Projection display device |
摘要 |
In a projection display device that is provided with a relay lens for converting flux that is emitted from a light source to a parallel flux for illuminating an image display element (DMD), and a total internal reflection prism for both directing flux that is emitted from the relay lens to the DMD and directing flux that is reflected by the DMD toward a projection lens, the relay lens is unified with the prism as a lens-integral prism by bonding the relay lens to the total internal reflection surface of the prism.
