Estimating the term…
In a projection image display apparatus, a noise removal filter portion 15 is separated from a power source unit body 14. The separated noise removal filter portion 15 is 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 14, respectively. Specifically, the power source unit body 14 is 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 portion 15 is provided in a position opposed to the power source unit body 14 in 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.
A projection image display apparatus having a noise removal filter portion for removing noise coming via a power source inlet and comprising a power source unit for supplying power to the respective parts including a light source lamp stored in a housing, which modulates light emitted from the light source lamp based on an image signal to project the modulated image light in an expanded manner,
