Title:
立体画像表示装置
Document Type and Number:
Japanese Patent JP5105920
Kind Code:
B2
Abstract:
It is made possible to provide a stereoscopic image display apparatus capable of preventing the stereoscopic display characteristics from being degraded even if the locus of light rays between the lens and the two-dimensional display device becomes long. A stereoscopic image display apparatus includes: a plane display device having a display face formed of a plurality of pixels arranged in a matrix form; an optical plate comprising a plurality of lenses which are arranged in front of the display face of the plane display device and which have a uniaxial double refractive material inserted therein, and controlling light rays from the pixels; and a sheet polarizer provided between the plane display device and the optical plate to align a polarization direction of light ray. In the double refractive material, a maximum primary axis of refractive index is parallel to ridgelines of the lenses and is inclined in a direction opposed to a viewer.
