Patent ID: 7884903

Claim:
A liquid crystal panel comprising: a liquid crystal cell having a pair of transparent substrates provided with a color filter having each color region of blue, green and red, and a liquid crystal layer formed by injecting a liquid crystal material between the transparent substrates; an optical compensating layer provided over the liquid crystal cell; and a light source for irradiating light; wherein the optical compensating layer is a single film of uniform thickness which exhibits wavelength dispersion canceling out retardation in the thickness direction for light of a wavelength (G) passing through a green region of the liquid crystal cell, and retardation in the thickness direction for light of a wavelength (R) passing through a red region of the liquid crystal cell; and the wavelength (G) represents a wavelength (nm) in which [luminous coefficient Y×emission spectrum of a light source] becomes the maximum in light of the light source passing through the green region of the liquid crystal cell, and the wavelength (R) represents a wavelength (nm) in which [luminous coefficient Y×emission spectrum of a light source] becomes the maximum in light of the light source passing through the red region of the liquid crystal cell.
