Abstract: An electronic device includes blowers. Blowers cool liquid crystal panels for light modulation mounted on illumination optical system for outputting light to a projection lens, respectively, and are disposed on the opposite side to the side where the projection lens of three liquid crystal panels is disposed and are arranged side by side along a first direction facing two liquid crystal panels of three liquid crystal panels.

Abstract: Illumination optical system (101) for outputting light to a projection lens, light source unit (102) for outputting light to illumination optical system (101), and dust-proof case (103) houses illumination optical system (101) and can be divided into two housings are provided, and the dust-proof case (103) has second positioning member (105-1), (105-2) provided on the outer surface of dust-proof case (103) and fitted to and first positioning member (104-1), (104-2) provided in light source unit (102), mounting seating surface (106) provided on the outer surface of the dust-proof case (103) for screwing light source unit (102), and pinching portion (107) for sandwiching a final optical member of light source unit (102) sandwiched between two housings.

Abstract: An electronic device includes a first duct for guiding the air blown out from blowers for cooling a liquid crystal panel mounted on an illumination optical system to the liquid crystal panel, a second duct for guiding the air passing through the liquid crystal panel in the opposite direction of the air blown out from the blowers, a heat sink for removing heat from the air passing through the second duct and a blower holding unit for holding the blowers are provided in a dust-proof case, and the top surface of the blower holding unit, the blower holding unit forms a third duct for guiding the air from which heat has been removed by the heat sink to the air inlet of the blowers that is a space formed along the top surface of the dust-proof case.

Abstract: A electronic device includes blowers. Blowers cool liquid crystal panels for light modulation mounted on an illumination optical system for outputting light to a projection lens, respectively, and are disposed so that the rotation axes of motors of blowers are arranged along a first direction in which two liquid crystal panels face each other on the opposite side of liquid crystal panels from the projection lens.
