Abstract:
An optical device for exit pupil expansion (EPE) for improving a field of view (FOV) and luminance uniformity, and a display apparatus including the same are provided. The optical device includes: an input part into which a virtual image is input; and an EPE part configured to receive the virtual image from the input part, perform one-dimensional (1D) EPE and two-dimensional (2D) EPE to combine the virtual image with an external real image, and output the combined image.
