ABSTRACT:
A CMOS-TFT array substrate and a method for fabricating the same is disclosed, by a low-mask technology to decrease the usage count of masks, which includes a substrate comprising an active area having a plurality of pixel regions and a driving circuit area for driving the active area, each pixel region having a transmitting part and a reflective part; a first semiconductor layer having first source/drain regions formed in the pixel region; a second semiconductor layer having second source/drain regions formed in the driving circuit area; a gate insulating layer on an entire surface of the substrate including the first and second semiconductor layers; first and second gate electrodes on the gate insulating layer above the first and second semiconductor layers; a storage electrode in the pixel region; an insulating interlayer on the entire surface of the substrate; a transmitting electrode on the insulating interlayer of the transmitting part; a passivation layer on the entire surface of the substrate including the transmitting electrode; a reflective electrode on the passivation layer of the reflective part; first and second source/drain electrodes being in contact with the first and second source/drain regions; and a liquid crystal layer between the substrate and another facing substrate.
