Patent ID: 8531378

Claim:
A liquid crystal display, comprising: a back light emitting monochromatic light; a liquid crystal display element comprising a pair of opposing substrates, a nematic liquid crystal layer placed between the pair of opposing substrates, an electrode pattern formed on a nematic liquid crystal layer side of each substrate, and a pair of polarizers placed outside the pair of substrates; and a controller which controls light emission of the back light and a voltage applied to the liquid crystal display element, wherein the controller controls to restrain change in retardation of the liquid crystal display element by lowering a non-selection voltage applied to the liquid crystal display element when an environmental temperature increases and by increasing the non-selection voltage applied to the liquid crystal display element when the environmental temperature decreases; and wherein retardation of the liquid crystal display element is set to match a wavelength at which a minimum transmission rate of the liquid crystal display element when no voltage is applied with a light emitting peak wavelength of the back light in a reference state in which an environmental temperature is 10 to 40 degrees Celsius lower than liquid crystal phase-isotropic phase transition temperature.
