Method of manufacturing liquid crystal display device using first and second photoresists
Last updated:
Abstract:
Discussed is a method of manufacturing a LCD device, the method including: forming a gate in each of a plurality of pixel areas on a substrate; forming a gate insulator to cover the gate; forming a semiconductor layer on the gate insulator, and forming a photoresist (PR) on the semiconductor layer; doping high-concentration impurities at the semiconductor layer by using the photoresist (PR) as a mask to form an active layer, a source, and a drain; and doping low-concentration impurities at the semiconductor layer by using the photoresist (PR) as the mask to form a lightly doped drain (LDD) between the active layer and the source and between the active layer and the drain.
