Abstract
An electro-luminescence display that is capable of widening an effective display area of a pixel. In the electro-luminescence display, a data line is formed in a direction crossing a gate line. A power supply line is formed in a manner such that it is insulated from the gate line and the data line. A first switching device has a gate connected to the gate line and a source connected to the data line. A second switching device has a gate connected to a drain of the first switching device and a source connected to the power supply line. An electro-luminescence emitting part is connected to the drain of the second switching device. A storage capacitor is formed in a lengthwise direction of the power supply to charge a voltage applied to the gate of the second switching device.
