Patent ID: 8305311

Claim:
An OLED display comprising: a first control electrode and a second control electrode formed on a substrate; a first crystalline semiconductor and a second crystalline semiconductor formed on the first control electrode and the second control electrode; a first input electrode and a first output electrode spaced apart from each other on the first crystalline semiconductor; a second input electrode and a second output electrode facing each other on the second crystalline semiconductor; an insulating layer formed on the first input electrode, the first output electrode, the second input electrode, and the second output electrode, and having a first contact hole exposing the first control electrode, a second contact hole exposing the first output electrode, a third contact hole exposing the second control electrode, and a fourth contact hole exposing the second output electrode; a gate line formed on the insulating layer and connected to the first control electrode through the first contact hole; a pixel electrode connected to the second output electrode through the fourth contact hole; a common electrode facing the pixel electrode; and a light emitting member disposed between the pixel electrode and the common electrode.
