Abstract

The invention provides an OLED display panel. The OLED display panel includes an array substrate comprising a display zone and a non-display zone on the periphery of the display zone; a planarizationlayer arranged on the array substrate; a pixel definition layer arranged on the planarization layer; an OLED device arranged in a definition area of the pixel definition layer and penetrating throughthe planarization layer to contact with the array substrate; a package layer covering the OLED device, the pixel definition layer and the array substrate, wherein the contact faces of the pixel definition layer and the package layer in the non-display zone are non-planar contact faces. According to the invention, through arranging the contact faces of the pixel definition layer and the package layer as the non-planar contact faces, an organic layer in the package layer is blocked at the border of the pixel definition layer, the quantity of peripheral retaining walls is reduced and the peripheral area of the package layer is further reduced. Therefore, the narrow frame design of the OLED display panel is facilitated.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an OLED display panel. Background technique [0002] Organic light emitting diode (OLED) has excellent characteristics such as self-illumination, low energy consumption, wide viewing angle, rich colors, and fast response. OLED is considered to be a next-generation technology with great potential. [0003] Currently, OLED screens widely used in the display field generally adopt a top-emitting (top-emitting) device structure, and an OLED device is composed of an anode, an organic layer and a cathode. Wherein, the organic layer includes a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer and an electron injection layer. [0004] Since the organic layer and the cathode are very sensitive to water and oxygen, various means are required to encapsulate the organic light-emitting device when preparing a flexible OLED screen....
