Patent ID: 7649202

Claim:
A light emitting display, comprising at least one first metal layer; a second metal layer crossing said at least one first metal layer and having a first width; a light emitting device formed adjacent to a region where said at least one first metal layer and the second metal layer cross each other; and a pixel circuit comprising at least one transistor for causing the light emitting device to emit light, and a driving transistor connected between a power line formed from said at least one first metal layer and the light emitting device, and including a gate terminal; wherein said at least one transistor comprises a semiconductor layer having a second width greater than the first width; and wherein the pixel circuit further comprises: a first capacitor having a first terminal connected to a first node, and having a second terminal connected to the gate terminal of the driving transistor; a first transistor controlled by a first scan signal applied to a first scan line formed from said at least one first metal layer, and connected between a data line formed from the second metal layer and the first node; a second transistor controlled by a second scan signal applied to a second scan line formed from said at least one first metal layer, and connected between the first node and the power line; a third transistor controlled by the second scan signal, and connected between the gate terminal of the driving transistor and a second node connected to an output terminal of the driving transistor; a fourth transistor controlled by the second scan signal, and connected between the second node and an anode electrode of the light emitting device; and a second capacitor connected between the first node and the power line.
