ABSTRACT:
A precharge circuit is provided with an N-channel transistor intended for switching. A reference potential is applied to either one of the source and drain of this N-channel transistor. The other of the source and drain is connected to a node. A precharge signal is applied to the gate of the N-channel transistor. The reference potential is set to a precharge output potential for the case of displaying black on a pixel, i.e., the potential when a minimum current flows through a P-channel transistor connected to the other of the source and drain of the N-channel transistor.
