[0084] FIG. 4 is a cross-sectional view of a display device according to one embodiment. For example, FIG. 4 may be a cross-sectional view of a portion of a pixel of FIG. 1.

[0085] As illustrated in FIG. 4, the display panel (100) of the display device (10) may include a substrate (SUB), a barrier layer (BR), a thin film transistor layer (TFTL), a light-emitting element layer (EMTL), and an encapsulation layer (ENC). On the substrate (SUB), the barrier layer (BR), the thin film transistor layer (TFTL), the light-emitting element layer (EMTL), and the encapsulation layer (ENC) may be arranged sequentially along a third direction (DR3).

[0086] The substrate (SUB) may be a rigid substrate or a flexible substrate capable of bending, folding, rolling, etc. The substrate (SUB) may be made of an insulating material such as glass, quartz, or polymer resin. Examples of polymeric materials include polyethersulfone (PES), polyacrylate (PA), polyarylate (PAR), polyetherimide (PEI), polyethylene napthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyallylate, polyimide (PI), polycarbonate (PC), cellulose triacetate (CAT), cellulose acetate propionate (CAP), or combinations thereof. Alternatively, the substrate (SUB) may include a metal material.

[0087] As illustrated in FIG. 4, a barrier layer (BR) may be disposed on a substrate (SUB). The barrier layer (BR) may be disposed on the entire surface of the substrate (SUB). The barrier layer (BR) may be a film to protect the transistors (T1-T8) of the thin-film transistor layer (TFTL) and the light-emitting layer (EL) of the light-emitting device layer (EMTL) from moisture penetrating through the substrate (SUB), which is susceptible to moisture permeability. The barrier layer (BR) may be composed of a plurality of alternately stacked inorganic films. For example, the barrier layer (BR) may be formed as a multilayer film (e.g., a first barrier layer (BR1) and a second barrier layer (BR2)) in which one or more inorganic films selected from a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, and an aluminum oxide layer are alternately stacked.

[0088] As illustrated in FIG. 4, a first pattern layer may be disposed on the barrier layer (BR). For example, a light-blocking layer (BML) may be disposed on the barrier layer (BR). The light-blocking layer (BML) may be disposed on the barrier layer (BR) to cover an overlapping region (e.g., a first channel region (CH1)) between the first gate electrode (GE1) and the first active layer (ACT1). In other words, the light-blocking layer (BML) may be disposed on the barrier layer (BR) to overlap with the channel region (CH1) of the first transistor (T1), which is the driving transistor. The light-blocking layer (BML) may be made of a metallic material such as, for example, chromium (Cr) or molybdenum (Mo), or black ink or black dye. Meanwhile, when the light-blocking layer (BML) is made of a metallic material, the light-blocking layer (BML) may be supplied with a static power source. Through this, the light-blocking layer (BML) is not electrically floating, and the electrical characteristics of the transistor on the light-blocking layer (BML) (e.g., the first transistor (T1)) can be stabilized.

[0089] As illustrated in FIG. 4, a buffer layer (BF) may be disposed on the light-blocking layer (BML). The buffer layer (BF) may be disposed on the entire surface of the substrate (SUB) including the barrier layer (BR). The buffer layer (BF) may be a film to protect the transistors (T1-T8) of the thin-film transistor layer (TFTL) and the light-emitting layer (EL) of the light-emitting element layer (EMTL) from moisture penetrating through the substrate (SUB), which is susceptible to moisture permeability. The buffer layer (BF) may be composed of a plurality of alternately stacked inorganic films. For example, the buffer layer (BF) may be formed as a multilayer film (e.g., a first buffer layer (BR1) and a second buffer layer (BR2)) in which one or more inorganic films selected from a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, and an aluminum oxide layer are alternately stacked.

[0090] A second pattern layer may be disposed on the buffer layer (BF). For example, a first active layer (ACT1) may be disposed on the barrier layer (BR). As illustrated in FIG. 4, the first active layer (ACT1) may include a first channel region (CH1) of a first transistor (T1), a second electrode (E12) of the first transistor (T1), a first channel region (CH1) of the first transistor (T1), a first electrode (E61) of the sixth transistor (T6), a second electrode (E62) of the sixth transistor (T6), and a sixth channel region (CH1) of the sixth transistor (T6). The first active layer (ACT1) may be an active layer made of Low Temperature Polycrystalline Silicon (LTPS).

[0091] A first gate insulating layer (GTI1) may be disposed on the second pattern layer. For example, as shown in FIG. 4, a first gate insulating layer (GTI1) may be disposed on the first active layer (ACT1). At this time, the first gate insulating layer (GTI1) may be disposed on the front surface of a substrate (SUB) including the first active layer (ACT1). The first gate insulating layer (GTI1) may include at least one of tetraethylorthosilicate (TEOS), silicon nitride (SiNx), and silicon oxide (SiO2). For example, the first gate insulating layer (GTI1) may have a double-film structure in which a silicon nitride film having a thickness of 40 nm and a tetraethylsilane film having a thickness of 80 nm are stacked in sequence.

[0092] A third pattern layer may be disposed on the first gate insulating layer (GTI1). For example, a second gate electrode (GE2), a first gate electrode (GE1), an eighth gate electrode (GE8), a light emission control line (EML), a fifth gate electrode (GE5), and a sixth gate electrode (GE6) may be disposed on the first gate insulating layer (GTI1). FIG. 4 illustrates an example in which the first gate electrode (GE1), the sixth gate electrode (GE6), and the light emission control line (EML) are disposed on the first gate insulating layer (GTI1). The first gate electrode (GE1) may be disposed on the first gate insulating layer (GTI1) so as to overlap with the first channel region (CH1) of the first active layer (ACT1). The sixth gate electrode (GE6) of the light emission control line (EML) may be disposed on the first gate insulating layer (GTI1) so as to overlap with the sixth channel region (CH6) of the first active layer (ACT1). The third pattern layer may comprise at least one of molybdenum (Mo), copper (Cu), aluminum, and titanium (Ti) and may be composed of a single layer or multiple layers. For example, the first gate electrode (GE1) may be composed of a triple film comprising a titanium film, an aluminum film, and a titanium film sequentially arranged along a third direction (DR3) on the first gate insulating layer (GTI1).

[0093] A second gate insulating layer (GTI2) may be disposed on the third pattern layer. For example, as shown in FIG. 4, a second gate insulating layer (GTI2) may be disposed on the first gate electrode (GE1), the sixth gate electrode (GE6), and the light emission control line (EML). In this case, the second gate insulating layer (GTI2) may be disposed on the front surface of a substrate (SUB) including the first gate electrode (GE1), the sixth gate electrode (GE6), and the light emission control line (EML). The second gate insulating layer (GTI2) may include the same material and structure as the aforementioned first gate insulating layer (GTI1).

[0094] A fourth pattern layer may be disposed on the second gate insulating layer (GTI2). For example, a fourth opposing gate electrode (GEb4), a third opposing gate electrode (GEb3), and a capacitor electrode (CPE) may be disposed on the second gate insulating layer (GTI2). FIG. 4 illustrates an example in which the capacitor electrode (CPE) and the third opposing gate electrode (GEb3) are disposed on the second gate insulating layer (GTI2). The capacitor electrode (CPE) may be disposed on the second gate insulating layer (GTI2) so as to overlap with the first gate electrode (GE1). A capacitor (Cst) may be formed between the capacitor electrode (CPE) and the first gate electrode (GE1). The fourth pattern layer may have the same material or structure as the aforementioned third pattern layer.

[0095] A first interlayer insulating layer (ITL1) may be disposed on the fourth pattern layer. For example, as shown in FIG. 4, a first interlayer insulating layer (ITL1) may be disposed on the capacitor electrode (CPE) and the third opposing gate electrode (GEb3). At this time, the first interlayer insulating layer (ITL1) may be disposed on the front surface of a substrate (SUB) including the capacitor electrode (CPE) and the third opposing gate electrode (GEb3). The first interlayer insulating layer (ITL1) may include an inorganic film, for example, a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer. Meanwhile, the first interlayer insulating layer (ITL1) may include a plurality of inorganic films.

[0096] A fifth pattern layer may be disposed on the first interlayer insulating layer (ITL1). For example, a second active layer (ACT2) may be disposed on the first interlayer insulating layer (ITL1). As illustrated in FIG. 4, the second active layer (ACT2) may be disposed on the first interlayer insulating layer (ITL1) so as to overlap with the third opposing gate electrode (GEb3). The second active layer (ACT2) may include the first electrode (E31) of the third transistor (T3), the second electrode (E32) of the third transistor (T3), and the third channel region (CH3) of the third transistor (T3). The third channel region (CH3) of the second active layer (ACT2) may overlap with the third opposing gate electrode (GEb3). The second active layer (ACT2) may be an oxide-based active layer. For example, the second active layer (ACT2) may be an oxide semiconductor comprising indium-gallium-zinc oxide (IGZO) or indium-gallium-zinc-tin oxide (IGZTO).

[0097] A third gate insulating layer (GTI3) may be disposed on the fifth pattern layer. For example, as shown in FIG. 4, a third gate insulating layer (GTI3) may be disposed on the second active layer (ACT2). The third gate insulating layer (GTI3) may be disposed on the front surface of the substrate (SUB) including the second active layer (ACT2). The third gate insulating layer (GTI3) may have the same material and structure as the first gate insulating layer (GTI1) described above.

[0098] A sixth pattern layer may be disposed on the third gate insulating layer (GTI3). For example, a fourth gate electrode (GE4) and a third gate electrode (GE3) may be disposed on the third gate insulating layer (GTI3). FIG. 4 illustrates an example in which the third gate electrode (GE3) is disposed on the third gate insulating layer (GTI3). The third gate electrode (GE3) may be disposed to overlap with the third channel region (CH3) of the second active layer (ACT2). The sixth pattern layer may have the same material or structure as the aforementioned third pattern layer.

[0099] A second interlayer insulating layer (ITL2) may be disposed on the sixth pattern layer. For example, as shown in FIG. 4, a second interlayer insulating layer (ITL2) may be disposed on the third gate electrode (GE3). The second interlayer insulating layer (ITL2) may be disposed on the front surface of a substrate (SUB) including the third gate electrode (GE3). The second interlayer insulating layer (ITL2) may have the same material and structure as the first interlayer insulating layer (ITL1) described above.

[0100] A seventh pattern layer may be disposed on the second interlayer insulating layer (ITL2). For example, a first initialization voltage line (VIL1), a third gate line (GIL), a data connection electrode (DCE), a first gate line (GWL), a second gate line (GCL), a gate connection electrode (GCE), an active connection electrode (ACE), a bias voltage line (VBL), a capacitor connection electrode (CCE), a lower pixel connection electrode (PCEa), a fourth gate line (EBL), and a second initialization voltage line (VIL2) may be disposed on the second interlayer insulating layer (ITL2). FIG. 4 illustrates an example in which a gate connection electrode (GCE), an active connection electrode (ACE), a bias voltage line (VBL), and a lower pixel connection electrode (PCEa) are disposed on the second interlayer insulating layer (ITL2). The lower pixel connection electrode (PCEa) can be connected to the second electrode (E62) of the sixth transistor (T6) through a first contact hole (CT1) penetrating the second interlayer insulation layer (ITL2), the third gate insulation layer (GTI3), the first interlayer insulation layer (ITL1), the second gate insulation layer (GTI2), and the first gate insulation layer (GTI1). The active connection electrode (ACE) can be connected to the second electrode (E11) of the first transistor (T1) and the first electrode (E61) of the sixth transistor (T6) through a second contact hole (CT2) penetrating the second interlayer insulation layer (ITL2), the third gate insulation layer (GTI3), the first interlayer insulation layer (ITL1), the second gate insulation layer (GTI2), and the first gate insulation layer (GTI1). Additionally, the active connection electrode (ACE) can be connected to the second electrode (E32) of the third transistor (T3) through a fifth contact hole (CT5) that penetrates the second interlayer insulating layer (ITL2) and the third gate insulating layer (GTI3).The gate connection electrode (GCE) can be connected to the first gate electrode (GE1) through a hole (40) in the second interlayer insulating layer (ITL2), the third gate insulating layer (GTI3), the first interlayer insulating layer (ITL1), and the capacitor electrode (CPE), and a third contact hole (CT3) penetrating the second gate insulating layer (GTI2). Additionally, the gate connection electrode (GCE) can be connected to the first electrode (E31) of the third transistor (T3) through a fourth contact hole (CT4) penetrating the second interlayer insulating layer (ITL2) and the third gate insulating layer (GTI3). The seventh pattern layer may have the same material or structure as the aforementioned third pattern layer.

[0101] A first planarization layer (VA1) may be disposed on the seventh pattern layer. For example, the first planarization layer (VA1) may be disposed on the gate connection electrode (GCE), the active connection electrode (ACE), the bias voltage line (VBL), and the lower pixel connection electrode (PCEa). The first planarization layer (VA1) may be disposed on the front surface of a substrate (SUB) including the gate connection electrode (GCE), the active connection electrode (ACE), the bias voltage line (VBL), and the lower pixel connection electrode (PCEa). The first planarization layer (VA1) may include an organic film such as an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0102] An eighth pattern layer may be disposed on the first flattening layer (VA1). For example, a first data line (DL1), a driving voltage line (VDL), and an upper pixel connection electrode (PCEb) may be disposed on the second interlayer insulating layer (ITL2). FIG. 4 illustrates an example in which the driving voltage line (VDL) and the upper pixel connection electrode (PCEb) are disposed on the first flattening layer (VA1). The upper pixel connection electrode (PCEb) may be connected to the lower pixel connection electrode (PCEa) through a sixth contact hole (CT6) penetrating the first flattening layer (VA1). The eighth pattern layer may have the same material or structure as the aforementioned third pattern layer.

[0103] A second flattening layer (VA2) may be disposed on the eighth pattern layer. For example, the second flattening layer (VA2) may be disposed on the driving voltage line (VDL) and the upper pixel connection electrode (PCEb). The second flattening layer (VA2) may be disposed on the front surface of the substrate (SUB) including the driving voltage line (VDL) and the upper pixel (PX) connection electrode (PCEb). The second flattening layer (VA2) may have the same material and structure as the aforementioned first flattening layer (VA1).

[0104] A ninth pattern layer may be disposed on the second flattening layer (VA2). For example, as shown in FIG. 4, a light-emitting element layer (EMTL) including the ninth pattern layer may be disposed on the second flattening layer (VA2). For example, as shown in FIG. 4, a pixel electrode (PE) may be disposed as the ninth pattern layer on the third flattening layer (VA3). The pixel electrode (PE) may be connected to an upper pixel connection electrode (PCEb) through a seventh contact hole (CT7) penetrating the second flattening layer (VA2).

[0105] The aforementioned light-emitting element layer (EMTL) may further include a light-emitting element (LEL) and a pixel definition layer (PDL) in addition to the aforementioned ninth pattern layer.

[0106] A light-emitting element (LEL) may include a pixel electrode (PE), a light-emitting layer (EL), and a common electrode (CM). The light-emitting region (EA) represents a region in which the pixel electrode (PE), the light-emitting layer (EL), and the common electrode (CM) are sequentially stacked, and holes from the pixel electrode (PE) and electrons from the common electrode (CM) combine with each other in the light-emitting layer to emit light. In this case, the pixel electrode (PE) may be the anode electrode (or first electrode) of the light-emitting element (LEL), and the common electrode (CM) may be the cathode electrode (or second electrode) of the light-emitting element (LEL).

[0107] In a top emission structure that emits light in the direction of the common electrode (CM) based on the light-emitting layer (EL), the pixel electrode (PE) may be formed as a single layer of molybdenum (Mo), titanium (Ti), copper (Cu), or aluminum (Al), or, to increase reflectivity, may be formed as a stacked structure of aluminum and titanium (Ti / Al / Ti), a stacked structure of aluminum and ITO (ITO / Al / ITO), an APC alloy, and a stacked structure of APC alloy and ITO (ITO / APC / ITO). The APC alloy is an alloy of silver (Ag), palladium (Pd), and copper (Cu).

[0108] The pixel defining layer (PDL) can serve to define the light-emitting regions (EA) of the pixels (PX). To this end, the pixel defining layer (PDL) can be positioned on the third planarization layer (VA3) to expose a portion of the pixel electrode (PE). The pixel defining layer (PDL) can cover the edges of the pixel electrode (PE). Meanwhile, the pixel defining layer (PDL) can be positioned within a seventh contact hole (CT7) penetrating the third planarization layer (VA3). As a result, the seventh contact hole (CT7) penetrating the third planarization layer (VA3) can be filled by the pixel defining layer (PDL). The pixel defining layer (PDL) can be formed from an organic film such as an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0109] As shown in FIG. 4, a spacer (SPC) may be placed on the pixel definition layer (PDL). The spacer (SPC) may serve to support the mask during the process of manufacturing the light-emitting layer (EL). The spacer (SPC) may be formed from an organic film such as an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0110] An emitting layer (EL) may be formed on the pixel electrode (PE). The emitting layer (EL) may include an organic material and emit a predetermined color. For example, the emitting layer (EL) may include a hole transporting layer, an organic material layer, and an electron transporting layer. The organic material layer may include a host and a dopant. The organic material layer may include a material that emits a predetermined light and may be formed using a phosphorescent material or a fluorescent material.

[0111] The aforementioned light-emitting element (LEL) may be provided for each pixel (PX). For example, a first pixel may include a first light-emitting element, a second pixel (PX) may include a second light-emitting element, and a third pixel may include a third light-emitting element. The first light-emitting element, the second light-emitting element, and the third light-emitting element may provide light of different colors. For example, the first light-emitting element may emit light of a first color, the second light-emitting element may emit light of a second color, and the third light-emitting element may emit light of a third color.

[0112] For example, the organic material layer of the first light-emitting layer of the first light-emitting region that emits light of a first color may be a phosphorescent material comprising a host material including CBP (carbazole biphenyl) or mCP (1,3-bis(carbazol-9-yl)) and a dopant including one or more selected from PIQIr(acac) (bis(1-phenylisoquinoline)acetylacetonate iridium), PQIr(acac) (bis(1-phenylquinoline)acetylacetonate iridium), PQIr (tris(1-phenylquinoline)iridium), and PtOEP (octaethylporphyrin platinum). Alternatively, the organic material layer of the first light-emitting layer of the first light-emitting region may be a fluorescent material including PBD:Eu(DBM)3 (Phen) or Perylene, but is not limited thereto.

[0113] The organic material layer of the second light-emitting layer in the second light-emitting region that emits light of a second color may be a phosphorescent material comprising a host material including CBP or mCP and a dopant material including Ir(ppy)3(fac tris(2-phenylpyridine)iridium). Alternatively, the organic material layer of the second light-emitting layer in the second light-emitting region that emits light of a second color may be a fluorescent material including Alq3(tris(8-hydroxyquinolino)aluminum), but is not limited thereto.

[0114] The organic material layer of the light-emitting layer of the third light-emitting region that emits light of a third color comprises a host material including CBP or mCP, and may be a phosphorescent material including a dopant material including (4,6-F2ppy)2Irpic or L2BD111, but is not limited thereto.

[0115] A common electrode (CM) may be disposed on the first, second, and third light-emitting layers (e.g., EL). The common electrode (CM) may be disposed to cover the first, second, and third light-emitting layers. The common electrode (CM) may be a common layer disposed in common to the first to third light-emitting layers. A capping layer may be formed on the common electrode (CM).

[0116] In the top light-emitting structure, the common electrode (CM) can be formed from a transparent conductive material (TCO, Transparent Conductive Material) such as ITO or IZO that can transmit light, or a semi-transmissive conductive material such as magnesium (Mg), silver (Ag), or an alloy of magnesium (Mg) and silver (Ag). When the common electrode (CM) is formed from a semi-transmissive conductive material, the light emission efficiency can be increased by the microcavity.

[0117] An encapsulation layer (ENC) may be formed on the light-emitting element layer (EMTL). The encapsulation layer (ENC) may include at least one inorganic film (TFE1, TFE3) to prevent oxygen or moisture from penetrating into the light-emitting element layer (EMTL). Additionally, the encapsulation layer (ENC) may include at least one organic film to protect the light-emitting element layer (EMTL) from foreign substances such as dust. For example, the encapsulation layer (ENC) may include a first encapsulation inorganic film (TFE1), an encapsulation organic film (TFE2), and a second encapsulation inorganic film (TFE3).

[0118] A first encapsulating inorganic film (TFE1) may be disposed on a common electrode (CM), an encapsulating organic film (TFE2) may be disposed on the first encapsulating inorganic film (TFE1), and a second encapsulating inorganic film (TFE3) may be disposed on the encapsulating organic film (TFE2). The first encapsulating inorganic film (TFE1) and the second encapsulating inorganic film (TFE3) may be formed as a multilayer film in which one or more inorganic films selected from a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, and an aluminum oxide layer are alternately stacked. The encapsulating organic film (TFE2) may be an organic film such as an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0119] FIG. 5 is a plan view of a display device (10) according to one embodiment. FIG. 6 is an enlarged view of the A1 region of FIG. 5. For example, FIG. 5 may be a plan view of a plurality of pixel electrodes (PE) and a plurality of light-emitting regions (EA) arranged in the display region of FIG. 1.

[0120] As illustrated in FIG. 5, light-emitting regions (EA) may overlap with pixel electrodes (PE). As previously mentioned, the light-emitting regions (EA) may be regions defined by a pixel defining layer (PDL). For example, the pixel defining layer (PDL) may have a plurality of openings (OP) penetrating the pixel defining layer (PDL) in a third direction (DR3), and the plurality of openings (OP) may correspond to light-emitting regions (EA) that expose a plurality of pixel electrodes (PE). The pixel defining layer (PDL) of FIG. 5 may be a pixel defining layer having a black color. For example, the pixel defining layer (PDL) of FIG. 5 may include carbon.

[0121] A pixel electrode (PE) and a light-emitting region (EA) that overlap each other may be included in a pixel (PX). For example, a pixel (PX) may include a pixel electrode (PE) and a light-emitting region (EA) that overlaps with the pixel electrode (PE).

[0122] As illustrated in FIG. 6, a plurality of pixels (PX1, PX2, PX3) that are adjacent to each other and provide different colored lights can form a unit pixel (UPX) for representing a unit image. For example, a first pixel (PX1) including a first pixel electrode (PE1) and a first light-emitting region (EA1) that overlap each other, a second pixel (PX2) including a second pixel electrode (PE2) and a second light-emitting region (EA2) that overlap each other, and a third pixel (PX3) including a third pixel electrode (PE3) and a third light-emitting region (EA3) that overlap each other can be arranged adjacently along one direction (e.g., a fifth direction (DR5)), and such first to third pixels (PX1, PX2, PX3) can form a unit pixel (UPX). Here, the first pixel (PX1) can provide light of a first color (e.g., light in the red wavelength band), the second pixel (PX2) can provide light of a second color (e.g., light in the green wavelength band), and the third pixel (PX3) can provide light of a third color (e.g., light in the blue wavelength band).

[0123] Pixels (PX1, PX2, PX3) included in a unit pixel (UPX) may include pixel electrodes (PE1, PE2, PE3) of different sizes. For example, as shown in FIG. 6, the first to third pixel electrodes (PE1, PE2, PE3) of the first to third pixels (PX1, PX2, PX3) included in the unit pixel (UPX) may have different sizes. For example, the area of ​​the first pixel electrode (PE1) may be larger than the area of ​​the second pixel electrode (PE2) and smaller than the area of ​​the third pixel electrode (PE3).

[0124] Each of the plurality of pixel electrodes (PE1, PE2, PE3) may have a polygonal shape. For example, each of the plurality of pixel electrodes (PE1, PE2, PE3) may have a rectangular shape.

[0125] Some of the pixel electrodes among the plurality of pixel electrodes (PE1, PE2, PE3) may include two sub-pixel electrodes connected to each other. For example, as shown in FIG. 6, the third pixel electrode (PE3) may include a first sub-pixel electrode (SPE1) and a second sub-pixel electrode (SPE2), one side of which is connected to each other and the other side of which is separated by a gap (G; or slit). The sides facing each other between the sub-pixel electrodes (PE) may be separated by the gap (G; or slit). Through the gap (G), outgas caused by the organic material of the first planarization layer (VA1) and the second planarization layer (VA2) can be smoothly discharged to the outside.

[0126] Each corner of the plurality of pixel electrodes (PE1, PE2, PE3) may have a shape that is cut diagonally. For example, each of the pixel electrodes (PE1, PE2, PE3) may have an octagonal shape. However, this is not limited thereto, and the shape of each of the plurality of pixel electrodes (PE1, PE2, PE3) can be varied in various ways.

[0127] A plurality of pixel electrodes (PE1, PE2, PE3) may be extended along a diagonal direction. For example, when a first side (S1) of a display panel (100) is extended along a second direction (DR2) and a third side (S3) of the display panel (100) is extended along a first direction (DR1), some of the pixel electrodes (e.g., a first pixel electrode (PE1)) among the plurality of pixel electrodes (PE1, PE2, PE3) may be extended along a fourth direction (DR4) between the first direction (DR1) and the second direction (DR2), and other pixel electrodes among the plurality of pixel electrodes (PE1, PE2, PE3) may be extended along a fifth direction (DR5) between the reverse direction of the first direction (DR1) (hereinafter, the first reverse direction) and the second direction (DR2). The angle between the first direction (DR1) and the fourth direction (DR4) may be 45 degrees, the angle between the second direction (DR2) and the fifth direction (DR5) may be 45 degrees, and the angle between the fourth direction (DR4) and the fifth direction (DR5) may be 90 degrees. However, the angle between the aforementioned directions is not limited to 45 degrees or 90 degrees and can be varied.

[0128] A pixel electrode (PE) extended along the fourth direction (DR4) may have a side longer in the fourth direction (DR4) than in the fifth direction (DR5). For example, when a pixel electrode extended along the fourth direction (DR4) (e.g., a first pixel electrode (PE1)) is defined as a first type pixel electrode, the side of the first type pixel electrode parallel to the fourth direction (DR4) may have a longer length than the side parallel to the fifth direction (DR5).

[0129] A pixel electrode extended along the fifth direction (DR5) may have a side longer in the fifth direction (DR5) than in the fourth direction (DR4). For example, when a pixel electrode extended along the fifth direction (DR5) is defined as a second-type pixel electrode, the side of the second-type pixel electrode parallel to the fifth direction (DR5) may have a longer length than the side parallel to the fourth direction (DR4).

[0130] Each pixel electrode (PE1, PE2, PE3) can be connected to an upper pixel connecting electrode (PCEb) through a seventh contact hole (CT7). For example, the first pixel electrode (PE1) is connected to the upper pixel connecting electrode (PCEb) through the seventh contact hole (CT7), the second pixel electrode (PE2) is connected to another upper pixel connecting electrode (PCEb) through another seventh contact hole (CT7), and the third pixel electrode (PE3) can be connected to another upper pixel connecting electrode (PCEb) through yet another seventh contact hole (CT7).

[0131] Each of the plurality of light-emitting regions (EA1, EA2, EA3) may have a polygonal shape. For example, each of the plurality of light-emitting regions (EA1, EA2, EA3) may have a rectangular shape. In this case, each corner of the plurality of light-emitting regions (EA1, EA2, EA3) may have a curved shape (or a rounded shape).

[0132] Some of the light-emitting regions (EA1, EA2, EA3) may include two separate sub-light-emitting regions. For example, as shown in FIG. 6, the third light-emitting region (EA3) may include a first sub-light-emitting region (SEA1) that overlaps with the aforementioned first sub-pixel electrode (SPE1) and a second sub-light-emitting region (SEA2) that overlaps with the aforementioned second sub-pixel electrode (SPE2). Multiple sub-light-emitting regions (EA) that overlap with a single pixel electrode may provide light of the same color. For example, the first sub-light-emitting region (SEA1) that overlaps with the first sub-pixel electrode (SPE1) of the third pixel electrode (PE3) and the second sub-light-emitting region (SEA2) that overlaps with the second sub-pixel electrode (SPE2) of the third pixel electrode (PE3) may provide light of the same color.

[0133] A plurality of light-emitting regions (EA1, EA2, EA3) may be extended along a diagonal direction. For example, some of the light-emitting regions (EA1, EA2, EA3) may be extended along a fourth direction (DR4), and some of the light-emitting regions (EA) may be extended along a fifth direction (DR5). In other words, a light-emitting region (e.g., EA1) that overlaps with a pixel electrode (e.g., a first type pixel electrode) extended along the fourth direction (DR4) is extended along the fourth direction (DR4), and a light-emitting region that overlaps with a pixel electrode (e.g., a second type pixel electrode) extended along the fifth direction (DR5) may be extended along the fifth direction (DR5).

[0134] A light-emitting region (e.g., EA2) extended along the fourth direction (DR4) may have a side longer in the fourth direction (DR4) than in the fifth direction (DR5). For example, when a light-emitting region (EA) extended along the fourth direction (DR4) is defined as a first type light-emitting region, the side of the first type light-emitting region parallel to the fourth direction (DR4) may have a longer length than the side parallel to the fifth direction (DR5).

[0135] A light-emitting region extended along the fifth direction (DR5) may have a side longer in the fifth direction (DR5) than in the fourth direction (DR4). For example, when a light-emitting region extended along the fifth direction (DR5) is defined as a second type light-emitting region, the side of the second type light-emitting region parallel to the fifth direction (DR5) may have a longer length than the side parallel to the fourth direction (DR4).

[0136] As described above, the edges of the light-emitting region (EA) may each have a curved shape, and in this case, any one edge among the entire edges of the light-emitting region (EA) may have a different radius of curvature from the other remaining edges. For example, among the entire edges of the light-emitting region (EA), the edge closest to the first side (S1) of the display panel (100) may have the largest radius of curvature. Specifically, among the entire edges of the light-emitting region (EA), the edge closest to the first side (S1) of the display panel (100) may have a larger radius of curvature than the other remaining edges. In other words, among the entire edges of the light-emitting region (EA), the edge closest to the first side (S1) of the display panel (100) may have a smaller radius of curvature than the other remaining edges.

[0137] Alternatively, among all the edges of the light-emitting area (EA), the edge having a convex shape toward the first side (S1) of the display panel (100) may have the largest radius of curvature. Specifically, among all the edges of the light-emitting area (EA), the edge having a convex shape toward the first side (S1) of the display panel (100) may have a larger radius of curvature than the other remaining edges. In other words, among all the edges of the light-emitting area (EA), the edge having a convex shape toward the first side (S1) of the display panel (100) may have a smaller curvature than the other remaining edges.

[0138] FIG. 7 is an enlarged view of a light-emitting region (EA) according to one embodiment. For example, the light-emitting region (EA) of FIG. 7 may be an enlarged view of the first light-emitting region (EA1) of FIG. 6 described above. FIG. 8 is a drawing for explaining the shape and radius of curvature of each corner of the light-emitting region (EA) of FIG. 7.

[0139] As illustrated in FIG. 7, the first light-emitting region (EA1) may include a first side (SS1), a second side (SS2), a third side (SS3), a fourth side (SS4), a first edge (CR1), a second edge (CR2), a third edge (CR3), and a fourth edge (CR4) connected to each other.

[0140] The first side (SS1), second side (SS2), third side (SS3), fourth side (SS4), first edge (CR1), second edge (CR2), third edge (CR3), and fourth edge (CR4) of the first light-emitting region (EA1) may be the inner wall of the opening (OP) defining the first light-emitting region (EA1). For example, the inner wall of the opening (OP) may include the first side (SS1), second side (SS2), third side (SS3), fourth side (SS4), first edge (CR1), second edge (CR2), third edge (CR3), and fourth edge (CR4).

[0141] The first side (S11), second side (S22), third side (S33), and fourth side (S44) of the first light-emitting region (EA1) may each have a straight line shape from a planar perspective.

[0142] At least two of the first side (S11), second side (S22), third side (S33) and fourth side (S44) of the first light-emitting region (EA1) may have different sizes (e.g., lengths). For example, the first side (S11) and the second side (S22) may each have a longer length than the third side (S33; or the fourth side (S44)).

[0143] The first side (S11), second side (S22), third side (S33), and fourth side (S44) of the first light-emitting region (EA1) can each be extended along a diagonal direction. For example, the first side (S11) and the second side (S22) can each be extended along the fourth direction (DR4), and the third side (S33) and the fourth side (S44) can each be extended along the fifth direction (DR5).

[0144] The corner between two adjacent sides of the first light-emitting region (EA1) may have a curved (or rounded) shape. For example, the first corner (CR1) between adjacent first side (S11) and third side (S33) may have a curved (or rounded) shape, the second corner (CR2) between adjacent second side (S22) and fourth side (S44) may have a curved (or rounded) shape, the third corner (CR3) between adjacent second side (S22) and third side (S33) may have a curved (or rounded) shape, and the fourth corner (CR4) between adjacent first side (S11) and fourth side (S44) may have a curved (or rounded) shape. At this time, as illustrated in FIG. 8, the first edge (CR1) of the first light-emitting region (EA1) has a curved shape arranged along the circumference of a virtual first circle (CC1) placed within the first light-emitting region (EA1) in proximity to the first edge (CR1), the second edge (CR2) of the first light-emitting region (EA1) has a curved shape arranged along the circumference of a virtual second circle (CC2) placed within the first light-emitting region (EA1) in proximity to the second edge (CR2), the third edge (CR3) of the first light-emitting region (EA1) has a curved shape arranged along the circumference of a virtual third circle (CC3) placed within the first light-emitting region (EA1) in proximity to the third edge (CR3), and the fourth edge (CR4) of the first light-emitting region (EA1) has a virtual fourth circle placed within the first light-emitting region (EA1) in proximity to the fourth edge (CR4). It can have a curved shape arranged along the circumference of the circle (CC4).

[0145] The edges (CR1, CR2, CR3, CR4) of the first light-emitting region (EA1) may have a curved shape that is convex toward different directions. For example, as shown in FIG. 7, the first edge (CR1) of the first light-emitting region (EA1) may have a curved shape that is convex toward the first reverse direction, the second edge (CR2) of the first light-emitting region (EA1) may have a curved shape that is convex toward the first direction (DR1), the third edge (CR3) of the first light-emitting region (EA1) may have a curved shape that is convex toward the reverse direction of the second direction (DR2) (hereinafter, the second reverse direction), and the fourth edge (CR4) of the first light-emitting region (EA1) may have a curved shape that is convex toward the second direction (DR2). Accordingly, the edges (CR1, CR2, CR3, CR4) of the light-emitting region (EA) may have a convex curve shape toward the different sides (S1, S2, S3, S4) of the display panel (100). For example, the first edge (CR1) of the first light-emitting area (EA1) may have a convex curve shape toward the first side (S1) of the display panel (100) along the first reverse direction, the second edge (CR2) of the first light-emitting area (EA1) may have a convex curve shape toward the second side (S2) of the display panel (100) along the first direction (DR1), the third edge (CR3) of the first light-emitting area (EA1) may have a convex curve shape toward the third side (S3) of the display panel (100) along the second reverse direction, and the fourth edge (CR4) of the first light-emitting area (EA1) may have a convex curve shape toward the fourth side (S4) of the display panel (100) along the second direction (DR2).

[0146] As illustrated in FIG. 7, among all the edges (CR1, CR2, CR3, CR4) of the first light-emitting region (EA), the edge (CR1) closest to the first side (S1) of the display panel (100) may have the largest radius of curvature. In other words, among all the edges (CR1, CR2, CR3, CR4) of the first light-emitting region (EA1), the first edge (CR1) closest to the first side (S1) of the display panel (100) may have a larger radius of curvature than the other remaining edges (CR2, CR3, CR4). For example, as illustrated in FIGS. 7 and 8, among the first to fourth edges (CR1, CR2, CR3, CR4), the first edge (CR1) having a shape convex toward the first side (S1) of the display panel (100) is positioned closest to the first side (S1) of the display panel (100), and the first edge (CR1) may have a larger radius of curvature (R1) than the other edges (CR2, CR3, CR4). For example, the radius of curvature (R1) of the first edge (CR1) may be larger than the radius of curvature (R2) of the second edge (CR2). In other words, a first edge (CR1) placed along the circumference of the first circle (CC1), which has the largest radius of curvature (R1) among the first to fourth circles (CC1, CC2, CC3, CC4), may have a larger radius of curvature (R1) than a second edge (CR2) placed along the circumference of the second circle (CC2). The radius of curvature (R2) of the second edge (CR2), the radius of curvature (R3) of the third edge (CR3), and the radius of curvature (R4) of the fourth edge (CR4) may all be the same.For example, the second circle (CC2), the third circle (CC3), and the fourth circle (CC4) may have the same radii of curvature (R2, R3, R4), and the second edge (CR2) placed along the perimeter of the second circle (CC2), the third edge (CR3) placed along the perimeter of the third circle (CC3), and the fourth edge (CR4) placed along the perimeter of the fourth circle (CC4) may each have the same radii of curvature (R2, R3, R4). However, this is not limited thereto, and under the condition that each of the radii of curvature (R2, R3, R4) of the second edge (CR2), the third edge (CR3), and the fourth edge (CR4) is smaller than the radius of curvature (R1) of the first edge (CR1), at least two of the second edge (CR2), the third edge (CR3), and the fourth edge (CR4) may have different radii of curvature.

[0147] According to one embodiment, the radius of curvature of each of the second corner (CR2), the third corner (CR3), and the fourth corner (CR4) may be smaller than the radius of curvature of the first corner (CR1). In this case, the area of ​​each light-emitting region (EA1, EA2, EA3) may be increased, that is to say, the aperture ratio of the display device (10) may be improved. The higher the aperture ratio of the display device (10), the more light can be generated with the same power consumption in a display area (DA) of the same area. Therefore, the higher the aperture ratio of the display device (10), the lower the power consumption of the display device (10), and accordingly, the lifespan of the display device (10) may be improved.

[0148] Light incident on each side (SS1, SS2, SS3, SS4) and each corner (CR1, CR2, CR3, CR4) of the first light-emitting area (EA1) of the display panel (100) can be reflected and scattered. Here, since each corner (CR1, CR2, CR3, CR4) of the first light-emitting area (EA1) has a curved shape, the amount of light reflected and scattered from each corner (CR1, CR2, CR3, CR4) of the first light-emitting area (EA1) may be smaller than the amount of light reflected and scattered from each side (SS1, SS2, SS3, SS4) of the first light-emitting area (EA1). Additionally, the first edge (CR1) of the first light-emitting region (EA1) has a larger radius of curvature (R1) than the other edges (CR2, CR3, CR4) of the first light-emitting region (EA1). Thus, the first light-emitting region (EA1) of this structure can provide a relatively smaller amount of scattered light compared to a light-emitting region (hereinafter, a light-emitting region to be compared) having edges with the same radius of curvature. In other words, the amount of scattered light reflected from the first light-emitting region (EA1) having a first edge with a relatively larger radius of curvature (e.g., a first edge having a radius of curvature larger than the radius of curvature of the other edges) can be smaller than the amount of scattered light reflected from the light-emitting region to be compared. At this time, since each first corner (CR1) of the light-emitting regions (EA) is positioned closer to the first side (S1) of the display panel (100) than the other corners (CR2, CR3, CR4), the amount of scattered light reflected from the light-emitting regions (EA) and directed toward the first side (S1) of the display panel (100) can be reduced.

[0149] FIG. 9 is a drawing showing a part of a vehicle (900) including a display device (10) according to one embodiment, and FIG. 10 is an enlarged view of the part of FIG. 9.

[0150] As illustrated in FIG. 9, a display device (10) may be placed in a vehicle (900). For example, a plurality of display devices (10_C1, 10_C2, 10_C3, 10_C4) may be placed in the vehicle (900). At this time, the first display device (10_C1) may be placed in the center of the vehicle (900) (e.g., the center between the driver's seat (910) and the passenger seat (920) of the vehicle (900)), the second display device (10_C2) may be placed on the first display device (10_C1) in the center of the vehicle (900), the third display device (10_C3) may be placed to the right of the driver's seat (910) of the vehicle (900), and the fourth display device (10_C4) may be placed to the left of the driver's seat (910) of the vehicle (900). The driver's seat (910) of the vehicle (900) may face the steering wheel (930). Here, the third display device (10_C3) may be positioned to the right of the steering wheel (930), and the fourth display device (10_C4) may be positioned to the left of the steering wheel (930).

[0151] A first edge (S1; e.g., a first edge (S1) of the display panel (100) of the first display device (10_C1)) can be positioned close to the driver's seat (910). Accordingly, a first edge (CR1) having the largest radius of curvature (R1) among all edges (CR1, CR2, CR3, CR4) of the light-emitting area (EA) of the first display device (10_C1) can be positioned close to the driver's seat (910). In other words, each first edge (CR1) of all light-emitting areas (EA) of the first display device (10_C1; e.g., a display panel (100) of the first display device (10_C1) can be positioned close to the driver's seat (910).

[0152] A first edge (S1; e.g., a first edge (S1) of the display panel (100) of the second display device (10_C2)) can be positioned close to the driver's seat (910). Accordingly, a first edge (CR1) having the largest radius of curvature (R1) among all edges (CR1, CR2, CR3, CR4) of the light-emitting area (EA) of the second display device (10_C2) can be positioned close to the driver's seat (910). In other words, each first edge (CR1) of all light-emitting areas (EA) of the second display device (10_C2; e.g., a display panel (100) of the second display device (10_C2) can be positioned close to the driver's seat (910).

[0153] A first edge (S1; e.g., a first edge (S1) of the display panel (100) of the third display device (10_C3)) can be positioned close to the driver's seat (910). Accordingly, a first edge (CR1) having the largest radius of curvature (R1) among all edges (CR1, CR2, CR3, CR4) of the light-emitting area (EA) of the third display device (10_C3) can be positioned close to the driver's seat (910). In other words, each first edge (CR1) of all light-emitting areas (EA) of the third display device (10_C3; e.g., a display panel (100) of the third display device (10_C3) can be positioned close to the driver's seat (910).

[0154] The first edge (S1; e.g., the first edge (S1) of the display panel (100) of the fourth display device (10_C4)) can be positioned close to the driver's seat (910). Accordingly, the first edge (CR1) having the largest radius of curvature among all the edges (CR1, CR2, CR3, CR4) of the light-emitting area (EA) of the fourth display device (10_C4) can be positioned close to the driver's seat (910). In other words, each first edge (CR1) of all the light-emitting areas (EA) of the fourth display device (10_C4; e.g., the display panel (100) of the fourth display device (10_C4) can be positioned close to the driver's seat (910). Here, the first side (S1) of the fourth display device (10_C4) may be positioned to face the first side (S1) of another display device (10). For example, the first side (S1) of the fourth display device (10_C4) may face the first side (S1) of the third display device (10_C3).

[0155] As illustrated in FIG. 10, light (111) from the outside can be incident on the first display device (10_C1). The light (111) incident on each side (SS1, SS2, SS3, SS4) and each corner (CR1, CR2, CR3, CR4) of the light-emitting region (EA) of the first display device (10_C1) can be reflected. Here, since each corner (CR1, CR2, CR3, CR4) of the light-emitting region (EA) has a curved shape, the amount of light reflected and scattered from each corner (CR1, CR2, CR3, CR4) of the light-emitting region (EA) may be smaller than the amount of light reflected and scattered from each side (SS1, SS2, SS3, SS4) of the light-emitting region (EA). Additionally, the first corner (CR1) of the light-emitting region (EA) has a larger radius of curvature than the other corners (CR2, CR3, CR4) of the light-emitting region (EA). Thus, the first light-emitting region (EA1) of this structure can provide a relatively smaller amount of scattered light compared to a light-emitting region (hereinafter, a light-emitting region of comparison) having corners of the same radius of curvature. In other words, the amount of scattered light reflected from the first light-emitting region (EA1) having a first corner with a relatively larger radius of curvature (e.g., a first corner having a radius of curvature larger than the radius of curvature of the other corners) can be smaller than the amount of scattered light reflected from the light-emitting region of comparison. At this time, since each first corner (CR1) of the light-emitting regions (EA) is positioned closer to the driver's seat (910) than the other corners (CR2, CR3, CR4), the amount of scattered light reflected from the light-emitting regions (EA) and directed toward the driver's seat (910) can be reduced. Accordingly, the amount of scattered light (111) directed toward the driver's seat (910) among the scattered light reflected from the first display device (10_C1) can be reduced. Therefore, glare for the driver located in the driver's seat (910) can be minimized.

[0156] Likewise, the amount of scattered light reflected from the second display device (10_C2), the third display device (10_C3), and the fourth display device (10_C4) toward the driver's seat (910) can be minimized.

[0157] FIG. 11 is an enlarged view of a display device (10) according to one embodiment, and FIG. 12 is an enlarged view of a light-emitting region (EA) according to one embodiment. For example, the light-emitting region (EA) of FIG. 12 may be an enlarged view of the first light-emitting region (EA1) of FIG. 11 described above. FIG. 13 is a drawing for explaining the shape and radius of curvature of each corner of the first light-emitting region (EA1) of FIG. 12.

[0158] The display device (10) of FIGS. 11 to 13 differs from the display device (10) of FIGS. 6 to 8 described above in that each first corner (CR1) of each light-emitting area (EA1, EA2, EA3) includes a plurality of sub-corners, and this difference is explained in detail as follows.

[0159] As illustrated in FIGS. 11 to 13, the first edge (CR1) of the first light-emitting region (EA1) may include a first sub-edge (SCR1) and a second sub-edge (SCR2). However, it is not limited thereto, and the first edge (CR1) of the first light-emitting region (EA1) may include more than two sub-edges.

[0160] The sub-edges (SCR1, SCR2) of the first light-emitting area (EA1) may have a convex curve shape toward the same side of the display panel (100). For example, the first sub-edge (SCR1) of the light-emitting area (EA) may have a convex curve shape toward the first side (S1) of the display panel (100), and the second sub-edge (SCR2) of the light-emitting area (EA) may have a convex curve shape toward the first side (S1) of the display panel (100).

[0161] The second sub-edge (SCR2) may be positioned adjacent to the first sub-edge (SCR1). For example, the second sub-edge (SCR2) and the first sub-edge (SCR1) may be positioned adjacent to each other along the second direction (DR2). The second sub-edge (SCR2) may be connected to the first sub-edge (SCR1).

[0162] The first sub-edge (SCR1) may have a larger radius of curvature than the other edges, such as the second edge (CR2), the third edge (CR3), and the fourth edge (CR4).

[0163] The second sub-edge (SCR2) may have a larger radius of curvature than the other edges, such as the second edge (CR2), the third edge (CR3), and the fourth edge (CR4).

[0164] The first sub-edge (SCR1) and the second sub-edge (SCR2) may have the same radius of curvature. However, they are not limited thereto, and under the condition that the radius of curvature of the first sub-edge (SCR1) and the radius of curvature of the second sub-edge (SCR2) are greater than the radii of curvature of the second edge (CR2), third edge (CR3), and fourth edge (CR4) described above, the radius of curvature of the first sub-edge (SCR1) and the radius of curvature of the second sub-edge (SCR2) may be different from each other. For example, the radius of curvature of the first sub-edge (SCR1) may be smaller or larger than the radius of curvature of the second sub-edge (SCR2).

[0165] As illustrated in FIG. 13, the first sub-edge (SCR1) of the first light-emitting region (EA1) has a curved shape arranged along the circumference of a virtual first sub-circle (SCC1) arranged within the first light-emitting region (EA1) in proximity to the first sub-edge (SCR1), and the second sub-edge (SCR2) of the first light-emitting region (EA1) may have a curved shape arranged along the circumference of a virtual second sub-circle (SCC2) arranged within the first light-emitting region (EA1) in proximity to the second sub-edge (SCR2).

[0166] Likewise, the first edge (CR1) of the second light-emitting region (EA2) may include a first sub-edge (SCR1) and a second sub-edge (SCR2). However, it is not limited thereto, and the first edge (CR1) of the second light-emitting region (EA2) may include more than two sub-edges.

[0167] Likewise, the first edge (CR1) of the third light-emitting region (EA3) may include a first sub-edge (SCR1) and a second sub-edge (SCR2). However, it is not limited thereto, and the first edge (CR1) of the third light-emitting region (EA3) may include more than two sub-edges.

[0168] FIG. 14 is an enlarged view of a light-emitting area (EA) of a display device (10) according to one embodiment, and FIG. 15 is a drawing for explaining the shape and radius of curvature of each corner of the light-emitting area (EA) of FIG. 14.

[0169] The display device (10) of FIGS. 14 and FIGS. 15 has a difference from the display device (10) of FIGS. 6 to FIGS. 8 described above in terms of the shape of the pixel electrode (PE) and the light-emitting region (EA). This difference is explained in detail as follows.

[0170] As shown in FIGS. 14 and 15, from a planar perspective, the first pixel electrode (PE1) and the first light-emitting region (EA1) may each have a hexagonal shape.

[0171] As illustrated in FIG. 14, the first light-emitting region (EA1) may include a first side (S1), a second side (S2), a third side (S3), a fourth side (S4), a fifth side (S5), a sixth side (S6), a first edge (CR1), a second edge (CR2), a third edge (CR3), a fourth edge (CR4), a fifth edge (CR5), and a sixth edge (CR6) connected to each other.

[0172] The first side (S11), second side (S22), third side (S33), fourth side (S44), fifth side (S55), sixth side (S66), first edge (CR1), second edge (CR2), third edge (CR3), fourth edge (CR4), fifth edge (CR5), and sixth edge (CR6) of the first light-emitting region (EA1) may be the inner wall of the opening (OP) defining the first light-emitting region (EA1). For example, the inner wall of the opening (OP) may include the first side (S11), second side (S22), third side (S33), fourth side (S44), fifth side (S55), sixth side (S66), first edge (CR1), second edge (CR2), third edge (CR3), fourth edge (CR4), fifth edge (CR5), and sixth edge (CR6).

[0173] The first side (S11), second side (S22), third side (S33), fourth side (S44), fifth side (S55), and sixth side (S66) of the first light-emitting region (EA1) may each have a straight line shape from a planar perspective.

[0174] The first side (S11), second side (S22), third side (S33), fourth side (S44), fifth side (S55), and sixth side (S66) of the first light-emitting region (EA1) may have the same size (e.g., length). However, this is not limited thereto, and for example, at least two sides among the first side (S11), second side (S22), third side (S33), fourth side (S44), fifth side (S55), and sixth side (S66) of the first light-emitting region (EA1) may have different sizes (e.g., length).

[0175] The first side (S11), second side (S22), third side (S33), and fourth side (S44) of the first light-emitting region (EA1) can each be extended along a diagonal direction. For example, the first side (S11) and the second side (S22) can each be extended along the fifth direction (DR5), and the third side (S33) and the fourth side (S44) can each be extended along the fourth direction (DR4).

[0176] The fifth side (S55) and the sixth side (S66) of the first light-emitting region (EA1) may each extend along the horizontal direction. For example, the fifth side (S55) and the sixth side (S66) may each extend along the first direction (DR1).

[0177] The corner between two adjacent sides of the first light-emitting region (EA1) may have a curved (or round) shape. For example, the first edge (CR1) between the adjacent first side (S1) and the third side (S3) has a curved (or rounded) shape, the second edge (CR2) between the adjacent second side (S2) and the fourth side (S4) has a curved (or rounded) shape, the third edge (CR3) between the adjacent first side (S1) and the fifth side (S5) has a curved (or rounded) shape, the fourth edge (CR4) between the adjacent third side (S3) and the sixth side (S6) may have a curved (or rounded) shape, the fifth edge (CR5) between the adjacent fourth side (S4) and the fifth side (S5) may have a curved (or rounded) shape, and the sixth edge (CR6) between the adjacent second side (S2) and the sixth side (S6) may have a curved (or rounded) shape.At this time, as illustrated in FIG. 15, the first edge (CR1) of the first light-emitting region (EA1) has a curved shape arranged along the circumference of a virtual first circle (CC1) placed within the light-emitting region (EA) in proximity to the first edge (CR1), the second edge (CR2) of the first light-emitting region (EA1) has a curved shape arranged along the circumference of a virtual second circle (CC2) placed within the first light-emitting region (EA1) in proximity to the second edge (CR2), the third edge (CR3) of the first light-emitting region (EA1) has a curved shape arranged along the circumference of a virtual third circle (CC3) placed within the first light-emitting region (EA1) in proximity to the third edge (CR3), and the fourth edge (CR4) of the first light-emitting region (EA1) has a virtual fourth circle placed within the first light-emitting region (EA1) in proximity to the fourth edge (CR4). The first light-emitting region (EA1) has a curved shape arranged along the circumference of a circle (CC4), the fifth corner (CR5) of the first light-emitting region (EA1) has a curved shape arranged along the circumference of a virtual fifth circle (CC5) arranged within the first light-emitting region (EA1) in proximity to the fifth corner (CR5), and the sixth corner (CR6) of the first light-emitting region (EA1) can have a curved shape arranged along the circumference of a virtual sixth circle (CC6) arranged within the first light-emitting region (EA1) in proximity to the sixth corner (CR6).

[0178] The edges (CR1, CR2, CR3, CR4, CR5, CR6) of the first light-emitting region (EA1) may have a convex curve shape facing in different directions. For example, the first edge (CR1) of the first light-emitting region (EA1) may have a curve shape that is convex in the first reverse direction, the second edge (CR2) of the first light-emitting region (EA1) may have a curve shape that is convex in the first direction (DR1), the third edge (CR3) of the first light-emitting region (EA1) may have a curve shape that is convex in the reverse direction of the fourth direction (DR4) (hereinafter, fourth reverse direction), the fourth edge (CR4) of the first light-emitting region (EA1) may have a curve shape that is convex in the fifth direction (DR5), the fifth edge (CR5) of the first light-emitting region (EA1) may have a curve shape that is convex in the reverse direction of the fifth direction (DR5) (hereinafter, fifth reverse direction), and the sixth edge (CR6) of the first light-emitting region (EA1) may have a curve shape that is convex in the fourth direction (DR4). Here, the first edge (CR1) may have a convex curve shape toward the first side (S1) of the display panel (100) along the first reverse direction, and the second edge (CR2) may have a convex curve shape toward the second side (S2) of the display panel (100) along the first direction (DR1).

[0179] As illustrated in FIG. 14, among all the edges (CR1, CR2, CR3, CR4, CR5, CR6) of the first light-emitting region (EA1), the edge closest to the first side (S1) of the display panel (100) may have the largest radius of curvature. In other words, among all the edges (CR1, CR2, CR3, CR4, CR5, CR6) of the first light-emitting region (EA1), the first edge (CR1) closest to the first side (S1) of the display panel (100) may have a larger radius of curvature (R1) than the other remaining edges (CR2, CR3, CR4, CR5, CR6). For example, as illustrated in FIG. 15, among the first to sixth edges (CR1, CR2, CR3, CR4, CR5, CR6), the first edge (CR1) having a shape convex toward the first side (S1) of the display panel (100) is positioned closest to the first side (S1) of the display panel (100), and the first edge (CR1) may have a larger radius of curvature (R1) than the other edges (CR2, CR3, CR4, CR5, CR6). For example, the radius of curvature (R1) of the first edge (CR1) may be larger than the radius of curvature (R2) of the second edge (CR2). In other words, a first edge (CR1) placed along the circumference of the first circle (CC1), which has the largest radius of curvature (R1) among the first to sixth circles (CC1, CC2, CC3, CC4, CC5, CC6), may have a larger radius of curvature (R1) than a second edge (CR2) placed along the circumference of the second circle (CC2). The radius of curvature (R2) of the second edge (CR2), the radius of curvature (R3) of the third edge (CR3), the radius of curvature (R4) of the fourth edge (CR4), the radius of curvature (R5) of the fifth edge (CR5), and the radius of curvature (R6) of the sixth edge (CR6) may all be the same.For example, the second circle (CC2), the third circle (CC3), the fourth circle (CC4), the fifth circle (CC5), and the sixth circle (CC6) may have the same radius of curvature, and the second edge (CR2) placed along the circumference of the second circle (CC2), the third edge (CR3) placed along the circumference of the third circle (CC3), the fourth edge (CR4) placed along the circumference of the fourth circle (CC4), the fifth edge (CR5) placed along the circumference of the fifth circle (CC5), and the sixth edge (CR6) placed along the circumference of the sixth circle (CC6) may each have the same radius of curvature. However, not limited thereto, under the condition that the radius of curvature of each of the second edge (CR2), third edge (CR3), fourth edge (CR4), fifth edge (CR5) and sixth edge (CR6) is smaller than the radius of curvature of the first edge (CR1), at least two of the second edge (CR2), third edge (CR3), fourth edge (CR4), fifth edge (CR5) and sixth edge (CR6) may have different radii of curvature.

[0180] Light incident on each side (SS1-SS6) and each corner (CR1-CR6) of the first light-emitting region (EA1) of the display panel (100) can be reflected and scattered. Here, since each corner (CR1-CR6) of the first light-emitting region (EA) has a curved shape, the amount of light reflected and scattered from each corner (CR1-CR6) of the light-emitting region (EA) may be smaller than the amount of light reflected and scattered from each side (SS1-SS6) of the first light-emitting region (EA1). Additionally, since the first corner (CR1) of the first light-emitting region (EA1) has a larger radius of curvature than the other corners (CR2-CR6) of the light-emitting region (EA), the first light-emitting region (EA1) with this structure can provide a relatively smaller amount of scattered light compared to a light-emitting region (hereinafter, a light-emitting region to be compared) having corners with the same radius of curvature. In other words, the amount of scattered light reflected from a first light-emitting region (EA1) having a first edge with a relatively larger curvature (e.g., a first edge having a radius of curvature larger than the radius of curvature of other edges) may be smaller than the amount of scattered light reflected from a light-emitting region of comparison. In this case, since each first edge (CR1) of the first light-emitting regions (EA1) is positioned closer to the first side (S1) of the display panel (100) than the other edges (CR2-CR6), the amount of scattered light reflected from the first light-emitting region (EA1) and directed toward the first side (S1) of the display panel (100) may be reduced.

[0181] The display device (10) of FIGS. 14 and 15 can be applied to a vehicle (900) as illustrated in FIGS. 9 and 10 above. In this case, the first corner (CR1) of the first light-emitting area (EA1) of the display device (10) of FIGS. 14 and 15 can be positioned close to the first side (S1) of the display device (10); or the first side (S1) of the display panel (100) of the display device (10). Accordingly, the amount of scattered light from the display device (10) directed toward the driver's seat (910) is reduced, so that glare to the driver can be minimized.

[0182] FIG. 16 is an enlarged view of a display device (10) according to one embodiment, and FIG. 17 is an enlarged view of a light-emitting region (EA) according to one embodiment. For example, the light-emitting region (EA) of FIG. 17 may be an enlarged view of the first light-emitting region (EA1) of FIG. 16 described above. FIG. 18 is a drawing for explaining the shape and radius of curvature of each corner of the first light-emitting region (EA1) of FIG. 17.

[0183] The display device (10) of FIGS. 16 to 18 differs from the display device (10) of FIGS. 6 to 8 described above in that the first corner (CR1) and the second corner (CR2) of the first light-emitting region (EA1) each have a larger radius of curvature than the other corners (CR3, CR4). This difference is explained in detail as follows.

[0184] As illustrated in FIGS. 16 to 18, the respective radii of curvature (R1, R2) of the first edge (CR1) and the second edge (CR2) of the first light-emitting region (EA1) may be larger than the radii of curvature (R3, R4) of the third edge (CR3) and the fourth edge (CR4) of the first light-emitting region (EA1). For example, the radius of curvature (R1) of the first edge (CR1) may be larger than the radius of curvature (R3) of the third edge (CR3; or the fourth edge (CR4)), and the radius of curvature (R2) of the second edge (CR2) may be larger than the radius of curvature (R3) of the third edge (CR3; or the fourth edge (CR4)).

[0185] The radius of curvature (R2) of the second edge (CR2) may be the same as the radius of curvature (R1) of the first edge (CR1). However, it is not limited thereto, and the radius of curvature (R2) of the second edge (CR2) may be different from the radius of curvature (R1) of the first edge (CR1) under the condition that the radius of curvature (R2) of the second edge (CR2) is greater than the radius of curvature (R3) of the third edge (CR3; or fourth edge (CR4)). For example, under the condition that the radius of curvature (R2) of the second edge (CR2) is greater than the radius of curvature (R3) of the third edge (CR3; or fourth edge (CR4)), the radius of curvature (R2) of the second edge (CR2) may be greater or smaller than the radius of curvature (R1) of the first edge (CR1).

[0186] Since the first corner (CR1) and the second corner (CR2) of the first light-emitting region (EA1) have a larger radius of curvature than the other corners (CR3, CR4) of the first light-emitting region (EA1), the amount of scattered light reflected from the first corner (CR1) and the amount of scattered light reflected from the second corner (CR2) may be smaller than the amount of scattered light reflected from the other corners (CR3, CR4). At this time, since each first corner (CR1) of the first light-emitting region (EA) is positioned closer to the first side (S1) of the display panel (100) than the other corners (CR2, CR3, CR4), the amount of scattered light reflected from the light-emitting region (EA) and directed toward the first side (S1) of the display panel (100) may be reduced. Additionally, since each second corner (CR2) of the first light-emitting regions (EA1) is positioned closer to the second side (S2) of the display panel (100) than the other corners (CR1, CR3, CR4), the amount of scattered light reflected from the first light-emitting regions (EA1) and directed toward the second side (S2) of the display panel (100) can be reduced.

[0187] The radius of curvature (R1, R2) of the first edge (CR1) and the second edge (CR2) of the second light-emitting region (EA2) may be larger than the radius of curvature (R3, R4) of the third edge (CR3) and the fourth edge (CR4) of the second light-emitting region (EA2).

[0188] The radius of curvature (R1, R2) of the first corner (CR1) and the second corner (CR2) of the third light-emitting region (EA3) may be larger than the radius of curvature (R3, R4) of the third corner (CR3) and the fourth corner (CR4) of the third light-emitting region (EA3).

[0189] Additionally, as illustrated in FIG. 16, among the pattern layers disposed between the substrate (SUB) and the pixel electrode (PE of FIG. 4, or PE1, PE2, or PE3 of FIG. 16), the pattern layer closest to the pixel electrode (PE) (e.g., the eighth pattern layer (PTL8)) may extend along the convex direction of the first corner (CR1) of the light-emitting region (e.g., EA1). For example, the eighth pattern layer (PTL8) may be disposed closest to the pixel electrode (PE), and the eighth pattern layer (PTL8) may extend in a direction parallel to the convex direction (e.g., the first reverse direction) of the first corner (CR1) of the first light-emitting region (EA1). Here, the pixel defining layer (PDL) of FIG. 16 to 18 may include, for example, an organic material. For example, the pixel defining layer (PDL) of FIG. 16 to 18 may include polyimide.

[0190] The eighth pattern layer (PTL8) may be provided in plurality. The plurality of eighth pattern layers (PTL8) may include, for example, data lines (DL) and power lines (e.g., driving voltage line (VDL), first initialization voltage line (VIL1), second initialization voltage line (VIL2), common voltage line (VSL)), etc. Here, the plurality of data lines (DL) may include a first data line, a second data line, and a third data line, each connected to a first pixel (PX1), a second pixel (PX2), and a third pixel (PX3), respectively, which provide different colored lights. Here, the first data line, the second data line, and the third data line are not connected to each other.

[0191] A plurality of eighth pattern layers (PTL8) may each extend along the first direction (DR1). Additionally, a plurality of eighth pattern layers (PTL8) may be spaced apart from each other along the second direction (DR2). For example, a data line (DL), a driving voltage line (VDL), a first initialization voltage line (VIL1), a second initialization voltage line (VIL2), and a common voltage line (VSL) may each extend along the first direction (DR1). Additionally, a data line (DL), a driving voltage line (VDL), a first initialization voltage line (VIL1), a second initialization voltage line (VIL2), and a common voltage line (VSL) may be spaced apart from each other along the second direction (DR2).

[0192] As the eighth pattern layers (PTL8) are extended along the first direction (DR1) in this manner, scattered light reflected by the eighth pattern layers (PTL8) toward the first direction (DR1) and the first reverse direction can be minimized. For example, when the eighth pattern layers (PTL8) are extended in the first direction (DR1), the area of ​​the eighth pattern layers (PTL8) visible in the first direction (DR1) and the first reverse direction can be smaller than the area of ​​the eighth pattern layers (PTL8) visible in the first direction (DR1) and the first reverse direction when the eighth pattern layers (PTL8) are extended in the second direction (DR2). For example, when the eighth pattern layers (PTL8) are each extended in the first direction (DR1) and the components of the eighth pattern layers (PTL8) are spaced apart along the second direction (DR2), the area of ​​the eighth pattern layers (PTL8) visible in the first direction (DR1) and the first reverse direction may be reduced due to the gap between the components of the eighth pattern layers (PTL8) adjacent in the second direction (DR2). On the other hand, when the components of the eighth pattern layers (PTL8) are each extended in the second direction (DR2) and the components of the eighth pattern layers (PTL8) are spaced apart along the first direction (DR1), the gap between the eighth pattern layers (PTL8) is not visible in the first direction (DR1) and the first reverse direction, and instead, all sides of the eighth pattern layers (PTL8) along each extension direction of the eighth pattern layers (PTL8) can be seen in the first direction (DR1) and the first reverse direction. Therefore, when the eighth pattern layers (PTL8) are extended along the second direction (DR2), the amount of scattered light reflected in the first direction (DR1) and the first reverse direction can be increased.

[0193] The display device (10) of FIGS. 16 to 18 may be advantageous for reducing scattered light by a metal layer (e.g., the eighth pattern layer (PTL8)) placed immediately below the pixel definition layer (PDL), for example, when the pixel definition layer (PDL) is made of an organic material that does not contain carbon.

[0194] FIG. 19 is an enlarged view of a part of a vehicle (900) including the display device (10) of FIG. 16 to 18.

[0195] As illustrated in FIG. 19, the display device (10) can be placed in the vehicle (900). For example, the display device (10) can be placed in the center of the vehicle (900) (e.g., the center between the driver's seat (910) and the passenger seat (920) of the vehicle (900).

[0196] A first side (S1; for example, a first side (S1) of the display panel (100) of the display device (10)) may be positioned close to the driver's seat (910), and a second side (S2; for example, a second side (S2) of the display panel (100) of the display device (10)) may be positioned close to the passenger seat (920). Accordingly, a first corner (CR1) of a first light-emitting area (EA1) of the display device (10) may be positioned close to the driver's seat (910), and a second corner (CR2) of a first light-emitting area (EA1) of the display device (10) may be positioned close to the passenger seat (920). Additionally, the eighth pattern layer (PTL8) may be extended along a virtual line connecting the first side (S1) and the second side (S2) of the display device (10) (e.g., a virtual line extended along the first direction (DR1)). In other words, each of the components of the eighth pattern layer (PTL8) (e.g., a data line (DL), a driving voltage line (VDL), an upper pixel connection electrode (PCEb), a driving voltage line (VDL), a first initialization voltage line (VSL1), a second initialization voltage line (VSL2), and a common voltage line (VSL)) may be extended along the first direction (DR1). Accordingly, the amount of scattered light (222) directed toward the driver's seat (910) and the passenger seat (920) among the scattered light reflected from the display device (10) may be reduced. Therefore, glare for the driver located in the driver's seat (910) and the passenger located in the passenger seat (920) may be minimized.

[0197] The display device (10) of FIGS. 16 to 18 can be applied to a vehicle (900) as illustrated in FIGS. 9 and 10 above. In this case, the first corner (CR1) of the light-emitting area (EA) of the display device (10) of FIGS. 14 and 15 can be positioned close to the first side (S1) of the display device (10); or the first side (S1) of the display panel (100) of the display device (10). Accordingly, the amount of scattered light from the display device (10) directed toward the driver's seat (910) is reduced, thereby minimizing glare for the driver.

[0198] FIG. 20 is a plan view of a display device (10) according to one embodiment.

[0199] The display device (10) of FIG. 20 has a difference from the display device (10) of FIG. 7 described above regarding the position of the 7th contact hole (CT7), and this difference is explained in detail as follows.

[0200] As illustrated in FIG. 20, the seventh contact hole (CT7) can be positioned adjacent to the first corner (CR1) of the light-emitting region (EA). At this time, the seventh contact hole (CT7) can be positioned to overlap with the first pixel electrode (PE1). In other words, the seventh contact hole (CT7) can be positioned adjacent to the first corner (CR1) of the first light-emitting region (EA1) to overlap with the first pixel electrode (PE1).

[0201] As illustrated in FIG. 20, from a planar perspective, the seventh contact hole (CT7) can be positioned between the first corner (CR1) of the light-emitting region (EA) and the corner of the first pixel electrode (PE1) (e.g., the corner of the first pixel electrode (PE1) adjacent to the first corner (CR1).

[0202] Since the first corner (CR1) of the first light-emitting region (EA1) has a larger radius of curvature than the other corners (CR2-CR4) of the first light-emitting region (EA1), the overlap area between the pixel definition layer (PDL) and the first pixel electrode (PE1) around the first corner (CR1) may be larger than the overlap area between the pixel definition layer (PDL) and the first pixel electrode (PE1) around the other corners. Accordingly, the seventh contact hole (CT7) may be positioned to overlap with the first pixel electrode (PE1). In this case, the distance between adjacent pixel electrodes (PE1, PE2, PE3) can be designed to be closer, thereby improving the resolution of the display device (10).

[0203] Additionally, the aforementioned seventh contact hole (CT7) may be positioned adjacent to, for example, the first corner (CR1) of the first light-emitting region (EA1) shown in FIG. 12. In a planar view, the seventh contact hole (CT7) may be positioned between the first corner (CR1) of the first light-emitting region (EA1) and the corner of the first pixel electrode (PE1) (e.g., the corner of the first pixel electrode (PE1) adjacent to the first corner (CR1).

[0204] Additionally, the aforementioned seventh contact hole (CT7) may be positioned adjacent to the first corner (CR1) of the first light-emitting region (EA1) shown in FIG. 14, for example. In a planar view, the seventh contact hole (CT7) may be positioned between the first corner (CR1) of the first light-emitting region (EA1) and the corner of the first pixel electrode (PE1) (e.g., the corner of the first pixel electrode (PE1) adjacent to the first corner (CR1).

[0205] Additionally, the aforementioned seventh contact hole (CT7) may be positioned adjacent to the second corner (CR2) of the first light-emitting region (EA1) shown in FIG. 17, for example. In a planar view, the seventh contact hole (CT7) may be positioned between the second corner (CR2) of the first light-emitting region (EA1) and the corner of the first pixel electrode (PE1) (e.g., the corner of the first pixel electrode (PE1) adjacent to the second corner (CR2).

[0206] The display device (10) according to the embodiment can be applied to various electronic devices. An electronic device according to one embodiment includes the display device (10) described above and may further include a module or device having other additional functions in addition to the display device (10).

[0207] FIG. 21 is a block diagram of an electronic device according to one embodiment. Referring to FIG. 21, an electronic device (50) according to one embodiment may include a display module (11; e.g., a display device (10)), a processor (12), a memory (13), and a power module (14).

The power module (14) may include a power supply module, such as a power adapter or battery device, and a power conversion module that converts the power supplied by the power supply module to generate power necessary for the operation of the electronic device (50). The input module (14) can provide input information to the processor (12) and / or the display module (11). The non-image output module (15) can receive information other than images received from the processor (12), such as sound, haptics, light emission, etc., and provide this information to the user. The communication module (16) is a module responsible for the transmission and reception of information between the electronic device (50) and an external device, and may include a receiving unit and a transmitting unit.

[0209] At least one of each component of the electronic device (50) described above may be included in a display device according to the embodiments described above. Additionally, some of the individual modules functionally included in one module may be included in the display device, while others may be provided separately from the display device. For example, the display device may include a display module (11), and the processor (12), memory (13), and power module (14) may be provided in the form of other devices within the electronic device (50) that are not the display device.
