摘要:
A stereoscopic image display apparatus includes: a plane display device; a lens array provided in front of the display surface to distribute light rays from pixels of the display device to predetermined angles, and having a plurality of lenses arranged in a first direction; a variable polarizer provided between the plane display device and the lens array to polarize light rays from the pixels; and a double refraction prism array provided on an opposite side of the lens array from the display device, and including a plurality of double refraction prisms. Each of the double refraction prisms has a ridge in a second direction perpendicular to the first direction and arranged in the first direction with a pitch which is substantially twice a lens pitch in the lens array, and has double refraction in which a refractive index in a ridge direction is different from a refractive index in a direction perpendicular to the ridge direction.
