FLAT PANEL DISPLAY

摘要

A flat panel display is provided to prevent the variation of a current supplied to liquid crystal device or organic electro luminescence device of the flat panel display due to the leakage current and suppress image deterioration. In a flat panel display, a control electrode is electrically connected to the scanning line and a first switching device(S1) is connected between data line(Data(m)) and the first supply voltage line(VDD). A second switching device is electrically connected between the first switching device and the first supply voltage line. A capacitive device(Cst) is connected between The first switching device and second switching device. The driving transistor(MDR) is electrically connected between the second supply voltage line and the first supply voltage line while connecting the control electrode to the second switching device. An organic electro luminescence device(OLED) is electrically connected between the driving transistor and the second supply voltage line.
