Abstract:
1. A liquid crystal display device comprising: a first substrate and a second substrate; a liquid crystal layer disposed between the first substrate and the second substrate; a plurality of gate lines and a plurality of drain lines formed on the first substrate; and a plurality of pixel regions surrounded by the plurality of gate lines and the plurality of drain lines, wherein each of the plurality of pixel regions comprises a thin film transistor, a pixel electrode which is a rectangular shape in plan view, and a counter electrode which has a plurality of cutout portions, wherein the thin film transistor comprises a semiconductor layer formed on the first substrate, a gate insulator formed on the semiconductor layer, a gate electrode formed on the gate insulator and electrically connected to one of the plurality of gate lines, a first electrode electrically connected to one of the plurality of drain lines and the semiconductor layer, and a second electrode electrically connected to the pixel electrode and the semiconductor layer, wherein a insulation film is disposed between the pixel electrode and the counter electrode, and the counter electrode is formed over the pixel electrode, and wherein a part of the cutout portions of the counter electrode overlaps with a part of the semiconductor layer.
