摘要:
The present invention provides a liquid crystal display device of a transverse electric field mode that may inhibit internal reflection and realize proper black display to which coloring does not occur. The present invention provides a liquid crystal display device including a first linear polarizer, a first λ/4 retardation layer, a first substrate, a second λ/4 retardation layer configured with a different material from the first λ/4 retardation layer, a liquid crystal layer that contains liquid crystals which are horizontally aligned in a case where no voltage is applied, plural electrode pairs that generate a transverse electric field in the liquid crystal layer by a voltage being applied, a second substrate, a second linear polarizer, and a backlight. In a case where a color of light emitted from the backlight is expressed by using chromaticity coordinates (x, y) of an XYZ color system, both of x and y are 0.32 or greater. The plural electrode pairs include a red electrode pair arranged in a red sub-pixel, a green electrode pair arranged in a green sub-pixel, and a blue electrode pair arranged in a blue sub-pixel. A white display applied voltage of the blue electrode pair is different from the white display applied voltage of the red electrode pair and the white display applied voltage of the green electrode pair.
