Abstract:
1. A liquid crystal display device comprising: a pair of substrates which is arranged to face each other in an opposed manner with liquid crystal sandwiched therebetween; light blocking films and color filters formed on one substrate of the pair of substrates; red sub pixels, green sub pixels, and blue sub pixels determined based on colors of the color filters; and drain signal lines, thin film transistors, and pixel electrodes formed on an other substrate of the pair of substrates; wherein drain electrodes of the thin film transistors are connected to the drain signal lines, and the pixel electrodes are connected to the thin film transistors; wherein the red sub pixels, the green sub pixels and the blue sub pixels are arranged in a first direction; wherein the light blocking films are overlapped with the drain signal lines, and arranged on a boundary portion between the red sub pixel and the green sub pixel arranged adjacent to each other, on a boundary portion between the green sub pixel and the blue sub pixel arranged adjacent to each other, and on a boundary portion between the blue sub pixel and the red sub pixel arranged adjacent to each other; and wherein a width of the light blocking film arranged on the boundary portion between the blue sub pixel and the sub pixel of a color other than a blue color and disposed between the pixel electrodes in the first direction is set larger than a width of the light blocking film arranged on the boundary portion between the red sub pixel and the green sub pixel and disposed between the pixel electrodes in the first direction.
