Abstract:
A display apparatus capable of supplying a high voltage to a display device is provided. A pixel has a function of retaining first data, a function of adding second data to the first data to generate third data, and a function of supplying the third data to the display device. Capacitive coupling by a capacitor is used for data addition. Two pixels provided in the vertical direction (the direction in which a source line extends) share components including the capacitor; thus, the area where the two pixels are provided can be assigned to the capacitor, which can increase the capacitance value. Thus, the data addition by the capacitive coupling can be efficiently performed.
