Abstract
An active matrix drive fluorescent display device capable of preventing misluminescence of phosphor layers. A semiconductor chip which includes a plurality of luminous dots arranged in a matrix-like manner and is arranged in an envelope is covered on a cut surface thereof rendered electrically GND with an insulating cover layer. Such construction eliminates a failure in insulation between electrodes arranged on the semiconductor chip, to thereby prevent misluminescence of the luminous dots, leading to an increase in display quality.
