Provided is a laser display apparatus in which speckle can be suppressed. The laser display apparatus includes: a laser comprising a first mirror and a second mirror that are separated by a cavity distance and form a cavity; and a spatial modulator modulating light transmitted through the first mirror of the laser to display an image on a screen, wherein, when a coherence length l.sub.c and an effective reflectivity R are defined by the following equation:.times..times..times..pi..times..times..times. ##EQU00001## where d is the cavity distance of the laser, R.sub.1 is the reflectivity of the first mirror, and R.sub.2 is the reflectivity of the second mirror, the coherence length l.sub.c satisfies the following inequality: 0
