Projector having a first light separation optical system and a second light separation optical system

摘要

A projector includes a light source, a first light separation optical system adapted to separate light emitted from the light source into first light and second light, a second light separation optical system adapted to separate the first light into third light and fourth light, separate the second light into fifth light and sixth light, and emit the third light, the fourth light, the fifth light, and the six light in directions intersecting with a plane including a light axis of the light emitted from the light source and a light axis of the first light, and a light modulation element which the third light, the fourth light, the fifth light, and the sixth light enter.
