Abstract
A method for manufacturing the pixel definition layer includes forming a photolithographic material film on a substrate; performing a pre-drying treatment, a first exposure treatment, and a development treatment sequentially on the photolithographic material film to form an initial pattern of the pixel definition layer; and performing a second exposure treatment and a curing treatment sequentially on the initial pattern to form a final pattern of the pixel definition layer.
