Abstract:
There is provided a diffuser plate, a display device, a projection device, and a lighting device that can achieve flat diffusion angle distribution characteristics while reducing a high-order diffraction component, the diffuser plate including: a single lens group positioned on a surface of a transparent substrate, in which curvature radii of respective single lenses composing the single lens group are varied as a whole, and peak positions of the respective single lenses are located irregularly, and a lens surface shape of at least one of the single lenses in the single lens group satisfies Equation 1 and Equation 2.

Claim (Index 5):
The diffuser plate according to  claim 1 , wherein\n the peak positions of the respective single lenses composing the single lens group are located irregularly within a range of a radius \u0394r with respect to positions of peaks of the respective single lenses in a case in which the single lenses are located regularly, and in a case in which a circumscribed circle that circumscribes a single lens is considered, the respective single lenses composing the single lens group satisfy \u0394r/a\u22600, where a represents a diameter of the circumscribed circle in each single lens.
