Light projection device and display device

Abstract

The purpose of the present invention is to provide a light projection device that can allow image light to enter an eyeball of a user at a wide viewing angle from a desired direction, regardless of the orientation of the eyeball. The light projection device of the present invention includes: an image light generation system that generates image light; and a projection system that projects the image light generated by the image light generation system onto an optical element worn on or embedded in an eyeball of a user, in which the projection system includes a diaphragm that is disposed on an optical path of the image light from the image light generation system and that is variable in at least a diaphragm position.
