Document Type and Number:
WIPO Patent Application WO/2021/193614
Kind Code:
A1
Abstract:
This head-up display is provided with: a polarizing member (18) including a first supporting plate (30) and a second supporting plate (38) that are provided on a polarizing plate (34); a display (12) that outputs an image including a linear polarization component; and a housing (10) that houses the display (12). The polarizing member (18) is used as a light transmissive cover through which the image is transmitted to the outside of the housing (10). The angle formed by the transmission axis of the polarizing plate (34) and the polarizing direction of the image outputted from the display (12) is set in a relationship except parallel and orthogonal angles, and the image transmitted through the polarizing member (18) projects, as a projection image, a virtual image containing polarized light in a horizontal direction and a vertical direction.
