摘要:Aspects of the invention provide a screen or the like that enables a bright,homogeneous projection image to be observed in a wide range across an area whereviewers are present. A screen having a micro-lens array formed of a plurality of micro-lens elements each having a first surface having a curvature and a second surface of an
almost planar shape through which incident light that comes incident on the first surfacecan be transmitted. A micro-lens element can be aligned on a reference plane having aspecific region, and let an almost central position of a region of the second surface be areference central position, and when a plane that comes in contact with the first surfaceand the reference plane are almost parallel to each other, let a position of a contactpoint of the plane that comes in contact with the first surface and the first surface,projected on the reference plane, be an apical curvature position, then the first surfacehas the curvature by which the reference central position and the apical curvatureposition are varied by a predetermined distance in a predetermined direction, accordingto the reference central position of the micro-lens element on the reference plane.
