ABSTRACT:
A laser display device, which is capable of ensuring the safety of a person's eyes and reducing speckle noise even when a screen is arranged at an arbitrary position, includes a laser light source emitting a laser light, a modulator modulating the laser light and emitting a modulated light, and a branching unit branching the modulated light into a plurality of branched lights. Further, at least two of the plurality of branched lights reach same positions on a screen at substantially same timings.
