The third metal layer 14 comprises patterned source/drain electrodes 141 and a data line 142. The source/drain electrodes 141 are electrically connected to the active layer 11 through via holes penetrating the first gate insulating layer 400, the second gate insulating layer 500, and the interlayer insulating layer 600. The data line 142 crosses the scan line 122 in an insulated manner. A part of the data line 142 bypasses the light-transmitting area 30 and is wired in the ring-shaped wiring area 20. The data line 142 wired in the ring-shaped wiring area 20 comprises a first data line 142a and a second data line 142b. In this embodiment, there are one or more first data lines 142a and one or more second data lines 142b. Due to actual demand for a diameter of the blind/through hole 19, a plurality of the first data lines 142a and a plurality of the second data lines 142b are often required to be wired in the ring-shaped wiring area 20.

The anode layer 15 comprises a patterned anode electrode 151 and a second bridge line 152 disposed in the ring-shaped wiring area 20. The anode electrode 151 is connected to the drain electrode 141 through a via hole penetrating the planarization layer 700.
