Organic light emitting display and manufacturing thereof |
摘要 |
An organic light emitting display and a manufacturing method that prevents an open edge from occurring when forming an emission layer of an organic light emitting display in order to prevent a dielectric breakdown from occurring at the edge of an anode electrode. The organic light emitting display includes: a substrate; an active layer formed on the substrate; a planarization layer formed on the active layer; an anode electrode formed on the planarization layer; a pixel definition layer formed on the upper surface of the planarization layer to cover an edge of the anode electrode; and an organic thin film formed on the pixel definition layer, wherein the pixel definition layer includes a thick film portion and a step down portion that is formed to be stepped down at both ends of the thick film portion. |
