Abstract
A head mounted display uses an image projection device comprising: an image generation unit for generating an image; a projection unit for guiding the image generated by the image generation unit to an observer's eyes; and a support for linking the projection unit and the image generation unit. The projection unit has a lens function which makes it easiest to see an image generated by the projection unit at a distance (Lobj) within a range between 30 cm and 3 m. Thereby, the image projection device operates at high resolution, has reduced size and weight, and reduces energy consumption.
