PURPOSE: An image displayer and its structure is provided, which is for projecting real time images to a large scale screen and well maintaining image displaying unit(a liquid crystal type TFT, LCD, etc), film and lens by reducing or blocking heat using vacuum image displayer. CONSTITUTION: Present invention uses the principle that the heat transmission rate is low in the vacuum environment. Within a vacuum image displayer(10), a light goes through a light bulb(60), reflector(70), second vacuum part(20A), lens(80) and first vacuum part(20). The output image from the first vacuum part(20) is projected to an image displaying unit(TFT, LCD)(30), and goes through a film(50), complex lens(80A) and into a screen(100). The image and sound of an image-sound controller(40) are separated, and the image is transmitted to the image displaying unit(30), and the sound goes to an amp(200) and a radio wave transmitter(300).
