ABSTRACT OF THE DISCLOSURE A cathode ray tube which comprises: an evacuated envelope having at least one transparent flat portion, a fluorescent target arranged on the inner surface of the flat portion, an electron gun within the envelope in laterally spaced relation to the target for emitting an electron beam along a path parallel with the surface of the flat portion, a first deflecting device comprising the target, and an opposite electrode in the envelope for impinging the electron beam upon the target, a second deflecting device comprising a pair of plates to control the electron beam passing therebetween and arranged in the envelope for deflecting the electron beam perpendicularly to the surface of the flat portion, the pair of plates being connected with the opposite electrode and the anode electrode of the electron gun, respectively, and a vertical deflection signal being applied to the anode electrode, and a third deflecting device arranged adjacent to the envelope in cooperation with the pair of plates for concentrating deflecting flux generated by means of the third device on the electron beam between the pair of plates for deflecting the electron beam in parallel with the surface of the flat portion and generally transverse to the direction of the electron beam, thereby to produce an image on the target.
