ABSTRACT:
Transmittance and contrast of a liquid crystal display device according to FFS method are improved. A plurality of picture elements, each made of an R pixel, a G pixel and a B pixel, is disposed in a matrix form. In each of the pixels, a gate signal line extends in a left to right direction and a display signal line extends in a top to bottom direction so as to cross the gate line. A thin film transistor for pixel selection is disposed around an intersection of the gate line and the display signal line. There is provided a pixel electrode connected with the thin film transistor. A common electrode is provided on the pixel electrode through an insulation film. A plurality of slits having edges at borders between the picture elements is disposed in the common electrode to cross each of the picture elements in the left to right direction.
