Abstract
PURPOSE: To coat forming a phosphor layer with a closeness further with a uniform thickness, by such means that, a conductive film, made forming in the inner face plate, be made one side electrode, with an electrodeposition processed in the electrolyte having contents of resist and phosphor.
CONSTITUTION: To inner surfaces of a face plate 1, is applied an inorganic transparent conductor film 2, for instance, negative film of indium oxide, tin oxide, etc. or organic conductive film, and used as one electrode with a metal, correspondingly installed to this film, used as another electrode 3, 3, and an immersion is processed in an electrolyte 4, with a required phosphor and negative resist simultaneously comprised, and the phosphor and negative resist are coated simultaneously on the conductive film by applying DC voltage to between corresponding electrodes. In such way, only a processing of immersion in the electrodeposition liquid is required, with no necessity of high speed rotation, capable of constructing a phosphor layer elaborate and uniformly thick.
