A large scale display device such as a stadium or advertising display in which a plurality of light emitting elements constituted by cathode-ray tubes are arranged in a plane to display color images and characters. Specifically, light emitting elements are constituted by cathode-ray tubes having three primary color light emitting elements. A drive circuit is provided for each color of each of the light emitting element to selectively turn on and off the light emitting element. The drive circuit has brightness adjusting means for adjusting the intensity of light emitted by each light emitting element. A memory circuit is connected to each drive circuit for supplying a binary control signal to the drive circuit to selectively turn on and off the corresponding light emitting element.
