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 10):
The display device according to  claim 1 ,\n wherein an amount of transmitted light at a diffusion angle of the optical sheet which is \u22120.1\u00b0 or more and 0.1\u00b0 or less is 30% or more of a total amount of transmitted light passing through the optical sheet, and wherein an amount of transmitted light at a diffusion angle of the optical sheet which is \u22120.3\u00b0 or more and 0.3\u00b0 or less is 95% or more of the total amount of transmitted light passing through the optical sheet.
