Patent ID: 7233020

Claim:
An organic light emitting display, comprising: a substrate having a unit pixel region; a thin film transistor located on the unit pixel region, said thin film transistor having a source electrode and a drain electrode; a via hole insulating layer located on the source electrode and the drain electrodes, said via hole insulating layer having a via hole that exposes one of the source electrode and the drain electrode; a first electrode overlapping with the via hole insulating layer and contacting with the exposed one of the source electrode and the drain electrode in the via-hole, said first electrode having a first part and a second part, said first part including at least a portion overlapping with the via hole; a first pattern formed on the first part of the first electrode and protruded upward as compared with the first electrode; a second pattern spaced apart from the first electrode, and protruded upward as compared with the second part of the first electrode, said second pattern not overlapping with the via-hole; and an emission layer located on the first electrode.
