Title: OPTICAL DEVICE AND DISPLAY APPARATUS
Abstract:
This optical device is provided with: an incidence surface and an emission surface which are opposed to each other; and a plurality of reflection parts which are disposed between the incidence surface and the emission surface and which each reflect, toward the emission surface, light incident on the incidence surface. The plurality of reflection parts each have a first reflection surface and a second reflection surface which are disposed to be orthogonal to each other. The line on which the first reflection surfaces and the second reflection surfaces intersect each other is inclined relative to the normal line of the incidence surface.
