Abstract:
1. A manufacturing method of an array substrate for a transflective liquid crystal display device, comprising: forming a gate line and a gate electrode on a substrate; forming a gate insulator on the gate line and the gate electrode; forming an active layer on the gate insulator; forming an ohmic contact layer on the active layer; forming a data line, source and drain electrodes on the ohmic contact layer; depositing a first passivation layer made of a first material on the data line, source and drain electrodes; depositing a second passivation layer made of a second material on the first passivation layer; patterning the second passivation layer, thereby forming a first drain contact hole over the drain electrode; forming a reflector on the second passivation layer, the reflector having a first transmissive hole; patterning the first passivation layer, thereby forming a second drain contact hole exposing the drain electrode, the second drain contact hole corresponding to the first drain contact hole; and forming a transparent electrode on the second passivation layer and on the reflector, the transparent electrode being connected to the drain electrode through the first and second drain contact holes.
