Abstract:
1. A liquid crystal display device, comprising: a first substrate; a second substrate; a gate line and a data line on the first substrate to define a pixel region; a pixel transistor formed at the intersection of the gate line and the data line; a pixel electrode formed in the pixel region; a first storage capacitor connected to the pixel electrode; a switching line formed on the first substrate; a read out line formed on the first substrate; a second storage capacitor formed on the first substrate, directly connected to the switching line, the second storage capacitor including: a switching transistor, including: a first column spacer formed on the second substrate; and a common electrode formed on the first column spacer forming a sensing capacitor between the common electrode and an end of the second storage capacitor, the sensing capacitor including a passivation film directly contacting the data metal pattern, wherein the second storage capacitor and the sensing capacitor are connected in series between the switching line and the common electrode.
