[0050] FIG. 2 is a plan view showing a display device according to one embodiment of the present specification. FIG. 3 is a cross-sectional view showing a portion cut along the line X1-X1' of FIG. 2.

[0051] FIG. 1 illustrates a state in which a display device (10) is unfolded without being bent, and FIG. 2 and FIG. 3 illustrate a state in which a display device (10) is bent in a sub-region (SBA). FIG. 1 illustrates a state in which a sub-region (SBA) is unfolded parallel to a main region (MA), and FIG. 2 and FIG. 3 illustrate a state in which a part of the sub-region (SBA) is bent.

[0052] Referring to FIGS. 2 and 3, a display panel (100) may include a substrate (SUB) comprising a main area (MA) and a sub area (SBA), and a circuit layer (TFTL), a light-emitting element layer (EML), an encapsulation layer (TFEL), a touch sensing layer (TSU), and a color filter layer (CFL) sequentially disposed on the substrate (SUB). The circuit layer (TFTL) may also be located in the main area (MA) and the sub area (SBA) on the substrate (SUB). The light-emitting element layer (EML) and the encapsulation layer (TFEL) may be located on a part of the substrate (SUB) and the circuit layer (TFTL). For example, the light-emitting element layer (EML) and the encapsulation layer (TFEL) may be located in the main area (MA).

[0053] In one embodiment, the display device (10) may further include additional elements disposed on the display panel (100).

Each of the polarizing layer and / or the protective layer may be manufactured integrally with the display panel (100) or manufactured separately from the display panel (100) and attached to the display panel (100) via an adhesive layer or the like.

[0054] The substrate (SUB) may include an insulating material such as a polymer resin. For example, the substrate (SUB) may be made of polyimide or other insulating materials. The substrate (SUB) may be a flexible substrate capable of deformation such as bending, folding, or rolling. Alternatively, the substrate (SUB) may include an insulating material such as glass.

[0055] The circuit layer (TFTL) may include pixel circuits and wiring. For example, the circuit layer (TFTL) may include circuit elements (e.g., pixel transistors and capacitors) constituting the pixel circuit of each pixel and wiring connected to the pixels. In one embodiment, the circuit layer (TFTL) may further include circuit elements constituting an embedded circuit, such as a scan driving circuit, and wiring connected to said embedded circuit.

[0056] The light-emitting element layer (EML) may include light-emitting elements disposed in light-emitting regions of pixels. For example, each pixel may include at least one light-emitting element and a pixel circuit connected to said light-emitting element. Each pixel may be located in a pixel region that includes a light-emitting region where the light-emitting element is disposed and a pixel circuit region where the pixel circuit is disposed. The light-emitting region and the pixel circuit region of each pixel may overlap each other, but are not limited thereto.

[0057] In describing the embodiments, the circuit layer (TFTL) and the light-emitting element layer (EML) have been described separately, but the embodiments are not limited thereto. For example, the circuit layer (TFTL) and the light-emitting element layer (EML) may be integrated.

[0058] The encapsulation layer (TFEL) covers the light-emitting element layer (EML) and extends into a non-display area (NA) to come into contact with the circuit layer (TFTL). In one embodiment, the encapsulation layer (TFEL) may have a multilayer structure comprising at least two inorganic encapsulation films that overlap each other and at least one organic encapsulation film interposed between the inorganic encapsulation films.

[0059] A touch sensing layer (TSU) may be disposed on an encapsulation layer (TFEL). The touch sensing layer (TSU) may include a plurality of touch electrodes for detecting a user's touch in a capacitive manner, and touch lines connecting the plurality of touch electrodes to a touch driving unit (400). For example, the touch sensing layer (TSU) may sense a user's touch in a mutual capacitance manner or a self-capacitance manner.

[0060] In another embodiment, the touch sensing layer (TSU) may be disposed on a separate substrate disposed on the display panel (100). In this case, the substrate supporting the touch sensing layer (TSU) may be a base member that encapsulates the display panel (100).

[0063] A color filter layer (CFL) may be disposed on a touch sensing layer (TSU). The color filter layer (CFL) may include a plurality of color filters corresponding to each of a plurality of light-emitting regions. Each of the color filters may selectively transmit light of a specific wavelength and block or absorb light of other wavelengths. The color filter layer (CFL) may absorb a portion of the light entering from outside the display device (10) to reduce reflected light caused by external light. Therefore, the color filter layer (CFL) can prevent color distortion caused by external light reflection.

[0064] Since the color filter layer (CFL) is placed directly on the touch sensing layer (TSU), the display device (10) may not require a separate substrate for the color filter layer (CFL). Therefore, the thickness of the display panel (100) may be relatively small.

[0065] In one embodiment, the display panel (100) may be bent in a bending area (BA). The bending area (BA) may be a part of a sub-area (SBA) and may be spaced apart from the main area (MA).

[0066] The substrate (SUB) and circuit layer (TFTL) can be bent in a bending area (BA) corresponding to a portion of the sub-region (SBA). Accordingly, the bezel area perceived by the user as a non-display area (NA) can be reduced or minimized.

[0067] Figure 4 is an enlarged view of area A of Figure 2.

[0068] FIG. 4 illustrates an arrangement of pixels (MDX, SDX) placed in a sub-display area (SDA) and a main display area (MDA) around the display area (DA) of a display device (10).

[0069] Referring to FIG. 4, the display area (DA) may include a main display area (MDA) and a sub display area (SDA). The sub display area (SDA) may be an area where a component is placed on the lower part of the substrate (SUB) of the display device (10). A plurality of main display pixels (MDX) may be arranged in the main display area (MDA), and a plurality of sub display pixels (SDX) may be placed in the sub display area (SDA). Each main display pixel (MDX) may include one or more main light-emitting areas (MEA), and each sub display pixel (SDX) may include one or more sub light-emitting areas (SEA). A light-emitting element (ED) (see FIG. 11) may be placed in each light-emitting area (MEA, SEA) to emit light.

[0070] In the main display area (MDA), a plurality of light-emitting elements (EDs) that emit light and pixel circuits electrically connected to the light-emitting elements (EDs) to apply signals for the light emission of the light-emitting elements (EDs) may be arranged. The main display area (MDA) may be an area in which the light-emitting elements (EDs) and pixel circuits are arranged in a specific arrangement. In the main display area (MDA), each of the light-emitting elements (EDs) may constitute a main light-emitting area (MEA), and a plurality of main light-emitting areas (MEAs) may constitute a single main display pixel (MDX). For example, four main light-emitting areas (MEAs) may constitute a single main display pixel (MDX). That is, a single main display pixel (MDX) may include four main light-emitting areas (MEAs), and the four main light-emitting areas (MEAs) may constitute a single main display pixel (MDX) to express a white gradation. The number of main light-emitting areas (MEAs) included in the main display pixel (MDX) is not limited thereto.

[0071] In some embodiments, a plurality of main display pixels (MDX) disposed in a main display area (MDA) may be arranged in a fourth direction (DR4) and a fifth direction (DR5), which are diagonal directions between a first direction (DR1) and a second direction (DR2). Additionally, a plurality of main light-emitting areas (MEA) of the main display pixels (MDX) may be arranged in a fourth direction (DR4) and a fifth direction (DR5).

[0072] Light-emitting light-emitting elements (ED) are arranged in the sub-display area (SDA) to form a sub-light-emitting area (SEA), and multiple sub-light-emitting areas (SEA) can form a single sub-display pixel (SDX). However, the sub-display area (SDA) is a component placed on the back surface of the substrate (SUB) of the display panel (100), and may be, for example, an area overlapping with an optical device, and may have a structure that takes into account the light transmittance, unlike the main display area (MDA).

[0073] The sub-display pixel (SDX) formed by a plurality of sub-emissive regions (SEA) of the sub-display region (SDA) may have an arrangement different from that of the main display pixel (MDX), but the embodiments of this specification are not limited thereto.

[0074] In some embodiments, a plurality of sub-display pixels (SDX) placed in a sub-display area (SDA) may be arranged in a fourth direction (DR4) and a fifth direction (DR5), which are diagonal directions between a first direction (DR1) and a second direction (DR2). Additionally, a plurality of sub-emissive areas (SEA) of sub-display pixels (SDX) may be arranged in a fourth direction (DR4) and a fifth direction (DR5).

[0075] The sub-display area (SDA) may further include transmission areas (TA) that transmit light. The transmission area (TA) is an area that passes light incident on the display panel (100).

[0076] The transmission region (TA) may be positioned adjacent to the sub-emissive regions (SEA). The transmission region (TA) may not overlap with the sub-emissive regions (SEA). The transmission region (TA) may be surrounded by the sub-emissive regions (SEA).

[0077] Multiple transmission regions (TA) can be arranged in a first direction (DR1). Sub-emissive regions (SEA) can be arranged between the first direction (DR1) and the second direction (DR2) of the multiple transmission regions (TA), as well as between the fourth direction (DR4) and the fifth direction (DR5).

[0078] Due to the transmission regions (TA), the number of sub-emissive regions (SEA) per unit area in the sub-display region (SDA) may differ from the number of main emissive regions (MEA) per unit area in the main display region (MDA). For example, the number of sub-emissive regions (SEA) per unit area in the sub-display region (SDA) may be smaller than the number of main emissive regions (MEA) per unit area in the main display region (MDA).

[0079] Additionally, due to the transmission regions (TA), the ratio of the area of ​​the sub-emissive regions (SEA) of the sub-display region (SDA) to the area of ​​the sub-display region (SDA) may differ from the ratio of the area of ​​the main emissive regions (MEA) of the main display region (MDA) to the area of ​​the main display region (MDA). For example, the ratio of the area of ​​the sub-emissive regions (SEA) of the sub-display region (SDA) to the area of ​​the sub-display region (SDA) may be smaller than the ratio of the area of ​​the main emissive regions (MEA) of the main display region (MDA) to the area of ​​the main display region (MDA).

[0080] FIG. 5 is a plan view showing a sub-display area according to one embodiment of the present specification.

[0081] Referring to FIG. 5, the sub-display area (SDA) may include a plurality of sub-display pixels. The plurality of sub-display pixels may be arranged in a fourth direction (DR4) and a fifth direction (DR5). The sub-display pixels may be repeatedly arranged throughout the entire sub-display area (SDA) as illustrated.

[0082] Each of the multiple sub-display pixels may include multiple sub-emissive regions (SEA). For example, each of the multiple sub-display pixels may include a first sub-emissive region (SEA1), a second sub-emissive region (SEA2), and a third sub-emissive region (SEA3). However, the number of sub-emissive regions (SEA) included in the sub-display pixels is not limited thereto and can be varied in many ways.

[0083] A sub-display pixel may include one or more light-emitting elements (EDs) (see FIG. 13). The one or more light-emitting elements (EDs) included in a sub-display pixel may emit the same or different colors. For example, a light-emitting element (ED) placed in a first sub-light-emitting region (SEA1) may emit a first red light, a light-emitting element (ED) placed in a second sub-light-emitting region (SEA2) may emit a second green light, and a light-emitting element (ED) placed in a third sub-light-emitting region (SEA3) may emit a third blue light, but the embodiments of this specification are not limited thereto.

[0084] In one embodiment, the sub-display area (SDA) may include a transmission area (TA). The transmission area (TA) may be arranged to be aligned in a second direction (DR2). The transmission area (TA) may include a first transmission area (TA1) where an alternative pattern is placed and a second transmission area (TA2) where a second common electrode is placed. The second transmission area (TA2) may be arranged to surround the first transmission area (TA1).

[0085] Any one of the transmission regions (TA) may be arranged to surround the second sub-luminous region (SEA2). In one embodiment, the first sub-luminous region (SEA1), the independently existing second sub-luminous region (SEA2), the third sub-luminous region (SEA3), the second sub-luminous region (SEA2) surrounded by the second transmission region (TA2), and the first transmission region (TA1) and the second transmission region (TA2) arranged in the first direction (DR1) from the independently existing second sub-luminous region (SEA2) may form a single unit. A single unit arranged in the sub-display region (SDA) may be arranged repeatedly with respect to one another.

[0086] The embodiment may include a first pixel defining film arranged to define a main light-emitting region and a sub-light-emitting region (SEA1, SEA2, SE), a first spacer arranged on the first pixel defining film, and a first common electrode arranged on the first pixel defining film and the first spacer. In other words, the pixel defining film arranged to define a main light-emitting region and a sub-light-emitting region (SEA1, SEA2, SEA3) and the spacer arranged thereon may each be the first pixel defining film and the first spacer.

[0087] The transmission region (TA) may be defined by a light-blocking layer as described below. An embodiment may include a second pixel defining film disposed in the transmission region (TA), a second spacer disposed on the second pixel defining film, and a second common electrode disposed on the second pixel defining film and the second spacer. In other words, the pixel defining film and the spacer disposed in the transmission region defined by the light-blocking layer may each be the second pixel defining film and the second spacer.

FIG. 9 is a layout diagram showing a second color filter layer in a main display pixel according to an embodiment of the present specification. FIG. 10 is a layout diagram showing a third color filter layer in a main display pixel according to an embodiment of the present specification.

[0089] Referring to FIGS. 6 to 10, the main display area (MDA) may include a plurality of main display pixels (MDX). For example, the main display area (MDA) may include a first main display pixel (MDX1), a second main display pixel (MDX2), a third main display pixel (MDX3), and a fourth main display pixel (MDX4).

[0090] Multiple main display pixels (MDX) can be arranged in a fourth direction (DR4) and a fifth direction (DR5). For example, the first main display pixel (MDX1) and the second main display pixel (MDX2) can be arranged in the fifth direction (DR5), the second main display pixel (MDX2) and the third main display pixel (MDX3) can be arranged in the fourth direction (DR4), the third main display pixel (MDX3) and the fourth main display pixel (MDX4) can be arranged in the fifth direction (DR5), and the fourth main display pixel (MDX4) and the first main display pixel (MDX1) can be arranged in the fourth direction (DR4). The first to fourth main display pixels (MDX1, MDX2, MDX3, MDX4) can be repeatedly arranged throughout the entire main display area (MDA) as illustrated.

[0091] A plurality of main display pixels (MDX) may each include a plurality of main light-emitting regions (MEA). For example, a plurality of main display pixels (MDX) may each include a first main light-emitting region (MEA1), a second main light-emitting region (MEA2), a third main light-emitting region (MEA3), and a fourth main light-emitting region (MEA4). The fourth main light-emitting region (MEA4) may be substantially the same as the second main light-emitting region (MEA2). However, the number of main light-emitting regions (MEA) included in the main display pixels (MDX) is not limited thereto and can be varied in many ways.

[0092] A main display pixel (MDX) may include one or more light-emitting elements (ED) (see FIG. 11). The one or more light-emitting elements (ED) included in a main display pixel (MDX) may emit the same or different colors. For example, a light-emitting element (ED) placed in a first main light-emitting area (MEA1) may emit a first red light, a light-emitting element (ED) placed in a second main light-emitting area (MEA2) may emit a second green light, and a light-emitting element (ED) placed in a third main light-emitting area (MEA3) may emit a third blue light. A light-emitting element (ED) placed in a fourth main light-emitting area (MEA4) may emit the second green light, but is not limited thereto.

[0093] The main light-emitting region (MEA) may be an area where the light-emitting layer (EL) (see FIG. 11) overlaps with the pixel electrodes (AE1, AE2, AE3) (see FIG. 11). For example, an opening of the first pixel defining film (PDL1) (see FIG. 11) may correspond to the main light-emitting region (MEA). For example, each of the main light-emitting regions (MEA) may be defined by a plurality of openings of the first pixel defining film (PDL1) of the light-emitting element layer (EML) (see FIG. 11).

[0094] A first main light-emitting region (MEA1) may be defined by a first opening of a first pixel defining film (PDL1) that overlaps with a first pixel electrode (AE1) (see FIG. 11), a second main light-emitting region (MEA2) may be defined by a second opening of a first pixel defining film (PDL1) that overlaps with a second pixel electrode (AE2) (see FIG. 11), and a third main light-emitting region (MEA3) may be defined by a third opening of a first pixel defining film (PDL1) that overlaps with a third pixel electrode (AE3) (see FIG. 11). Although not shown in the drawings, a fourth main light-emitting region (MEA4) may be defined by a fourth opening of a first pixel defining film (PDL1) that overlaps with a fourth pixel electrode.

[0095] Multiple main light-emitting regions (MEA) may be arranged in a pentile type, for example, a diamond pentile type. For example, the first main light-emitting region (MEA1) and the third main light-emitting region (MEA3) may be spaced apart from each other in a first direction (DR1) and may be repeatedly arranged alternately in the first direction (DR1) and the second direction (DR2). The second main light-emitting region (MEA2) and the fourth main light-emitting region (MEA4) may be spaced apart in the second direction (DR2). The second main light-emitting region (MEA2) and the fourth main light-emitting region (MEA4) may be spaced apart from the adjacent first main light-emitting region (MEA1) and third main light-emitting region (MEA3) in a fourth direction (DR4) or a fifth direction (DR5). The second main light-emitting region (MEA2) and the fourth main light-emitting region (MEA4) may be alternately and repeatedly arranged along the first direction (DR1) and the second direction (DR2), and the second main light-emitting region (MEA2) and the first main light-emitting region (MEA1), or the fourth main light-emitting region (MEA4) and the third main light-emitting region (MEA3) may be alternately and repeatedly arranged along the fourth direction (DR4) or the fifth direction (DR5).

[0096] In the first diagonal column (C1), the first main light-emitting area (MEA1) and the fourth main light-emitting area (MEA4) of the first main display pixel (MDX1) and the first main light-emitting area (MEA1) and the fourth main light-emitting area (MEA4) of the second main display pixel (MDX2) may be arranged in the fifth direction (DR5). In the second diagonal column (C2), the second main light-emitting area (MEA2) and the third main light-emitting area (MEA3) of the first main display pixel (MDX1) and the second main light-emitting area (MEA2) and the third main light-emitting area (MEA3) of the second main display pixel (MDX2) may be arranged in the fifth direction (DR5). In the third diagonal column (C3), the first main light-emitting area (MEA1) and the fourth main light-emitting area (MEA4) of the fourth main display pixel (MDX4) and the first main light-emitting area (MEA1) and the fourth main light-emitting area (MEA4) of the third main display pixel (MDX3) may be arranged in the fifth direction (DR5). In the fourth diagonal column (C4), the second main light-emitting area (MEA2) and the third main light-emitting area (MEA3) of the fourth main display pixel (MDX4) and the second main light-emitting area (MEA2) and the third main light-emitting area (MEA3) of the third main display pixel (MDX3) may be arranged in the fifth direction (DR5).

[0097] In the first diagonal row (R1), the first main light-emitting area (MEA1) and the second main light-emitting area (MEA2) of the first main display pixel (MDX1) and the first main light-emitting area (MEA1) and the second main light-emitting area (MEA2) of the fourth main display pixel (MDX4) may be arranged in the fourth direction (DR4). In the second diagonal row (R2), the fourth main light-emitting area (MEA4) and the third main light-emitting area (MEA3) of the first main display pixel (MDX1) and the fourth main light-emitting area (MEA4) and the third main light-emitting area (MEA3) of the fourth main display pixel (MDX4) may be arranged in the fourth direction (DR4). In the third diagonal row (R3), the first main light-emitting area (MEA1) and the second main light-emitting area (MEA2) of the second main display pixel (MDX2) and the first main light-emitting area (MEA1) and the second main light-emitting area (MEA2) of the third main display pixel (MDX3) may be arranged in the fourth direction (DR4). In the fourth diagonal row (R4), the fourth main light-emitting area (MEA4) and the third main light-emitting area (MEA3) of the second main display pixel (MDX2) and the fourth main light-emitting area (MEA4) and the third main light-emitting area (MEA3) of the third main display pixel (MDX3) may be arranged in the fourth direction (DR4).

[0098] In an exemplary embodiment, the area or size of the first to fourth main light-emitting regions (MEA1, MEA2, MEA3, MEA4) may differ from one another. As illustrated, the area of ​​the first main light-emitting region (MEA1) may be larger than the areas of the second main light-emitting region (MEA2), the third main light-emitting region (MEA3), and the fourth main light-emitting region (MEA4), and the area of ​​the third main light-emitting region (MEA3) may be larger than the areas of the second main light-emitting region (MEA2) and the fourth main light-emitting region (MEA4). The intensity of the emitted light may vary depending on the area of ​​each main light-emitting region (MEA), and the color tone of the screen displayed on the display device (10) can be controlled by adjusting the area of ​​each main light-emitting region (MEA). In the illustrated embodiment, the area of ​​the first main light-emitting region (MEA1) is shown as the largest, but it is not limited thereto. The size and area of ​​each main light-emitting region (MEA) can be freely adjusted according to the color tone of the screen required by the display device (10). In addition, the area of ​​each main light-emitting region (MEA) is related to light efficiency, the lifespan of the light-emitting element (ED), etc., and may have a trade-off relationship with reflection by external light. The area of ​​each main light-emitting region (MEA) can be adjusted by taking the above factors into consideration.

[0099] In the drawings, the planar shape of each of the main light-emitting regions (MEA) is depicted as circular, but is not limited thereto.

[0100] The display device (10) may include a light-blocking layer (BM), a first color filter layer (CFL1), a second color filter layer (CFL2), and a third color filter layer (CFL3) disposed on the light-blocking layer (BM).

[0101] The light-blocking layer (BM) can be placed across the entire display area (DA). For example, the light-blocking layer (BM) can be placed across the main display area (MDA) and the sub-display area (SDA).

[0102] The light-blocking layer (BM) may include a plurality of main apertures (OPT_M) disposed in the main display area (MDA) and respectively corresponding to the main light-emitting area (MEA). In other words, the plurality of main apertures (OPT_M) may be defined by the light-blocking layer (BM). The light-blocking layer (BM) may cover the main display area (MDA), excluding the area in the main display area (MDA) where the plurality of main apertures (OPT_M) are disposed. The plurality of main apertures (OPT_M) of the light-blocking layer (BM) may be areas where light emitted from a light-emitting element (ED) corresponding to the main light-emitting area (MEA) is emitted.

[0103] A plurality of main openings (OPT_M) may include a first main opening (OPT1_M) overlapping with first main light-emitting regions (MEA1), a second main opening (OPT2_M) overlapping with second main light-emitting regions (MEA2), a third main opening (OPT3_M) overlapping with third main light-emitting regions (MEA3), and a fourth main opening (OPT4_M) overlapping with fourth main light-emitting regions (MEA4).

[0104] Each of the plurality of main openings (OPT_M) may have a planar area larger than the planar area of ​​each main light-emitting region (MEA). For example, the first main opening (OPT1_M) may have a planar area larger than the first main light-emitting region (MEA1), the second main opening (OPT2_M) may have a planar area larger than the second main light-emitting region (MEA2), the third main opening (OPT3_M) may have a planar area larger than the third main light-emitting region (MEA3), and the fourth main opening (OPT4_M) may have a planar area larger than the fourth main light-emitting region (MEA4).

[0105] A first color filter layer (CFL1) may be disposed on a light-blocking layer (BM). A second color filter layer (CFL2) may be disposed on the first color filter layer (CFL1). A third color filter layer (CFL3) may be disposed on the second color filter layer (CFL2).

[0106] The first color filter layer (CFL1) may include a first main color portion (CF1_M) disposed in the main display area (MDA), the second color filter layer (CFL2) may include a second main color portion (CF2_M) and a fourth main color portion (CF4_M) disposed in the main display area (MDA), and the third color filter layer (CFL3) may include a third main color portion (CF3_M) disposed in the main display area (MDA). The first to fourth main color portions (CF1_M, CF2_M, CF3_M, CF4_M) may be included in the main color portion (CF_M).

[0107] The main color section (CF_M) may include a colorant, such as a dye or pigment, that absorbs light of a wavelength other than that of a specific wavelength, and may be positioned to correspond to the color of the light emitted by the light-emitting element (ED). For example, the first main color section (CF1_M) may be a red color filter that is positioned to overlap with the first main light-emitting region (MEA1) and transmits only the first red light. The second main color section (CF2_M) may be a green color filter that is positioned to overlap with the second main light-emitting region (MEA2) and transmits only the second green light. The third main color section (CF3_M) may be a blue color filter that is positioned to overlap with the third main light-emitting region (MEA3) and transmits only the third blue light, and the fourth main color section (CF4_M) may be a green color filter that is positioned to overlap with the fourth main light-emitting region (MEA4) and transmits only the second green light.

[0108] A plurality of main color sections (CF_M) may each be arranged corresponding to a plurality of main light-emitting regions (MEA). For example, a first main color section (CF1_M) may be superimposed on a first main light-emitting region (MEA1), a second main color section (CF2_M) may be superimposed on a second main light-emitting region (MEA2), a third main color section (CF3_M) may be superimposed on a third main light-emitting region (MEA3), and a fourth main color section (CF4_M) may be superimposed on a fourth main light-emitting region (MEA4).

[0109] Similar to the arrangement of the main light-emitting regions (MEA), the main color sections (CF_M) may be arranged in a pentile type, for example, a diamond pentile type. For example, the first main color section (CF1_M) and the third main color section (CF3_M) may be spaced apart from each other in a first direction (DR1) and may be repeatedly arranged alternately in the first direction (DR1) and the second direction (DR2). The second main color section (CF2_M) and the fourth main color section (CF4_M) may be spaced apart in the second direction (DR2). The second main color section (CF2_M) and the fourth main color section (CF4_M) may be spaced apart from the adjacent first main color section (CF1_M) and third main color section (CF3_M) in a fourth direction (DR4) or a fifth direction (DR5). The second main color section (CF2_M) and the fourth main color section (CF4_M) may be alternately and repeatedly arranged along the first direction (DR1) and the second direction (DR2), and the second main color section (CF2_M) and the first main color section (CF1_M), or the fourth main color section (CF4_M) and the third main color section (CF3_M) may be alternately and repeatedly arranged along the fourth direction (DR4) or the fifth direction (DR5).

[0110] Each of the plurality of main color sections (CF_M) may have a different size or area on a plane. As described above, the size or area of ​​each of the plurality of main light-emitting regions (MEA) may differ from one another, and accordingly, the size or area of ​​the plurality of main color sections (CF_M) on a plane may also differ from one another. For example, the size or area of ​​the first main color section (CF1_M) may be larger than the size or area of ​​the second main color section (CF2_M), the third main color section (CF3_M), and the fourth main color section (CF4_M). Additionally, the size or area of ​​the third main color section (CF3_M) may be larger than the size or area of ​​the second main color section (CF2_M) and the fourth main color section (CF4_M).

[0111] Each of the plurality of main color sections (CF_M) may have a planar area larger than the planar area of ​​each main light-emitting region (MEA). For example, the first main color section (CF1_M) may have a planar area larger than the first main light-emitting region (MEA1), the second main color section (CF2_M) may have a planar area larger than the second main light-emitting region (MEA2), the third main color section (CF3_M) may have a planar area larger than the third main light-emitting region (MEA3), and the fourth main color section (CF4_M) may have a planar area larger than the fourth main light-emitting region (MEA4).

[0112] A plurality of main color sections (CF_M) may each be arranged corresponding to a plurality of main openings (OPT_M) of the light-blocking layer (BM). For example, a first main color section (CF1_M) may be superimposed on the first main opening (OPT1_M) of the light-blocking layer (BM), a second main color section (CF2_M) may be superimposed on the second main opening (OPT2_M) of the light-blocking layer (BM), a third main color section (CF3_M) may be superimposed on the third main opening (OPT3_M) of the light-blocking layer (BM), and a fourth main color section (CF4_M) may be superimposed on the fourth main opening (OPT4_M) of the light-blocking layer (BM).

[0113] Each of the plurality of main color sections (CF_M) may have a planar area larger than the planar area of ​​each of the main openings (OPT_M) of the shading layer (BM). For example, the first main color section (CF1_M) may have a planar area larger than the first main opening (OPT1_M) of the shading layer (BM), the second main color section (CF2_M) may have a planar area larger than the second main opening (OPT2_M) of the shading layer (BM), the third main color section (CF3_M) may have a planar area larger than the third main opening (OPT3_M) of the shading layer (BM), and the fourth main color section (CF4_M) may have a planar area larger than the fourth main opening (OPT4_M) of the shading layer (BM). Accordingly, each of the multiple main color sections (CF_M) can completely cover the main openings (OPT_M) of the shading layer (BM).

[0114] In the drawing, the planar shape of each of the main color parts (CF_M) is depicted as circular, but is not limited thereto.

[0115] FIG. 11 is a cross-sectional view showing a portion cut along the X2-X2' line of FIG. 6.

[0116] FIG. 11 illustrates a cross-section across the first to third main light-emitting regions (MEA1, MEA2, MEA3) of the first main display pixel (MDX1) in the main display area (MDA). The fourth main light-emitting region (MEA4) is assumed to have substantially the same structure as the second main light-emitting region (MEA2), and a repetitive description is omitted.

[0121] The lower metal layer (BML) may be disposed on the first buffer layer (BF1). For example, the lower metal layer (BML) may be formed as a single layer or a multilayer composed of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or an alloy thereof.

[0122] The second buffer layer (BF2) may cover the first buffer layer (BF1) and the lower metal layer (BML).

For example, the second buffer layer (BF2) may include a plurality of inorganic films stacked alternately.

[0123] A thin-film transistor (TFT) can be placed on a second buffer layer (BF2) and can form a pixel circuit for each of a plurality of pixels. For example, the thin-film transistor (TFT) may be a driving transistor or a switching transistor of a pixel circuit. The thin-film transistor (TFT) may include a semiconductor layer (ACT), a source electrode (SE), a drain electrode (DE), and a gate electrode (GE).

[0134] A light-emitting element layer (EML) may be disposed on a thin-film transistor layer (TFTL). The light-emitting element layer (EML) may include a light-emitting element (ED) and a first pixel defining film (PDL1). The light-emitting element (ED) may include pixel electrodes (AE1, AE2, AE3), a light-emitting layer (EL), and a first common electrode (CE1). The first common electrode (CE1) may be a common electrode disposed in a plurality of light-emitting regions included in a main light-emitting region (MEA) and a sub-light-emitting region (SEA). Accordingly, the first common electrode (CE1) may be disposed on the first pixel defining film (PDL1) and the first spacers (SPC1_M, SPC2_M, SPC3_M).

[0135] Pixel electrodes (AE1, AE2, AE3) may be disposed on the second protective layer (PAS2). Different pixel electrodes (AE1, AE2, AE3) may each be disposed to overlap with any one of the different openings of the first pixel defining film (PDL1). Pixel electrodes (AE1, AE2, AE3) may be electrically connected to the drain electrode (DE) of the thin-film transistor (TFT) through the first and second connecting electrodes (CNE1, CNE2).

[0136] The light-emitting layer (EL) may be placed on the pixel electrodes (AE1, AE2, AE3). For example, the light-emitting layer (EL) may be an organic light-emitting layer made of an organic material, but is not limited thereto. When the light-emitting layer (EL) corresponds to an organic light-emitting layer, a thin-film transistor (TFT) applies a predetermined voltage to the pixel electrodes (AE1, AE2, AE3) of the light-emitting element (ED), and when the first common electrode (CE1) of the light-emitting element (ED) receives a common voltage or a cathode voltage, holes and electrons can each move to the light-emitting layer (EL) through the hole transport layer and the electron transport layer, and the holes and electrons can combine with each other in the light-emitting layer (EL) to emit light.

[0137] In an exemplary embodiment, light-emitting layers (ELs) disposed on different pixel electrodes (AE1, AE2, AE3) may emit light of different colors. For example, a light-emitting layer disposed on the first pixel electrode (AE1) may emit red light of a first color, a light-emitting layer disposed on the second pixel electrode (AE2) may emit green light of a second color, and a light-emitting layer disposed on the third pixel electrode (AE3) may emit blue light of a third color. However, this is not limited thereto. In another embodiment, the light-emitting layer (EL) may be disposed as a single common layer on the different pixel electrodes (AE1, AE2, AE3) and the first pixel defining film (PDL1), and the light-emitting layer (EL) disposed on the different pixel electrodes (AE1, AE2, AE3) may emit light of the same color. In this case, the display device (10) may further include a color adjustment layer disposed on the light-emitting elements (ED).

[0138] The first common electrode (CE1) can be placed on the light-emitting layer (EL). For example, the first common electrode (CE1) can be implemented in the form of an electrode common to all pixels without being separated by a plurality of pixels. The first common electrode (CE1) can be placed on the light-emitting layer (EL) at the pixel electrodes (AE1, AE2, AE3) and can be placed on the first pixel defining film (PDL1) in the area excluding the pixel electrodes (AE1, AE2, AE3).

[0139] The first common electrode (CE1) can receive a common voltage or a low potential voltage. When the pixel electrodes (AE1, AE2, AE3) receive a voltage corresponding to the data voltage and the first common electrode (CE1) receives a low potential voltage, a potential difference is formed between the pixel electrodes (AE1, AE2, AE3) and the first common electrode (CE1), thereby allowing the light-emitting layer (EL) to emit light.

[0140] The first pixel defining film (PDL1) may be disposed on a portion of the second protective layer (PAS2) and pixel electrodes (AE1, AE2, AE3) and may include a plurality of openings. The first pixel defining film (PDL1) may be a pixel defining film that defines a plurality of light-emitting regions included in the main light-emitting region (MEA) and the sub-light-emitting region (SEA). Each opening of the first pixel defining film (PDL1) may expose a portion of the pixel electrodes (AE1, AE2, AE3). As described above, each of the openings of the first pixel defining film (PDL1) may define the first to third main light-emitting regions (MEA1, MEA2, MEA3), and their areas or sizes may differ from each other. The first pixel defining film (PDL1) may separate and insulate the pixel electrodes (AE1, AE2, AE3) of each of the plurality of light-emitting elements (ED).

[0141] The first pixel defining film (PDL1) may include a light-absorbing material to prevent light reflection. For example, the first pixel defining film (PDL1) may include a polyimide (PI)-based binder and a pigment mixed with red, green, and blue. Alternatively, the first pixel defining film (PDL1) may include a cardo-based binder resin and a mixture of a lactam-based black pigment and a blue pigment. Alternatively, the first pixel defining film (PDL1) may include carbon black.

[0142] The first spacers (SPC1_M, SPC2_M, SPC3_M) placed in the main display area (MDA) may be placed on the first pixel defining film (PDL1). The first spacers (SPC1_M, SPC2_M, SPC3_M) may be spacers placed on the first pixel defining film (PDL1) which defines a plurality of light-emitting areas included in the main light-emitting area (MEA) and the sub-light-emitting area (SEA).

[0143] The first spacer (SPC1_M, SPC2_M, SPC3_M) can serve to support the mask during the process of manufacturing the light-emitting layer (EL). The first spacer (SPC1_M, SPC2_M, SPC3_M) 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.

[0144] The encapsulation layer (TFEL) is disposed on the first common electrode (CE1) and can cover a plurality of light-emitting elements (ED). The encapsulation layer (TFEL) may include at least one inorganic film to prevent oxygen or moisture from penetrating into the light-emitting element layer (EML). The encapsulation layer (TFEL) may include at least one organic film to protect the light-emitting element layer (EML) from foreign substances such as dust.

[0145] In an exemplary embodiment, the encapsulation layer (TFEL) may include a first encapsulation layer (TFE1), a second encapsulation layer (TFE2), and a third encapsulation layer (TFE3). The first encapsulation layer (TFE1) and the third encapsulation layer (TFE3) are inorganic encapsulation layers, and the second encapsulation layer (TFE2) disposed between them may be an organic encapsulation layer.

[0146] The first encapsulation layer (TFE1) and the third encapsulation layer (TFE3) may each include one or more inorganic insulating materials. The inorganic insulating materials may include aluminum oxide, titanium oxide, tantalum oxide, hafnium oxide, zinc oxide, silicon oxide, silicon nitride, and / or silicon oxynitride.

[0147] The second encapsulation layer (TFE2) may include a polymer-based material. Polymer-based materials may include acrylic resins, epoxy resins, polyimide, and polyethylene. For example, the second encapsulation layer (TFE2) may include an acrylic resin, such as polymethyl methacrylate or polyacrylic acid. The second encapsulation layer (TFE2) may be formed by curing a monomer or by applying a polymer.

[0148] A touch sensing layer (TSU) may be disposed on an encapsulation layer (TFEL). The touch sensing layer (TSU) may include a first touch insulating layer (SIL1), a second touch insulating layer (SIL2), a touch electrode (TL), and a third touch insulating layer (SIL3).

[0149] The first touch insulating layer (SIL1) may be disposed on the encapsulation layer (TFEL). The first touch insulating layer (SIL1) may have insulating and optical functions. The first touch insulating layer (SIL1) may include at least one inorganic film. Optionally, the first touch insulating layer (SIL1) may be omitted.

[0150] The second touch insulating layer (SIL2) may cover the first touch insulating layer (SIL1). Although not shown in the drawing, another layer of touch electrodes may be disposed on the first touch insulating layer (SIL1), and the second touch insulating layer (SIL2) may cover these touch electrodes (TL). The second touch insulating layer (SIL2) may have insulating and optical functions. For example, the second touch insulating layer (SIL2) may be an inorganic film comprising at least one of a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, and an aluminum oxide layer.

[0151] Some of the touch electrodes (TL) may be placed on the second touch insulating layer (SIL2). Each touch electrode (TL) may not overlap with the pixel electrodes (AE1, AE2, AE3). Each touch electrode (TL) may be formed as a single layer of molybdenum (Mo), titanium (Ti), copper (Cu), aluminum (Al), or indium tin oxide (ITO), or 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).

[0152] The touch electrode (TL) of the touch sensing layer (TSU) may have a certain line width and be arranged to overlap with the light-shielding layer (BM). The light-shielding layer (BM) may have a width sufficient to completely cover the touch electrode (TL). In some embodiments, the touch electrode (TL) may be arranged so that its center is substantially parallel to the center of the light-shielding layer (BM), and the distance from one side of the touch electrode (TL) to one side of the light-shielding layer (BM) may be substantially the same as the distance from the other side of the touch electrode (TL) to the other side of the light-shielding layer (BM).

[0153] The third touch insulating layer (SIL3) may cover the touch electrode (TL) and the second touch insulating layer (SIL2). The third touch insulating layer (SIL3) may have insulating and optical functions. The third touch insulating layer (SIL3) may be made of the material exemplified in the second touch insulating layer (SIL2).

[0154] The color filter layer (CFL) may include a light-blocking layer (BM), a main color portion (CF_M), and an overcoat layer (OC).

[0155] The light-blocking layer (BM) may be disposed on the third touch insulating layer (SIL3) of the touch sensing layer (TSU). The light-blocking layer (BM) may be disposed overlapping the conductive line of the touch electrode (TL). The light-blocking layer (BM) may be disposed overlapping the first pixel defining film (PDL1) in the third direction (DR3).

[0156] The light-blocking layer (BM) may include a plurality of main openings (OPT_M) that are arranged to overlap with the main light-emitting regions (MEA). For example, the first main opening (OPT1_M) may overlap with the first main light-emitting region (MEA1) in the third direction (DR3), the second main opening (OPT2_M) may overlap with the second main light-emitting region (MEA2) in the third direction (DR3), and the third main opening (OPT3_M) may overlap with the third main light-emitting region (MEA3) in the third direction (DR3). Although not shown in the drawings, the fourth main opening (OPT4_M) may overlap with the fourth main light-emitting region (MEA4) in the third direction (DR3).

[0157] The area or size of each main aperture (OPT_M) may be larger than the area or size of the main light-emitting area (MEA). Additionally, the area or size of each main aperture (OPT_M) may be formed to be larger than the openings of the first pixel defining film (PDL1), and the light emitted from the light-emitting element (ED) may be visible to the user not only from the front but also from the side of the display device (10).

[0158] The light-blocking layer (BM) may include a light-absorbing material. For example, the light-blocking layer (BM) may include an inorganic black pigment or an organic black pigment. The inorganic black pigment may be carbon black, and the organic black pigment may include at least one of lactam black, perylene black, and aniline black, but is not limited thereto.

[0159] The main color portion (CF_M) of the color filter layer (CFL) may include the first main color portion (CF1_M) of the first color filter layer (CFL1), the second main color portion (CF2_M) of the second color filter layer (CFL2), and the third main color portion (CF3_M) of the third color filter layer (CFL3). Although not shown in the drawing, the main color portion (CF_M) may further include the fourth main color portion (CF4_M) of the second color filter layer (CFL2).

[0160] Main color sections (CF_M) can each be arranged corresponding to main light emission regions (MEA). For example, the first main color section (CF1_M) can be arranged overlappingly with the first main light emission region (MEA1) in the third direction (DR3), the second main color section (CF2_M) can be arranged overlappingly with the second main light emission region (MEA2) in the third direction (DR3), and the third main color section (CF3_M) can be arranged overlappingly with the third main light emission region (MEA3) in the third direction (DR3).

[0161] The main color sections (CF_M) can each be arranged to correspond to the main openings (OPT_M) of the shading layer (BM). For example, the first main color section (CF1_M) can cover the first main opening (OPT1_M), the second main color section (CF2_M) can cover the second main opening (OPT2_M), and the third main color section (CF3_M) can cover the third main opening (OPT3_M).

[0162] The widths of the main color sections (CF_M) may be larger than the widths of the main openings (OPT_M) of the shading layer (BM). For example, the width of the first main color section (CF1_M) may be larger than the width of the first main opening (OPT1_M) of the shading layer (BM), the width of the second main color section (CF2_M) may be larger than the width of the second main opening (OPT2_M) of the shading layer (BM), and the width of the third main color section (CF3_M) may be larger than the width of the third main opening (OPT3_M) of the shading layer (BM).

[0163] The overcoat layer (OC) may be disposed on the light-blocking layer (BM), the first color filter layer (CFL1), the second color filter layer (CFL2), and the third color filter layer (CFL3). The overcoat layer (OC) may be disposed across the entire front surface of the display area (DA) to flatten the upper surface of the display panel (100). The overcoat layer (OC) may be a colorless, light-transmitting layer that does not have a color in the visible light band. For example, the overcoat layer (OC) may include a colorless, light-transmitting organic material such as an acrylic resin.

[0164] FIG. 12 is a partial enlarged view showing the J region of FIG. 5. FIG. 13 is a cross-sectional view showing a section cut along the X3-X3' line of FIG. 12. FIG. 14 is a cross-sectional view showing a section cut along the X4-X4' line of FIG. 12.

[0165] Referring to FIGS. 12 to 14, the sub-emissive region (SEA) may be an area where the light-emitting layer (EL) overlaps with the pixel electrodes (AE1, AE2, AE3). For example, an opening of the first pixel defining film (PDL1) may correspond to the sub-emissive region (SEA). For example, each of the sub-emissive regions (SEA) may be defined by a plurality of openings of the first pixel defining film (PDL1) of the light-emitting element layer (EML).

[0166] A first sub-emissive region (SEA1) is defined by a first opening of a first pixel defining film (PDL1) that overlaps with a first pixel electrode (AE1), a second sub-emissive region (SEA2) is defined by a second opening of a first pixel defining film (PDL1) that overlaps with a second pixel electrode (AE2), and a third sub-emissive region (SEA3) can be defined by a third opening of a first pixel defining film (PDL1) that overlaps with a third pixel electrode (AE3).

[0167] In exemplary embodiments, the areas or sizes of the first to third sub-emissive regions (SEA1, SEA2, SEA3) may differ from one another. As illustrated, the area of ​​the third sub-emissive region (SEA3) may be larger than the areas of the first sub-emissive region (SEA1) and the second sub-emissive region (SEA2), and the area of ​​the first sub-emissive region (SEA1) may be larger than the area of ​​the second sub-emissive region (SEA2). However, it is not limited thereto. The intensity of emitted light may vary depending on the area of ​​each sub-emissive region (SEA), and the color tone of the screen can be controlled by adjusting the area of ​​each sub-emissive region (SEA). The area of ​​each sub-emissive region (SEA) is related to light efficiency, the lifespan of the light-emitting element (ED), etc., and may have a trade-off relationship with reflection caused by external light. The area of ​​each sub-emissive region (SEA) may be adjusted in consideration of the above factors.

[0168] In the drawings, the planar shape of each sub-emissive region (SEA) is depicted as a rhombus, but is not limited thereto. Additionally, the planar shape of each sub-emissive region (SEA) is depicted as being different from the planar shape of each main emissive region (MEA) described above, but the embodiments of this specification are not limited thereto. The shapes may be different as depicted, but they may be similar to each other to ensure uniformity in the manufacturing process.

[0169] The sub-display area (SDA) may further include a transparent area (TA). As described above, the transparent area (TA) may include a first transparent area (TA1) and a second transparent area (TA2). The first transparent area (TA1) may be positioned to be surrounded by the second transparent area (TA2). In the cross-sectional view, the first transparent area (TA1) may be positioned between the second transparent area (TA2).

[0170] The first transmission region (TA1) includes an alternative pattern, and the second transmission region (TA2) may include a second common electrode. The second common electrode may be a common electrode disposed in the transmission region (TA) defined by the light-blocking layer.

[0171] The boundary of the first transmission area (TA1) may be positioned so as to be spaced apart from the first sub-emissive area (SEA1) by a first distance (L1), from the second sub-emissive area (SEA2) by a second distance (L2), and from the third sub-emissive area (SEA3) by a third distance (L3). An alternative pattern may be placed in the first transmission area (TA1). Due to the material included in the alternative pattern, any gas may be emitted during the manufacturing process of the display device, and outgassing may occur. The embodiment can prevent the phenomenon of shrinkage of the emission area caused by outgassing by forming the boundary of the first transmission area (TA1) so as to be spaced apart from the boundaries of the first sub-emissive area (SEA1), the second sub-emissive area (SEA2), and the third sub-emissive area (SEA3) by a first distance (L1), a second distance (L2), and a third distance (L3), respectively. The boundary of the first transmission region (TA1) may be substantially identical to the boundary of the alternative pattern.

[0172] The first sub-emissive region (SEA1), the second sub-emissive region (SEA2), and the third sub-emissive region (SEA3) may all have different sizes. In this case, the first distance (L1), the second distance (L2), and the third distance (L3) may all be different. In one embodiment, the smallest value among the first distance (L1), the second distance (L2), and the third distance (L3) may be set to be greater than or equal to a preset value. For example, the third distance (L3) may be the smallest among the first distance (L1), the second distance (L2), and the third distance (L3). If the third distance (L3) is formed or designed to be greater than or equal to a preset value, the first distance (L1) and the second distance (L2) may also be formed or designed to be greater than or equal to a preset value. In one embodiment, the preset value may be 8 μm or greater. Or, it may be 9 μm or greater. Or, it may be 10 μm or greater. Or, it may be 11 μm or greater. Or, it may be 12㎛ or more. Or, it may be 13㎛ or more.

[0173] The display device (10) may include a light-blocking layer (BM) and a color filter layer (CFL) disposed on the light-blocking layer (BM). With respect to the sub-display area (SDA), the color filter layer (CFL) is described without being divided into multiple parts. However, all descriptions regarding the color filter layer (CFL) disposed in the main display area (MDA) described above may be applied to the sub-display area (SDA).

[0174] The light-blocking layer (BM) can be placed across the entire display area (DA). For example, the light-blocking layer (BM) can be placed in the main display area (MDA) and the sub-display area (SDA).

[0175] The light-blocking layer (BM) may include a plurality of sub-apertures (OPT_S) disposed in the sub-display area (SDA) and respectively corresponding to the sub-emission area (SEA). In other words, the plurality of sub-apertures (OPT_S) may be defined by the light-blocking layer (BM). The light-blocking layer (BM) may cover the sub-display area (SDA), excluding the area in the sub-display area (SDA) where the plurality of sub-apertures (OPT_S) are disposed. The plurality of sub-apertures (OPT_S) of the light-blocking layer (BM) may be areas from which light emitted from a light-emitting element (ED) corresponding to the sub-emission area (SEA) is emitted.

[0176] A plurality of sub-openings (OPT_S) may include a first sub-opening (OPT1_S) overlapping with first sub-luminous regions (SEA1), a second sub-opening (OPT2_S) overlapping with second sub-luminous regions (SEA2), and a third sub-opening (OPT3_S) overlapping with third sub-luminous regions (SEA3).

[0177] Each of the plurality of sub-openings (OPT_S) may have a planar area larger than the planar area of ​​each sub-luminous region (SEA). For example, the first sub-opening (OPT1_S) may have a planar area larger than the first sub-luminous region (SEA1), the second sub-opening (OPT2_S) may have a planar area larger than the second sub-luminous region (SEA2), and the third sub-opening (OPT3_S) may have a planar area larger than the third sub-luminous region (SEA3).

[0178] An opening corresponding to a transmission area (TA) can be defined by a light-blocking layer (BM). The opening corresponding to the transmission area (TA) can be arranged in a first direction (DR1).

[0179] A plurality of sub-color sections (CF_S) may each be arranged corresponding to a plurality of sub-emission regions (SEA). For example, a first sub-color section (CF1_S) may be placed overlappingly in a first sub-emission region (SEA1), a second sub-color section (CF2_S) may be placed overlappingly in a second sub-emission region (SEA2), and a third sub-color section (CF3_S) may be placed overlappingly in a third sub-emission region (SEA3).

[0180] Each of the plurality of sub-color sections (CF_S) may have a different size or area on a plane. As described above, the size or area of ​​each of the plurality of sub-luminous regions (SEA) may differ, and accordingly, the size or area of ​​the plurality of sub-color sections (CF_S) on a plane may also differ. For example, the size or area of ​​the third sub-color section (CF3_S) may be larger than the size or area of ​​the first sub-color section (CF1_S) and the second sub-color section (CF2_S). Additionally, the size or area of ​​the first sub-color section (CF1_S) may be larger than the size or area of ​​the second sub-color section (CF2_S). The size of each of the plurality of sub-color sections (CF_S) may be closely related to the color tone of the sub-display region (SDA) due to external light reflection.

[0181] Each of the plurality of sub-color sections (CF_S) may have a planar area larger than the planar area of ​​each sub-emissive region (SEA). For example, the first sub-color section (CF1_S) may have a planar area larger than the first sub-emissive region (SEA1), the second sub-color section (CF2_S) may have a planar area larger than the second sub-emissive region (SEA2), and the third sub-color section (CF3_S) may have a planar area larger than the third sub-emissive region (SEA3).

[0182] A plurality of sub-color sections (CF_S) may each be arranged corresponding to a plurality of sub-openings (OPT_S) of the light-blocking layer (BM). For example, a first sub-color section (CF1_S) may be superimposed on a first sub-opening (OPT1_S) of the light-blocking layer (BM), a second sub-color section (CF2_S) may be superimposed on a second sub-opening (OPT2_S) of the light-blocking layer (BM), and a third sub-color section (CF3_S) may be superimposed on a third sub-opening (OPT3_S) of the light-blocking layer (BM).

[0183] Each of the plurality of sub-color sections (CF_S) may have a planar area larger than the planar area of ​​each of the sub-openings (OPT_S) of the shading layer (BM). For example, the first sub-color section (CF1_S) may have a planar area larger than the first sub-opening (OPT1_S) of the shading layer (BM), the second sub-color section (CF2_S) may have a planar area larger than the second sub-opening (OPT2_S) of the shading layer (BM), and the third sub-color section (CF3_S) may have a planar area larger than the third sub-opening (OPT3_S) of the shading layer (BM). Accordingly, each of the plurality of sub-color sections (CF_S) can completely cover the sub-openings (OPT_S) of the shading layer (BM).

[0184] In the drawing, the planar shape of each of the sub-color parts (CF_S) is depicted as being approximately rectangular, but is not limited thereto.

[0185] In a display device according to the embodiments of the present specification, the structure of a main display pixel and a light-blocking layer disposed in a main display area and the structure of a sub display pixel and a light-blocking layer disposed in a sub display area can be formed to be substantially identical to each other.

[0186] Referring to FIGS. 13 and 14, the display layer (DU) and the touch sensing layer (TSU) have been described above, so most of the repetitive descriptions thereof are omitted.

[0187] The first pixel defining film (PDL1) may be a pixel defining film that defines a plurality of light-emitting regions included in the main light-emitting region (MEA) and the sub-light-emitting region (SEA).

[0188] The first spacers (SPC1_S, SPC2_S, SPC3_S) placed in the sub-display area (SDA) may be placed on the first pixel definition film (PDL1). The first spacers (SPC1_S, SPC2_S, SPC3_S) may be spacers placed on the first pixel definition film (PDL1) which defines a plurality of light-emitting areas included in the main light-emitting area (MEA) and the sub-light-emitting area (SEA).

[0189] The first spacer (SPC1_S, SPC2_S, SPC3_S) can serve to support the mask during the process of manufacturing the light-emitting layer (EL). The first spacer (SPC1_S, SPC2_S, SPC3_S) 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.

[0190] The light-emitting element (ED) may include pixel electrodes (AE1, AE2, AE3), a light-emitting layer (EL), and a first common electrode (CE1). The first common electrode (CE1) may be a common electrode disposed in a plurality of light-emitting regions included in a main light-emitting region (MEA) and a sub-light-emitting region (SEA). Accordingly, the first common electrode (CE1) may be disposed on a first pixel defining film (PDL1) and a first spacer (SPC1_S, SPC2_S, SPC3_S).

[0191] The color filter layer (CFL) may include a light-blocking layer (BM), a sub-color section (CF_S), and an overcoat layer (OC).

[0192] The light-blocking layer (BM) may include a plurality of sub-openings (OPT_S) that are overlapped with sub-luminous regions (SEA). For example, a first sub-opening (OPT1_S) may overlap with a first sub-luminous region (SEA1) in a third direction (DR3), a second sub-opening (OPT2_S) may overlap with a second sub-luminous region (SEA2) in a third direction (DR3), and a third sub-opening (OPT3_S) may overlap with a third sub-luminous region (SEA3) in a third direction (DR3).

[0193] The area or size of each sub-aperture (OPT_S) may be larger than the area or size of the sub-emissive region (SEA). Additionally, the area or size of each sub-aperture (OPT_S) may be formed to be larger than the openings of the first pixel defining film (PDL1), and the light emitted from the light-emitting element (ED) may be visible to the user not only from the front but also from the side of the display device (10).

[0194] The sub-color section (CF_S) of the color filter layer (CFL) may include the first sub-color section (CF1_S) of the first color filter layer (CFL1), the second sub-color section (CF2_S) of the second color filter layer (CFL2), and the third sub-color section (CF3_S) of the third color filter layer (CFL3).

[0195] Sub-color sections (CF_S) can each be arranged corresponding to sub-emission regions (SEA). For example, a first sub-color section (CF1_S) can be arranged overlappingly with a first sub-emission region (SEA1) in a third direction (DR3), a second sub-color section (CF2_S) can be arranged overlappingly with a second sub-emission region (SEA2) in a third direction (DR3), and a third sub-color section (CF3_S) can be arranged overlappingly with a third sub-emission region (SEA3) in a third direction (DR3).

[0196] Sub-color sections (CF_S) can each be arranged to correspond to sub-openings (OPT_S) of the light-blocking layer (BM). For example, the first sub-color section (CF1_S) can cover the first sub-opening (OPT1_S), the second sub-color section (CF2_S) can cover the second sub-opening (OPT2_S), and the third sub-color section (CF3_S) can cover the third sub-opening (OPT3_S).

[0197] The widths of the sub-color sections (CF_S) may be larger than the widths of the sub-openings (OPT_S) of the shading layer (BM). For example, the width of the first sub-color section (CF1_S) may be larger than the width of the first sub-opening (OPT1_S) of the shading layer (BM), the width of the second sub-color section (CF2_S) may be larger than the width of the second sub-opening (OPT2_S) of the shading layer (BM), and the width of the third sub-color section (CF3_S) may be larger than the width of the third sub-opening (OPT3_S) of the shading layer (BM).

[0198] Referring to FIG. 14, a transparent area (TA) may be defined by a light-blocking layer (BM). The light-blocking layer (BM) may include an opening that defines the transparent area (TA). The transparent area (TA) may be defined as the area between the side of one light-blocking layer (BM) and the side of another light-blocking layer (BM).

[0199] The embodiment may include a pixel defining film (PDL1, PDL2) comprising a first pixel defining film (PDL1) and a second pixel defining film (PDL2), a spacer (SPC1_S, SPC2) comprising a first spacer (SPC1_S) and a second spacer (SPC2), and a common electrode (CE1, CE2) comprising a first common electrode (CE1) and a second common electrode (CE2). As illustrated, at one boundary of a transmission region (TA), the first spacer (SPC1_S) and the second spacer (SPC2), the first pixel defining film (PDL1) and the second pixel defining film (PDL2), and the first common electrode (CE1) and the second common electrode (CE2) may be physically connected to each other. The second pixel defining layer (PDL2) may include the same material as the first pixel defining layer (PDL1), the second spacer (SPC2) may include the same material as the first spacer (SPC1_S), and the second common electrode (CE2) may include the same material as the first common electrode (CE1).

[0200] A common electrode (CE1, CE2) comprising a first common electrode (CE1) and a second common electrode (CE2) can be formed from a material with high transmittance in a front-facing light emission method. For example, the common electrode (CE1, CE2) 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 (CE1, CE2) is formed from a semi-transmissive conductive material, the light emission efficiency can be increased by microcavities.

[0201] Since an optical device is placed in the sub-display area, it is necessary to form a path for light to travel. Therefore, a separate transparent area (TA) may be placed in the sub-display area. At the same time, all metal wiring placed in the transparent area (TA) can be formed of a transparent material so that light can pass through the transparent area (TA). For example, the common electrodes (CE1, CE2) need to be formed of a transparent conductive material.

[0202] However, even if a transparent material is used, the intensity of light passing through the metal may be weakened, and if the second common electrode (CE2) is placed over the entire transmission area (TA), the transmittance and / or pass rate of light may be reduced.

[0203] A display device according to an embodiment of the present specification divides a transparent region (TA) into a second transparent region (TA2) including a second common electrode (CE2) and a first transparent region (TA1) including an alternative pattern (RPT). The alternative pattern (RPT) may be placed on the same layer as the second common electrode (CE2). For example, both the second common electrode (CE2) and the alternative pattern (RPT) may be placed on a second spacer (SPC2).

[0204] In other words, the replacement pattern (RPT) may be a pattern formed during the process of removing the common electrodes (CE1, CE2) to improve light transmittance, etc. The common electrodes (CE1, CE2) may be formed commonly across the entire display area, including the main display area and the sub-display area. When the common electrodes (CE1, CE2) are deposited after forming the replacement pattern (RPT) on at least a portion of the transmission area (TA), the second common electrode (CE2) is not placed in the first transmission area (TA1), and light transmittance, etc. can be improved through this replacement pattern (RPT). The replacement pattern (RPT) performs the function of suppressing the formation of a metal film, thereby improving the transmittance characteristics of the transmission area (TA). The common electrodes (CE1, CE2), including the first common electrode (CE1) and the second common electrode (CE2), may be selectively deposited by the replacement pattern (RPT).

[0205] In one embodiment, the common electrode (CE1, CE2) may be formed of an alloy of magnesium (Mg) and silver (Ag). The alternate pattern (RPT) may include a carbonaceous material. Alternatively, the alternate pattern (RPT) may be a compound including a carbonaceous material and a fluorine-based material.

[0206] In another embodiment, the alternative pattern (RPT) may include an aromatic hydrocarbon comprising a carbonaceous material. Alternatively, the alternative pattern (RPT) may include a deuterated aromatic hydrocarbon.

[0207] However, as described above, the replacement pattern (RPT) needs to maintain a certain distance from the first sub-emissive region, the second sub-emissive region, and the third sub-emissive region. This prevents the problem of shrinkage of the emission region caused by gas generated during the manufacturing process.

[0208] Returning to the point, the replacement pattern (RPT) may be a material that is placed to replace the common electrodes (CE1, CE2) to improve characteristics such as transmittance. Accordingly, the replacement pattern (RPT) placed in the first transmission region (TA1) may be placed in the same layer as the second common electrode (CE2) or the first common electrode (CE1).

[0209] The first transmission region (TA1) may be defined by an alternative pattern (RPT). For example, the first transmission region (TA1) may be defined by the boundary or side of the alternative pattern (RPT). A boundary between the alternative pattern (RPT) and the second common electrode (CE2) may be formed at the boundary between the first transmission region (TA1) and the second transmission region (TA2).

[0210] Additionally, the second spacer (SPC2) may be disposed in the first transparent region (TA1) while the second pixel defining film (PDL2) is not disposed therein. The first transparent region (TA1) may overlap with the aperture region (OPA), defined as the area between one end of the second pixel defining film (PDL2), in the third direction (DR3). The second spacer (SPC2) may be disposed in the first transparent region (TA1). Furthermore, the second spacer (SPC2) may also be disposed in the second transparent region (TA2). A detailed description regarding the structure will be provided later.

[0211] The embodiment may additionally include a first transmission region (TA1) in which an alternative pattern (RPT) is disposed to improve transmittance, etc. Additionally, the transmission region (TA) may further include a second transmission region (TA2) in which a second common electrode (CE2) containing a metal material is disposed.

[0212] However, in the case where a first transmission region (TA1) is disposed in which common electrodes (CE1, CE2) are not formed, the first transmission region (TA1) can be easily identified when compared with the second transmission region (TA2), sub-luminous region, and main-luminous region in which common electrodes (CE1, CE2) are disposed. Since the second common electrode (CE2) disposed in the second transmission region (TA2) contains the same material as the first common electrode (CE1) disposed in the sub-luminous region and the main-luminous region, all of these are simplified, and only the phase difference of the second transmission region (TA2) and the phase difference of the first transmission region (TA1) are considered.

[0213] The first transmission area (TA1) may have a first phase difference, and the second transmission area (TA2) may have a second phase difference. A relatively large difference between the first phase difference and the second phase difference means that the first transmission area (TA1) is relatively easily visible from the display device, and therefore, the display quality of the display device can be seen as degraded.

[0214] The display device according to the embodiment of the present specification can achieve improved transmittance characteristics by placing an alternative pattern (RPT) and, at the same time, reduce the gap between the first phase difference and the second phase difference by placing a second spacer (SPC2) in the aperture area (OPA) defined by the second pixel defining film (PDL2). Therefore, there is an advantage in that the transmittance characteristics of the sub-display area can be improved while ensuring the display quality of the display device.

[0215] FIG. 15 is a partial enlarged view showing the K region of FIG. 14 in enlargement. FIG. 15 is also a cross-sectional view showing an embodiment of the present specification.

[0216] Referring to FIG. 15, a second pixel defining film (PDL2) may be disposed on the second protective layer (PAS2) (or, protective layer (PAS)). The second pixel defining film (PDL2) may be disposed in the second transparent region (TA2). An aperture region (OPA) may be defined by the side surface (PDL2S) of the second pixel defining film (PDL2) and the top surface (PASU) of the protective layer (PAS). In other words, the second pixel defining film (PDL2) may include an aperture region (OPA).

[0217] The second spacer (SPC2) may include the same material as the first spacer (SPC1_S). In the second transparent region (TA2), the second spacer (SPC2) may be placed on the second pixel defining film (PDL2). The second spacer (SPC2) placed in the second transparent region (TA2) may be physically connected to the second spacer (SPC2) placed in the first transparent region (TA1). The second spacer (SPC2) placed in the first transparent region (TA1) may also be placed in the aperture region (OPA) defined by the second pixel defining film (PDL2).

[0218] The alternative pattern (RPT) placed in the first transmission region (TA1) and the second common electrode (CE2) placed in the second transmission region (TA2) can both be placed on the same layer. For example, they can both be placed on the second spacer (SPC2).

[0219] In one embodiment, the second spacer (SPC2) may include the same material as the second protective layer (PAS2) (or protective layer (PAS)). Accordingly, the second protective layer (PAS2) (or protective layer (PAS)) may include the same material as the first spacer (SPC1_S).

[0220] Encapsulation layers (TFE1, TFE2) may be disposed on the second common electrode (CE2) and the alternate pattern (RPT). The encapsulation layers (TFE1, TFE2) may include a first encapsulation layer (TFE1) and a second encapsulation layer (TFE2) disposed on the first encapsulation layer (TFE1). The first encapsulation layer (TFE1) may include an inorganic insulating material, and the second encapsulation layer (TFE2) may include a polymer-based material. For example, the second encapsulation layer (TFE2) may be an organic encapsulation layer and the first encapsulation layer (TFE1) may be an inorganic encapsulation layer.

[0221] According to the display device of the embodiment, the dielectric constant of the second encapsulation layer (TFE2) may be relatively low. Despite the second encapsulation layer (TFE2) having a relatively low dielectric constant, the embodiment can improve the display quality of the display device by reducing the difference between the first phase difference and the second phase difference.

[0222] The opening region (OPA) may overlap with the second permeable region (TA2) and the third direction (DR3). The second spacer (SPC2) may be positioned to fill the opening region (OPA). The second spacer (SPC2) may contain the same material as the protective layer (PAS).

[0223] In one embodiment, a first height (H1) may be defined in a first transmission area (TA1) and a second height (H2) may be defined in a second transmission area (TA2). The first height (H1) may be a third direction (DR3) distance from the upper surface (PASU) of the protective layer (PAS) to the upper surface (SPC2U) of the second spacer (SPC2). The second height (H2) may be a third direction (DR3) distance from the upper surface (PASU) of the protective layer (PAS) to the upper surface (SPC2U) of the second spacer (SPC2). The first height (H1) and the second height (H2) may be substantially the same. The second pixel defining film (PDL2) may be disposed on the upper surface (PASU) of the protective layer (PAS) in the second transmission area (TA2).

[0224] A second spacer (SPC2) disposed in a first transmission area (TA1) may have a first thickness (TH1), and a second spacer (SPC2) disposed in a second transmission area (TA2) may have a second thickness (TH2). The first thickness (TH1) may be a third direction (DR3) distance from the upper surface (PASU) of the protective layer (PAS) to the upper surface (SPC2U) of the second spacer (SPC2). The second thickness (TH2) may be a third direction (DR3) distance from the upper surface (PDL2U) of the second pixel defining film (PDL2) to the upper surface (SPC2U) of the second spacer (SPC2). In one embodiment, the first thickness (TH1) and the second thickness (TH2) may be different. For example, the difference between the first thickness (TH1) and the second thickness (TH2) may be substantially the same as the thickness of the second pixel definition film (PDL2).

[0225] Since the replacement pattern (RPT) is placed in the first transmission region (TA1) instead of the second common electrode (CE2) to improve transmittance characteristics, etc., other physical properties, excluding the forming material, may be substantially the same as those of the second common electrode (CE2). Accordingly, the thickness of the replacement pattern (RPT) and the thickness of the second common electrode (CE2) may both be the same as the third thickness (TH3).

[0226] FIG. 16 is a cross-sectional view showing a first comparative example. FIG. 17 is a cross-sectional view showing a second comparative example. FIG. 18 is a diagram for explaining the comparison of the amount of phase change between a first transmission region and a second transmission region.

[0227] In the first comparative example, the second pixel defining film (PDL2) does not define a separate aperture region (OPA), and therefore the shape in which the second spacer (SPC2) is filled is also different from the above-described embodiment.

[0228] The second comparative example shows that the second spacer (SPC2) is not placed in the opening region (OPA), and after removing all second spacers (SPC2) corresponding to the first permeable region (TA1), a replacement pattern (RPT) is placed on the upper surface (PASU) of the protective layer (PAS). It differs from the above-described embodiment in that the first encapsulation layer (TFE1) is formed in the opening region (OPA), and the second encapsulation layer (TFE2) is placed to fill the opening region (OPA).

[0229] Referring to FIG. 18, the shape and arrangement structure of the second transmission region (TA2) in the above-described embodiment, the first comparative example, and the second comparative example are all identical. Therefore, the second phase difference of the second transmission region (TA2) has a constant value.

[0230] The first phase difference (TA1_1) of the embodiment is plotted on a graph having a second phase difference and a first phase change amount (PD1). The first phase difference (TA1_2) of the first comparative example is plotted on a graph having a second phase difference and a second phase change amount (PD2). The first phase difference (TA1_3) of the second comparative example is plotted having a second phase difference and a third phase change amount (PD3).

[0231] Referring to this, it is confirmed that the first phase change amount (PD1) is the smallest and the third phase change amount (PD3) is the largest. As described above, the larger the phase change amount corresponding to the difference between the first phase difference and the second phase difference, the relatively higher the probability that the first transmission area (TA1) will be visible on the display device.

An electronic device according to one embodiment includes the display device described above and may further include a module or device having additional functions other than the display device.
