Display panel and display device

Abstract

The embodiment of the invention relates to the technical field of display, and discloses a display panel and a display device. The display panel comprises a substrate, an MOS transistor arranged on the substrate, a first insulating layer, a first metal film, a second insulating layer and a second metal film, wherein the grid electrode and the drain electrode of the MOS transistor or the grid electrode and the source electrode of the MOS transistor are in short circuit; the first insulating layer and the MOS transistor are arranged on the same layer; the first metal film is arranged on the first insulating layer, a first through hole is formed in the first insulating layer, and the first metal film is connected with the source electrode and the drain electrode through the first through hole; the second insulating layer and the first metal film are arranged on the same layer; the second metal film is arranged on the second insulating layer, a second through hole is formed in the second insulating layer, a first TP wire is connected with the first metal film connected with the electrode, which is not short-circuited, of the MOS transistor through the second through hole, and a first grounding wire is connected with the first metal film connected with the electrode, which is short-circuited, of the MOS transistor through the second through hole. According to the display panel and the display device provided by the invention, the product yield and reliability can be improved.

AI Technical Summary

Problems solved by technology

In the prior art, in order to improve the performance of the display panel, the TP metal layer lines are required to be thinner, but in the process of manufacturing the display panel, the TP metal layer lines will form ESD aggregation, which leads to the problem that the thin lines are easy to be broken down by ESD. In turn, the product yield rate is reduced, resulting in poor reliability of the product
