Abstract:
1. A liquid crystal display device comprising: an array substrate having pixel electrodes for each color of red, green and blue arranged in a matrix form; an opposing substrate having opposing electrodes arranged in such a manner as to face the pixel electrodes of the array substrate; a liquid crystal layer arranged in a bend alignment interposed between the array substrate and the opposing substrate; and a filter comprising a red filter layer, a green filter layer and a blue filter layer provided on one side of the substrate, the red filter layer being arranged corresponding to the red pixel electrode, the green filter layer being arranged corresponding to the green pixel electrode, and the blue filter layer being arranged corresponding to the blue pixel electrode, wherein a gap distance between the blue pixel electrode and the opposing electrode is different from a gap distance between the red pixel electrode and the opposing electrode, and also different from a gap distance between the green pixel electrode and the opposing electrode, and satisfies followings: where the gap distance between the blue pixel electrode and the opposing electrode is represented by dB; the gap distance between the red pixel electrode and the opposing electrode is represented by dR; and the gap distance between the green pixel electrode and the opposing electrode is represented by dG, and wherein either the dR or the dG is larger than a gap distance which minimizes the brightness ratio at the viewing angle of 60 degrees to the right.
