A simple cooling construction capable of achieving two functions at a time is to be provided, one function being cooling a lamp as a lighting means and the other function being preventing the scatter of broken pieces of the lamp upon burst of the lamp. An image display device such as an LCD projector has been configured such that cooling air is introduced into the interior of a reflector to cool an lamp means. In this connection, the present invention adopts a net of an expanded metal structure which serves as both means for preventing the scatter of broken pieces of a lamp upon burst of the lamp and an air deflecting plate facing a portion to be cooled. The above two functions can be attained simultaneously by such a simple construction.
