ABSTRACT:
A method for fabricating a LCD having enhanced aperture ratio and brightness includes: forming a gate line, a gate electrode, a common electrode and a common line in a first mask process; depositing a gate insulating layer covering the gate line, the gate electrode and the common electrode; forming an active layer on the gate insulating layer, and an ohmic contact layer on the active layer in a second mask process; forming a data line, a source electrode, and a drain electrode facing the source electrode in a third mask process; depositing a protective layer over the data line, the source electrode and the drain electrode; forming a pixel contact hole in a fourth mask process; and forming a pixel electrode, wherein the pixel electrode is connected to the drain electrode through the pixel contact hole in a fifth mask process using a reverse tapered photo-resist pattern.
