Abstract: A driving method for driving an LCD panel having a counter electrode and a source line. In a first period, the counter electrode is driven to a potential VCOMH. In a second period, the counter electrode and the source line are short-circuited to a power supply interconnection having a power supply potential VCI. In a third period, the counter electrode is connected to a ground interconnection while the source line is kept to be short-circuited to the power supply interconnection. In a fourth period, the counter electrode is pulled down to a potential VCOML lower than a ground potential In a fifth period, the source line is driven to a potential corresponding to an image data while the counter electrode is kept to the potential VCOML. The electric power consumed in pulling down the counter electrode from a positive potential to a negative potential can be effectively reduced.
