Abstract
A display panel and a method of manufacturing the display panel are provided. The display panel includes an array substrate, a planarization layer, a pixel defining layer, an organic light emitting device, and an inorganic layer disposed between the planarization layer and the pixel defining layer to block moisture and oxygen. An encapsulation structure of the array substrate is cooperatively formed by a combination of a first interlayer dielectric layer contained in a thin-film transistor, the planarization layer, and the inorganic layer.
