(57) ABSTRACT

Aspects of the invention are intended to stabilize the initial state of an active matrix so as to reduce unnecessary power consumption and stabilize the operation. The driving device can include a selection device that is coupled to any of a plurality of row direction lines and any of a plurality of column direction lines, and by which a selected state and a non-selected state of the row direction lines or the column direction lines are switched to each other. The driving device can also include a device that switches to the non-selected state that switches the selection device coupled to the row direction lines or the selection device coupled to the column direction lines to a non-selected state. Selection by the selection device can be implemented after the selection device is switched to a non-selected state by the device that switches to the non-selected state.
