A display panel. By providing auxiliary wiring (vg2), the impedance of a first level line (VGH) is reduced. Therefore, after a gating module (10a) is turned off, a signal input on the basis of the first level line (VGH) is pulled up as a data signal is driven high. Since the impedance of the first level line (VGH) is reduced, the time for the signal of the first level line (VGH) to return to normal can be speeded up, thereby reducing the risk of dark streaks caused by overcharging of a third node (Q).

Abrégé

Provided in the present application are a display panel and a display apparatus. In the display panel, a first gate insulating layer covers a second doped portion, and the first gate insulating layer does not cover a first doped portion, such that during the formation of the display panel, compared with the second doped region, the first doped portion is more likely to generate electrons when etched or subjected to ion bombardment, thereby differentiating threshold voltages of oxide semiconductor transistors in a pixel driving circuit and a gate driving circuit. Thus, the display panel can perform display normally.
