PURPOSE:To prevent a bright spot from appearing on a screen. CONSTITUTION:A projection part 26 is fitted on one side of the bottom surface of a liquid crystal display unit 18 and a liquid crystal panel 19 slants to a mirror Fresnel lens 12. The image of a light source 15 projected on the surface of the liquid crystal panel 19 is reflected by the liquid crystal panel 19 and reaches a place off a projection lens 16. Therefore, the reflected image of the light source 15 on the surface of the liquid crystal panel never appears as a bright spot on the screen. |
