For example, the input sensing layer 40 may be continuously formed after the process of forming the display panel 10. In this case, no adhesive layer may be arranged between the input sensing layer 40 and the display panel 10. In an embodiment, as shown in FIG.

In an embodiment, at least one of the display panel 10, the input sensing layer 40, and the optical function layer 50 may not include an opening. For example, one or two of the display panel 10, the input sensing layer 40, and the optical function layer 50 may not include an opening. In the following, the opening area OA may represent at least one of the first opening 10H, the second opening 40H, and the third opening 50H of the display panel 10, the input sensing layer 40, and the optical function layer 50. For example, in the present specification, the opening area OA may represent the first opening 10H of the display panel 10.

[0068] The component 20 may correspond to, align with, overlap, or be located in the opening area OA. Figure 2 As shown by the solid lines, the component 20 may be located inside the first opening 10H, the second opening 40H, and the third opening 50H, or as shown by the dotted lines, the component 20 may be located below the display panel 10.

[0072] FIG. 3A to FIG. 3C A cross-sectional view of a display panel 10 according to an embodiment is shown.

[0073] Reference FIG. 3A to FIG. 3C The display panel 10 may include a display element layer 200 located on a substrate 100. The substrate 100 may include a glass material or a polymer resin. For example, the substrate 100 may include a SiO 2 A glass material as a main component, or a resin such as reinforced plastic may be included.

A sealing material 350 may be located between the substrate 100 and the encapsulation substrate 340. The sealing material 350 may surround the display element layer 200 between the substrate 100 and the encapsulation substrate 340. For example, the sealing material 350 may surround a first edge (also referred to as an inner edge) of the display element layer 200 in the first non-display area NDA1, and surround a second edge (also referred to as an outer edge) of the display element layer 200 in the second non-display area NDA2. When viewed in a direction perpendicular to the main surface of the substrate 100, the opening area OA may be completely surrounded by the sealing material 350, and the second edge of the display element layer 200 may also be completely surrounded by the sealing material 350.

[0076] The display panel 10 may include a first opening 10H corresponding to the opening area OA. Figure 3A 2 shows that the substrate 100 and the packaging substrate 340 include through holes 100H and 340H corresponding to the opening area OA, respectively. The display element layer 200 may also include a through hole corresponding to the opening area OA.

[0077] In an embodiment, if Figure 3B As shown in , the package substrate 340 may include a through hole 340H corresponding to the opening area OA, but the substrate 100 may not include a through hole. Figure 3C As shown in , the substrate 100 and the encapsulation substrate 340 may not include a through hole corresponding to the opening area OA, respectively. The display element layer 200 may include a through hole corresponding to the opening area OA. In an embodiment, the sealing material 350 arranged in the first non-display area NDA1 of the display panel 10 may be omitted. In an embodiment, the display element layer 200 may not include a through hole corresponding to the opening area OA. A component 20 with relatively high transmittance is not required (see Figure 2 ) may be arranged in the opening area OA, and the opening area OA may be used as a transmission area that transmits light used by the component 20. Even when the display element layer 200 does not include a through hole corresponding to the opening area OA, the portion of the display element layer 200 corresponding to the opening area OA may be formed by not including a pixel circuit PC (see Figure 6 and Fig. 7A ) elements (e.g., transistors, storage capacitors, wiring, etc.) to ensure transmittance.

[0078] FIG. 4A to FIG. 4C is a cross-sectional view of a display panel 10 ′ according to another embodiment.

In an embodiment, as Figure 4A As shown in FIG. 1 , there may be a first inorganic encapsulating layer 310 ′ and a second inorganic encapsulating layer 330 ′, and the organic encapsulating layer 320 ′ may be located between the first inorganic encapsulating layer 310 ′ and the second inorganic encapsulating layer 330 ′.

[0080] The first inorganic encapsulation layer 310' and the second inorganic encapsulation layer 330' may include one or more inorganic materials among 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. The polymer material may include acrylic resin, epoxy resin, polyimide and polyethylene.

[0081] The substrate 100 may include a polymer resin and include a plurality of layers. For example, the substrate 100 may include a first base layer 101, a first barrier layer 102, a second base layer 103, and a second barrier layer 104 that are sequentially stacked.

[0082] Each of the first base layer 101 and the second base layer 103 may include a polymer resin. For example, the first base layer 101 and the second base layer 103 may include a polymer resin such as polyethersulfone (PES), polyarylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyimide (PI), polycarbonate (PC), triacetyl cellulose (TAC), and cellulose acetate propionate (CAP).

[0086] In an embodiment, if Figure 4B As shown in , the organic encapsulation layer 320' of the encapsulation member 300' which is a thin film encapsulation layer may include a through hole 320H' corresponding to the opening area OA, but the substrate 100 and the first and second inorganic encapsulation layers 310' and 330' may not include a through hole, respectively. Figure 4C As shown in , the layer of the encapsulation member 300' constituted as a thin film encapsulation layer may not include a through hole corresponding to the opening area OA. For example, the first inorganic encapsulation layer 310' and the second inorganic encapsulation layer 330' and the organic encapsulation layer 320' may cover the opening area OA. In an embodiment, in the case where the opening area OA is used as a transmission area for transmitting light, for example, in a component 20 (see FIG. 20 ) that does not require high transmittance Figure 2 ) is arranged in the opening area OA, FIG. 4A to FIG. 4C Different from that shown in FIG. 1 , the display element layer 200 may not include a through hole corresponding to the opening area OA. Even when the display element layer 200 does not include a through hole corresponding to the opening area OA, the portion of the display element layer 200 corresponding to the opening area OA may be formed by not including a pixel circuit PC (see FIG. 1 ).

Some of the emission control lines EL0, EL1, EL2, EL3, EL4, EL5, EL6, and EL7 (e.g., the first to sixth emission control lines EL1, EL2, EL3, EL4, EL5, and EL6) may be arranged around the opening area OA. For example, the first to third emission control lines EL1, EL2, and EL3 may be arranged around the opening area OA on the upper side of the opening area OA, and the fourth to sixth emission control lines EL4, EL5, and EL6 may be arranged around the opening area OA on the lower side of the opening area OA.

[0155] Each of the first to sixth emission control lines EL1, EL2, EL3, EL4, EL5, and EL6 includes an extension portion EL-E located in the display area DA and a detour portion EL-C located in the first non-display area NDA1. The extension portion EL-E and the detour portion EL-C may be located on different layers (e.g., at different distances from the substrate 100), respectively. Fig. 9 , the extension portion EL-E of the sixth emission control line EL6 may be located (e.g., directly located) on the gate insulating layer 2141, and the detour portion EL-C of the sixth emission control line EL6 may be located (e.g., directly located) on the planarization insulating layer 2180. The extension portion EL-E and the detour portion EL-C of the sixth emission control line EL6 may be electrically connected to each other through the first contact hole CNT1, and the middle metal ML may be located therebetween. In an embodiment, the extension portion EL-E of the sixth emission control line EL6 may be located (e.g., directly located) on the first interlayer insulating layer 2143.

[0156] The middle metal ML may be located on the second interlayer insulating layer 2150. The middle metal ML may be connected to the extension portion EL-E through the (1-1)th contact hole CNT1-1 of the first interlayer insulating layer 2143 and the second interlayer insulating layer 2150, respectively, and the detour portion EL-C may be connected to the middle metal ML through the (1-2)th contact hole CNT1-2, respectively. The middle metal ML may include an island metal disposed only in a region corresponding to the first contact hole CNT1, and include the same material as that of the data line. The detour portion EL-C on the planarizing insulating layer 2180 may include the same material as that of the reference Figure 7B The same material as the material of the pixel electrode 210 described above. Fig. 9 Similar to the structure of the sixth emission control line EL6 shown in FIG, each of the first to fifth emission control lines EL1, EL2, EL3, EL4, and EL5 may include an extending portion EL-E and a detour portion EL-C respectively arranged in different layers.

[0157] The interval between adjacent data lines in the first non-display area NDA1 (eg, the interval d between the detour portions of the adjacent data lines) may be larger than the interval D between adjacent data lines in the display area DA (see FIG. 1 ). Figure 8 ) is small. The display quality of some pixels in the display area DA may be degraded due to coupling caused between the detour portions of the data lines arranged with a relatively narrow interval d. In contrast, according to an embodiment, the detour portion EL-C may be arranged between adjacent data lines in the first non-display area NDA1, which can minimize the problem caused by the occurrence of the above-mentioned coupling.

[0158] In the first non-display area NDA1, the detour portions of the first to sixth scan lines SWL1, SWL2, SWL3, SWL4, SWL5 and SWL6 and the detour portions of the first to sixth previous scan lines SIL1, SIL2, SIL3, SIL4, SIL5 and SIL6 may be located on a layer different from a layer on which the detour portions EL-C of the first to sixth emission control lines EL1, EL2, EL3, EL4, EL5 and EL6 are arranged. At the same time, in the first non-display area NDA1, the detour portions of the first to sixth scan lines SWL1, SWL2, SWL3, SWL4, SWL5 and SWL6 and the detour portions of the first to sixth previous scan lines SIL1, SIL2, SIL3, SIL4, SIL5 and SIL6 can be separated from each other without overlapping with the detour portions EL-C of the first to sixth emission control lines EL1, EL2, EL3, EL4, EL5 and EL6.

[0159] For example, Fig.10 As shown in , the detour portion EL-C of the second emission control line EL2, the second scan line SWL2, and the second previous scan line SIL2 between the fourth data line DL4 and the fifth data line DL5 adjacent to each other may be spaced apart from each other. For example, when the display panel 10 is viewed from a direction perpendicular to the top surface of the substrate 100, the fourth data line DL4 may be spaced apart from the detour portion EL-C of the second emission control line EL2 (e.g., laterally) by a first interval d1, the detour portion EL-C of the second emission control line EL2 may be spaced apart from the second scan line SWL2 by a second interval d2, the second scan line SWL2 may be spaced apart from the second previous scan line SIL2 by a third interval d3, and the second previous scan line SIL2 may be spaced apart from the fifth data line DL5 by a fourth interval d4.

[0160] like Figure 8As shown in , the initialization voltage line VL of each pixel P may extend in the x direction in the display area DA, and the initialization voltage line VL that transmits the initialization voltage to the pixels arranged in the left and right sides of the opening area OA may be disconnected around the opening area OA. The initialization voltage line VL disconnected around the opening area OA may be connected to the electrode layer VL-R arranged in the first non-display area NDA1 through the second contact hole CNT2. The electrode layer VL-R may have a ring shape surrounding the opening area OA.

[0161] As mentioned above Fig. 7A and Figure 7B As described, the initialization voltage line VL may be disposed on the first interlayer insulating layer 2143, and the electrode layer VL-R may be disposed on the planarization insulating layer 2180. The electrode layer VL-R may be connected to the initialization voltage line VL through the second contact hole CNT2.

[0162] Fig.11 A plan view of emission control lines and an emission control driver in the display panel 10 according to an embodiment is shown. Fig.11 The first emission control lines EL1, EL2, EL3 and EL4 are the same as those in the above reference Figures 8 to 10 The descriptions of the first to fourth emission control lines EL1, EL2, EL3, and EL4 correspond.

[0163] The first emission control line EL1 can be Fig.11 The first emission control driver 120Aa in the second non-display area NDA2 on the right side of the opening area OA receives the emission control signal, and the relevant signal can be provided to the pixels arranged on the left and right sides of the opening area OA respectively through the extension portion EL-E, the detour portion EL-C and the other extension portion EL-E of the first emission control line EL1. Similarly, the second emission control line EL2 can be provided from the pixels located at Fig.11 The second emission control driver 120Ab in the second non-display area NDA2 on the right side receives the emission control signal, and the relevant signal can be provided to the pixels respectively arranged on the left and right sides of the opening area OA through the extending portion EL-E, the bypass portion EL-C and the other extending portion EL-E of the second emission control line EL2.

[0164] The third emission control line EL3 can be Fig.11 The third emission control driver 110Aa in the second non-display area NDA2 on the left side of the opening area OA receives the emission control signal, and the relevant signal can be provided to the pixels arranged on the left and right sides of the opening area OA respectively through the extension portion EL-E, the detour portion EL-C and the other extension portion EL-E of the third emission control line EL3. Similarly, the fourth emission control line EL4 can be provided from the pixels located at Fig.11 The fourth emission control driver 110Ab in the second non-display area NDA2 on the left side receives the emission control signal, and the relevant signal can be provided to the pixels respectively arranged on the left and right sides of the opening area OA through the extended portion EL-E, the bypass portion EL-C and the other extended portion EL-E of the fourth emission control line EL4.

[0165] In some other devices, if the first emission control lines EL1 are spaced apart from each other around the opening area OA without including the detour portion EL-C (for example, the first emission control line EL1 includes only the extension portion EL-E), a pair of first emission control drivers 120Aa are required in the second non-display area NDA2 on the left and right sides of the display area DA, respectively. Similarly, in the case where the second to fourth emission control lines EL2, EL3, and EL4 are spaced apart from each other around the opening area OA without including the detour portion EL-C, a pair of second to fourth emission control drivers 120Ab, 110Aa, and 110Ab are required in the second non-display area NDA2 on the left and right sides of the display area DA, respectively. In this case, the area of ​​the second non-display area NDA2 is increased.

[0166] On the contrary, according to the embodiment, Fig.11 As shown in FIG. 1 , each of the first to fourth emission control lines EL1, EL2, EL3, and EL4 may include a detour portion EL-C connected to the extension portion EL-E, which may reduce the number of lines arranged in the Fig.11 The number of emission control drivers in the second non-display area NDA2 and the area of ​​the second non-display area NDA2 are determined.

[0167] In an embodiment, if Fig.11 As shown in , the first to fourth emission control drivers 120Aa, 120Ab, 110Aa, and 110Ab may be alternately arranged in pairs on the left and right sides around the display area DA. In an embodiment, the first to fourth emission control drivers 120Aa, 120Ab, 110Aa, and 110Ab may be alternately arranged in the second non-display area NDA2 located on the left and right sides around the display area DA, respectively. For example, the first emission control driver 120Aa and the second emission control driver 120Ab may be arranged in the second non-display area NDA2 located on the right side of the display area DA, and the third emission control driver 110Aa and the fourth emission control driver 110Ab may be arranged in the second non-display area NDA2 located on the left side of the display area DA.
