Abstract:
1. A liquid crystal device, comprising: a liquid crystal layer sealed between a pair of substrates of a liquid crystal panel including the pair of substrates arranged to face each other; a first polarizer that converts incident light into a circularly polarized component in one rotary direction to emit to the liquid crystal panel, the first polarizer facing an incidence surface of the liquid crystal panel and having a birefringence characteristic that is set based on a peak wavelength of incident light, the first polarizer including a first linear polarizer and a first quarter-wavelength retardation plate, the first quarter-wavelength retardation plate having a phase shift amount, a product of four times the phase shift amount being substantially the same as the peak wavelength of the incident light; and a second polarizer that transmits a circularly polarized component in another rotary direction of the light which passed through the liquid crystal panel, the second polarizers facing an exit surface of the liquid crystal panel and having a birefringence characteristic based on a peak wavelength of the incident light, the second polarizer including a second linear polarizer and a second quarter-wavelength retardation plate, the second quarter-wavelength retardation plate having a phase shift amount, a product of four times the phase shift amount being substantially the same as the peak wavelength of the incident light.
