Abstract
A display apparatus includes a light source, a display element configured to modulate illumination light from the light source to generate image light, and an optical system including an optical function unit configured to guide the illumination light to the display element and guide the image light to a projection side. In a first direction parallel to an effective modulation area of the display element, a width of the optical function unit is smaller than or equal to a width of the effective modulation area.
