Liquid crystal display device with multidomain vertical orientation mode

Abstract

The invention discloses a liquid crystal display device with a multidomain vertical orientation mode. The liquid crystal display device comprises a color film substrate, an array substrate, and a liquid crystal layer, wherein the surface of the color film substrate is provided with common collectors; the array substrate comprises a plurality of sub pixel areas, and pixel electrodes are arranged in each sub pixel; the liquid crystal layer is filled between the color film substrate and the array substrate; and the common collectors or the pixel electrodes are provided with domain modulation devices, liquid crystal in each sub pixel is divided into a plurality of domain groups by the domain modulation devices, at least one of the pixel electrodes corresponding to the plurality of domain groups is partially etched, and the plurality of domain groups have basically same areas after the partial etching of the pixel electrodes. By partially etching the pixel electrodes, the liquid crystal display device makes the plurality of domain groups have basically same areas so as to provide the even vertical and horizontal visibility and have no influence on the luminance difference and yield of manufactured products.

Description

[0001] This application is a divisional application of: [0002] Invention name: Liquid crystal display device with multi-domain vertical alignment mode [0003] Application date: August 11, 2008 [0004] Application number: 200810041541.3 technical field [0005] The invention relates to a liquid crystal display device, in particular to a multi-domain vertical alignment mode (Multi-domain Vertical Alignment, MVA / PVA) liquid crystal display device. Background technique [0006] Liquid crystal displays are widely used flat panel displays. The liquid crystal display includes two glass substrates and a liquid crystal layer, wherein the two substrates are provided with electrodes (a pixel electrode and a common electrode), and the liquid crystal layer is between the two substrates. The liquid crystal display generates an electric field in the liquid crystal layer by applying a voltage to the electrodes, and the liquid crystal molecules in the liquid crystal layer are aligned ...

AI Technical Summary

Problems solved by technology

Figure 2A The scheme changes the width between domains, which will cause inconsistencies in the tilt angle and response speed of liquid crystal molecules in domains of different widths, resulting in brightness differences

Figure 2B Although there is no such problem, the overlapping area between the storage line and the pixel electrode and the data line is increased, thus increasing the possibility of short circuit
