[0149] Fig. 7A is a plan view of one pixel among the pixels P of the display panel 10 according to the embodiment, and Figure 7B is along Fig. 7A A cross-sectional view taken along line AA' and line BB'.
[0150] refer to Fig. 7A and Figure 7BThe driving thin film transistor T1, the switching thin film transistor T2, the compensation thin film transistor T3, the first initialization thin film transistor T4, the operation control thin film transistor T5, the emission control thin film transistor T6 and the second initialization thin film transistor T7 are arranged along the semiconductor layer 1130. Figure 7B As shown in , a semiconductor layer 1130 is located above a substrate 100 , and a buffer layer 2111 including an inorganic material such as silicon oxide, silicon nitride, and silicon oxynitride is formed below the semiconductor layer 1130 .

The driving channel region C1 overlapping the driving gate electrode G1 can form a long channel length in a narrow space by having a curved shape such as an Ω shape. In the case where the length of the driving channel region C1 is long, the driving range of the gate voltage becomes wide, and thus the grayscale of the light emitted from the organic light emitting diode OLED can be more delicately controlled, and thus the display quality can be improved.

The electrode voltage line HL may be understood as a lateral driving voltage line.
[0171] Since the driving voltage line PL extends in the y direction and the electrode voltage line HL electrically connected to the driving voltage line PL extends in the x direction different from the y direction, the plurality of driving voltage lines PL and the plurality of electrode voltage lines HL may constitute a mesh structure in the display area DA.

For example, in the case where the first functional layer 221 includes a polymer material, the first functional layer 221 may include a hole transport layer (HTL) having a single layer structure, and may include poly-(3,4)-ethylene-dihydroxythiophene (PEDOT) or polyaniline (PANI). In the case where the first functional layer 221 includes a low molecular weight material, the first functional layer 221 may include a hole injection layer (HIL) and the HTL.
[0181] The second functional layer 223 may be omitted.

In an embodiment, Figure 8At least one of the arc-shaped curves shown in FIG. 1 conforms to an arc of a geometric circle, and in a plan view of the display panel 10 , the geometric circle is concentric with the perimeter of the opening area OA.
[0190] exist Figure 8 In the embodiment, the pixels P located above and below the opening area OA are electrically connected to the data lines DL1, DL2, DL3, DL4, DL5, DL6, DL7, and DL8 arranged around the opening area OA, and can receive data signals through the connected data lines. The data lines DL1, DL2, DL3, and DL4 can be arranged around the opening area OA at a first side (e.g., the left side) of the opening area OA, and the data lines DL5, DL6, DL7, and DL8 can be arranged around the opening area OA at a second side (e.g., the right side) of the opening area OA.
[0191] The scan lines SWL0, SWL1, SWL2, SWL3, SWL4, SWL5, SWL6, SWL7, SWL8, and SWL9 and the previous scan lines SIL0, SIL1, SIL2, SIL3, SIL4, SIL5, SIL6, SIL7, SIL8, and SIL9 may extend substantially in the x direction different from the y direction. Some of the scan lines (e.g., the scan lines SWL1, SWL2, SWL3, SWL4, SWL5, SWL6, SWL7, and SWL8) may be arranged around the opening area OA. In addition, some of the previous scan lines SIL0, SIL1, SIL2, SIL3, SIL4, SIL5, SIL6, SIL7, SIL8, and SIL9 (e.g., the previous scan lines SIL1, SIL2, SIL3, SIL4, SIL5, SIL6, SIL7, and SIL8) may be arranged around the opening area OA. For example, the scan lines SWL1, SWL2, SWL3 and SWL4 and the previous scan lines SIL1, SIL2, SIL3 and SIL4 can be arranged around the opening area OA on a third side (e.g., an upper side) of the opening area OA, and the scan lines SWL5, SWL6, SWL7 and SWL8 and the previous scan lines SIL5, SIL6, SIL7 and SIL8 can be arranged around the opening area OA on a fourth side (e.g., a lower side) of the opening area OA.

[0194] In the first non-display area NDA1, the emission control line of one of the two adjacent pixels may be connected to the emission control line of the other pixel. For example, the first emission control line EL1 on the first pixel row that transmits the emission control signal to the pixels P disposed on the left and right sides of the opening area OA of the first pixel row may be connected to the second emission control line EL2 on the second pixel row in the first non-display area NDA1. For example, in the first non-display area NDA1, the first emission control line EL1 may be connected to the detour line EL-C of the second emission control line EL2. If the emission control lines EL1 and EL2 are not connected to each other and have detour lines EL-C respectively, the number of emission control lines passing through the first non-display area NDA1 may be undesirably large. In an embodiment, since the first emission control line EL1 is connected to the detour line EL-C of the second emission control line EL2 in the first non-display area NDA1, in other words, since the first emission control line EL1 and the second emission control line EL2 share the detour line EL-C, the number of detour lines of the emission control lines passing through the first non-display area NDA1 may be advantageously minimized.

[0199] The intermediary metal ML may be located on the second interlayer insulating layer 2150. The intermediary metal ML may be connected to the extension portion EL-E through the contact holes CNT1-1 of the interlayer insulating layers 2143 and 2150, respectively, and the detour line EL-C may be connected to the intermediary metal ML through the contact hole CNT1-2. The intermediary metal ML may include a metal member disposed only in a region corresponding to the first contact hole CNT1, and may include the same material as that of the data line. The detour line EL-C on the planarizing insulating layer 2180 may include a contact hole CNT1-2 that is the same as that of the reference line. Figure 7B The material of the pixel electrode 210 is the same material as described.

[0207] This embodiment can minimize the number of emission control drivers. Since the number of emission control drivers is minimized, the space occupied by the emission control drivers can be advantageously minimized. Additional drivers can be further arranged in areas 1A, 2A, 3A, and 4A. Advantageously, the utilization of the non-display area can be optimized.

[0212] The emission control lines EL1 and EL2 on the left side of the opening area OA are connected to each other, and the emission control lines EL1 and EL2 on the right side of the opening area OA are connected to each other. Since there is no detour line EL-C, the emission control lines EL1 and EL2 on the left side of the opening area OA are electrically isolated from the emission control lines EL1 and EL2 on the right side of the opening area OA. Similarly, the emission control lines EL3 and EL4, the emission control lines EL5 and EL6, and the emission control lines EL7 and EL8 do not include the detour line EL-C connecting the left and right sides of the opening area OA.

[0219] The first emission control signal output from the second emission control driver ED2 may be transmitted as a carry signal to the fourth emission control driver ED4 disposed on the right side of the second non-display area NDA2. The fourth emission control driver ED4 may provide the second emission control signal to the emission control lines EL3 and EL4 at the same time, and the second emission control signal may be provided to the pixel P disposed on the right side of the opening area OA through the extension portion EL-E of the emission control lines EL3 and EL4.

[0222] According to the above-described embodiment, the first non-display area NDA1 may be minimized by minimizing the number of detour lines EL-C around the opening area OA.
[0223] Figures 14 to 17 1 is a plan view of at least a scan line, a previous scan line, and a scan driver of the display panel 10 according to the embodiment. Features different from the above-described features are mainly described.
[0224] refer to Fig.14 , scan drivers SD1, SD2, SD3, SD4, SD5, SD6, SD7, SD8, SD9, SD10, SD11, SD12, SD13, SD14, SD15 and SD16 are disposed in the second non-display area NDA2. The structures of emission control lines EL1, EL2, EL3, EL4, EL5, EL6, EL7 and EL8 are similar to those of Fig.10 The structure of the embodiment is the same. Fig.14 , but an emission control driver configured to provide an emission control signal to the emission control lines EL1, EL2, EL3, EL4, EL5, EL6, EL7, and EL8 may be connected to Fig.10 The emission control drivers ED1, ED2, ED3 and ED4 shown in FIG. 1 are identical.
[0225] exist Fig.10 In an embodiment, each of the scan lines SWL1, SWL2, SWL3, SWL4, SWL5, SWL6, SWL7, and SWL8 and the previous scan lines SIL1, SIL2, SIL3, SIL4, SIL5, SIL6, SIL7, and SIL8 may extend substantially in the x-direction and surround the opening area OA. In an embodiment, the material of the scan line SWL1 may be different from that of the previous scan line SIL1. Fig.14 In the present embodiment, a scanning line and a previous scanning line included in a pixel row are connected to each other, and a bypass line SWL-C connecting the scanning line and the previous scanning line is provided.
[0226] For example, in the first non-display area NDA1, the first previous scan line SIL1 is connected to the bypass line SWL-C of the first scan line SWL1. In other words, the first previous scan line SIL1 and the first scan line SWL1 share the bypass line SWL-C. Similarly, each group in the group ranging from the group including the second previous scan line SIL2 and the second scan line SWL2 to the group including the eighth previous scan line SIL8 and the eighth scan line SWL8 includes only one bypass line SWL-C. In an embodiment, adjacent bypass lines may be located on different insulating layers (i.e., directly contacting different insulating layers, respectively). For example, the bypass line SWL-C of the first scan line SWL1 and the bypass line SWL-C of the second scan line SWL2 may be located on different insulating layers. Advantageously, the first non-display area NDA1 around the opening area OA may be minimized.
[0227] Scan drivers SD1, SD2, SD3, SD4, SD5, SD6, SD7, SD8, SD9, SD10, SD11, SD12, SD13, SD14, SD15 and SD16 are arranged at two opposite sides of the second non-display area NDA2 and in the second non-display area NDA2, and two scan drivers can be connected to a pixel row having pixels located at two opposite sides of the opening area OA.
[0228] For example, the first scan driver SD1 disposed on the left side of the second non-display area NDA2 and the second scan driver SD2 disposed on the right side of the second non-display area NDA2 provide scan signals to the first previous scan line SIL1 and the first scan line SWL1 at the same time. The third scan driver SD3 disposed on the left side of the second non-display area NDA2 and the fourth scan driver SD4 disposed on the right side of the second non-display area NDA2 provide scan signals to the second previous scan line SIL2 and the second scan line SWL2 at the same time. Similarly, the fifteenth scan driver SD15 disposed on the left side of the second non-display area NDA2 and the sixteenth scan driver SD16 disposed on the right side of the second non-display area NDA2 provide scan signals to the eighth previous scan line SIL8 and the eighth scan line SWL8 at the same time. Since the scan signals are provided from the left and right sides of the display area DA at the same time, the scan signal delay can be prevented, and thus the display quality can be improved.
[0229] Four scan drivers are provided in each of the regions 1A, 2A, 3A, and 4A. Since the emission control drivers ED1, ED2, ED3, and ED4 (see FIG. 1 ) provided in each of the regions 1A, 2A, 3A, and 4A Fig.10 ) is small, so a sufficient number of scan drivers can be set in each of the areas 1A, 2A, 3A and 4A.
[0230] The material of a scan line connected in a pair and a previous scan line may be different from the material of an immediately adjacent scan line connected in a pair and a previous scan line.
[0231] refer to Fig.15 , when Fig.14 When compared with the display panel 10 of FIG. 1 , the structure of the scan line is different from that of the previous scan line. Fig.14 In the display panel 10, all of the scanning lines and the previous scanning lines are formed on the same layer. Fig.15 In the display panel 10 of the present embodiment, the first scan line SWL1 and the first previous scan line SIL1 are connected to each other through the detour line SWL-C. The detour line SWL-C of the first scan line SWL1, the connection portion SWL-E, and the connection portion SIL-E of the first previous scan line SIL1 are arranged on different layers with at least an intermediate insulating layer, and are connected through contact holes CNT3 and CNT4.
[0232] refer to Fig.16 , not formed Fig.14 The first non-display area NDA1 may be advantageously minimized by minimizing the number of the detour lines SWL-C around the opening area OA.
[0233] refer to Fig.17, the scan line and the paired previous scan line may be disconnected at the periphery of the first non-display area NDA1 relatively close to the opening area OA. The scan lines SWL1, SWL2, SWL3, SWL4, SWL5, SWL6, SWL7 and SWL8 and the previous scan lines SIL1, SIL2, SIL3, SIL4, SIL5, SIL6, SIL7 and SIL8 that have extended from the left and right parts of the second non-display area NDA2 to the display area DA may not extend into the first non-display area NDA1. By minimizing the number of wirings provided in the first non-display area NDA1, the first non-display area NDA1 may be advantageously minimized.
[0234] According to an embodiment, the area of the non-display area NDA may be minimized by minimizing the number of detour lines for connecting lines in the first non-display area NDA1 around the opening area OA in the display device 1 .
