Image display device and display device |
| abstract |
The present invention provides an image display device that constitutes a display device such as a retinal projection HMD having a configuration and a structure that can achieve reduction in size and weight. An image display apparatus 10 receives an image emitted from an image forming apparatus 21 disposed outside (outside the system), and splits the image into a plurality of images. The focusing device 12 is provided to focus the plurality of images emitted from the light branching device 11 onto the pupil 32 of the observer 31, and the focal length of the focusing device 12 is F 0 (unit: mm). When the optical distance from the light branching element 11 to the condensing element 12 is L 0 (unit: mm), L 0 = F 0 ± 10 is satisfied. [Selected figure] Figure 1 |
