A display apparatus has a liquid crystal display having a display panel, a housing, a circulating fan, and an air conditioner. The housing has a sealing part. The sealing part seals around the display panel and accommodates the display panel therein, while making the display screen viewable from outside. The circulating fan circulates air along a circulation path surrounding the display panel wherein the path includes a space between the display screen and the sealing part. The air conditioner collects heat from the air circulating the circulation path and releases the heat to outside of the housing.
