Abstract:
1. A liquid crystal display device comprising: first and second electrode substrates; a liquid crystal layer held between the first and second electrode substrates and including liquid crystal molecules that are aligned substantially in parallel without twist; first and second retardation plates that are disposed on the first and second electrode substrates on sides opposed to the liquid crystal layer; first and second polarizing plates disposed on the first and second retardation plates; and a color filter disposed in one of the first and second electrode substrates; wherein the second electrode substrate includes a light transmissive section that passes backlight coming in from the second polarizing plate side, the first and second retardation plates have slow axes that are parallel or perpendicular to the alignment direction of the liquid crystal molecules, and a product of a refractive anisotropy Δn of the liquid crystal layer and a thickness d of the liquid crystal layer, a retardation R wherein chromaticity coordinates (x, y) of transmitted light, when the backlight passes through the color filter layer, are within ranges of 0.290≦x≦0.310, and 0.280≦y≦0.300.
