Abstract
A projection-type display apparatus has a light modulator for emitting a zero-order diffracted beam and a first-order diffracted beam which are added by a prism into a projecting light beam which is introduced into a light beam scanning system, which two-dimensionally scans a screen. The maximum intensity of the projecting light beam is increased to increase the brightness of the overall screen.
