Abstract
A projection-type display device includes: R, G, and B light sources that emit light beams with different colors; a projection unit that projects light beams based on image information among light beams emitted from the light sources onto a projection screen; a heat sink that radiates heat generated from the R light source, which has a maximum change in light emission intensity relative to a change in temperature, among the light sources; and a heat sink that radiates heat generated from the G and B light sources and that has a surface area smaller than that of the heat sink. In a use state, the R light source is disposed on a side apart from the other light sources in a direction opposite to a direction of gravitational force.
