PURPOSE: A cathode ray tube is provided to make a large screen occupy a small space by disposing an electronic reflection plate made of a crystal inside a funnel so that electron beam deflected by a deflection yoke is reflected to illuminate a fluorescent body of a face funnel. CONSTITUTION: In a cathode ray tube, an electronic reflection plate(30) is established in a direction of electron beam of an electron gun(26) to change the path of the electron beam, so that the electron bean can land on a face panel(20).
