Patent abstract

A display apparatus is provided. The display apparatus is suitable for a user to view through a polarization component having a first transmittance axis. The display apparatus includes a display module, a polarizer and a biaxial half-wave plate. The polarizer has a second transmittance axis such that a light provided from the display module passes through the polarizer and is converted into a polarized light. The biaxial half-wave plate is disposed on the display module and between the polarizer and the polarization component. The biaxial half-wave plate has a slow axis arranged between the first and second transmittance axes. The polarization of the polarized light passing through the biaxial half-wave plate tends toward the first transmittance axis.
