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).

Abstract: The invention is intended to change the viewing angle in accordance with a viewer's intention. Disposed between a light source (810) and a liquid crystal display panel (804), a Fresnel lens (812) converts light coming from the light source (810) to approximately parallel light and allows plural images to be displayed to different positions. The light source (810) is configured in such a manner that lighting positions and lighting regions can be changed. Lighting control means for changing the lighting positions or lighted regions of the light sources (810) is provided.

Abstract: The present invention is intended to improve assembleability of a portion of a liquid crystal display panel. In an image display system for displaying images by allowing a light irradiated from behind to be transmitted therethrough, a liquid crystal display panel unit (227) includes a liquid crystal display panel (252) having a polarizing plate (251) at least on the back surface thereof and a micro-patterned retarder (253) mounted to the rear surface of the polarizing plate (251) on the back surface of the liquid crystal display panel (252), and the liquid crystal display panel unit (227) and a diffuser panel (226) to be disposed in front thereof can be supported in the depressed state in the fore-and-aft direction by an upright wall (262) of a mounting base member (223) defining an opening section (260) in an area including the polarizing plates (250, 251) of the liquid crystal display panel (252).

Abstract: An image display in which, even when an observer moves vertically in a position viewing an image, a bright image is obtained. There are provided a liquid-crystal display panel (804) capable of transmitting light projected from backward, a light source (801) for projecting a first light as a particular polarization of light and a second light orthogonal in polarization axis to the first light to the liquid-crystal display panel (804), and a stripe-patterned filter (802) arranged between the liquid-crystal display panel (804) and the light source (801) and having, repeatedly in a given direction, first areas for transmitting the first light and second areas for transmitting the second light. The light source is structured by including light emitters (810) for emitting red, green and blue lights, to sequentially emit red, green and blue lights from the light emitters (810).
