Forming a gate electrode; Sequentially depositing a gate insulating film, an amorphous silicon layer, and a doped semiconductor layer on the entire surface of the device; Patterning the amorphous silicon layer and the doped semiconductor layer into a predetermined shape; Sequentially forming an ITO layer and a metal layer on the entire structure; Etching the ITO layer and the metal layer in the form of a source electrode, a drain electrode, and a pixel electrode; Forming a protective film on the entire structure; Etching a portion of the passivation layer and the metal layer to expose the ITO electrode in the pixel electrode region. According to this, the thin film transistor and the pixel electrode of the liquid crystal display device formed by the seven mask patterns according to the conventional method are formed by using the four mask pattern films to form the thin film transistor and the pixel electrode of the liquid crystal display device, thereby simplifying the manufacturing process. It can reduce the air and cost.
