    摘要： There is provided a device capable of switching between a state that displays a high-quality image and a mirror status in which is obtained an easy-to-view reflection image suitable for a person to view his/her own face or figure. An image display portion 1000 that emits image light 3001, reflective polarization selection means 300 that transmits a first linear polarization component emitted from the image display portion 1000 and reflects a second linear polarization component, whose polarization axis is orthogonal to that of the first linear polarization component, a transmission polarization axis variable portion 400 capable of selecting between one of a state that changes the polarization axis of incident linearly polarized light and a state that does not change the polarization axis of incident linearly polarized light, and a polarization selection member 500 which, of the incident light, absorbs the first linear polarization component and transmits the second linear polarization component, whose polarization axis is orthogonal to that of the first linear polarization component, are disposed in this order. In this case, absorbing polarization selection means 208 is disposed at the image display portion 1000, and the first linear polarization is emitted as the image light.

    摘要： An illumination apparatus provides an improved light utilization efficiency and improved collimation. The illumination apparatus has a light guide, a collimating unit provided at least on one side of the light guide for collimating rays incident on the light guide, and a light source disposed in the vicinity of the collimating unit and surrounded by a reflector. Preferably, in order for the light guide to be able to emit collimated light uniformly from its emission surface, the light guide has inclined reflecting irregularities or stepwise reflecting plates which are provided directly or via an air gap on a back surface opposite to the emission surface thereof, wherein the inclined reflecting plates are specular-finished at least on the inclined portions.
