Abstract
This image display apparatus includes laser beam source portions, a synthesized beam generation portion, a control portion, a branching unit, and a detection portion, while the branching unit has a reflectance or transmittance with increase/decrease characteristics opposite to increase/decrease characteristics of the outputs of laser beams in increasing or decreasing the outputs of the laser beams of color components according to changes of the wavelengths of the laser beams of the color components in order to maintain the prescribed color state of a synthesized beam.
