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 4):
The diffuser plate according to  claim 1 , wherein\n the curvature radius of the single lens is larger than a maximum value of a pitch between single lenses in the single lens group, and in a case in which a circumscribed circle that circumscribes a single lens is considered, a minimum value of a diameter of the circumscribed circle in the single lens group is larger than the maximum value of the pitch between the single lenses.
