Abstract:
1. A method of fabricating a liquid crystal display device comprising: forming a first thin film transistor in a driving circuit region by using a crystallized semiconductor layer as an active layer by providing a first substrate composed of a pixel region and a driving circuit region, forming an amorphous semiconductor layer having a first thickness on the first substrate, laterally crystallizing the amorphous semiconductor layer in a first direction, partially etching the crystallized semiconductor layer to a second thickness, and laterally crystallizing the partially etched crystallized semiconductor layer in a second direction perpendicular to the first direction; forming a second thin film transistor in the pixel region; forming a pixel electrode electrically connected to the second thin film transistor on the first substrate; providing a second substrate where a color filter layer is formed; attaching the first substrate and the second substrate to each other; and forming a liquid crystal layer between the first substrate and the second substrate.
