Lens holding jig and method for manufacturing lens substrate using the same

摘要

The lens holding jig (3) includes a lower holding portion (15) that holds the lower surface of the lens base (1). The upper surface of the lower holding portion (15) forms a support surface (16) that supports the lower edge (S1, S2) of the edge surface (1a) of the lens substrate (1) at two points. In the center of the support surface (16), a coating liquid escape portion (17) extending downward is provided. The coating liquid escape portion (17) is formed of a long hole, a long groove, or a protrusion.
