Document Type and Number:

WIPO Patent Application WO/2008/010424

Kind Code:

A1

Abstract:

A long or large-area erecting equal-magnification lens array plate little in degradation of the optical performance. A long flat plate lens array plate (10) manufactured by a manufacturing method of this invention is formed by joining together flat plate lens array plates (1) with regularly arranged lens parts in the longitudinal direction. Joint parts (3) are linearly formed at the positions where the lens parts are not included. Consequently, the long erecting equal-magnification lens array plate of any length can be formed.
