Abstract
In a projection image display apparatus, a noise removal filter portionis separated from a power source unit body. The separated noise removal filter portionis provided in the vicinity of a side wall of a housing on which a power source inlet is provided, and of the power source unit body, respectively. Specifically, the power source unit bodyis provided along a side wall of a front face of the horizontally-long housing of the projection image display apparatus and the noise removal filter portionis provided in a position opposed to the power source unit bodyin a side wall of the back face. As a result, even when a light source lamp has a higher output, the projection image display apparatus can achieve reduced noise by an improved cooling capability and reduced cost enabled by an efficient Electro Magnetic Compatibility (EMC) measure and the like.
