PROBLEM TO BE SOLVED: To provide a display device capable of reducing the running cost for filter exchange, internal cleaning, maintenance, etc., and suppressing a temperature rise by efficiently cooling the interior of the device without requiring specific equipment etc. SOLUTION: A casing 2 having a hermetic structure includes a display device 10. A duct member 3 forming a flow channel 5 being in contact with the inner surface 20a of the casing is disposed along the surface on the internal space side of a casing wall 20 exposed to the ambient air. An air blowing means 4 for forcibly circulating the internal air is provided to the flow channel 5 extending from an introduction port 31 for introducing the interior air to a discharge port 32 for discharging the air into the internal space. The heat of the introduced internal air is dissipated into the ambient air through the casing wall 20 facing the flow channel 5. COPYRIGHT: (C)2005,JPO&NCIPI
