摘要： The amorphous silicon layer overlaps the gate electrode and the edges of the amorphous silicon layer are substantially encompassed by the edges of the gate electrode. The distance between the edges is at least 2 microns. Accordingly, both the light obliquely incident on the amorphous silicon layer from the outside once the light normally incident on the amorphous silicon layer is blocked by the gate electrode. Insulation layers, which are separated from the amorphous silicon layer and made of an amorphous silicon, are interposed between the edges of the source/drain electrodes and the gate electrode to reinforce the insulation between the gate electrode and the source/drain electrodes and also to absorb the light reflected by the source/drain electrodes and the gate electrode. The source electrode may partially surround the drain electrode in annular shape, to reduce the parasitic capacitance generated between the gate electrode and the drain electrode. The amorphous silicon layer may protrude out the gate electrode near the edges of the gate electrode which encompasses a source electrode and the source/drain electrodes. The amorphous silicon layer covers the edges of the gate electrode which encompasses the source electrode. The source electrode may be curved to prolong the distance between the drain electrode and the portion of the amorphous silicon layer.

摘要： A liquid crystal display (LCD) device includes a first substrate, a second substrate spaced apart from the first substrate and a liquid crystal layer interposed between the substrates. A sensing controlling section is also included in the LCD device. The second substrate includes a sensing array that senses a change in a sensing voltage responsive to a change in a thickness of the liquid crystal layer. The sensing controlling section detects a touch position data by comparing a reference voltage that changes according to a change in temperature with a variation voltage that corresponds to a difference between the sensing voltage and an initial voltage corresponding to an initial thickness of the untouched liquid crystal layer.
