passenger seat PS, and the second light L2 of each pixel region PA for the realization of the second image is not perceived by the driver sitting in the driver's seat DS. Therefore, according to the display device according to the embodiment of the present invention, the visibility of the first image provided to the driver seated in the driver's seat DS by the first light L1 and the visibility of the second image provided to the passenger seated in the passenger seat PS by the second light L2 can be improved. Furthermore, according to the display device according to the embodiment of the present invention, the driver's gaze can be prevented from being distracted by the second image.

[0063] The upper barrier pattern 520 may be located on the lower barrier pattern 510. The upper barrier pattern 520 may be separated from the lower barrier pattern 510. For example, the lower barrier pattern 510 may be covered with an optical insulating film 600, and the upper barrier pattern 520 may be located on the upper surface of the optical insulating film 600 facing the element substrate 100. The optical insulating film 600 may include a transparent material. For example, the optical insulating film 600 may include an organic insulating material. The first light-emitting region EA1 and the second light-emitting region EA2 of each pixel region PA may be superimposed on the optical insulating film 600. The optical insulating film 600 may extend over the non-light-emitting regions. For example, the lower opening 510h of the lower barrier pattern 510 may be filled with the optical insulating film 600.

[0064] The upper barrier pattern 520 may be located close to the upper surface of the optical insulating film 600. For example, the lower surface of the upper barrier pattern 520 facing the element substrate 100 may be in direct contact with the upper surface of the optical insulating film 600. The upper barrier pattern 520 may contain a material that can block light. For example, the upper barrier pattern 520 may contain a black dye such as carbon black. The upper barrier pattern 520 may contain the same material as the lower barrier pattern 510.

[0065] The upper barrier pattern 520 may include an upper opening 520h. The upper opening 520h may overlap with the lower opening 510h. For example, each upper opening 520h may overlap with one of the pixel regions PA. Therefore, according to the display device according to an embodiment of the present invention, the second light L2 emitted from the second light-emitting region EA2 of each pixel region PA can pass through the same upper opening 520h as the first light L1 emitted from the first light-emitting region EA1 of the same pixel region PA. In other words, according to the display device according to an embodiment of the present invention, the direction of propagation of the first light L1 by the first light-emitting region EA1 of each pixel region PA and the direction of propagation of the second light L2 by the second light-emitting region EA2 of each pixel region PA can be secondarily restricted by the upper barrier pattern 520.

[0066] The upper opening 520h of each pixel region PA may have a plane with a shape corresponding to the lower opening 510h of the pixel region PA. For example, the plane of the upper opening 520h located on each pixel region PA may have a bar shape extending in the second direction Y. The center of the upper opening 520h located on each pixel region PA may coincide with the center of the lower opening 510h located on the pixel region PA on the plane. The upper opening 520h of each pixel region PA may be smaller in size than the lower opening 510h of the pixel region PA. Therefore, according to the display device of the embodiment of the present invention, a portion of the light that has passed through the lower opening 510h of each pixel region PA can be blocked by the upper barrier pattern 520. For example, according to the display device according to an embodiment of the present invention, the centers of the first light-emitting region EA1 and the second light-emitting region EA2 defined within each pixel region PA are located outside the upper opening 520h located on the pixel region PA, and the light emitted from the first light-emitting region EA1 of each pixel region PA in a direction perpendicular to the upper surface of the element substrate 100 and the light emitted from the second light-emitting region EA2 of each pixel region PA in a direction perpendicular to the upper surface of the element substrate 100 can be partially blocked by the upper barrier pattern 520. Therefore, according to the display device according to an embodiment of the present invention, the visibility of the first image and the visibility of the second image can be effectively improved. Furthermore, according to the display device according to an embodiment of the present invention, the driver's gaze can be effectively prevented from being dispersed by the second image.

[0067] A pixel lens 700 may be located on the upper barrier pattern 520. Each pixel lens 700 may be superimposed on one of the upper openings 520h. For example, the first light L1 and the second light L2 that have passed through the upper opening 520h of each pixel region PA can be focused by the pixel lens 700 located on the pixel region PA. The pixel lens 700 located on each pixel region PA can function as a convex lens. For example, the surface of each pixel lens 700 facing the element substrate 100 may have a convex shape.

[0068] Each pixel lens 700 in a pixel region PA may have a plane with a shape corresponding to the upper opening 520h of the pixel region PA. For example, the plane of the pixel lens 700 located on each pixel region PA may have a bar shape extending in the second direction Y. Each pixel lens 700 in a pixel region PA may be larger than the upper opening 520h of the pixel region PA. For example, the upper opening 520h of each pixel region PA may be filled with the pixel lens 700 of the pixel region PA. The edges of the pixel lenses 700 located on each pixel region PA may overlap with the upper barrier pattern 520. Therefore, according to the display device of the embodiment of the present invention, the light extraction efficiency for the first light L1 and the second light L2 of each pixel region PA can be improved. Each pixel lens 700 in a pixel region PA may be smaller than the lower opening 510h of the pixel region PA.

[0069] The lens center point 700c of the pixel lens 700 located on each pixel region PA may coincide with the center of the upper opening 520h located on the pixel region PA in a plane. For example, a virtual center line VC passing through the lens center point 700c of each pixel region PA in a direction perpendicular to the upper surface of the element substrate 100 may be located between the first light-emitting region EA1 and the second light-emitting region EA2 of the pixel region PA in the first direction X. The plane of the upper opening 520h located on each pixel region PA may have a shape that is symmetrical with respect to an axis VC' passing through the lens center point 700c of the pixel lens 700 in the second direction Y. Therefore, according to the display device of the embodiment of the present invention, quality deviations between the first image and the second image due to the pixel lens 700 of each pixel region PA can be prevented.

[0070] A lens planarization film 800 may be located on the pixel lens 700 of each pixel region PA. The lens planarization film 800 can prevent damage to the pixel lens 700 located on each pixel region PA due to external impact. For example, the pixel lens 700 of each pixel region PA may be completely covered by the lens planarization film 800. The lens planarization film 800 may extend onto the upper surface of the upper barrier pattern 520 facing the element substrate 100. For example, the lens planarization film 800 may include a region overlapping the pixel lens 700 and a region overlapping the upper barrier pattern 520.

[0071] The lens planarization film 800 may contain an insulating material. For example, the lens planarization film 800 may contain an organic insulating material. The step caused by the pixel lens 700 can be eliminated by the lens planarization film 800. For example, the upper surface of the lens planarization film 800 facing the element substrate 100 may be flat. The lens planarization film 800 may have a refractive index smaller than that of the pixel lens 700 of each pixel region PA. For example, according to an embodiment of the present invention, light that has passed through the pixel lens 700 of each pixel region PA can be focused by the refractive index difference between the pixel lens 700 and the lens planarization film 800 of the pixel region PA. Figure 6 shows a brightness graph (1) of the first light L1 emitted from the first light emission region EA1 of each pixel region PA by viewing angle and a brightness graph (2) of the second light L2 emitted from the second light emission region EA2 of each pixel region PA by viewing angle in a display device according to an embodiment of the present invention.

[0072] Referring to Figure 6, according to the display device according to an embodiment of the present invention, the first light L1 of each pixel area PA can have maximum brightness at a viewing angle of -40° to -60°, and the second light L2 of each pixel area PA can have maximum brightness at a viewing angle of 40° to 60°. That is, according to the display device according to an embodiment of the present invention, the first light L1 recognized by the driver sitting in the driver's seat DS can have maximum brightness, and the second light L2 recognized by the passenger sitting in the passenger seat PS can have maximum brightness. Therefore, according to the display device according to an embodiment of the present invention, the quality of the first image provided to the driver sitting in the driver's seat DS by the first light L1 emitted from the first light-emitting area EA1 of each pixel area PA, and the quality of the second image provided to the passenger sitting in the passenger seat PS by the second light L2 emitted from the second light-emitting area EA2 of each pixel area PA can be improved.

[0073] Referring to Figure 6, according to the display device according to an embodiment of the present invention, the first light L1 of each pixel area PA does not need to be perceived at a viewing angle of 10° to 90°, and the second light L2 of each pixel area PA does not need to be perceived at a viewing angle of -90° to -10°. Therefore, according to the display device according to an embodiment of the present invention, the second light L2 emitted from the second light-emitting area EA2 of each pixel area PA is not perceived by the driver sitting in the driver's seat DS, and the first light L1 emitted from the first light-emitting area EA1 of each pixel area PA is not perceived by the passenger sitting in the passenger seat PS. Therefore, according to the display device according to an embodiment of the present invention, the visibility of the first image and the visibility of the second image can be improved. Furthermore, according to the display device according to an embodiment of the present invention, the driver's gaze can be prevented from being dispersed by the second image.

[0074] As a result, the display device according to an embodiment of the present invention includes the bank insulating film 150, the light-emitting element 300, the lower barrier pattern 510, the upper barrier pattern 520, and the pixel lens 700, wherein the bank insulating film 150 defines the first light-emitting region EA1 and the second light-emitting region EA2 within each pixel region PA, the lower barrier pattern 510 and the upper barrier pattern 520 each include openings 510h and 520h that overlap with the pixel region PA, each pixel lens 700 overlaps with one of the lower openings 510h of the lower barrier pattern 510 and one of the upper openings 520h of the upper barrier pattern 520, and the virtual center line VC passing through the lens center point 700c of each pixel lens 700 in a direction perpendicular to the upper surface of the element substrate 100 may be located between the first light-emitting region EA1 and the second light-emitting region EA2 of one of the pixel regions PA. Therefore, according to the display device according to the embodiment of the present invention, the direction of travel of the first light L1 emitted from the first light-emitting region EA1 defined within each pixel region PA is restricted to the direction of the driver's seat DS by the lower barrier pattern 510, the upper barrier pattern 520, and the pixel lens 700, and the direction of travel of the second light L2 emitted from the second light-emitting region EA2 defined within each pixel region PA is restricted to the direction of the passenger seat PS by the lower barrier pattern 510, the upper barrier pattern 520, and the pixel lens 700. In other words, according to the display device according to the technical concept of the present invention, the first light L1 for realizing the first image is not recognized by the passenger sitting in the passenger seat PS, and the second light L2 for realizing the second image is not recognized by the driver sitting in the driver's seat DS. Therefore, according to the display device according to the embodiment of the present invention, the visibility of the first image and the visibility of the second image can be improved, and the driver's gaze can not be dispersed by the second image.

[0075] Furthermore, according to the display device according to the embodiment of the present invention, the first light L1 emitted from the first light-emitting region EA1 of each pixel region PA has maximum brightness in the direction toward the driver's seat DS, and the second light L2 emitted from the second light-emitting region EA2 of each pixel region PA has maximum brightness in the direction toward the passenger seat PS. Therefore, according to the display device according to the embodiment of the present invention, the quality of the first image provided to the driver seated in the driver's seat DS by the first light L1 and the quality of the second image provided to the passenger seated in the passenger seat PS by the second light L2 can be improved. Therefore, according to the display device according to the embodiment of the present invention, the power consumption for realizing the first image and the power consumption for realizing the second image can be reduced. In other words, according to the display device according to the embodiment of the present invention, low power operation is possible, and power consumption can be reduced.

[0076] As shown in Figure 2, according to an embodiment of the present invention, the display panel DP may include a display area AA in which the pixel area PA is located, and a bezel area BZ located outside the display area AA. The bezel area BZ may extend along the edge of the display area AA. For example, the display area AA may be surrounded by the bezel area BZ. A gate driver GD electrically connected to the gate line GL, a data driver electrically connected to the data line DL, and a power supply unit electrically connected to the power supply voltage supply line PL may be located outside the display area AA. At least one of the gate driver GD, the data driver, and the power supply unit may be located on the bezel area BZ. For example, the display device according to an embodiment of the present invention may be a GIP (Gate In Panel) type display device in which the gate driver GD is formed on the bezel area BZ.

[0077] As shown in Figure 3, according to the display device of the present invention, each pixel region PA can embody a different color from the adjacent pixel region PA in the first direction X. For example, according to the display device of the present invention, the red pixel region R-PA, the green pixel region G-PA, and the blue pixel region B-PA can be repeatedly arranged in the first direction X. The pixel regions PA can be arranged offset from each other. For example, the arrangement of the pixel regions PA in the first direction X can have a zigzag shape. Each pixel region PA can embody the same color as the adjacent pixel region PA in the second direction Y. For example, according to the display device of the present invention, the pixel region PA can include a red pixel region R-PA located side by side in the second direction Y, a green pixel region G-PA located side by side with each red pixel region R-PA in a direction tilted with respect to the first direction X and the second direction Y, and a blue pixel region B-PA located side by side with each red pixel region R-PA in the first direction X.

[0078] The pixel regions PA may have a certain spacing in the first direction X and the second direction Y. For example, the distance dy between the pixel lenses 700 adjacent in the second direction Y may be the same as the distance dx between the pixel lenses 700 adjacent in the first direction X. The distance dd between the pixel lenses 700 adjacent in a direction inclined with respect to the first direction X and the second direction Y may be smaller than the distance dy between the pixel lenses 700 adjacent in the second direction Y. In other words, according to the display device of the embodiment of the present invention, the arrangement of the pixel regions PA having a zigzag shape can increase the distance between the pixel regions PA adjacent in the first direction X and the second direction Y. Therefore, according to the display device of the embodiment of the present invention, interference between the first light L1 of each pixel region PA and the second light L2 of the pixel region PA adjacent to that pixel region PA in the first direction X can be reduced. Therefore, according to the display device of the embodiment of the present invention, the quality of the first image by the first light L1 of each pixel region PA and the quality of the second image by the second light L2 of each pixel region PA can be effectively improved.

[0079] According to the display device according to an embodiment of the present invention, the size of the first light-emitting region EA1 and the size of the second light-emitting region EA2 defined within each pixel region PA can be increased. Therefore, according to the display device according to an embodiment of the present invention, the amount of the first light L1 provided to the driver seated in the driver's seat DS by the first light-emitting region EA1 of each pixel region PA and the amount of the second light L2 provided to the passenger seated in the passenger seat PS by the second light-emitting region EA2 of each pixel region PA can be increased. Therefore, according to the display device according to an embodiment of the present invention, the visibility of the first image by the first light L1 and the visibility of the second image by the second light L2 can be effectively improved.

[0080] The display device according to an embodiment of the present invention is described as having a drive circuit DC comprising the first thin-film transistor TR1, the second thin-film transistor TR2, and the storage capacitor Cst. However, according to another embodiment of the present invention, the drive circuit DC may include a drive thin-film transistor and at least one switching thin-film transistor. For example, according to another embodiment of the present invention, the drive circuit DC may further include a third thin-film transistor for initializing the storage capacitor Cst in response to a gate signal. The third thin-film transistor may include a third semiconductor pattern, a third gate electrode, a third drain electrode, and a third source electrode. For example, the third gate electrode may be electrically connected to the gate line GL, the third drain electrode may be electrically connected to an initialization line to which a signal for initializing the storage capacitor Cst is applied, and the third source electrode may be electrically connected to the storage capacitor Cst. Thus, according to another embodiment of the present invention, the degree of freedom for the configuration of the drive circuit DC can be increased.

[0081] In a display device according to an embodiment of the present invention, the first drain electrode, the first source electrode, the second drain electrode 225, and the second source electrode 227 of each drive circuit DC may have different positions and electrical connections depending on the configuration of the drive circuit DC and / or the type of the thin-film transistors TR1 and TR2. For example, in a display device according to another embodiment of the present invention, the second gate electrode 223 may be electrically connected to the first drain electrode. Therefore, in a display device according to another embodiment of the present invention, the degree of freedom for the configuration of each drive circuit DC and the type of each thin-film transistor TR1 and TR2 can be increased.

[0082] The display device according to an embodiment of the present invention is described as having the display panel DP located only between the driver's seat DS and the passenger seat PS. However, according to another embodiment of the present invention, the display panel DP may extend in the first direction X. For example, according to another embodiment of the present invention, an integrated display panel DP can be used that includes a region located in front of the driver's seat DS, a region located between the driver's seat DS and the passenger seat PS, and a region located in front of the passenger seat PS. Therefore, according to another embodiment of the present invention, the degree of freedom regarding the shape and position of the display panel DP can be improved.

[0083] The display device according to an embodiment of the present invention is described as including one display panel DP. However, according to a display device according to another embodiment of the present invention, a number of display panels DP may be used. For example, according to a display device according to another embodiment of the present invention, the number of display panels DP may include a first display panel installed in front of the driver's seat DS, a second display panel installed in front of the passenger seat PS, and a third display panel located between the driver's seat DS and the passenger seat PS. The first display panel, the second display panel, and the third display panel may have the same structure. The first display panel, the second display panel, and the third display panel may be separated from each other. For example, the first display panel, the second display panel, and the third display panel may embody different images from each other. Therefore, according to a display device according to another embodiment of the present invention, different images can be provided to viewers located in various directions.

[0084] In the embodiment of the present invention, the display device is described as having the lower surface of each pixel lens 700 facing the element substrate 100 in direct contact with the upper surface of the optical insulating film 600 within one of the upper openings 520h of the pixel region PA. However, in the display device according to another embodiment of the present invention, at least one insulating layer may be located between the optical insulating film 600 and the pixel lens 700. For example, as shown in Figure 7, in the display device according to another embodiment of the present invention, the upper barrier pattern 520 may be covered with a barrier protective film 701, and the pixel lens 700 of each pixel region may be located on the barrier protective film 701. The barrier protective film 701 may contain an insulating material. The barrier protective film 701 may contain a material different from the optical insulating film 600. For example, the barrier protective film 701 may be an inorganic insulating film made of an inorganic insulating material. Therefore, in the display device according to another embodiment of the present invention, deformation of the pixel lens 700 due to moisture and / or oxygen moving through the optical insulating film 600 can be prevented. Therefore, according to another embodiment of the present invention, a display device can prevent brightness deviations caused by differences in the shape of the pixel lens 700.

[0085] The display device according to an embodiment of the present invention is described as having a triangular arrangement on a plane of the adjacent red pixel region R-PA, the green pixel region G-PA, and the blue pixel region B-PA. However, according to a display device according to another embodiment of the present invention, the first light-emitting region EA1 and the second light-emitting region EA2 of each pixel region PA may share the pixel lens 700 located on the pixel region PA in various ways. For example, as shown in Figures 8 to 10, according to a display device according to another embodiment of the present invention, the lower opening 510h, the upper opening 520h, and the pixel lens 700 may each extend in the second direction Y, the pixel region PA may be located side by side in the first direction X and the second direction Y, and the first light-emitting region EA1 and the second light-emitting region EA2 of each pixel region PA may be located side by side in a direction inclined with respect to the first direction X and the second direction Y. That is, according to a display device according to another embodiment of the present invention, the second light-emitting region EA2 of each pixel region PA may be separated from the first light-emitting region EA1 of the pixel region PA in the first direction X and the second direction Y. Therefore, according to another embodiment of the present invention, the interference between the first light L1 of each pixel region PA and the second light L2 of a pixel region PA adjacent to the said pixel region PA can be effectively reduced without a decrease in resolution.

[0086] The display device according to an embodiment of the present invention is described as having the upper barrier pattern 520 containing the same material as the lower barrier pattern 510. However, according to a display device according to another embodiment of the present invention, the upper barrier pattern 520 may contain a different material from the lower barrier pattern 510. For example, as shown in Figures 11 and 12, according to a display device according to another embodiment of the present invention, a touch sensor TS for sensing the touch of a user or tool may be located between the optical insulating film 600 and the lens planarization film 800.

[0087] The touch sensor TS may include a touch electrode 910 and a bridge electrode 920 connecting the touch electrode 910 to each other. The touch electrode 910 and the bridge electrode 920 may be made of a conductive material. The touch electrode 910 and the bridge electrode 920 may be made of a material that can block light. For example, the touch electrode 910 and the bridge electrode 920 may be made of a metal. At least a portion of the bridge electrode 920 may be made of a material different from the touch electrode 910. For example, at least a portion of the bridge electrode 920 may be located on a different layer from the touch electrode 910.

[0088] The lower surface of each touch electrode 910 facing the element substrate 100 can directly contact the upper surface of the optical insulating film 600. For example, the touch electrode 910 may be located between the optical insulating film 600 and the lens planarization film 800. The touch electrode 910 may be located outside the first light-emitting region EA1 and the second light-emitting region EA2 defined within each pixel region PA. For example, the touch electrode 910 may be located within the non-light-emitting region. The edge of each pixel lens 700 may overlap with one of the touch electrodes 910. The touch electrode 910 may overlap with the lower barrier pattern 510. The direction of light propagation passing through each lower opening 510h can be restricted by the touch electrode 910. For example, according to another embodiment of the present invention, the touch electrode 910 can function as the upper barrier pattern. The space between the touch electrodes 910 can function as the upper opening 520h. That is, according to another embodiment of the present invention, the process of forming the upper barrier pattern can be omitted. Therefore, according to another embodiment of the present invention, the display device can improve process efficiency.

[0089] The display device according to an embodiment of the present invention is described as having each pixel region PA including the first light-emitting region EA1 and the second light-emitting region EA2. However, according to a display device according to another embodiment of the present invention, each pixel region PA may include one light-emitting region EA1, EA2. For example, as shown in Figures 13 and 14, according to a display device according to another embodiment of the present invention, the pixel region PA may include a first pixel region PA1 that includes only the first light-emitting region EA1 and a second pixel region PA2 that includes only the second light-emitting region EA2.

[0090] According to another embodiment of the present invention, the image represented by the first pixel area PA1 or the second pixel area PA2 can be provided to only one of the following: the driver seated in the driver's seat DS or the passenger seated in the passenger seat PS. For example, according to another embodiment of the present invention, the first image provided to the driver seated in the driver's seat DS may be represented by the first pixel area PA1, and the second image provided to the passenger seated in the passenger seat PS may be represented by the second pixel area PA2.

[0091] The first pixel region PA1 and the second pixel region PA2 can be repeatedly arranged in the first direction X. Therefore, according to the display device of another embodiment of the present invention, the brightness deviation between the first image and the second image can be prevented or reduced. Therefore, according to the display device of another embodiment of the present invention, the degree of freedom for the arrangement and configuration of the pixel region PA can be improved.
