Abstract
A liquid crystal display device for enlarging and projecting an image displayed on a transmission liquid crystal display panel through a projecting lens onto a screen by radiating a light from a light source to the panel, has a heat pipe inserted into a transparent cooling vessel filled with transparent cooling liquid for externally radiating heat absorbed by the liquid to suppress the temperature rise of the panel due to the light incident to the panel.
