A high-intensity, uniformed luminescence, high-density active matrix fluorescent display tube having plural pixels, plural scanning lines and plural signal lines is disclosed. The display element includes a logic circuit, a holding unit, an AND circuit, a pre-driver circuit, and a pixel driver. The logic circuit is composed of a row address selection circuit for each pixel, input data and a logic control circuit. The holding unit drives an anode electrode disposed for each pixel. The AND circuit performs logical product on a signal held in the holding unit and a blanking reverse signal from an input data signal line. The pre-driver circuit drives the output transistor in the previous stage. The pixel driver is conformed of the driver output circuit connected to the pre-driver circuit. The pre-driver circuit is formed of an enhancement-mode P-channel field-effect transistor and a depletion-mode P-channel field-effect transistor.
