Liquid crystal display device

A liquid crystal display device comprising:

• a liquid crystal display cell comprising:
• an array substrate having a pixel electrode for each color of red, green, and blue arranged on the display screen in a matrix form,
• an opposing substrate having an opposing electrode arranged in such a manner as to face the pixel electrodes of the array substrate,
• an alignment layer formed on the pixel electrode and the opposing electrode,
• 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 substrates, 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;
• a phase difference plate arranged on at least one of main surfaces of the liquid crystal display cell;
• a pair of polarization plates arranged so as to interpose the liquid crystal display cell and the phase difference plate in the crossed-Nicol configuration;
• and
• a voltage supplying source supplying the voltage applied to the blue pixel electrode in black display being different from the voltages applied to the red and green pixel electrodes in black display, and the maximum voltage of the blue pixel electrode being set to a voltage making the Z value of the XYZ stimulus value become the minimum.
