Abstract
A pixel of an organic electroluminescence (EL) display apparatus includes an EL element and an added capacitor connected in parallel with the EL element. The added capacitor provides improved image quality. To further improve image quality, an added resistor may be connected in series with the EL element, and in parallel with the added capacitor. Alternatively, the added resistor may be connected in series with the added capacitor, and in parallel with the EL element. The pixel may be used in both a simple matrix display system or an active matrix display system.
