Title:
PROJECTOR FOR HEAD-UP DISPLAY
Document Type and Number:
WIPO Patent Application WO/2021/060402
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a projector for a head-up display, the projector using a reflection member having a selective reflection layer, and being such that it is possible to suppress any decrease in the luminance of a projected video and the disruption of color balance of the projected video even when the wavelength of a light beam fluctuates. The problem is solved by having: a light source for forming a projected video; and a reflection member having a selective reflection layer that reflects visible light and is composed of two or more layers mutually differing terms of in the center wavelength of selective reflection, and an interference suppression layer having a thickness of 10 μm or greater, the reflection member being configured so that the interference suppression layer is located closer to the side at which light from the light source impinges than is the selective reflection layer.
