Abstract
Provided are display apparatuses and electronic apparatuses that include the display apparatuses. The display apparatus may include an optical system that transfers a first image and a second image to an ocular organ of a user. The optical system may include at least two polarization-dependent lenses. Each of the two polarization-dependent lenses may have a focal length that varies based on a polarization state of incident light. The two polarization-dependent lenses may have optically different characteristics with respect to the first and second images. The display apparatus may further include at least one wave plate and/or at least one polarizer provided between the two polarization-dependent lenses or outside thereof.
