Abstract: A source-drain voltage of one of two transistors connected in series becomes quite small in a set operation (write signal), thus the set operation is performed to the other transistor. In an output operation, two transistors operate as a multi-gate transistor, therefore, a current value can be small in the output operation. In other words, a current can be large in the set operation. Therefore, the set operation can be performed rapidly without being easily influenced by an intersection capacitance and a wiring resistance which are parasitic on a wiring and the like. Further, an influence of variations between adjacent ones can be small as one same transistor is used in the set operation and the output operation.

The control voltage generator generates a discharge control voltage to be applied to a discharge control line at a slight-on level, which is higher than a gate low voltage and is lower than a gate high voltage, and periodically reduces the discharge control voltage to a level of the gate low voltage in the 3D mode. The control voltage compensator receives the discharge control voltage from the control voltage generator, amplifies a feedback discharge control voltage supplied from a first part of a display panel based on the received discharge control voltage, and applies the amplified feedback discharge control voltage, as a compensated discharge control voltage, to a second part opposite the first part of the display panel.

The first velocity is lower than the second velocity.
