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 (LN11, LN21). Each of the two polarization-dependent lenses (LN11, LN21) may have a focal length that varies based on a polarization state of incident light. The two polarization-dependent lenses (LN11, LN21) may have optically different characteristics with respect to the first and second images (L11, L21). The display apparatus may further include at least one wave plate (WP11, WP21) and/or at least one polarizer (LP11, PT11) provided between the two polarization-dependent lenses (LN11, LN21) or outside thereof.

The present disclosure relates to the field of display technology, and discloses a light-emitting diode display panel and a method of fabricating same. The light-emitting diode display panel comprises a first substrate, a second substrate, a polarizer layer and a »/4 phase retarder film, the polarizer layer and the »/4 phase retarder film being arranged such that incident ambient light passes in turn through the polarizer layer and the »/4 phase retarder film to arrive at the first substrate. The present disclosure effectively prevents the impact of reflection of the ambient light on the displayed image and thus improves the display quality, by arranging both the polarizer layer and the »/4 phase retarder film in the light-emitting diode display panel.
