Abstract
A display apparatus providing a virtual image to user is provided. The display apparatus may include a hologram optical element on a path of light emitted from a display panel. The display panel may emit light having different peak wavelength ranges. The reflection angle or the refraction angle recorded in the hologram optical element is different according to the peak wavelength range. Thus, the display apparatus may provide a plurality of virtual images having different focal lengths to the user without physical movement or mechanical operation of the display panel.
