The present invention provides a scan-type image display device. In the scan-type image display device, laser light sources respectively generate light beams of green, red and blue, which in turn are combined by dichroic mirrors to generate a first beam and a second beam. A deflecting mirror device two-dimensionally scans the first and second beams under the rotation of a deflecting mirror thereof. The outgoing directions of the first and second beams have an angular difference relative to the vertical direction of a screen, and an interval between the first and second laser beams is set to be larger than an aperture diameter defined by laser safety standards.
