1. A liquid crystal panel, comprising:
- a first transparent substrate having a first principal surface and a second principal surface opposite to said first principal surface;
a second transparent substrate having a third principal surface and a fourth principal surface opposite to said third principal surface, said second transparent substrate being disposed such that said third principal surface faces said second principal surface of said first transparent substrate, with a gap formed therebetween;
a liquid crystal layer interposed between said second principal surface and said third principal surface so as to fill said gap;
at least one transparent film provided on at least one of said first and fourth principal surfaces;
an adhesive layer interposed between said transparent film and at least one of said first and fourth principal surfaces on which said transparent film is provided, wherein said adhesive layer substantially smooths out minor defects on said principal surface associated therewith; and
a dielectric multilayer film provided on said transparent film.

Abstract
A liquid crystal panel includes a liquid crystal layer sandwiched by first and second substrates, wherein a transparent film is adhered on at least one of the first and second substrates by an intervening adhesive layer, such that the adhesive layer fills defects formed on a surface of the substrate with a material having a refractive index close to the refractive index of the substrate. Further, a liquid crystal projector having an improved cooling efficiency is disclosed.
