PROBLEM TO BE SOLVED: To prevent an inappropriate output operation of scanning signals even when the same scanning line drive units are used in a mode of driving scanning lines from both ends.SOLUTION: First and second scanning line drive units are arranged on both ends of scanning lines, and each scanning line is driven from both ends. In a state of being connected to first to m-th scanning lines, the first scanning line drive unit outputs scanning signals in a forward direction from a first output terminal to a m-th output terminal. In a state of being connected to the first to m-th scanning lines, the second scanning line drive unit outputs scanning signals in a reverse direction from the m-th output terminal to the first output terminal. Here, the first scanning line drive unit causes the scanning signals from the odd-numbered output terminals to have a first blanking period and the scanning signals from the even-numbered output terminals to have a second blanking period. Further, the second scanning line drive unit causes the scanning signals from the odd-numbered output terminals to have the second blanking period and the scanning signals from the even-numbered output terminals to have the first blanking period. This can prevent different scanning signals from being outputted from both ends. |
