Abstract:
1. An LCD device comprising: a first substrate with a plurality of pixel regions defined by gate lines and data lines; an active layer in each pixel region of the first substrate; a gate pattern including a plurality of gate electrodes, a portion of the gate electrodes overlapping with a predetermined portion of the active layer with an insulating layer interposed in-between; a plurality of channel regions in the areas of the active layer overlapped with the plurality of gate electrodes; a plurality of lightly doped drain regions in the active layer and directly adjacent to the plurality of channel regions; a data electrode electrically connected to the active layer; a first passivation layer to cover the data electrode; a common electrode on the first passivation layer; a conductive line on the common electrode; a first contact hole formed by etching a predetermined portion of the first passivation layer, the first contact hole for exposing the data electrode; a common via inside the first contact hole; a conductive via inside the first contact hole, wherein the conductive via is formed on the common via; a second passivation layer on the common electrode and the conductive line; a second contact hole formed by etching a predetermined portion of the second passivation layer, the second contact hole for exposing the conductive via corresponding to the data electrode; and a pixel electrode on the second passivation layer and inside the second contact hole, the pixel electrode electrically connected with the conductive via.
