Patent attributes
A projection type video display capable of reducing components in number, and attempting to improve a cooling efficiency and a silencing of the video display is provided. Three cooling fans are provided on a plate member arranged within a chassis of the video display of a liquid crystal projector. The plate member is arranged in such a manner as to be spaced apart from a bottom plate of a chassis of the video display in order to form a single external-air introducing duct. Double-bottomed structure is formed by the plate member, and the plate member is used as a bottom for arranging components. Each cooling fan sucks external air from the single external-air introducing duct, and blows the external air from a blowing duct to an object to be cooled (a light source, a liquid crystal display, and others).
