US 2022/0037433 A1 · ARRAY SUBSTRATE, DISPLAY APPARATUS, AND METHOD OF FABRICATING ARRAY SUBSTRATE

Abstract

An array substrate includes a flexible base substrate; a buffer layer on the flexible base substrate and continuously extending from a display area into a peripheral area, including a first portion substantially extending throughout the display area and a second portion in the peripheral area, the first portion and the second portion being parts of an integral layer, an organic insulating layer substantially extending throughout but limited in the display area and on a side of the buffer layer away from the flexible base substrate; an inorganic insulating layer limited in the peripheral area and on a side of the buffer layer away from the flexible base substrate; a planarization layer on a side of the organic insulating layer away from the buffer layer, and a plurality of light emitting elements on a side of the planarization layer away from the organic insulating layer.
