Abstract:
1. A liquid crystal display device, comprising: a gate line, a gate electrode, a gate pad electrode at an end of the gate line, and a common line on a substrate; a gate insulating layer on the gate electrode; an active layer on the gate insulating layer; an etch stopper on the active layer; first and second ohmic contact layers spaced apart from each other on the active layer and an impurity-doped amorphous silicon pattern contacting the gate insulating layer therebelow, outer sides of the first and second ohmic contact layers being outside the active layer; a data line crossing the gate line to define a pixel region, a data pad electrode at an end of the data line, and source and drain electrodes on the first and second ohmic contact layers, respectively; a pixel electrode and a common electrode in the pixel region to induce an in-plane electric field; and a gate pad terminal electrode on the gate pad electrode, wherein each of the data line, the pixel electrode and the common electrode contacts the impurity-doped amorphous silicon pattern therebelow.
