The blind spot assist device shows the image of the blind-spot zone blocked by an obstacle, and is provided with a pair of parallel plane mirrors to which light representing the image is incident, the pair of parallel plane mirrors comprising a semitransparent plane mirror and a plane mirror opposed to each other. The semitransparent plane mirror is provided on the viewer side for reflecting part of the light and transmitting part of the light. The plane mirror reflects the light to the semitransparent plane mirror.

Abstract: A display device (display unit) for vehicles has a display element emitting display light. It has a reflecting member (reflecting mirror) for reflecting the display light. It has a drive means for angularly moving the reflecting member at a first speed at ordinary times or at a second speed greater than the first speed. When an ignition switch is turned off, the drive means angularly moves the reflecting member to an angular position where the sunlight is not reflected by the display element and when the ignition switch is turned on, it angularly moves the reflecting member to an original position where the display light is visible at the second speed.

Abstract: Disclosed is a display device at a low cost which enhances the color purity of light to be projected, and which resists deterioration due to ambient light such as infrared ray. This display device includes an LED, an optical member for selectively outputting light components, of which wavelength is a predetermined minimum-limit wavelength or longer, from incident light, and a mirror for selectively reflecting light components, of which wavelength is a predetermined maximum-limit wavelength or shorter, from irradiated light. One of the optical member or the mirror receives light directly from the LED, and outputs it to the other. Subsequently, the other receives the light from one of the optical member and the mirror, and outputs it.
