Abstract

Provided are organic light-emitting display panel, making method and display device. The display panel includes an array substrate including a display area and a non-display area, an organic light-emitting member and a encapsulation layer. A first buffer layer, a first and second insulation layer are placed in the non-display area; an antistatic ring is placed between the first and second insulation layers; a second buffer layer, a polysilicon layer, a gate insulation layer, a gate metallic layer, third and fourth insulation layers, a capacitor metallic layer, a source-drain metallic layer and a planarization layer are in the display area. The second and first buffer layers are made in a same process, the third and first insulation layers are made in a same process, the fourth and second insulation layers are made in a same process, and the antistatic ring and the gate metallic layer are made in a same process.
