Abstract:
An image display apparatus includes plural image forming devices and an observation optical system that includes at least a first optical system configured to fold in a first section a luminous flux from a first image forming device by using a plurality of reflective surfaces and to guide the luminous flux from the first image forming device to the exit pupil, and a second optical system configured to fold in a second section a luminous flux from a second image forming device by using a plurality of reflective surfaces and to guide the luminous flux from the second image forming device to the exit pupil, wherein the first section intersects the second section on an axis that directs from one point in the exit pupil to one point in the observation field.
