Abstract
An array substrate includes a base substrate, a pixel definition layer, a light-emitting layer, and a plurality of auxiliary electrodes. A pixel definition layer is formed on the base substrate, and includes patterned retaining walls and a plurality of openings defined by the retaining walls. A surface of each of the retaining walls facing away from the base substrate is provided with a first groove. A light-emitting layer is formed on the retaining wall and in the plurality of openings. The light-emitting layer conformally covers respective first grooves of the retaining walls to form respective second grooves. Each of the plurality of auxiliary electrodes is formed in a respective one of the second grooves.
