PURPOSE: A method for manufacturing a liquid crystal display is to form a hydrophilic buffer layer on a hydrophobic passivation layer at an atmospheric pressure, thereby decreasing the process time. CONSTITUTION: A thin film transistor is formed on a transparent substrate(31). The thin film transistor includes a gate electrode(33), a gate insulating film(35), an active layer(37), an ohmic contact layer(39), a source electrode(41) and a drain electrode(43). A passivation layer(45) made of organic insulating material is coated on the transparent substrate to cover the thin film transistor. The passivation layer is patterned to form a contact hole(47) for exposing the drain electrode. The passivation layer is then UV(Ultraviolet)-cleaned to form a hydrophilic buffer layer(49). A pixel electrode(51) is formed to contact with the drain electrode through the contact hole.
