Abstract
A head mounted display (HMD) apparatus is provided. The HMD apparatus includes a first lens, a second lens, a first micro-display disposed on the first lens, a second micro-display disposed on the second lens, a first light source, a second light source, and an eyeglass frame. A first side of the first micro-display corresponding to a first rubbing alignment processing direction and a first side of the second micro-display corresponding to a second rubbing alignment processing direction are symmetric with respect to a center line of the eyeglass frame between the first lens and the second lens. A first incident light emitted by the first light source is obliquely emitted from the first side of the first micro-display toward the first micro-display and a second incident light emitted by the second light source is obliquely emitted from the first side of the second micro-display toward the second micro-display.
