ABSTRACT:
A thin film EL display device wherein an EL layer is interposed between scanning side electrodes and data side electrodes which are arranged to cross one another. A data side driver IC, including switching elements for charging and discharging, is connected to the data side electrodes, and switching circuits for applying modulation voltage are connected to a pull-up common line of the data side driver IC. The switching circuits are provided with switches for removing the charge stored in the thin film EL device after the thin film EL device has emitted light and a capacitor for storing the removed charge, whereby the charge stored in the capacitor can be reused in the next light emission for the purpose of reducing power consumption.
