Abstract

A pixel structure which includes: a drive substrate; a first pixel definition layer, a pixel anode and a second pixel definition layer sequentially arranged on the drive substrate; a first metal structure arranged on the first pixel definition layer and a second metal structure arranged on the second pixel definition layer, where the pixel anode extends to a corresponding position below the second metal structure in the second pixel definition layer; a first insulation structure arranged on the first metal structure and a second insulation structure arranged on the second metal structure; an electroluminescent layer covering a portion of the first pixel definition layer, a portion of the pixel anode and a portion of the second pixel definition layer; and a pixel cathode covering the electroluminescent layer, where two ends of the pixel cathode are respectively connected to the first metal structure and the second metal structure.
