Abstract: A cold cathode fluorescent lamp for a backlight of a liquid crystal display device includes a light-transmitting glass tube in which a rare gas and mercury are sealed, and a phosphor film which is formed on an inner peripheral surface of the glass tube. The phosphor film is formed such that a phosphor suspension is formed by mixing phosphors into a suspension produced by strongly stirring a mixed solvent made of butyl acetate and nitrocellulose and by re-stirring the mixture, and the phosphor suspension is applied to the inner peripheral surface of the glass tube by coating.

Abstract: The present invention provides a liquid crystal display device which can enhance the brightness of a backlight of a liquid crystal display panel in such a manner that a luminous flux quantity of a cold cathode fluorescent lamp is increased. It is also an object of the present invention to provide a manufacturing method of such a liquid crystal display device.

Abstract: A reflection film for reflecting electron beams is provided between an inner surface of a face plate and a phosphor layer. The electron beams which pass through a phosphor layer are reflected on the reflection film and are incident on the phosphor layer. Since the electron beams are reflected on the reflection film, the browning of the face plate can be decreased.
