摘要:
A projection-type image display device includes an image light generator configured to generate image light, a projection optics configured to project the image light onto a screen. The projection optics includes a s reflection mirror configured to reflect the image light toward the screen, the image light outputted from the image light generator. A projection-type image display device includes a protective cover provided on an optical path of the image light reflected by the reflection mirror. The protective cover has a transmissive region transmitting the image light reflected by the reflection mirror.
