Liquid crystal display device

Abstract

A liquid crystal display device including a liquid crystal layer, a common electrode, and an electrode set is provided. The liquid crystal layer is placed between said common electrode and the electrode set, and the electrode set is provided for switching the liquid crystal layer. The electrode set includes a first electrode and a second electrode. The first electrode switches a first area of the liquid crystal layer. The second electrode switches a second area of the liquid crystal layer. Particularly, the second area includes at least a part of the area of the liquid crystal layer that the first area does not include.

Description

technical field [0001] The present invention relates to a liquid crystal display device, in particular to a vertical alignment (Vertical Aligned, VA) liquid crystal display device. Background technique [0002] Liquid crystal display devices are the most common image display devices. Generally speaking, a liquid crystal display device has two glass panels on which a pixel electrode and a common electrode are respectively disposed, and a liquid crystal layer is interposed therebetween. In short, the principle of the liquid crystal display to generate images is to generate an electric field in the liquid crystal layer by providing voltage to the pixel electrodes and the common electrode, and then determine the axis of the liquid crystal molecules to adjust the polarization direction of the incident light. [0003] Among various liquid crystal display devices, when there is no electric field in the vertical alignment liquid crystal display device, the long axis of the liquid c...

However, this conventional practice tends to reduce the aperture ratio of the liquid crystal display, especially because of the shape of certain electrodes, which will cause the liquid crystal in some areas to never switch, thereby reducing the aperture ratio.
