PURPOSE: A projection television is provided to reduce noise generated by a cooling fan by mounting a resonator to ducts and remove other noise generated by any other parts by controlling the number of the resonator. CONSTITUTION: A projection television includes a lamp(111) as a light source, a circuit driving part(112) for supplying power, a cooling fan for cooling the heat generated from the lamp and the circuit driving part, ducts(120) for inducing air introduced by the cooling fan to discharge to the outside, and resonators(137) mounted to the ducts for removing noise generated by the cooling fan.
