Abstract: A vertical alignment liquid crystal display includes two sub-pixels each with a variable capacitor. A pixel is bisected into a high gray sub-pixel and a low gray sub-pixel through forming a variable capacitor at each sub-pixel. With this structure, the sub-pixels express different grays so that lateral visibility is enhanced. It is not required in bisecting a pixel into two sub-pixels to form separate wires for applying different signals thereto, and the amount of data to be processed at the driver for driving the display device is reduced. Furthermore, a pixel is bisected into two sub-pixels with variable capacitors in a simplified manner, and it is not required to form additional wires and elements, so the aperture ratio is enhanced.

Abstract translation: 垂直取向液晶显示器包括两个分别具有可变电容器的子像素。 通过在每个子像素处形成可变电容器，将像素平分成高灰度子像素和低灰度子像素。 利用这种结构，子像素表示不同的灰度，从而增强了横向可视性。 不需要将像素平分成两个子像素以形成用于向其施加不同信号的单独的线，并且减少用于驱动显示装置的驱动器处理的数据量。 此外，以简化的方式将像素分成具有可变电容器的两个子像素，并且不需要形成附加的线和元件，因此增加了开口率。
