摘要:
A dedicated control signal electrode is provided between pixel electrodes, and a strong electric field is generated between the control signal electrode and the common electrode to quickly and securely make an initial transition from liquid crystal molecules in a splay alignment state to the same in a bend alignment state. In addition, generating a strong electric field between the control signal electrode and the common electrode even during operation for displaying an image makes liquid crystal molecules stably stay in a bend alignment state. In this case the scan signal electrode, the video signal electrode and the common electrode, which are required for displaying an image, are not used to make a transition from liquid crystal molecules in a splay alignment state to the same in a bend alignment state and make the same stay in a bend alignment state.
