A display device includes a front substrate having an anode and fluorescent materials on an inner surface, and a back substrate having a plurality of cathode lines and include electron sources, and a plurality of control electrodes allow electrons from the electron sources to emit to the front substrate side, on an inner surface thereof. The back substrate is arranged to face the front substrate in an opposed manner with a given gap therebetween, and an outer frame for holding the given gap is interposed between the front substrate and the back substrate and extends around the display region. An inner frame is arranged outside the display region and inside the outer frame, and a getter is provided between the outer frame and the inner frame.
