ABSTRACT:
A projection type display apparatus includes a housing having a first side having an air intake opening and a second side having an air exhaust opening, a light source for supplying light, and a light valve device which modulates the light output from the light source. A centrifugal fan is associated with the air intake opening so as to draw air from the air intake opening. A first ventilation path is coupled with the air intake opening so as to lead air flow from the air intake opening toward a lower portion of the light valve, and a second ventilation path is formed from the lower portion of the light valve to an upper portion of the light valve. An exhaust fan is associated with the air exhaust opening so as to draw out air flowing from the second ventilation path through the air exhaust opening.
