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 1):
A microlens array diffuser plate comprising a single lens group positioned on a surface of a transparent substrate,\n wherein 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 the following Equation 1 and Equation 2, [ Math . \ue89e 1 ] z = cx 2 1 + 1 - ( 1 + k ) \ue89e c 2 \ue89e x 2 ( Equation \ue89e \ue89e 1 ) - 40 \u2264 k \u2264 - 20 ( Equation \ue89e \ue89e 2 ) where, in the above Equation 1 and Equation 2, z represents a height difference with a reference plane that is a plane which passes through a peak of the single lens in a height direction and is orthogonal to a lens optical axis of the single lens, c represents an inverse of a curvature radius of the single lens, x represents a separation distance from the lens optical axis of the single lens, and k represents a conic coefficient.
