Stereo display device

The invention relates to a stereo display device which is matched with a pair of polarized glasses. The stereo display device comprises a first pixel and a second pixel which are adjacent to each other, wherein the first pixel comprises a first light emitting element and a first light polarization element, and the second pixel comprises a second light emitting element and a second light polarization element. When light rays emitted from the first light emitting element and the second light emitting element respectively pass through the first light polarization element and the second light polarization element and then generate different polarization. Therefore, a left eye image and a right eye image are generated by the adjacent pixels, and a user can view a stereo image by wearing the polarized glasses.
