Abstract: PURPOSE: A TN(Twisted Nematic) mode LCD device is provided to orient a rubbing direction toward a horizontal direction or a vertical direction while forming alignment layers, and to use a phase difference compensation film, thereby increasing a throughput and productivity. CONSTITUTION: Gate lines are formed in the first direction. A gate electrode is protruded from the gate lines. A gate insulating film(61) is formed on a front side of a lower substrate(59) by using a silicon nitride film or a silicon oxide film. A semiconductor layer is formed on the gate insulating film(61) by using an amorphous silicon. A metal having an excellent conductivity is formed on the lower substrate(59) where the semiconductor layer is formed. Source/drain electrodes and data lines are formed on both sides of the semiconductor layer by using a photo printing method and an etching method. A protective film(63) is formed by using an insulating material on a front side of the lower substrate(59). By removing the protective film(63) such that the drain electrode is exposed, a contact hole is formed.
