PROBLEM TO BE SOLVED: To eliminate efficiently oil mist and dust.SOLUTION: A video display device includes a video processing unit, a cooling fan, a filter, and a cooling duct. The video processing unit generates and displays video signals. The cooling fan generates a current of cooling air to cool the video processing unit. The filter is disposed in the intake side of the cooling fan and removes dust. The cooling duct is a ventilation path for the current of cooling air, and a recessed bay-shaped portion is provided at a downstream position thereof by a projection formed at the outlet end of the ventilation path and a ventilation wall. The bay-shaped portion provided on the cooling duct captures oil mist, and dust not fully removed by the filter, which are moved aside to the ventilation wall by the current of cooling air generated by the cooling fan. |
