PURPOSE: A laser display system is provided to reduce the speckle phenomenon of laser light by overlapping S or P-polarized light reached to N-1-th pixel forming time and S or P-polarized light reached to N-th pixel forming time. CONSTITUTION: A laser illuminating system radiates laser light. A polarized light separating part(200) separates S-polarized light and P-polarized light from the laser light and reflects the S-polarized light and the P-polarized light through different light paths at different time. The polarized light separating part includes a first prism with a first reflecting side(202) and a second prism with a second reflecting side(204). The first reflecting side reflects the S or P-polarized light from the laser light. The second reflecting side reflects the S or P-polarized light through the first reflecting side.
