Abstract

See full text

A display device capable of driving at low power consumption is provided. In a display device (1) for displaying images by supplying voltages on the sub-pixel electrode (Ep) and the common electrode (Ecom), the display device (1) includes a voltage selection circuit (102) for receiving first and second refresh voltages (4V and −5V). The voltage selection circuit (102) supplies the first refresh voltage (5V) on the sub-pixel electrode (Ep) through a first current path (Pa) when the data voltage on the sub-pixel electrode (Ep) is −5V, while the second refresh voltage (−5V) is supplied to the sub-pixel electrode (Ep) through a second path (Pb) when the data voltage on the sub-pixel electrode (Ep) is 5V.
