Abstract
An image display device has a light source; a power supply section that supplies power to a light source; a cooling fan that cools the light source; a input section; and a control section that controls the cooling fan and the power supply section. If a first lighting mode in which a power value supplied to the light source is a first setting value is designated through the input section, the control section causes the power supply section to supply power that corresponds to the first setting value to the light source and causes the cooling fan to operate.
