Abstract
An array substrate may include a base substrate and a pixel defining layer on the base substrate. The pixel defining layer may include a plurality of thickness thinning regions. The thickness thinning regions may have a smaller height than other areas of the pixel defining layer on the base substrate. The plurality of the thickness thinning regions may be configured to guide flow of fillers to form an encapsulating layer on the pixel defining layer.
