Projection television receiver

Abstract

Leak of refrigerant leak is prevented. Further, invasion of impurities into refrigerant liquid is prevented, and a stable projection image is obtained. The assembling steps are curtailed, and the projection television receiver is manufactured by a smaller number of assembling steps, and the cost is reduced. Moreover, a stable quality is maintained for a long period, and a high reliability is obtained. It includes a cathode-ray tube having a face surface, a projection lens disposed ahead of the face surface, a container disposed between the face surface and projection lens, a first sealing member disposed between the container and face surface, a second sealing member disposed between the container and projection lens, and liquid filling up the region enclosed by the container, face surface and projection lens. The container has a fluoride resin film disposed at least inside of the container, and the fluoride resin film contacts with the liquid.
