Abstract: An augmented reality (AR) display apparatus includes an outputter that outputs first radiation including visual information in a predetermined spectrum, a polarizing plate that absorbs a first s-polarized radiation from the first radiation and transmits a first p-polarized radiation and an optical layer that reflects at least a portion of the first p-polarized radiation incident on a first side of the optical layer with a wavelength corresponding to the predetermined spectrum.

Abstract: A light guide plate and a backlighting device including the light guide plate are disclosed. The light guide plate may include a substrate configured to propagate a first light beam or a second light beam inside the substrate based on an effect of total internal reflection, a prismatic pattern configured to couple the first light beam out of the substrate in a three-dimensional (3D) display mode, and a linear pattern configured to couple the second light beam out of the substrate in a two-dimensional (2D) display mode.
