Projector having light source including laser diodes

A projector comprising:

• a light source device consisting of a plurality of laser diodes,
• wherein each of pencils of light emitted by the light source device has a radiation angle differing along a major axis and a minor axis orthogonal to the major axis to define an elliptic section of the each of the pencils of light, and
• wherein the major axis of the elliptic section of the each of the pencils of light is substantially parallel to one another;
• a light guide configured to guide the pencils of light emitted by the light source device, wherein the light guide comprises:
• a rectangular incident port on which the pencils of light emitted by the light source device are incident,
• wherein the rectangular incident port is disposed so that the major axis of the elliptic section of the each of the pencils of light is substantially parallel to the longer sides of the rectangular incident port;
• and
• a rectangular emerging port from which the pencils of light that enters from the rectangular incident port are caused to be emitted;
• and
• a display device comprising a rectangular image forming surface on to which the pencils of light emitted from the rectangular emerging port of the light guide are incident,
• wherein the rectangular image forming surface of the display device is disposed so that the major axis of the elliptic section of the each of the pencils of light emitted from the rectangular emerging port of the light guide is substantially parallel to the longer sides of the rectangular image forming surface of the display device.
