Abstract

The invention provides an organic light-emitting display panel comprising a substrate including a display region and a non-display region, wherein the non-display region comprises: an insulating layer disposed on the same side of a array layer and provided with at least one groove exposing the substrate; a metal layer comprising a first portion covering the groove and in contact with the substrate, and a second portion covering the outer side of the groove and in contact with the insulating layer; at least one shielding wall disposed on a side, away from the substrate, of the second portion and in contact with the second portion, wherein the material of the shielding wall comprises an organic substance. The organic light-emitting display panel can increase the bonding ability of the shielding wall and the substrate, reduce a peeling risk when being in contact with a mask plate, and prevent the expansion of cracks, increases a side wrapping effect in order that little water enters to corrode an organic light emitting device from the side.

Description

technical field [0001] The present invention relates to the field of organic light emitting displays, in particular to an organic light emitting display panel, an organic light emitting display device and a method for preparing the organic light emitting display panel. Background technique [0002] The organic light-emitting display device is a self-emission display device including an organic light-emitting device (OLED), and the organic light-emitting display device includes an organic light-emitting device including a first electrode, a second electrode, and an organic light-emitting device formed between the first electrode and the second electrode. luminous layer. In an organic light-emitting device, holes (electrons) injected from the first electrode and electrons (holes) injected from the second electrode combine in the organic light-emitting layer to generate excitons, which fall from an excited state to a ground state and generate Light. [0003] An organic light ...
