Abstract
We have developed a new vertical alignment mode that uses a valley or hole as a source of moving liquid crystal when the voltage is applied. As the valley or hole can be made by the same process steps as the TN color filter, this new VA mode can be manufactured by the simplest process steps than any other TFT-LCD modes. We also have found that liquid crystal aligns parallel to the surface of the valley or hole when the voltage is applied. Finally, the electro-optic characteristics of this mode are studied with various parameters such as the birefringence and pitch of liquid crystal.
