    • PURPOSE:To miniaturize the display device and to improve resolution by constituting the display device of a color image display device for one horizontal scanning line provided with three primary colors emitting means arranged in parallel with a horizontal scanning line section and an optical system means for deflecting image light for one scanning line projected from the display device in the vertical direction. CONSTITUTION:The display device is constituted of a cathode ray tube (CRT) 1 provided with three primary colors emitting means 14B, 14R, 14G arranged in parallel with the horizontal scanning line section and three electron gans 4B, 4R, 4G making pairs with the means 14B, 14R, 14G, a horizontally deflecting coil 2, the optical system 16 for deflecting image light for one horizontal scanning line projected from the CRT 1 in the vertical direction synchronously with a vertically synchronizing signal included in an image signal, and a driving device 17 for driving the optical system 16. Cathode rays are projected from the three electron gans 4B, 4R, 4G and deflected in the horizontal direction by the coil selectively emit the corresponding light emitting means 14B, 14R, 14G. In addition, image light raidated from the CRT 1 is deflected in the vertical direction by the optical system 6 to constitue an image. Thus, the display device can be miniaturized and high resolution can be attained.
