Title:
PHOTOCONDUCTIVE ELEMENT AD DISPLAY USING IT
Document Type and Number:
Japanese Patent JP3395255
Kind Code:
B2
Abstract:
PURPOSE: To provide a thin, sensitive, and compact photoconductive element which is strong against external environment.
CONSTITUTION: A number of electric field release type cathodes with an emitter 4 on a cone are provided on an amorphous silicon substrate 1 using a semiconductor technology and then an anode electrode 6 for taking out emission current which has been changed by applying light to the amorphous silicon substrate 1 is provided opposite to the emitter 4, thus constituting the photoconductive element which is vacuum-sealed in a glass tube.
