PURPOSE: A laser display device is provided to minimize scintillation and speckles by reducing a coherence characteristic of a laser beam and reduce loss of the intensity of radiation, thereby improving the picture quality. CONSTITUTION: R, G, and B lasers(41) output R, G, and B beams. A color wheel(31) divides a white beam formed by composing the R, G, and B beams into the R, G, and B beams in order. A plurality of micro-lens arrays(33) are placed at a rear surface of the color wheel, let the R, G, and B beams incident for focusing the beams emitted from the R, G, and B lasers, and emit the beams at a predetermined angle. A load lens lets the beam emitted from the micro-lens arrays incident and totally reflects the beams for equally mixing the laser beams. A DMD(Digital Micromirror Display) panel(45) inputs the R, G, and B beams in a time scaling and outputs the corresponding image according to a video signal.
