Patent ID: 7972880

Claim:
A method for fabricating a liquid crystal display device, comprising: forming a gate line and a gate pad at the end of gate line, a gate electrode connected to the gate line, a common electrode and a common line connected to the common electrode on a substrate in a first mask process; depositing a gate insulating layer on the substrate to cover the gate line, the gate electrode and the common electrode; forming an active layer on the gate insulating layer, the active layer overlapping the gate electrode to form a channel layer, and forming an ohmic contact layer on the active layer in a second mask process; forming a data line crossing the gate line to define a pixel region, a data pad at an end of the data line, a source electrode connected to the data line, 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 that exposes the drain electrode by penetrating the protective layer in a fourth mask process; and forming a pixel electrode that generates a horizontal electric field with the common electrode in the pixel region, 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 wherein at least one of the pixel electrode, common electrode, the gate line, the data line and the common line, the gate electrode, the source electrode, the drain electrode has a line width of about 1.5.about.4.0.mu.m.
