Abstract
A projection display device includes a condensing unit and a shading unit. The condensing unit condenses light emitted from a light source to form a condensed spot on a color wheel. The shading unit, when a size of the condensed spot on the color wheel has increased due to an increase in light emission of the light source, shades a portion of the light passing through the color wheel corresponding to the increased size.
