Patent ID: 6862070

Claim:
A manufacturing method of a liquid crystal display comprising: a first step for forming a terminal section and a gate electrode made of a metal film on an insulation substrate; a second step for forming an insulation layer that covers the terminal section and the gate electrode; a third step for forming a semiconductor film and an ohmic contact film on a connection end portion of the terminal section and the gate electrode so that a film is patterned and formed on the terminal section and a semiconductor operation layer of a thin-film transistor is patterned and formed on the gate electrode by the semiconductor film and the ohmic contact film; a fourth step for forming wiring so that the connection end portion of the wiring is placed on the film; a fifth step for forming a contact hole by etching and removing the insulation layer by using the wiring as a mask; and a sixth step for connecting the wiring and the terminal section by a connection conductive film through the contact hole.
