  • Publication number: 20070154845
    Abstract: A method for fabricating a liquid crystal display includes: forming a gate electrode on a substrate; sequentially providing an insulation layer, a semiconductor layer and an etch stopper layer on the gate electrode; patterning the etch stopper layer and the semiconductor layer to form an etch stopper layer pattern and a semiconductor layer pattern; removing both side portions of the etch stopper layer pattern to expose the lower semiconductor layer pattern portion; forming a conductive layer on an entire surface of the substrate; patterning the conductive layer to form source and drain electrodes and defining a channel region; forming a passivation layer having a contact part on the entire surface of the substrate; and forming a pixel electrode connected with the drain electrode via the contact part on the passivation layer. An etch stopper can be used without additionally performing a masking process.
