1. A resin lens plate having oblong shape comprising:
A lenslet forming area at the center of one or both of its surfaces where a matrix of convex lenslets each having a spherical
or aspherical end surface are regularly arranged such that adjacent lenslets are apart from each other by a specified center-to-center
pitch; and
margins around the central lenslet area where no lenslets are formed,
wherein each convex lenslet has a quadrangular or hexagonal contour in a plan view of the plate; and the direction in which
the center-to-center distance between adjacent lenslets takes a maximum value is in parallel with the lengthwise side of the
plate, and
wherein a transparent conductive film is formed on the surface of the plate in such a manner as to allow the potential level
of the transparent conductive film to be adjusted.
