Optical waveguide device and head-mounted display apparatus using the same

Abstract

An optical waveguide device and a head-mounted display apparatus using the same are provided. The optical waveguide device used for transmitting an image light includes a light entering surface, a first side surface, a second side surface, a plurality of beam splitters and at least one planar reflective structure. The image light enters the optical waveguide device through the light entering surface. The first side surface is parallel to the second side surface. The beam splitters are disposed between the first side surface and the second side surface. The beam splitters are parallel to each other and are arranged in intervals. The at least one planar reflective structure is disposed between the beam splitters and the light entering surface, and the planar reflective structure is parallel to the first side surface. The planar reflective structure and the light entering surface have a gap therebetween.
