LIQUID CRYSTAL DISPLAY, METHOD OF MANUFACTURING THE SAME, METHOD OF DRIVING LIQUID CRYSTAL DISPLAY |
摘要 |
Before starting a normal display operation of a liquid crystal display of bend alignment type, it is necessary to align the liquid crystal over the display part including all the pixels from the spray-aligned state to the bend-aligned state uniformly. However, conventionally, even when a simple AC voltage is applied, transition sometimes does not occur, or it takes a long time to cause transition to occur and consequently defective displaying due to defective alignment is liable to occur. A method of driving a liquid crystal display including an OBC cell, according to the invention, comprises applying an AC voltage on which a bias voltage is superposed between an electrode (22) and a pixel electrode (23) on substrates before starting a normal display operation and applying a zero or low voltage between the substrates. The two voltage applications are repeated alternately to cause bend alignment transition of all the pixels. After that, the operation is changed to a normal display operation.
