摘要
The invention seeks to reduce inconsistencies in an image to be displayed in a projector. At least one of polarizers 302Bo on the side of a light incident surface and on the side of a light emergent surface is bonded on a sapphire glass plate 308. The sapphire glass plate 308 may preferably be formed of single-crystal sapphire. In addition, the sapphire glass plate 308 may preferably be held by a holding frame 310 made of metal. The sapphire glass plate 308 and the holding frame 310 made of metal may preferably be bonded by an adhesive agent having superior heat conductivity.
