Patent ID: 7830579

Claim:
A stereoscopic-image display apparatus comprising: an elemental-image display unit that includes pixel plane on which pixels are arranged in matrix; a polarization switching cell that is arranged opposite to the elemental-image display unit, and that switches polarization direction thereof corresponding to applied voltage; a lens array lamination layer that includes refractive-index anisotropic mediums and substrates with two lens arrays whose principal planes are different from each other, the refractive-index anisotropic mediums making lens effect of either one of the lens arrays effective corresponding to the polarization direction switched by the polarization switching cell; a synchronization drive unit that controls voltage to be applied to the polarization switching cell synchronizing with a display timing of images displayed on the elemental-image display unit, and that switches the lens array to be effective at each display timing; and a display control unit that controls the elemental-image display unit to alternately display the images on near or far sides by time division multiplexing, synchronizing with the display timing, wherein focal planes of the two lens arrays are positioned at different positions from each other near the pixel plane.
