Abstract
A driving device drives a liquid crystal display panel in which the number of source lines is by one larger than the number of columns of pixel electrodes and in which the columns of pixel electrodes are arranged between the source lines. The driving device has a configuration in which potential output terminals, in a central region, are not connected to any source line. A voltage follower is connected to an output switching section. Additionally, potential output terminals are connected through switches to input terminals, respectively. The switch connects a first terminal to a second terminal with control signal at a high level and connects the first terminal to a third terminal with at a low level.
