Abstract
A magnetic display panel includes strips of first electrodes arranged in a first direction on an inner surface of a rear plate. Strips of second electrodes are arranged in a second direction, perpendicular to the first electrodes, and insulated from the first electrodes. Pixel electrodes are installed on each of the intersections of the first and second electrodes, and each has a spiral magnetic field producing unit electrically connected to the first and second electrodes. A magnetic film on the pixel electrodes has a magnetic gap through which a magnetic field produced by the pixel electrodes leaks. A magnetic fluid has a predetermined thickness on the inner surface of the rear plate. Such a display panel can provide moving pictures because of its improved responsivity, and, particularly, is easily fabricated at a low cost in large quantities because of its simple structure. Furthermore, the display panel is advantageous in building super-large display devices based on multiple integration.
