Micro-lens array substrate and production method therefor, and projection type liquid crystal display unit using those

摘要

In a micro-lens array substrate ( 12 ) that includes first and second micro-lens arrays ( 6, 7 ) respectively having a plurality of lenses, the first micro-lens array ( 6 ) is sandwiched between two inorganic dielectric substrates ( 21, 24 ), and the second micro-lens array ( 7 ) is formed on one of the two inorganic dielectric substrates ( 21, 24 ).
