<p>A display device of the present invention is a display device of an active matrix type, and includes a display driver supplied with image data (DR, DG and DB) included in serial data (SI) by serial transmission. The serial data (SI) is provided with a first flag (D1) for specifying a polarity of voltage (Vcom) of a common electrode. The display driver extracts the first flag (D1) from the serial data (SI) in accordance with a timing of a serial clock (SCLK), and performs display in accordance with the image data (DR, DG and DB), while generating the voltage (Vcom) of the common electrode which voltage has the polarity specified by the first flag (D1) extracted. This realizes a display device capable of generating a timing signal for AC common voltage, while having a small circuit.</p> |
