Abstract:
A display apparatus includes 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. The light guide system includes a transparent light-incident portion that includes a light-incident surface on which the image light beams are incident and which 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 are curved surfaces, and a transparent light guide portion of which one end side in a first direction is connected to the light-incident portion. In the light guide portion, the image light beams incident from the light-incident portion are reflected between a first surface and a second surface, and are guided to a light-emitting portion.

Claim (Index 3):
The display apparatus according to  claim 2 ,\n wherein the first surface and the second surface are parallel to each other, and wherein, assuming that a light flux diameter of the parallel light flux when viewed from the third direction is D, that a distance between the first surface and the second surface in the second direction is t, and that an incident angle of the parallel light flux with respect to the first surface and the second surface is \u03b8, the light flux diameter D, the distance t, and the incident angle \u03b8 satisfy the following conditional equation.\n D= 2 t \u00d7Sin \u03b8
