Abstract
PURPOSE:To reduce the requirements of dielectric strength for element components, by forming the circuit feeding the scanning voltage to the scanning electrode other than the electrode from the circuit feeding the modulation voltage via the switching circuit at data side connected to the data electrode selected including selected video element and the scanning electrode selected including the selected video element. CONSTITUTION:The dielectric layer is placed at the both sides of EL layer, and matrix electrodes are formed on the both surfaces of the both dielectric layers orthogonally each other. One of the electrodes is taken as the scanning electrodes Y1 to Yn, another is taken as the data electrodes X1 to Xm, and VIa the data side switching circuit 20 connected to the data electrode selected including the selected video elements, the driver is formed with the power supply circuit 40 applying the modulation voltage Vp and the scanning power supply circuit 60 feeding the scanning voltage Vs to the scanning electrode other than the electrode from the scanning electrode selected including the selected video element, and the requirements of dielectric strength for element and components can be reduced.
