Abstract
In an active matrix system, a pixel of a display apparatus includes an electroluminescence (EL) element, a diode type driving element connected in series to the EL element for driving the EL element, an added capacitor and an added resistor. The added resistor is connected in series with the added capacitor, and the added resistor and the added capacitor are connected in parallel to the EL element. The added capacitor improves a writing characteristic and a holding characteristic of the pixel, such that a high quality image can be displayed.
