Method for manufacturing microlens substrate, microlens substrate, opposing substrate for liquid crystal panel, liquid crystal panel, and projection display apparatus
A microlens substrate 1 includes a glass substrate 2 provided with a number of concavities 3 for microlenses, and a glass layer 8 bonded via a resin layer 9 to the glass substrate 2 at a surface thereof provided with the concavities 3. In the resin layer 9, microlenses 4 are formed with a resin filling the concavities 3. The resin layer 9 is formed by curing a resin having a viscosity before curing of not higher than 500 cP at 25&deg; C., particularly an ultraviolet curable resin. An index of refraction n of the resin layer 9 is preferably not lower than 1.35.
