Abstract
An array substrate, a method of manufacturing thereof, and a display device are provided. The array substrate includes a substrate, an array layer disposed on the substrate, an anode trace layer disposed on the array layer, a first pixel defining layer being an inorganic layer and disposed on the array layer, a first opening extending through the first pixel defining layer, a second pixel defining layer disposed on the first pixel defining layer, and a second opening extending through the second pixel defining layer. A projection of the first opening defined on the array layer completely falls within a projection of the second opening defined on the array layer. A light emitting region is defined by forming two pixel defining layers, so a color mixing problem is improved, and a pixel defining layer made of an inorganic material can improve a moisture barrier property of a pixel region.
