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.
