Abstract
A display apparatus includes a display panel configured to output light for displaying a mixed image including a first image and a second image, and a filter device disposed at a light exit side of the display panel and including a first filter lens and a second filter lens, orthographic projections of the first and second filter lenses on a light-emitting surface of the display panel do not overlap, and wavelength ranges of light that the first filter lens allows to transmit do not overlap with wavelength ranges of light that the second filter lens allows to transmit. Wavelength ranges of light for displaying the first image are within the wavelength ranges of the light that the first filter lens allows to transmit, and wavelength ranges of light for displaying the second image are within the wavelength ranges of the light that the second filter lens allows to transmit.
