Abstract
In an image generation unit, a light emitting part is formed using a self-emitting OLED device, and thereby, high-contrast images can be formed and the life of the light emitting part and the life of the virtual image display apparatus are extended. Even when the light emitted in the light emitting part has deviation in color balance, a half-mirror layer that has light transmissivity and realizes see-through vision is a reflection film having wavelength dependence, and thereby, a uniform color balance of image lights is achieved and images in good conditions are visually recognized.
