Abstract
PURPOSE: To reduce the dark current and to avoid the deterioration of characterisitics, by constituting the terget with the oxide film consisting of at least either one of Zn or Cd and Sn or Ge and of the photoconductive film taking Se as the major elelment.
CONSTITUTION: Internal the face plate 13, the transparent conductive film 18 picking up signal current as the target 14 is coated, and the photoconductive film 19 taking Se as the major element is coated. In this case, the film 18 is constituted with the conductive oxide film consisting of at least either of Zn or Cd, of Sn or Ge. Thus, the dark current is reduced and the deterioration of characteristics can be avoided.
