Filed: 1992-02-28
Abstract: PURPOSE:To reduce the number of parts, to simplify construction and to reduce the size of a fan for cooling a panel by sticking a condenser lens to a polarizing plate. CONSTITUTION:The polarizing plate 21A on the front side of a pair of the polarizing plates 21A, 21B disposed before and behind the liquid crystal panel 7 is directly adhered and fixed by a transparent adhesive to the flat surface facing of the condenser lens 32 facing the liquid crystal panel 7.
