Abstract
Below a transparent pixel electrode, an opaque pixel electrode is arranged while sandwiching an insulation film between the transparent pixel electrode and the opaque pixel electrode. A common electrode is arranged below the opaque pixel electrode thus forming a holding capacitance between the common electrode and an opaque metal electrode. In case when the pixel is divided into four or more portions, an interval between the pixel electrode and the common electrode is set to an unequal pitch size or an unequal electrode width within one pixel.
Claims2
An active matrix type liquid crystal display device including a liquid crystal layer sandwiched between a transparent first substrate and a transparent second substrate, wherein
- a plurality of gate lines and a plurality of drain lines which intersect the plurality of gate lines in a matrix array are formed over the first substrate,
- a pixel region is defined in a region surrounded by the plurality of gate lines and the plurality of drain lines, and
- the pixel region includes a common electrode, a TFT element and a pixel electrode, wherein
- the common electrode is formed over the gate line and the drain line by way of an insulation film, the common electrode is wider than the gate line and the drain line,
- the pixel electrode is formed over the same layer as the common electrode and is formed of a transparent conductive body having a width narrower than a width of the common electrode, and
- ends of the pixel electrode are shielded from light by a metal electrodes and the metal electrode is arranged in a lower layer of the insulation film and an electric potential of the metal electrode is the same as an electric potential of the pixel electrode.
