Zusammenfassung:There is disclosed a laser projection display including a light source unit for emitting light laser light; a light resolution unit for resolving the laser light into a first light and a second light; an optical scanner for realizing an image by scanning the resolved first light to a screen; a sensing unit for sensing the resolved second light; and an alignment compensation unit for calculating location variation of the second light sensed by the sensing unit and compensating color alignment to correspond to the calculated location variation value, wherein a distance between a light emitting surface of the light resolution and a light incidence surface of the optical scanner is equal to a distance between a light emitting surface of the light resolution unit and a light incidence surface of the sensing unit.
