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 () capable of transmitting light projected from backward, a light source () 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 (), and a stripe-patterned filter () arranged between the liquid-crystal display panel () and the light source () 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 () for emitting red, green and blue lights, to sequentially emit red, green and blue lights from the light emitters (). Images, corresponding to respective colors, are sequentially displayed on the liquid-crystal display panel () correspondingly to emission timing of the respective colors of light by the light emitters ().
