Abstract
Disclosed are an array substrate and a display panel. The array substrate includes a TFT device layer; a pixel definition layer arranged in a non-via area of a non-opening area of the TFT device layer, the non-opening area including a via area and the non-via area; a barrier wall arranged at the via area and in an inverted trapezoid shape; an organic light emitting diode layer arranged on an upper end of the barrier wall and an upper end of part of auxiliary electrodes in the via area; and a cathode arranged on the upper end of the part of the auxiliary electrodes in the via area. This application may alleviate the uneven distribution of cathode voltage to improve the brightness uniformity of the display panel.
