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, 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 at least one planar reflective structure is disposed between the first side surface and the second side surface, and the planar reflective structure is parallel to the first side surface. The planar reflective structure and the light entering surface have a distance therebetween.
