Provided is a display apparatus capable of supplying a high voltage to a display device. Pixels have a function for holding first data, and a function for adding second data to the first data to generate third data, and supplying the third data to the display device. Capacitive coupling by capacitors is used for data addition. Elements, including the capacitors, are shared by vertical (direction in which the source line extends) pixel pairs and therefore each capacitor can be provided with the installation area of two pixels and the capacitance value can be increased. Thus, it is possible to efficiently perform data addition by capacitive coupling. |
