Not only can the conductive connection have a larger area for covering the wire, The layout position of the first end 9091 of the pattern 909 and the first conductor portion 80 is closer. It is advantageous for saving pixel space and is also suitable for the development of high resolution display panels. It is advantageous for realization.

In the same sub-pixel area, the normal projection of the second protruding portion 9043 on the base The shadow is the result of the orthogonal projection of the first body portion 9041 on the base and the reset signal line pattern. the orthogonal projection of the first conductor portion 80 on the base of the first conductor portion 80. The orthogonal projection on the screen shows the base of the second protruding portion 9043 and / or the first body portion 9041. It overlaps with the orthographic projection on the source.
[0099] Specifically, each of the initialization signal line patterns 904 further includes a second protruding portion 9043. The second protruding portion 9043 may be specifically formed by connecting the first main body portion 9041 and the The second protruding portion 905 may be located between the reset signal line pattern 905. 043, the first protruding portion 9042 and the first body portion 9041 are formed as a unitary structure. It may be made.
[0100] As described above, the orthogonal projection of the first conductor portion 80 on the base is overlapping the orthogonal projection of the first body portion 9043 / or the first body portion 9041 on the base. By configuring in this manner, the initialization signal line pattern 904 does not shield the first conductor portion 80. Therefore, the initialization signals transmitted on the initialization signal line pattern 904 can be safely transmitted. Since the external data signal is a fixed signal, such shielding prevents the The stability of the signal on the first conductor portion 80 can be ensured, and the floating of the first conductor portion 80 When an external data signal changes, the first conductor portion 80 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 shape of the first conductor portion 80 may be various. For example, 0 has a "gate" structure, i.e., the previous sub-pixel element in the first conductor portion 80 The end 801 of the rear near the conductive connection pattern 909 extends along the second direction. The end 802 of the first conductor portion 80 that is close to the power signal line pattern 901 is A portion of the first conductor portion 80 extending along the second direction and positioned between these two ends extends along the first direction.

The first end 9091 of the conductive connection pattern 909 is connected to the first connection hole 70. 9. The signal line pattern 904 is coupled to the signal line pattern 904.
[0106] Specifically, the positive electrode 9091 of the first end 9091 of the conductive connection pattern 909 on the base The shadow is a normal 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 The orthogonal projection of the first body portion 9041 of the turn 904 onto the base also overlaps the second It may have a region F2.
[0107] The first end 9091 of the conductive connection part is connected to the initialization signal line pin 70 through the first connection hole. 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 overlap each other. In this way, the layout space of the first connection hole 70 can be reduced. The conductive connection pattern 909 and the initialization pattern can be connected with each other with a high degree of accuracy. I can attest to this.
[0108] As shown in FIG. 18, in some embodiments, the The orthogonal projection of one conductor portion 80 onto the base 40 corresponds to the first conductor portion 80 in the front sub-pixel area. It does not overlap with the orthogonal projection of the connection hole 70 on the base 40 .

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

[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 sequentially along the second direction. and can be formed as a unitary structure.
[0112] As described above, the conductive portion 80 in the previous sub-pixel 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 first conductor portion 80 in the previous sub-pixel area. 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 capacitance coupling occurs when the external data signal changes. The problem of signal instability in the first conductor portion 80 due to the effect of the ring is avoided.

As described above, the first power supply unit 90 is configured to 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 along 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.
