Abstract
The purpose of the present invention is to efficiently orient image light toward an observer. A display device outputs projection light for displaying an image. A transmission type screen forms an image of the projection light and diffuses the same as image light. A projection lens enlarges projection light and forms the image on the transmission type screen. A light distribution adjustment means is disposed between the transmission type screen and the projection lens and adjusts the light distribution of the image light output by the transmission type screen for each region by refracting the projection light.
