<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing an optical sheet higher in a light directivity and large in the latitude of design, and to provide the optical sheet. <P>SOLUTION: The method of manufacturing the optical sheet 10, which has condensing elements 111 provided on the surface of a substrate 11 having a light transmissive property, and reflection films 14 and aperture portions 15 provided on the rear surface thereof, comprises steps: to form a photosensitive adhesive film 12 with a light transmissive property on the rear face of the substrate 11; to irradiate the substrate from the front face side thereof with parallel light and condense it with the condensing elements 111; to selectively expose the photosensitive resin film 12 with the condensed light; to form the opening portions 15 on exposed light condensing regions 121; to press reflective fine particles to the photosensitive adhesive film 12 on non-condensing regions 122; and to form a reflection film 14 by sticking the pressed reflective fine particles to the non-condensing regions 122. <P>COPYRIGHT: (C)2007,JPO&INPIT |
