Abstract

According to one embodiment, a projector includes a light source unit, a light scanning unit, and a focus controller. The light source unit emits laser light. The light scanning unit includes a holder and a reflective surface. The holder is capable of a first rotation operation around a first direction. The reflective surface is held by the holder and is capable of a second rotation operation around a second direction intersecting the first direction. The light scanning unit scans the laser light by the first and second rotation operations. The focus controller is provided between the light source unit and the light scanning unit in an optical path of the laser light to modify a convergence of the laser light. An angle between a plane including the first and second directions, and an image surface is not less than 80 degrees and not more than 100 degrees.
