Abstract:
1. A method of fabricating a display device, comprising: forming first to third active layers on a substrate, wherein the first active layer is formed in a display area of the substrate and the second and third layers are formed in a driver area of the substrate; forming a first insulating film on the active layers; directly forming a first conductive pattern including first, second, and third gate electrodes, a gate line connected to the first gate electrode, a storage line, and a pixel electrode on the first insulating film, wherein the first conductive pattern has a double-layer structure in which a metal layer is formed on a transparent conductive layer; forming source and drain region doped with a first impurity on the first and second active layers; forming source and drain regions doped with a second impurity on the third active layer; forming a second insulating film on the first conductive pattern; forming source and drain contact holes exposing the source and drain regions of the first, second and third active layers and forming a transmitting hole exposing the transparent conductive layer of the pixel electrode; and forming a second conductive pattern including data line and first, second and third source and drain electrodes connected to the source and drain regions of the first, second and third active layers, wherein the first drain electrode is connected to the transparent conductive layer of the pixel electrode.
