Abstract: A video projector including an light emitting tube which emits light to display an image, a reflector encompassing the light emitting tube and defining a reflection chamber, a cooling fan which generates a cooling airflow for cooling the light emitting tube, and a duct defining a cooling airflow passage, which includes a bent portion, arranged between the cooling fan and the light emitting tube. An airflow redirection member adjusts the direction of the cooling airflow in the cooling airflow passage. The airflow redirection member includes an open portion, which allows passage of the cooling airflow from the duct into the reflection chamber of the reflector, and a closed portion, which forms stagnation of the cooling airflow in the duct.

Abstract: A projection display device includes: a light modulator for modulating light from a light source; a polarizer disposed at a position facing the light modulator; a cooling section for allowing an air to flow in a space between the light modulator and the polarizer; and an air deflector for deflecting the air flowing in the space between the light modulator and the polarizer toward the polarizer.

Abstract: A video projector includes a first discharge port from which a cooling current is sent out of a duct to an optical component. A cooling fan generates the cooling current which flows through the duct. The first discharge port includes first and second wall surfaces opposed to each other in an optical axis direction in which the light is transmitted through the optical component, third and fourth wall surfaces opposed to each other in a lateral direction perpendicular to the optical axis direction, a discharge port inlet into which the cooling current from the cooling fan is drawn, and a discharge port outlet from which the cooling current is sent toward the optical component. A gap between the first and second wall surfaces and a gap between the third and fourth wall surfaces become narrower from the discharge port inlet to the discharge port outlet.

Abstract: A liquid crystal projector device of the present invention includes three image generating units for generating image light of three primary colors. Each image generating unit has a polarizing plate and an optical compensating plate held by a combination frame and placed on a support base. The combination frame includes a polarizing plate frame for holding the polarizing plate, and a compensating plate frame for holding the optical compensating plate. The polarizing plate frame is supported on the support base via a rotation adjustment mechanism for rotating the polarizing plate about the optical axis, while the compensating plate frame is supported on the polarizing plate frame via an inclination adjustment mechanism for inclining the optical compensating plate by rotating the optical compensating plate about two axes perpendicular to the optical axis and perpendicular to each other.
