[0098] As shown in FIGS. 15 and 16, in some embodiments, each of the initialization signal lines The pattern 904 further includes a second protruding portion 9043 coupled to the first body portion 9041. In the same subpixel area, the positive projection of the second protruding portion 9043 on the base The shadow is a result of the orthogonal projection of the first body portion 9041 on the base and the reset signal line pattern. and the orthogonal projection of the first conductor portion 80 on the base. The orthogonal projection on the substrate 9042 of the second protruding portion 9043 and / or the first body portion 9041 It overlaps with the orthographic projection on the base.
[0099] Specifically, each of the initialization signal line patterns 904 further includes a second protruding portion 9043.

[0100] As described above, the orthogonal projection of the first conductor portion 80 on the base is part 9043 / or the orthogonal projection of the first body portion 9041 onto the base. With this configuration, the initialization signal line pattern 904 does not shield the first conductor portion 80. Therefore, all the initialization signals transmitted on the initialization signal line pattern 904 can be safely Since the signal is a fixed signal, such shielding prevents the above-mentioned The stability of the signal on the first conductor portion 80 can be guaranteed, and the floating of the first conductor portion 80 can be prevented. When an external data signal changes, the first conductor portion 80 is changed by the effect of capacitive coupling. The problem of signal instability is avoided.

There is a second gap L2 between the orthogonal projection, and the second gap L2 is larger than a threshold value.
[0102] Specifically, the first conductor portion 80 may have various shapes. 0 has a “gate” structure, i.e., the previous sub-pixel element in the first conductor portion 80 The end 801 close to the conductive connection pattern 909 in the rear extends along the second direction.

The signal line pattern 904 is coupled to the signal line pattern 904 .
[0106] Specifically, the positive throw of the first end 9091 of the conductive connection pattern 909 on the base The shadow is a positive projection of the first protruding portion 9042 of the initialization signal line pattern 904 on the base. The shadow can have a first overlap region F1, and the initialization signal line A second overlap also occurs with the orthogonal projection of the first body portion 9041 of the turn 904 on the base. It may have a region F2.
[0107] The first end 9091 of the conductive connection portion is connected to the initialization signal line port 70 through the first connection hole 70. When the first connecting hole 70 is connected to the turn 904, the orthogonal projection of the first connecting hole 70 on the base is The first overlap region F1 and the second overlap region F2 are overlapping regions. In this way, the layout space for the first connection hole 70 can be reduced.

In addition, due to process variations, the via hole may be misaligned and opened on the first conductor portion 80. This can more suitably avoid the problem of the signal being easily disturbed by the interference caused by the light. The yield is further preferably guaranteed.

It is completely covered by the orthographic projection above.
[0111] Specifically, the power signal line pattern 901 corresponds to the sub-pixel area one-to-one; The power supply signal line pattern 901 is located in the corresponding sub-pixel area. The power supply signal line patterns 901 provided in the pixel area are arranged in sequence along the second direction. and can be formed as a unitary structure.
[0112] As described above, the conductive portion 80 in the front subpixel area The end 802 far from the connection portion pattern 909 extends along the second direction, and the end 80 2, the orthogonal projections of the power supply signal line patterns on the base are located in the same sub-pixel area. 901 on the base, the orthogonal projection of the The source signal line pattern 901 is located in the front sub-pixel area of the first conductor portion 80. The end far from the conductive connection pattern 909 can be shielded. Since the power signals transmitted over the 01 are all stable signals, such shielding does not This ensures that the signal on the first conductor portion 80 remains stable when the external data signal changes. Due to the floating of one conductor portion 80, a capacitive coupling occurs when the external data signal changes. The problem of instability of the signal of the first conductor portion 80 due to the action of the ring is avoided.
[0113] In addition, according to the above-mentioned configuration method, the first conductive portion and the power supply signal line pattern 901 The layout space occupied by the display is effectively reduced, the pixel structure is advantageously reduced, and the display This will be advantageous as display panels become more highly resolvable.

As described above, the first power supply unit 90 is configured to be connected to the first direction. 11 is configured to be smaller than the width of the second power supply unit 9012, Since the width of the first power supply unit 9011 in the first direction is effectively narrowed, The overlap area between 9011 and the reset signal line pattern 905 is reduced. At the same time, the overlap between the first power supply part 9011 and the gate line pattern 902 As a result, the area of the power supply signal line pattern 901 and the reset signal line is reduced.
