DISPLAY DEVICE
Document Type and Number:
Japanese Patent JPH11305640
Kind Code:

Abstract:

To provide a display device permitting a multi-color display of contents to be displayed by using fundamentally a single light source.

This display equipment 11 is provided with a hologram plate 13 with which plural predetermined images are individually recorded in each recording part, a light source 17 for irradiating predetermined lighting light 15 as reproduction lighting light, an optical control element 19 for shielding or unshielding the lighting light 15 incident on each recording part of the hologram plate, and a control part 21 for controlling the light source 17 and an optical control element 19. The lighting light 15 is light with plural peak wavelengths distributed discontinuously, and by making this lighting light 15 onto the hologram plate 13 according to predetermined conditions, the light Li1 or Lin differing in color from each other is emitted as reproduced light from each recording part of the hologram plate 13 in a striped pattern distributed, and a multi-color display is achieved by the light by which each image is distributed in a striped pattern of mutually different color. For the optical control element 19, for example, a liquid-crystal element using polymer dispersed liquid crystal layer is used.
