ABSTRACT:
A method is provided for manufacturing a liquid crystal display having a gate bus line, a data bus line, and a switching element with a drain electrode over a substrate. The method includes the steps of forming a protection layer over the substrate to cover the gate bus line, the data bus line and the switching element, roughening the surface of the protection layer, removing a portion of the protection layer to define a contact hole in the protection layer over the drain electrode of the switching element, and forming a pixel electrode on the roughened surface of the protection layer, the pixel electrode being connected to the drain electrode through the contact hole.
