Liquid crystal display having a drain electrode with a plurality of protrusions and a fabrication method thereof

Abstract

A method of fabricating a liquid crystal display device includes the steps of forming a gate electrode on a transparent substrate; forming a gate insulating film, an active layer and an ohmic contact layer on the transparent substrate to cover the gate electrode; forming a source electrode and a drain electrode on the ohmic contact layer and patterning the drain electrode to form an L-shaped portion and a plurality of protrusions; forming a protective layer on the source and drain electrodes such that side surfaces of the protective layer, the drain electrode, the ohmic contact layer and the active layer are exposed; and forming a pixel electrode on the protective layer to electrically contact the side surface of the drain electrode.
