Abstract

A flat panel display includes a thin film transistor formed on a substrate; a planarization layer formed on the thin film transistor; a first electrode layer formed on the planarization layer and electrically connected with the thin film transistor through the via hole formed in the planarization layer; a pixel definition layer formed on the planarization layer and in which an opening for at least partially exposing the first electrode layer is formed; an adhesive reinforcement layer formed at least between the planarization layer and the pixel definition layer on the top of the planarization layer; an emitting layer formed on the first electrode layer; and a second electrode layer formed on the emitting layer and the pixel definition layer. The flat panel display has an improved adhesive property between a pixel definition layer and a planarization layer, which prevents a chipping phenomenon of the pixel definition layer.
