Display apparatus

A display apparatus comprising:

• an image generation system that emits image light beams as non-parallel light beams;
• and
• a light guide system on which the image light beams emitted from the image generation system are incident without passing through a projection lens system,
• wherein the light guide system including:
• a transparent light-incident portion that includes a light-incident surface on which the image light beams are incident and the light-incident surface is a curved surface, and a plurality of reflection surfaces which convert the image light beams incident from the light-incident surface into parallel light beams and each of the plurality of reflection surfaces is curved surface;
• and
• a transparent light guide portion of which one end side in a first direction is connected to the light-incident portion,
• wherein the light guide portion including:
• a first surface that extends from the one end side toward another end side in the first direction;
• and
• a second surface that faces the first surface on one side of a second direction intersecting with the first direction,
• the light guide portion has a light-emitting portion that is provided at a portion of the second surface away from the light-incident portion, and
• wherein the parallel light beams emitted from the light-incident portion to the light guide portion are reflected between the first surface and the second surface, and are guided to the light-emitting portion.
