Patent ID: 8362526

Claim:
A liquid crystal display device, comprising: a substrate comprising a pixel region and a driving region; first, second, and third active patterns formed on the substrate, the first and second active patterns being in the driving region, the third active pattern being in the pixel region, the first, second, and third active patterns each comprising an active region, a source region, and a drain region with the source and drain regions on opposing sides of the active region, each of the first and third active patterns further including first and second LDD regions and first and second LDE regions, the first LDD region being between the active region and the source region, the second LDD region being between the active region and drain region, the first LDE region being at the outer periphery of the source region, the second LDE region being at the outer periphery of the drain region, the source region being between the first LDD region and the first LDE region, the drain region bring between the second LDD region and the second LDE region; a gate insulator on the first, second, and third active patterns; first, second, and third gate electrodes on the gate insulator, the first, second, and third gate electrodes corresponding to the active regions of the first, second, and third active patterns, respectively; an interlayer insulating film comprising contact holes exposing each source and drain regions of the first, second, and third active patterns; first, second, and third source electrodes contacting the source region of the first, second, and third active patterns, respectively, through corresponding contact holes; and first, second, and third drain electrodes contacting the drain region of the first, second, and third active patterns, respectively, through corresponding contact holes.
