Abstract: PURPOSE: A polarization compensating panel in a projection system is provided to prevent the efficiency of polarization compensation from being deteriorated due to thermal stress. CONSTITUTION: A projection system includes a polarized beam splitter and an imager for loading an image on lights transmitted from the polarized beam splitter and reflecting the lights. A polarization compensating panel in the projection system is located between the polarized beam splitter and the imager and includes a plastic plate(QWP) and a polarization compensating panel. The plastic plate is made of polymers having birefringence such as poly carbonate and stretches the polymers to arrange molecules in one direction. The polarization compensating panel is composed of a glass plate(101) attached to both sides of the plastic plate using an optical bond(102) having a coefficient of thermal expansion smaller than that of the material of the plastic plate.
