Patent ID: 7893899

Claim:
An organic light emitting diode display, comprising: a substrate including a pixel region and a non-pixel region; and an electrostatic discharge circuit formed in the non-pixel region of the substrate, wherein the electrostatic discharge circuit comprises: a semiconductor layer formed on the substrate, a gate insulating layer formed on the semiconductor layer, a gate electrode formed on the gate insulating layer and at least partly overlapping the semiconductor layer, an interlayer dielectric layer formed on the gate electrode, and first and second source/drain electrodes formed on the interlayer dielectric layer, wherein at least the first source/drain electrode at least partly overlaps the semiconductor layer, wherein at least a portion of the first source/drain electrode overlapping the semiconductor layer does not overlap the gate electrode, and wherein the portion of the first source/drain electrode overlapping the semiconductor layer is spaced apart from the portion of the gate electrode overlapping the semiconductor layer in a direction, wherein the direction is both substantially parallel to the substrate and substantially perpendicular to a line intersecting the first and second source/drain electrodes.
