Display device for vehicle

摘要

A display device for a vehicle according to the present invention includes a display which emits an emission display light having a polarization plane in a specific direction, an illumination light source which illuminates the display, and a phase difference plate which is disposed facing the display in a state where a fast axis is shifted by a predetermined angle with respect to the polarization plane of the emission display light emitted by the display.

主权项

1. A display device for a vehicle comprising:
a display which emits an emission display light having a polarization plane only in a horizontal direction; an illumination light source which illuminates the display; a phase difference plate, a λ/4 plate, which is disposed facing the display in a state where a fast axis is shifted by 45 degrees with respect to the polarization plane of the emission display light emitted by the display; an adjusting mechanism which variably adjusts an incident angle of a final display light incident on a windshield of the vehicle such that the final display light is incident on the windshield at Brewster's angle as the incident angle, wherein the final display light indicates a display light transmitted through the phase difference plate; and a rotating mechanism which rotates the phase difference plate at an arbitrary angle.
