<P>PROBLEM TO BE SOLVED: To manufacture thin microlenses having a large radius of curvature. <P>SOLUTION: The manufacturing method includes a process in which a plurality of recessed parts having lens curved surfaces of respective microlenses is formed in lens forming regions of a transparent substrate, a process in which protective material is filled into the plurality of respective recessed parts to form protective films, a process in which a grinding process is conducted to the transparent substrate so that non-lens forming regions surrounding the lens forming regions are retreated with the protective film, a process in which the protective films being retreated by the grinding process are eliminated and microlenses are formed by filling transparent adhesive having a larger refractive index than that of the transparent substrate and a process in which a cover substrate that is made of a transparent plate shaped member is made to adhere to the transparent substrate through the adhesive. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
