Abstract:
A display device comprised by being provided with: an image source for emitting image light; a lens for enlarging the image light and emitting the image light to the viewer side; and an optical sheet disposed between the image source and the lens or on the viewer side of the lens, wherein the optical sheet comprises at least two or more layers, a plurality of convex shapes are formed at interfaces between the layers, a difference Δn in refractive index between the layers adjacent to each other satisfies 0.005≤Δn≤0.1, a half-value angle α of the optical sheet satisfies 0.05°≤α≤0.2°, and a diffusion angle β of the optical sheet at which a maximum brightness becomes 1/20 satisfies β≤5×α.

Claim (Index 1):
A display device comprising:\n an image source that emits image light from a plurality of arranged pixel regions; a lens that enlarges and emits the image light to a viewer side; and an optical sheet that is disposed between the image source and the lens or at the viewer side of the lens, wherein the optical sheet has at least two or more optical layers, and a plurality of unit shapes are formed at each interface between the optical layers.
