Abstract
The present invention provides an image display system that secures a bright image and reduces cross-talk of a three-dimensional image display of a liquid-crystal type and provides a large viewing angle. The image display system includes a filter having a first area for transmitting light of a specific polarization and a second area for transmitting a light of polarization axis orthogonal to the light of the specific polarization provided repeatedly in the vertical direction, and a light source (201) including a light-emitting source (210), a polarizer (212) for emitting the light in the forms of the light having the specific polarization and the light having the polarization axis orthogonal to the specific polarization, and an optical element (203) for refracting the lights having the different polarizations into the directions toward the left and right eyes respectively and irradiating the same onto a liquid crystal panel (205).
