The liquid crystal layer in the liquid crystal device is set to have a refractive index anisotropy and a layer thickness giving a retardation under voltage application which is in an optimum retardation range determined based on an arrangement of the polarizer and a wavelength of light passing through the liquid crystal layer, thus improving a resultant transmittance.
