PURPOSE: To provide a low electric power consumptive, simple constitutional, large areal, thin type, and lightweight cathode-ray tube by adopting a cold cathode formed by using an electroluminescent element to emit ultraviolet radiation or visible radiation and a photoelectric material having an external photoeffect.
CONSTITUTION: A plurality of first stripe shape electrodes 2 are formed on a glass substrate 1, and a first insulating material layer 3 is formed above it. An emissive material layer 4 is formed on the first insulating material layer 3, and a second insulating material layer 5 is formed on the emissive material layer 4, and a plurality of second stripe shape electrodes 6 are formed lastly in the orthogonal direction to the electrode 2, so that an electroluminescent element can be completed. A network material 7 composed of photoelectric material wires is arranged on the electroluminescent element. An insulating barrier 9 is also formed on the other glass substrate 8, and red phosphor 10, insulating phosphor 11 and blue phosphor 12 are arrayed periodically inside of it, and An Al thin film anode 13 is arranged further on the phosphor.
