[0036] Figure 1 is a perspective view schematically showing a display device 1 according to the embodiment.

[0037] Reference Figure 1 , the display device 1 may include a display area DA (i.e., an area from which light is emitted) and a non-display area NDA (i.e., an area from which light is not emitted). The display device 1 may provide (e.g., display) an image via the display area DA.

[0038] like Figure 1As shown in FIG. 1 , the display device 1 includes a first region R1 and a second region R2. The first region R1 and the second region R2 are locations where electronic components (described in more detail below) may be arranged. The first region R1 and the second region R2 may be understood as transmission regions through which light and / or sound output from the electronic components to the outside or traveling from the outside to the electronic components may pass. Figure 1 , two transmission regions (i.e., the first region R1 and the second region R2) are shown, but the present disclosure is not limited thereto, and three or more transmission regions may also be included. According to an embodiment, when light passes through the first region R1 and the second region R2, the transmittance of the first region R1 and the second region R2 may be about 50% or more, for example, about 70% or more, about 75% or more, about 80% or more, or about 85% or more.

The first non-display area NDA1 may, for example, continuously surround the combined first and second areas R1 and R2 (e.g., the entire periphery of the combined first and second areas R1 and R2), the display area DA may, for example, continuously surround the first non-display area NDA1 as a whole (e.g., the entire periphery of the first non-display area NDA1), and the second non-display area NDA2 may surround the display area DA as a whole (e.g., the entire periphery of the display area DA).

[0040] FIG. 2A to FIG. 2C is along Figure 1 A cross-sectional view taken along line II-II'.

[0041] Reference Figure 2A The display device 1 may include a display panel 10, and the display panel 10 includes, for example Figure 4 The display panel 10 includes a display element of a pixel P in the pixel P and a first electronic element 20 and a second electronic element 30 corresponding to the first region R1 and the second region R2, respectively. Although not shown in the drawings, elements such as an input sensing member for sensing a touch input, an anti-reflection member including a polarizer and a retarder or a color filter and a black matrix, and a transparent window may be further arranged on the display panel 10.

[0042] The display panel 10 may include a substrate 100 , an encapsulation substrate 300A as an encapsulation member facing the substrate 100 , and a sealing member 350 between the substrate 100 and the encapsulation substrate 300A.

[0043] The substrate 100 may include, for example, glass or a polymer resin. The polymer resin may be, for example, polyethersulfone (PES), polyarylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyimide (PI), polycarbonate (PC), cellulose acetate propionate (CAP), etc. The substrate 100 including the polymer resin may be flexible, rollable, or bendable. The substrate 100 may have a multilayer structure including a layer including the above-mentioned polymer resin and an inorganic layer. The encapsulation substrate 300A may include, for example, glass or the above-mentioned polymer resin.

[0044] The thin film transistor TFT and the organic light emitting diode OLED connected to the thin film transistor TFT as a display element may be arranged in the display area DA of the substrate 100. The signal line SGL is arranged in the first non-display area NDA1 of the substrate 100. Predetermined signals such as data signals, scan signals, etc. may be provided to the display elements spaced apart from each other in the direction in which the signal line SGL extends with respect to the first and second regions R1 and R2 via the signal line SGL.

[0045] The display panel 10 may include through holes corresponding to (e.g., overlapping) the first and second regions R1 and R2, respectively. For example, the substrate 100 and the encapsulation substrate 300A may include through holes 100H and 300AH corresponding to (e.g., overlapping) the first and second regions R1 and R2, respectively, and the insulating layer IL or element between the substrate 100 and the encapsulation substrate 300A and corresponding to (e.g., overlapping) the first and second regions R1 and R2 may also be completely removed. Figure 2A The sealing member 350 disposed on both sides of the first and second regions R1 and R2 is shown, but when viewed in a direction perpendicular to the main surface of the substrate 100 , the first and second regions R1 and R2 may be respectively considered to be completely surrounded by the sealing member 350 .

[0046] The first electronic component 20 and the second electronic component 30 may be located in the first region R1 and the second region R2, respectively. The first electronic component 20 and the second electronic component 30 may be electronic components that use light or sound. For example, the electronic component may be a sensor (e.g., an infrared sensor) used by receiving light, a camera that receives light to capture an image, a sensor that measures a distance or senses a fingerprint by outputting or sensing light or sound, a compact lamp that outputs light, a speaker that outputs sound, etc. Electronic components that use light may use light of various bands, such as visible light, infrared light, and ultraviolet light.

[0047] When the display panel 10 is Figure 2AWhen the through holes corresponding to the first and second regions R1 and R2 are included as shown in FIG, light or sound output through the first and second electronic components 20 and 30 or received through the first and second electronic components 20 and 30 may be effectively used.

[0048] and Figure 2A Unlike the display panel 10 having through holes corresponding to the first region R1 and the second region R2, some elements of the display panel 10 may not include through holes. Figure 2B As shown in , the package substrate 300A may include a through hole 300AH corresponding to each of the first region R1 and the second region R2, for example, while the substrate 100 may not have a through hole. Figure 2C As shown in FIG. 1 , the substrate 100 and the package substrate 300A may not include through holes corresponding to the first region R1 and the second region R2. Figure 2B and Figure 2C When the through hole 100H is not included as shown in FIG, the light transmittance for the first electronic component 20 and the second electronic component 30 can also be ensured by removing the insulating layer IL or the element corresponding to the first region R1 and the second region R2 between the substrate 100 and the encapsulation substrate 300A. Figure 2B and Figure 2C In the display panel 10 shown in FIG. 1 , electronic components using light may be used as the first electronic component 20 and the second electronic component 30 .

[0049] FIG. 3A to FIG. 3C is a cross-sectional view schematically showing a display device 1' according to other embodiments, and can be compared with the Figure 1 The cross section corresponds to the line II-II'.

[0050] Reference Figure 3A , and refer to the above Figure 2A Like the display device 1 described above, the display device 1' may include a display panel 10', the display panel 10' includes a display element and a first electronic component 20 and a second electronic component 30 corresponding to the first region R1 and the second region R2 of the display panel 10', respectively. In addition, the display device 1' may further include an input sensing member for sensing a touch input, an anti-reflection member, a window, etc. on the display panel 10'.

[0051] The display panel 10' according to the present embodiment may include a thin film encapsulation layer 300B, which may further enhance the flexibility of the display panel 10'. For example, the thin film encapsulation layer 300B of the display panel 10' may be thinner than FIG. 2A to FIG. 2C The encapsulation substrate 300A of the display panel 10 in FIG. 1 is thin and flexible. Hereinafter, for the convenience of description, the description will focus on the differences.

[0052] The thin film encapsulation layer 300B may include at least one inorganic encapsulation layer and at least one organic encapsulation layer. Figure 3A A first inorganic encapsulating layer 310 and a second inorganic encapsulating layer 330 and an organic encapsulating layer 320 located between the first inorganic encapsulating layer 310 and the second inorganic encapsulating layer 330 are further illustrated.

[0053] The first inorganic encapsulation layer 310 and the second inorganic encapsulation layer 330 may include at least one inorganic insulating material, such as aluminum oxide, titanium oxide, tantalum oxide, hafnium oxide, zinc oxide, silicon oxide, silicon nitride, and silicon oxynitride. The organic encapsulation layer 320 may include a polymer material, such as acrylic resin, epoxy resin, PI, and polyethylene.

[0054] The display panel 10' may include through holes corresponding to (e.g., overlapping) the first and second regions R1 and R2. For example, the substrate 100 and the thin film encapsulation layer 300B may include through holes 100H and 300BH corresponding to the first and second regions R1 and R2, respectively. As described above, the first and second electronic components 20 and 30 using light or sound may also be arranged in the first and second regions R1 and R2.

[0055] Reference Figure 3B ,and Figure 3A Unlike the display panel 10' having through holes in the substrate 100 corresponding to the first and second regions R1 and R2, the thin film encapsulation layer 300B may include through holes 300BH corresponding to the first and second regions R1 and R2, while the substrate 100 may not have through holes. Figure 3C As shown in , the substrate 100 and the thin film encapsulation layer 300B may not include the through holes corresponding to the first and second regions R1 and R2. Even when the substrate 100 does not include the through holes 100H, the light transmittance for the first and second electronic components 20 and 30 can be ensured by removing the insulating layer IL or the element corresponding to the first and second regions R1 and R2 between the substrate 100 and the thin film encapsulation layer 300B.

[0056] When the thin film encapsulation layer 300B includes Figure 3A and Figure 3B When the through hole 300BH is shown in FIG. 3 , each of the at least one inorganic encapsulation layer and the at least one organic encapsulation layer may include a hole corresponding to the through hole 300BH. The hole of the organic encapsulation layer may be larger than the hole of the at least one inorganic encapsulation layer, so that the first inorganic encapsulation layer 310 and the second inorganic encapsulation layer 330 may directly contact each other around the first region R1 and the second region R2.

[0057] When the thin film encapsulation layer 300B does not include a through hole, such as Figure 3CAs shown in FIG. 1 , each of at least one inorganic encapsulation layer and at least one organic encapsulation layer may cover the first region R1 and the second region R2. In this case, a portion of the insulating layer IL between the substrate 100 and the thin film encapsulation layer 300B may be removed. Figure 3A It is shown that the insulating layer IL corresponding to the first region R1 and the second region R2 is completely removed, but only some layers of the insulating layer IL of the plurality of layers may be removed.

[0058] Figure 4 is a plan view schematically showing a display panel 10 according to an embodiment, Figure 5 Schematically shows an equivalent circuit diagram of a pixel of the display panel 10 .

[0059] Reference Figure 4 , the display panel 10 may include a plurality of pixels P arranged in a display area DA. Each pixel P may include a display element such as an organic light emitting diode OLED. The pixel P may emit red light, green light, blue light, or white light through the organic light emitting diode OLED. In this specification, the pixel P may be understood as a pixel that emits light of any one of the colors of red, green, blue, and white as described above. The display area DA may be referred to above Figures 2A to 3C The described packaging structure covers and is protected from external air or moisture.

[0060] Reference Figure 5 , each pixel P includes a pixel circuit PC and an organic light emitting diode OLED connected to the pixel circuit PC. The pixel circuit PC may include a first thin film transistor T1, a second thin film transistor T2, and a storage capacitor Cst.

[0061] The second thin film transistor T2 is a switching thin film transistor and is connected to the scan line SL and the data line DL, and transmits a data voltage input through the data line DL to the first thin film transistor T1 according to a switching voltage input through the scan line SL. The storage capacitor Cst is connected to the second thin film transistor T2 and the driving voltage line PL, and stores a voltage corresponding to a difference between a voltage received from the second thin film transistor T2 and a first power supply voltage ELVDD supplied to the driving voltage line PL.

[0062] The first thin film transistor T1 is a driving thin film transistor and is connected to the driving voltage line PL and the storage capacitor Cst, and can control the driving current flowing from the driving voltage line PL through the organic light emitting diode OLED according to the voltage value stored in the storage capacitor Cst. The organic light emitting diode OLED can emit light with a predetermined brightness via the driving current. The counter electrode (e.g., cathode) of the organic light emitting diode OLED can receive the second power supply voltage ELVSS.

[0063] Figure 5 The pixel circuit PC is shown to include two thin film transistors and one storage capacitor, but the present disclosure is not limited thereto. For example, the number of thin film transistors and the number of storage capacitors may be different depending on the design of the pixel circuit PC.

[0064] Refer again Figure 4 , the first non-display area NDA1 surrounds both the first area R1 and the second area R2. For example, the first non-display area NDA1 may be located between the display area DA and the first area R1 and the second area R2 (ie, between the display area DA and the first area R1 and the second area R2). Figure 4 The first non-display area NDA1 corresponds to an area through which signal lines pass, and signals are provided to pixels P included around the first non-display area NDA1 via the signal lines. For example, the first non-display area NDA1 accommodates signal lines connected to the pixels P in the display area DA surrounding the first non-display area NDA1.

[0065] The second non-display area NDA2 may include a scan driver 1000 supplying a scan signal to each pixel P, a data driver 2000 supplying a data signal to each pixel P, a main power wiring through which a first power voltage ELVDD and a second power voltage ELVSS are supplied, and the like.

[0066] Figure 4 It can be understood as a substrate 100 included in the display panel 10. For example, the substrate 100 includes a first region R1 and a second region R2, a display area DA, and a first non-display area NDA1 and a second non-display area NDA2. Similarly, for example, Figure 2A The signal line SGL may be understood to be arranged in the first non-display area NDA1 to be connected to the reference Figure 4 Described is the signal line of the pixel P.

[0067] Figure 6 is a plan view showing a portion of the display panel 10 according to the embodiment, and Figure 4 corresponds to an enlarged view of region VI. Figure 7 yes Figure 6 Selected plan views of some signal lines.

[0068] Reference Figure 6 to Figure 7 , the first region R1 and the second region R2 may be arranged in a first direction, for example, adjacent to each other in the x direction, and the signal line may extend in a second direction intersecting the first direction, for example, the signal line may extend in the y direction. In this regard, Figure 6 It is shown that the first region R1 and the second region R2 are arranged in the x direction, and the data lines DLa, DLb, and DLc extend in the y direction as signal lines.

[0069] Some of the data lines DLa and DLb may extend in the y direction so that signals are provided to pixels located above and below the first non-display area NDA1 relative to the XY plane, and may detour (e.g., detour) along the edge of the first area R1 or the second area R2 in the first non-display area NDA1. Other data lines DLc do not cross the first non-display area NDA1, and may extend substantially in a straight line in the display area DA. The data lines DLa and DLb have a predetermined pitch Δp in the display area DA, and have a pitch Δd (Δp>Δd) smaller than the above-mentioned pitch Δp in the first non-display area NDA1.

[0070] Hereinafter, for the convenience of description, the data lines DLa crossing the first non-display area NDA1 in the area between the first area R1 and the second area R2 (i.e., the first sub non-display area SBR1) will be referred to as the first group, and the data lines DLb crossing the first non-display area NDA1 outside the first sub non-display area SBR1 will be referred to as the second group. The data lines DLb of the second group pass in the area between the first edge of the first non-display area NDA1 and the edge of the first area R1 and the area between the second edge of the first non-display area NDA1 and the edge of the second area R2 (i.e., the second sub-display area SBR2).

[0071] When referring to Figure 6 When the area around the first region R1 shown in FIG. 1 is shown, some data lines DLa of the first group are along a first side of the first region R1 (eg, Figure 6 Some data lines DLb of the second group detour along the second side of the first region R1 (eg, Figure 6 The first group of data lines DLa around the first region R1 and the second group of data lines DLb around the first region R1 detour in opposite directions at the first point CP1. The first point CP1 is not located on the first virtual line CL1 that passes through the first center C1 of the first region R1 and extends in the y direction. The first point CP1 is offset relative to the first virtual line CL1 toward a side adjacent to the first edge of the first non-display area NDA1. For example, the first point CP1 may be along the first virtual line CL1 relative to the first virtual line CL1. Figure 6 The x direction in the image is offset horizontally to the left.

[0072] Reference Figure 6 , the first point CP1 may be located on the left side with respect to the first virtual line CL1. The first point CP1 is spaced apart from the first virtual line CL1 by a predetermined distance. Therefore, some of the data lines DLa and DLb detoured along the edge of the first region R1 have an asymmetric shape with respect to the first virtual line CL1.

[0073] For details, refer to Figure 7 , the adjacent first and second data lines DL1 and DL2 , which are adjacent to each other with respect to the first point CP1 , bypass the first region R1 in directions opposite to each other. Figure 7 The first data line DL1 is Figure 6 One of the data lines DLa of the first group shown in FIG. Figure 6 One data line of the second group of data lines DLb shown in FIG.

[0074] The first data line DL1 and the second data line DL2 are asymmetric with respect to the first virtual line CL1, and therefore, one of the length and the center angle of the first curved portion (meandering portion or detour portion) DL1-C of the first data line DL1 may be different from one of the length and the center angle of the second curved portion (meandering portion or detour portion) DL2-C of the second data line DL2. Figure 7 The length of the portion of the first region R1 that is bent (or detoured, circuitous) on the right side of the first region R1 in the embodiment of the present invention may be longer than the second winding portion DL2-C (eg, the portion along the second data line DL2). Figure 7 The length of the left side curved (or detoured, circuitous) portion of the first region R1 is large. Figure 6 and Figure 7 It is shown that each of the first meandering portion DL1-C and the second meandering portion DL2-C has an arc shape, for example, a smoothly curved shape based on an arc, but the present disclosure is not limited thereto. For example, each of the first meandering portion DL1-C and the second meandering portion DL2-C generally has an arc shape, but partially has a sawtooth shape or a stepped shape, etc. That is, each of the first meandering portion DL1-C and the second meandering portion DL2-C has a stepped shape based on an arc.

[0075] Therefore, the central angle α1 of the first meandering portion DL1-C may be greater than the central angle β1 of the second meandering portion DL2-C. Figure 7 As shown in FIG. 1 , the central angle α1 of the first meandering portion DL1 -C may be Figure 7 The angle between the dotted / dashed lines of the linear portion connected to the first data line DL1 on the opposite side of the first region R1 in FIG. 1 (ie, an angle greater than 180°), and the central angle β1 of the second meandering portion DL2-C may be Figure 7 An angle between dotted / dashed lines connected to the linear portion of the second data line DL2 on the opposite side of the first region R1 in FIG. 1 (ie, an angle less than 180°).

[0076] Similarly, when referring to Figure 6 When the area around the second region R2 shown in FIG. 1 is shown, some data lines DLa of the first group are along the first side of the second region R2 (eg, Figure 6 Some data lines DLb of the second group detour along the second side of the second region R2 (eg, Figure 6 The first group of data lines DLa around the second region R2 and the second group of data lines DLb around the second region R2 detour in opposite directions at the second point CP2. The second point CP2 is not located on the second virtual line CL2 extending in the y direction and passing through the second center C2 of the second region R2. The second point CP2 is offset relative to the second virtual line CL2 toward a side adjacent to the second edge of the first non-display area NDA1. For example, the second point CP2 may be along the second virtual line CL2 relative to the second virtual line CL2. Figure 6 The x direction in the image is offset horizontally to the right.

[0077] Reference Figure 6 , the second point CP2 is located on the right side relative to the second virtual line CL2. The second point CP2 is spaced apart from the second virtual line CL2 by a predetermined distance. Therefore, the data lines DLa and DLb detour along the edge of the second region R2 have an asymmetric shape relative to the second virtual line CL2.

[0078] For details, refer to Figure 7 , the third data line DL3 and the fourth data line DL4 adjacent to each other with respect to the second point CP2 detour in directions opposite to each other. Figure 7 The third data line DL3 is Figure 6 One of the data lines DLa of the first group shown in FIG. Figure 6 One data line of the second group of data lines DLb shown in FIG.

[0079] The third data line DL3 and the fourth data line DL4 are asymmetric with respect to the second virtual line CL2, and therefore, one of the length and the center angle of the third curved portion (meandering portion or detour portion) DL3-C of the third data line DL3 may be different from one of the length and the center angle of the fourth curved portion (meandering portion or detour portion) DL4-C of the fourth data line DL4. For example, the third meandering portion DL3-C (e.g., the length of the third data line DL3) may be different from the length of the third meandering portion DL3-C (e.g., the length of the third data line DL3). Figure 7 The length of the left curved portion of the second region R2 in the fourth data line DL4-C may be longer than that of the fourth meandering portion DL4-C (eg, the left curved portion of the fourth data line DL4). Figure 7 The length of the right curved portion of the second region R2 is large.

[0080] Therefore, the central angle α2 of the third meandering portion DL3-C may be greater than the central angle β2 of the fourth meandering portion DL4-C. Figure 7 As shown in FIG. , the central angle α2 of the third meandering portion DL3-C may be Figure 7The angle between the dotted / dashed lines of the linear portion connected to the third data line DL3 on the opposite side of the second region R2 in FIG. 1 is 0.0447° (ie, an angle greater than 180°), and the central angle β2 of the fourth meandering portion DL4-C may be Figure 7 An angle between dotted / dashed lines of the linear portion connected to the fourth data line DL4 on the opposite side of the second region R2 in FIG. 1 (ie, an angle less than 180°).

[0081] like Figure 6 and Figure 7 As shown in , because the first point CP1 and the second point CP2 are offset from the first virtual line CL1 and the second virtual line CL2 toward the edge of the first non-display area NDA1, respectively, relatively more data lines may be arranged in the first sub non-display area SBR1 between the first area R1 and the second area R2, and relatively fewer data lines may be arranged in the second sub non-display area SBR2. That is, the total number of the data lines DLa of the first group arranged in the first sub non-display area SBR1 may be greater than the total number of the data lines DLb of the second group arranged in the second sub non-display area SBR2.

[0082] Since the number of data lines DLb arranged in the second sub non-display region SBR2 can be reduced, the area of ​​the second sub non-display region SBR2 can also be reduced, for example, compared with the area of ​​the first sub non-display region SBR1. In this regard, Figure 6 It is shown that the first width W1 between the first region R1 and the second region R2 (e.g., along the x direction) is greater than the sum of the second width W2 between the first edge of the first non-display area NDA1 and the first region R1 and the third width W3 between the second edge of the first non-display area NDA1 and the second region R2 (W1>W2+W3). The first width W1 may be considered as the shortest width between the first region R1 and the second region R2, the second width W2 may be considered as the shortest width between the first edge of the first non-display area NDA1 and the first region R1, and the third width W3 may be considered as the shortest width between the second edge of the first non-display area NDA1 and the second region R2. The first width W1, the second width W2, and the third width W3 may be measured along a virtual line connecting the first center C1 and the second center C2.

[0083] Figure 8 is a schematic cross-sectional view illustrating data lines DLa and DLb arranged in the first non-display area NDA1 according to an embodiment. Figure 8 is along Figure 6 Cross-sections taken along lines VIIIa-VIIIa' and VIIIb-VIIIb'.

[0084] Reference Figure 8, the data lines DLa of the first group and the data lines DLb of the second group are arranged on the insulating layers, respectively. For example, a plurality of insulating layers 103, 105, 107, 109, and 113 may be stacked on the substrate 100, and the data lines DLa and DLb may be arranged on at least one of the insulating layers 103, 105, 107, and 109. The data lines DLa and DLb may be arranged on the same insulating layer, for example, on the first insulating layer 109, and may be covered by the second insulating layer 113. The insulating layers 103, 105, 107, 109, and 113 may include an inorganic insulating material, an organic insulating material, or a mixture of these materials, respectively.

[0085] The data lines DLa of the first group may be arranged to have a first interval Δd1, and the data lines DLb of the second group may be arranged to have a second interval Δd2. The first interval Δd1 and the second interval Δd2 may be the same or different.

[0086] Fig. 9 is a schematic cross-sectional view illustrating data lines DLa and DLb arranged in the first non-display area NDA1 according to another embodiment. Fig. 9 is along Figure 6 Sections along lines VIIIa-VIIIa' and VIIIb-VIIIb'.

[0087] Reference Fig. 9 , the data lines DLa of the first group and the data lines DLb of the second group are arranged on the insulating layer, respectively. The data lines DLa of the first group and the data lines DLb of the second group may be arranged alternately, and the interlayer insulating layer 111 is located between the data lines DLa of the first group arranged alternately and between the data lines DLb of the second group arranged alternately. For example, one data line DLa of the adjacent data lines DLa of the first group may be arranged under the interlayer insulating layer 111, and the other data line DLa may be arranged on the interlayer insulating layer 111. One data line DLb of the adjacent data lines DLb of the second group may be arranged under the interlayer insulating layer 111, and the other data line DLb may be arranged on the interlayer insulating layer 111. The interlayer insulating layer 111 may include an inorganic insulating material, an organic layer insulating material, or a mixture of these materials.

[0088] The first interval Δd1′ between the data lines DLa of the first group can be compared to the reference Figure 8 Similarly, the second interval Δd2′ between the data lines DLb of the second group may be smaller than the first interval Δd1 described in the reference. Figure 8 When the interval between adjacent data lines is reduced, the first non-display area NDA1 (refer to Figure 6 ) area. Fig. 9In the embodiment, the first distance Δd1 ′ and the second distance Δd2 ′ may be the same or different.

[0089] Fig.10 is a plan view showing a portion of a display panel according to another embodiment.

[0090] Reference Fig.10 , the difference is: Figure 6 The arrangement direction of the first region R1 and the second region R2 is described as being along the x direction, and Fig.10 The direction of arrangement of the first region R1 and the second region R2 shown in is the ob direction in an oblique direction with respect to the x direction.

[0091] For details, refer to Fig.10 , the data lines DLa of the first group and the data lines DLb of the second group extend in the y direction intersecting the ob direction (the arrangement direction of the first region R1 and the second region R2), and may detour in the first non-display area NDA1 along the edges of the first region R1 and the second region R2. The first data lines DL1 of the first group and the second data lines DL2 of the second group adjacent to each other relative to the first region R1 detour along the first side and the second side of the first region R1 at a first point CP1. Similarly, the third data lines DL3 of the first group and the fourth data lines DL4 of the second group adjacent to each other relative to the second region R2 detour along the first side and the second side of the second region R2 at a second point CP2. All other characteristics except that the first region R1 and the second region R2 are arranged in an oblique direction are the same as those described above with reference to FIG. Figures 6 to 9 Those descriptions provided are identical and therefore will not be repeated.

[0092] In reference Figures 1 to 10 In the described embodiments, the description focuses on two transmission regions (ie, the first region R1 and the second region R2 ) corresponding to electronic elements, but the present disclosure is not limited thereto.

[0093] Figures 11 to 14 is a plan view showing a portion of a display panel according to another embodiment. Figures 11 to 14 The described embodiments also include the above referenced Figures 1 to 10 The features described and those derived therefrom, therefore the following description will focus on the differences.

[0094] Reference Fig.11 , a third region R3 may be included between the first region R1 and the second region R2. The detailed cross-sectional structure of the third region R3 may be the same as that of the reference Figures 2A to 3CThe cross-sectional structures of the first region R1 and the second region R2 described are the same. When the display panel further includes a third region R3, some of the data lines DLa arranged between the first region R1 and the second region R2 detour (e.g., bypass) the third region R3, and may be symmetrical with each other relative to a third virtual line CL3 passing through the third center C3. At the same time, other data lines among the data lines DLa arranged between the first region R1 and the second region R2 may extend by detour (e.g., bypass) the first region R1 and the second region R2. The spacing (e.g., spacing between the detour portions) of the data lines arranged in the region between the first center C1 and the second center C2 may be larger than that of the reference region R3. Figure 6 The spacing between the data lines in the display area DA described is small (Δp>Δd, see Figure 6 ). In addition, also in Fig.11 In the embodiment shown in , the first point CP1 and the second point CP2 are also spaced apart from the first virtual line CL1 and the second virtual line CL2 , respectively, as described above.

[0095] Fig.11 It is shown that one third region R3 is arranged between the first region R1 and the second region R2, but the present disclosure is not limited thereto. According to another embodiment, a plurality of third regions R3 may be arranged between the first region R1 and the second region R2.

[0096] Fig.11 It is shown that the third region R3 is arranged directly between the first region R1 and the second region R2 in the x direction, but the present disclosure is not limited thereto. Fig.12 As shown in FIG. 1 , the third region R3 may be spaced apart from the first region R1 and the second region R2 by a predetermined distance in the y direction and arranged between the first region R1 and the second region R2 in the x direction.

[0097] Although Fig.12 A third region R3 is shown to be spaced apart from the first region R1 and the second region R2 in the y direction, but the present disclosure is not limited thereto. Fig.13 As shown in FIG. 1 , a plurality of third regions spaced apart from the first and second regions R1 and R2 in the y direction are arranged between the first and second regions R1 and R2. For ease of description, one of the plurality of third regions will be referred to as a third region R3, and another will be referred to as a fourth region R4.

[0098] Reference Fig.13 The third region R3 and the fourth region R4 are respectively spaced apart from the first region R1 and the second region R2 in the y direction and may be disposed between the first region R1 and the second region R2 in the x direction.

[0099] The data lines passing through the first non-display area NDA1 and adjacent to the third and fourth regions R3 and R4 may be arranged symmetrically with respect to the third and fourth virtual lines CL3 and CL4 passing through the third and fourth centers C3 and C4. The third and fourth virtual lines CL3 and CL4 may be arranged on the same line.

[0100] and Fig.13 Unlike the four transmissive regions (eg, the first region R1, the second region R2, the third region R3, and the fourth region R4, which are symmetrically arranged) included in the first non-display area NDA1, the regions within the first non-display area NDA1 may be asymmetrically arranged. Fig.14 , the four regions included in the display panel can be regarded as two pairs each including a first region R1 and a second region R2. For example, when a first region R1 and a second region R2 are grouped and named as a set, the second set can be arranged above the first set. Here, Fig.14 According to another embodiment, the arrangement relationship of the transmission areas may be modified in various ways, for example, so that the second set arranged above the first set is not offset but arranged parallel to the first set.

[0101] Although the above reference Figures 1 to 14 A display panel including two to four transmission areas is described, but the present disclosure is not limited thereto. According to another embodiment, five or more transmission areas may be included, and in this case, the arrangement of the data line relative to the two transmission areas (e.g., the first area R1 and the second area R2) and the characteristics of the first width to the third width are as described above.

[0102] Although the data lines crossing the first non-display area NDA1 have been described as signal lines in the above embodiments, the present disclosure is not limited thereto. As will be described below, the scan lines SLa and SLb may cross the first non-display area NDA1.

[0103] Fig.15 is a plan view showing a portion of a display panel according to another embodiment.

[0104] Reference Fig.15, the first region R1 and the second region R2 may be arranged in the y direction. The scan lines SLa, SLb, and SLc may extend in the x direction. Some of the scan lines SLa and SLb extend in the x direction to provide scan signals to pixels located on the left and right sides of the first region R1 and the second region R2 (e.g., the left and right sides of the first non-display area NDA1), and detour (e.g., detour) along the edges of the first region R1 and the second region R2 in the first non-display area NDA1. Other scan lines SLc may extend substantially in a straight line in the display area DA.

[0105] Hereinafter, from among the scan lines SLa and SLb crossing the first non-display area NDA1, those scan lines SLa crossing the first sub non-display area SBR1 between the first area R1 and the second area R2 will be referred to as a first group, and the other scan lines SLb will be referred to as a second group. The scan lines SLb of the second group pass through the second sub non-display area SBR2 between the edge of the first non-display area NDA1 and the edge of the first area R1 and the second sub non-display area SBR2 between the other edge of the first non-display area NDA1 and the edge of the second area R2.

[0106] When referring to Fig.15 When the area around the first region R1 shown in FIG. 1 is a region around the first region R1, some of the scan lines SLa of the first group are along a first side of the first region R1 (eg, Fig.15 Some scanning lines SLb of the second group go around the lower side of the first region R1 ( Fig.15 The first group of scanning lines SLa around the first region R1 and the second group of scanning lines SLb around the first region R1 detour in opposite directions at the first point CP1. The first point CP1 is offset from the first virtual line CL1 passing through the first center C1. For example, Fig.15 As shown in FIG. 1 , the first point CP1 may be located above the first virtual line CL1 to be adjacent to an edge of the first non-display area NDA1 .

[0107] The scan line detour along the edge of the first region R1 has an asymmetric shape with respect to the first virtual line CL1. The first scan line SL1 and the second scan line SL2 adjacent to each other detour in opposite directions at the first point CP1. The first scan line SL1 is one of the scan lines Sla of the first group, and the second scan line SL2 is one of the scan lines SLb of the second group.

[0108] The first scan line SL1 and the second scan line SL2 are asymmetric with respect to the first virtual line CL1, and therefore at least one of the length and the center angle of the first meandering portion of the first scan line SL1 may be different from at least one of the length and the center angle of the second meandering portion of the second scan line SL2.

[0109] Similarly, refer to Fig.15 In the area around the second region R2 shown in FIG. 1 , some of the scan lines SLa of the first group are along a first side of the second region R2 (eg, Fig.15 Some scanning lines SLb of the second group are arranged along the second side ( Fig.15 The first group of scanning lines SLa around the second region R2 and the second group of scanning lines SLb around the second region R2 detour in opposite directions at the second point CP2. The second point CP2 is offset from the second virtual line CL2 passing through the second center C2. For example, Fig.15 As shown in , the second point CP2 may be located below the second virtual line CL2 to be adjacent to the edge of the first non-display area NDA1.

[0110] The scan line detour along the edge of the second region R2 has an asymmetric shape with respect to the second virtual line CL2. The third scan line SL3 and the fourth scan line SL4 adjacent to each other detour in opposite directions at the second point CP2. The third scan line SL3 is one of the scan lines SLa of the first group, and the fourth scan line SL4 is one of the scan lines SLb of the second group.

[0111] The third scan line SL3 and the fourth scan line SL4 are asymmetric with respect to the second virtual line CL2, and therefore at least one of the length and the center angle of the third meandering portion of the third scan line SL3 may be different from at least one of the length and the center angle of the fourth meandering portion of the fourth scan line SL4.

[0112] Although the display panel Fig.15 The display panel is described as including two transmission areas and the scan lines meander around the transmission areas, but the present disclosure is not limited thereto. According to another embodiment, the display panel may include three or more transmission areas, and the characteristics of the arrangement of the scan lines will be apparent accordingly, as can be seen from the above reference. Figures 1 to 14 The description provided and the embodiments derived therefrom are derived.

[0113] By way of summary and review, as a method of extending functions to be connected or linked to a display device, a display panel may include a plurality of areas, wherein a camera, a sensor, etc. may be arranged within an inner area of ​​the display area, and a display device including the display panel may be provided. However, in this case, as the wiring detours through the plurality of areas (e.g., bends around the plurality of areas), the blind area may be increased.

[0114] In contrast, one or more embodiments may provide a structure whereby the blind areas around the above-mentioned multiple areas may be reduced. That is, according to one or more embodiments, the signal lines around the area corresponding to the electronic component (e.g., a sensor or a camera) are arranged asymmetrically, and thus the blind area between the display area and the area corresponding to the electronic component may be reduced.

[0115] Example embodiments have been disclosed herein, and although specific terms are employed, they are used and will be construed only in a general and descriptive sense, and not for purposes of limitation. In some cases, as will be apparent to one of ordinary skill in the art from the time this application is filed, features, characteristics, and / or elements described in conjunction with a particular embodiment may be used alone, or in combination with features, characteristics, and / or elements described in conjunction with other embodiments, unless specifically noted otherwise. Therefore, it will be understood by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention as set forth in the claims.
