Abstract
A head-mounted display device including a display and a beam combiner is provided. The display is configured to emit an image bean, and the beam combiner includes a plurality of stacked light-splitting layers. The light-splitting layers include a first light-splitting layer and a second light-splitting layer. The image beam is adapted to enter and exit the beam combiner through the first light-splitting layer. The first light-splitting layer is located between the second light-splitting layer and the display. The beam combiner satisfies 0.7≤R1/(T1×R2×T1)≤1.3. Here, R1 is light reflectivity of the first light-splitting layer, T1 is light transmittance of the first light-splitting layer, and R2 is light reflectivity of the second light-splitting layer. The head-mounted display device provided herein has advantages of usage convenience and compactness.
