Abstract:
1. A method of fabricating a liquid crystal display device, comprising: providing first and second substrates; a first mask process of forming a gate line and a gate electrode connected to the gate line on the first substrate; a second mask process including forming a gate insulating film on the gate line and the gate electrode and forming a semiconductor layer, then defining a pixel hole that passes through the gate insulating film and the semiconductor layer in a pixel area, and forming a pixel electrode in the pixel hole; and a third mask process including forming a source and drain metal pattern having a data line crossing the gate line to define the pixel area, a source electrode and a drain electrode on the first substrate, and exposing an active layer of the semiconductor pattern to define a channel between the source electrode and the drain electrode, wherein the first mask process further includes forming a lower pad electrode connected to the gate line; and wherein the second mask process further includes forming a contact hole to expose the lower pad electrode and forming an upper pad electrode connected to the lower pad electrode in the contact hole.
