Abstract
A display apparatus includes an optical see-through display apparatus, and includes a light source that emits lights a combiner including a diffraction member that diffracts light incident from the light source and outputs the light, and a controller that controls light emission of the light source. The controller controls a light output of the light source on the basis of a wavelength of light outputted from the light source and diffraction efficiency of the combiner that is changed resulting from change in a wavelength of incident light.
