A display apparatus includes an image forming device configured to provide image light, a polarization controller configured to adjust a polarization state of the image light provided from the image forming device, a processor configured to control the polarization controller, based on image information to be provided to a user, a polarization beam splitter provided in a first optical path where the image light travels, the polarization beam splitter configured to reflect light of a first polarization, and transmit light of a second polarization that is different from the first polarization, and a first curved mirror provided in a second optical path of first image light among the image light reflected from the polarization beam splitter and configured to focus the first image light on a first virtual plane at a first depth position.
