Abstract

PURPOSE:To cause an electron beam to necessarily beat a specified fluorescent material and to execute a true color reproduction by arranging one part of a linear cathode or a heating element to generate the electron beam in the periphery of the screen of an picture display device or on the screen. CONSTITUTION:A heater 22 is an example in which one part of a linear cathode 2d is arranged around the periphery of a screen 9. Consequently, when the power source of the picture display device is turned on, beam deflection control electrodes 3-7 are heated by the linear cathode 2, and simultaneously, the screen 9 can be heated by 22 which is one part of the linear cathode 2. As a result, the beam deflection control electrodes 3-7 and the screen 9 can be stretched and contracted at the same coefficient of expansion as a time passes. Thus, the electron beam can beat the specified fluorescent material regardless of a heat, and the true color reproduction can be executed.
