Patent ID: 7776668

Claim:
A method for manufacturing a liquid crystal display, the method comprising: simultaneously forming a gate electrode on a transparent dielectric substrate; simultaneously forming a TFT including a channel layer, an ohmic contact layer, and source/drain electrodes by forming a gate insulation film, an amorphous silicon film, a doped amorphous silicon film, and a metal film on the transparent dielectric substrate on which the gate electrode is formed and etching the metal film, the amorphous silicon film, and the doped amorphous silicon film; forming a protective film on the transparent dielectric substrate; forming a photoresist film on the protective film and patterning the photoresist film to exist on the TFT; and forming a pixel electrode by forming a transparent metal film on the transparent dielectric substrate and removing the photoresist film and a portion of the transparent metal film on the TFT through a lift-off process using a stripper solution, wherein the stripper solution finely etches and removes transparent metal particles generated during the formation of the pixel electrode.
