Abstract
A circuit panel includes an array substrate in which a scanning line is formed as a capacitive load and first and second scanning line drivers connected to the scanning line in order to commonly drive the scanning line. Each of the first and second scanning line drivers includes first and second switching circuits connected in series between first and second power terminals to selectively output one of the potentials of the first and second power source terminals as a control signal, and an output buffer for setting the potential of the scanning line in accordance with the control signal. The driving abilities of the first and second switching circuits are uneven.
