To appropriately cool a specific part which is easily heated in a video display apparatus and to prevent dust entry into the video display apparatus.

A filter 50 for cleaning air is attached to an aperture 41 formed on a rear face of a cabinet and air is taken from outside the cabinet to inside the cabinet through the aperture 41 by an intake air fan 60, and inside of the cabinet is cooled by the taken air. Moreover, when a highly heated section 31 has a high temperature, the highly heated section 31 is securely cooled by extending a duct 70 toward the highly heated section 31 from the intake air fan 60 and by expanding and contracting the duct 70 according to the temperature in the highly heated section 31.
