Abstract
There is disclosed a lightweight and small liquid crystal display which achieves low power consumption and in which the optical anisotropy of the liquid crystal material is compensated for in order to enhance the viewing angle characteristics and the response speed of the liquid crystal material. Display electrodes and a common electrode are formed on one of the substrates. The orientation of the liquid crystal material is of the HAN (hybrid alignment nematic) type. This compensates for the optical anisotropy of the liquid crystal material and improves the response speed.
Claims1
A method of driving a liquid crystal display device,
- said liquid crystal display device comprising:
- a first insulating substrate;
- a second insulating substrate being disposed opposite to the first insulating substrate;
- a first electrode being formed over the first insulating substrate;
- a second electrode being formed over the first insulating substrate;
- a liquid crystal material being interposed between the first and second insulating substrates;
- said method comprising the steps of:
- producing a parallel electric field to the first insulating substrates, said parallel electric field being generated between the first and second electrodes, and
- driving the liquid crystal material by the parallel electric field.
