PURPOSE: An image projecting device in which relay lenses are omitted is provided to enable to reduce a size of the image projecting device because the number of part arranged along a longitudinal direction is reduced. CONSTITUTION: An image projecting device(100) comprises a lighting unit(110), a first prism(130), a reflection mirror(140), an image forming unit(150), and a second prism(160). The lighting unit generates lights. The first prism receives the lights, thereby totally reflecting the same. The reflection mirror receives the lights totally reflected from the first prism, thereby reflecting the same. The image forming unit generates image by using the lights reflected by the reflection mirror. The second prism totally reflects the images generated by the image forming unit to a screen(180). |
