Patent ID: 7450210

Claim:
A thin film transistor (TFT) active matrix type 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 scanning signal lines formed over the first substrate; an insulating film formed over the first substrate and the plurality of scanning signal lines; a plurality of image signal lines formed over the insulating film; a plurality of pixel regions, each of the plurality of the pixel regions being surrounded by two adjacent scanning signal lines of the plurality of scanning signal lines and two adjacent image signal lines of the plurality of image signal lines; and a common transparent electrode formed over the second substrate, wherein the plurality of image signal lines are extending in a first direction and the plurality of scanning signal lines are extending in a second direction, perpendicular to the first direction, with respect to a plan view of an arrangement of the pixel regions, wherein each of the plurality of pixel regions contains a first divided pixel electrode comprising a first edge line, a second divided pixel electrode comprising a second edge line and a third edge line, and a third divided pixel electrode comprising a fourth edge line, and these divided pixel electrodes are supplied with an image signal from one of the two adjacent image signal lines, the first edge line, the second edge line, the third edge line and the fourth edge line are inclined to the plurality of scanning signal lines, and there are formed a first area of space between the first edge line and the second edge line and a second area of space between the third edge line and the fourth edge line, and the first divided pixel electrode and the second divided pixel electrode, which are divided by the first area of space, are arranged along the first direction.
