Abstract
A thin film transistor array substrate and a display panel are provided. The array substrate includes a substrate, a first metal layer, a first buffer layer, a second metal layer, a second buffer layer, an active layer, a gate insulating layer, a third metal layer, a passivation layer, and a fourth metal layer. By arranging the fourth metal layer on the passivation layer, an influence of water vapor in the environment on the array substrate is blocked, thereby improving a product yield and a reliability of the display panel.
