ABSTRACT:
A method of manufacturing a transflective type liquid crystal display device includes forming an organic film having different film thicknesses on a passivation film covering a TFT, etching the passivation film to form a contact hole, etching a reflective electrode and a transmissive electrode formed on the organic film by using a resist pattern having different film thicknesses, removing, by ashing, a thin film portion of the resist pattern, and a thin film portion of the organic film exposed from the transmissive electrode to form an opening, etching the reflective electrode by using the resist pattern left after the removal of the thin film portion, and bonding substrates in such a manner that a sealing material in a shape of a frame is arranged in the opening of the organic film.
