Abstract

An array substrate includes: a base; light shield layers and a first auxiliary electrode that are disposed on the base; at least one insulating layer covering the light shield layers and the first auxiliary electrode; first electrodes that are disposed on the at least one insulating layer, a conductive connection portion; a pixel definition layer defining light-emitting regions and covering the conductive connection portion; organic light-emitting layers disposed on the first electrodes and located in the light-emitting regions defined by the pixel definition layer; and at least one second electrode covering the pixel definition layer and the organic light-emitting layers. A second electrode is electrically connected to the conductive connection portion through a via that penetrates through the pixel definition layer. The conductive connection portion is electrically connected to the first auxiliary electrode through a via that penetrates through the at least one insulating layer.
