るプロジエクター。 A light source that emits light; a color separation unit that separates the light into green, red, and blue light; a light guide path configured by two reflective mirrors; a light valve that adjusts the amount of transmission of the green, red, and blue light; In a projector that consists of a color combining section that combines the light transmitted through a light bulb and a projection lens that projects the combined light, the reflection near the color separation section of two reflective mirrors arranged in the light guide path. The mirror is placed closer to the optical axis of the projection lens than the reflective mirror that is close to the color combining section, and the reflective mirror that is close to the color combining section is attached at an angle of 45 degrees or less with the optical axis of the projection lens. projector.
