A first transistor 131 is provided between the first electrode 121 and the driving circuit 115. A second transistor 132 is provided between the second electrode 122 and the driving circuit 115. A third transistor 133 is provided between the third electrode 123 and the driving circuit 115. Each of the gates of the first transistor 131, the second transistor 132, and the third transistor 133 is coupled to the control circuit 114.
A first holding capacitor 141 is provided between a drain, coupled to the first electrode 121 of the first transistor 131, and a wiring line 116 to which a common signal (COM signal) is supplied. A second holding capacitor 142 is provided between a drain, coupled to the second electrode 122 of the second transistor 132, and the wiring line 116. A third holding capacitor 143 is provided between a drain, coupled to the third electrode 123 of the third transistor 133 and the wiring line 116. The first holding capacitor 141, the second holding capacitor 142, and the third holding capacitor 143 may also be referred to simply as three holding capacitors 141, 142, and 143.
The first transistor 131, the second transistor 132, and the third transistor 133 are all constituted by, for example, N-type TFTs. Hereinafter, the first transistor 131, the second transistor 132, and the third transistor 133 may also be referred to collectively as a transistor 130. Alternatively, the first transistor 131, the second transistor 132, and the third transistor 133 may also be referred to as three transistors 131, 132, and 133.
