Patent ID: 7443095

Claim:
An organic light emitting display, comprising: a substrate; a thin film transistor formed on the substrate; a passivation layer formed over the thin film transistor; a planarization layer formed on an entire surface of the passivation layer; a first electrode formed in a predetermined region on the planarization layer and connected to any one of source and drain electrodes of the thin film transistor through a via hole formed in the planarization layer and the passivation layer; a pixel defining layer formed on the planarization layer and the first electrode, said pixel defining layer being patterned to form an opening exposing at least a part of the first electrode; an organic layer pattern formed on the opening of the first electrode and on both ends of the patterned pixel defining layer, said organic layer pattern including at least an emission layer; and a second electrode formed on the organic layer pattern; wherein a height of the pixel defining layer formed on the planarization layer in a region where the first electrode is not formed is not greater than a height of the pixel defining layer formed on the first electrode.
