PROBLEM TO BE SOLVED: To change the luminance in an entire image without adversely affecting color tone, contrast or the like. SOLUTION: The image display device includes an emitter 16 connected to each cathode electrode 15, a gate electrode 13, an anode electrode 3, a transistor Tr1, a transistor Tr2 and a capacitor 12. The device displays an image by changing a voltage of each capacitor 12 and can control the luminance of the entire screen by applying a predetermined voltage to the gate electrode 13 and changing the duty ratio Du of the applied voltage.
