Abstract:
1. A luminous display device comprising: a reflecting member arranged with an inclination from being perpendicular to a line of sight, said line of sight being from an eye point of a viewer to a virtual image; a liquid crystal display arranged with an inclination to the line of sight as reflected by the reflecting member; a backlight; and a focusing lens member arranged between the backlight and the liquid crystal display, wherein illumination light from the backlight is irradiated from the rear of the liquid crystal display and light of a display image displayed on the liquid crystal display is emitted toward the reflecting member, so that the virtual image being seen on the reflecting member is image-formed on a plane perpendicular to the line of sight, wherein the backlight is arranged in such a manner that a luminous surface of the backlight is perpendicular to the line of sight as reflected by the reflecting member, wherein the focusing lens member focuses beams of the illumination light in such a manner that the beams of the illumination light emitted from the luminous surface of the backlight stay inside the reflecting member and that the beams of the illumination light, which pass through the liquid crystal display to become the light of a display image, stay inside the reflecting member.
