Abstract
A display apparatus includes a transparent display device with a first region displaying images, a second region transmitting external light, the first and second regions being adjacent to each other and alternating in a first direction, a first polarizer on an optical path emitted by the transparent display device and configured to linearly polarize the external light, a first retarder between the first polarizer and the transparent display device to delay a phase of the external light, a second polarizer on the transparent display device to linearly polarize the external light, and a pattern retarder between the second polarizer and the transparent display device, the pattern retarder including a second retarder to delay a wavelength of the external light by a first phase and a third retarder to delay the wavelength by a second phase, the second and third retarders being alternately arranged in the first direction.
