Abstract
According to an aspect, a head-up display includes: a liquid crystal display device configured to emit first light corresponding to a first image from a display surface toward a light-transmitting body in a first emission direction and to emit second light corresponding to a second image from the display surface in a second emission direction different from the first emission direction; and a reflective plate having a reflection surface on which the second light is incident and that reflects the second light toward the light-transmitting body in the first emission direction.
Claims4
A head-up display comprising:
- a liquid crystal display device configured to emit first light corresponding to a first image from a display surface toward a light-transmitting body in a first emission direction and to emit second light corresponding to a second image from the display surface in a second emission direction different from the first emission direction;
- and
- a reflective plate having a reflection surface on which the second light is incident and that reflects the second light toward the light-transmitting body in the first emission direction.
A head-up display comprising:
- a liquid crystal display device configured to emit first light corresponding to a first image from a display surface toward a light-transmitting body in a first emission direction and to emit second light corresponding to a second image from the display surface in a second emission direction different from the first emission direction;
- a 1/4 wave plate on which the second light emitted from the display surface is incident;
- and
- a reflective plate having a reflection surface that reflects light transmitted through the 1/4 wave plate, in the second emission direction toward the display surface through the 1/4 wave plate, wherein
- a first angle between a direction orthogonal to the display surface and the first emission direction is equal to a second angle between the orthogonal direction and the second emission direction, and
- the liquid crystal display device includes a reflective polarizing plate configured to pass linearly polarized light having a first polarization direction and to reflect linearly polarized light having a second polarization direction orthogonal to the first polarization direction.
