摘要： On manufacturing a low voltage electron beam excitation phosphor display apparatus (10) which includes an anode (6) having a principal surface and enclosed in a vacuum chamber (1, 2, and 3), a phosphor film (7) formed on the principal surface, and a cathode (9) enclosed in the vacuum chamber opposite to the phosphor film, a phosphor is prepared which consists essentially of an oxisulfide and an oxide which is inevitably formed on a surface of the oxisulfide on preparing the phosphor. The oxisulfide is represented by Ln.sub.2 O.sub.2 S:R, where Ln is at least one selected from a group consisting of Gd, La, Y, and Lu and where R is a rare-earth element. The oxide is removed from the phosphor to produce an oxide-removed phosphor. A pasts comprising a mixture of the oxide-removed phosphor, a conductive material, and an autolytic type binder is coated on the principal surface of the anode which is formed on an insulating substrate (1) constituting the vacuum chamber. The binder of the paste is heated in a nonoxidizing atmosphere to form, on the principal surface of the anode, the phosphor film which has the oxide-removed phosphor and the conductive material. The anode and the cathode are enclosed in the vacuum chamber to obtain a manufactured low voltage electron beam excitation phosphor display apparatus. The oxide may be Ln.sub.2 O.sub.3 into which a component Ln.sub.2 O.sub.2 S of the oxisulfide is changed.
