Abstract
A display device has a power line providing a retaining circuit with a power voltage, which is also used as a storage capacitance line connected to one of the electrodes of a storage capacitor. The storage capacitance line is disposed parallel to gate signal lines in a pixel element of the device. The power line of two inverter circuits, which form the retaining circuit, extends in the direction perpendicular to the storage capacitance line and is connected to the storage capacitance line. This configuration helps to reduce the overall size of the display device.
