MIRROR UNIT AND DISPLAY DEVICE
First Claim
1. A mirror unit configured to be installed on a vehicle, comprising:
- a mirror element configured to reflect external light entering from a front surface toward the front surface; and
a display device configured to show an image,wherein the display device comprises;
a light source configured to emit light, anda light guide element configured to guide incident light from the light source,wherein the light guide element comprises;
an emission surface configured to output incident light, anda plurality of light focusing portions configured to change the path of the incident light toward the emission surface, causing the light output to converge toward a convergence point or convergence line outside the light guide element or to radiate from a convergence point or convergence line outside the light guide element and thereby form an image outside the light guide element, andwherein the mirror element and the light guide element are arranged so that the light focusing portions form an image near the front surface of the mirror element.

Abstract
A mirror unit includes a mirror element configured to reflect external light entering from a front surface toward the front surface, and a display device configured to show an image. The display device includes a light source configured to emit light, and a light guide element configured to guide incident light from the light source. The light guide element includes an emission surface configured to output incident light, and a plurality of light focusing portions configured to form an image outside the light guide element. The mirror element and the light guide element arranged so that the light focusing portions form an image near the front surface of the mirror element.

4. A mirror unit configured to be installed on a vehicle, comprising:
-
a display device configured to show an image, comprising; a light source configured to emit light; and a panel-like light guide element configured to guide incident light from the light source, and comprising; an emission surface configured to output incident light, and a plurality of light focusing portions configured to change the path of the incident light toward the emission surface, causing the light output to converge toward a convergence point or convergence line outside the light guide element or to radiate from a convergence point or convergence line outside the light guide element and thereby form an image outside the light guide element; and a reflective layer formed on the surface facing the emission surface of the light guide element and configured to reflect external light entering from the emission surface and passing through the light guide element toward the emission surface. - View Dependent Claims (15, 19)
