Abstract:
This head-up display that is mounted in a vehicle (1) and displays a virtual image so that the image is viewable by a passenger by projecting the image on a transmissive projection member (3) is provided with: a projector (10) that projects an image as light polarized in the direction of a polarizing axis (21); a polarizer (40) that is disposed on an optical path (OP) formed by the light of the image and has a property of transmitting light polarized along a transmission axis (41); and a phase element (50) that is disposed, on the optical path, between the polarizer and the projection member, and has a property of changing the direction of polarization of transmitted light by producing a phase difference. A fast axis direction (DF) of the phase element intersects a direction (DT) corresponding to the polarizing axis, a direction (D1) corresponding to the transmission axis, and a direction (DWS) corresponding to S polarization of the projection member.
