Abstract
A driving circuit perform first driving in which, in a first write period, a grayscale potential in an odd-numbered row is supplied to the pixels of a first group and, in a second write period, the grayscale potential is supplied to the pixels in an even-numbered row, and can perform second driving in which, in the first write period, the grayscale potential in the even-numbered row is supplied to the pixels of a second group and, in the second write period, the grayscale potential is supplied to the pixels in the odd-numbered row. In a right eye display period, the first driving is performed in a unit period U1 and the second driving is performed in a unit period U2. In a left eye display period, the second driving is performed in the unit period U1 and the first driving is performed in the unit period U2.
