Abstract:
1. An image display apparatus for displaying an image on a projection surface by applying laser beams of three colors to said projection surface, comprising: a single-wavelength laser emitting a laser beam of one color of said three colors; a two-wavelength laser having laser elements respectively emitting laser beams of two colors of said three colors, the laser elements being contained in a single package; a synthesizing element causing an optical path of said laser beam of one color and respective optical paths of said laser beams of two colors to coincide with each other; and a scan device selectively applying said laser beams of three colors transmitted through said synthesizing element to said projection surface pixel by pixel of said image, wherein the synthesizing element comprises a single surface that reflects almost all light from each of the laser elements of the two-wavelength laser, and that allows almost all light from the single-wavelength laser to pass through.
