Liquid crystal display device

Abstract

The invention provides a liquid crystal display device. A first electrode and a second electrode are arranged in a pixel area. The second electrode comprises a plurality of first strip-type conductive parts and a second strip-type conductive part. Each of the plurality of first conductive parts has a first terminal and a second terminal which are opposite to each other. The first terminals of the plurality of first conductive parts are connected together through the second conductive part, and the second terminals of the plurality of first conductive parts are disconnected from one another. Openings are reserved in areas between every two adjacent first conductive parts and close to the second terminals in the first electrode, and electrode bumps are formed by the openings. When the liquid crystal display device works, component electric fields in a direction vertical to the first conductive parts are formed between the electrode bumps of the first electrode and the second electrode. Compared with the prior art, the liquid crystal display device has high light transmittance and quick response.

[0005] However, in the existing FFS liquid crystal display device 10, in the region where the two strip-shaped vertical conductive portions 1242 of the common electrode 124 are located, since the two strip-shaped vertical conductive portions 1242 in the common electrode 124 are connected to the The electric field generated between the pixel electrodes 122 is distributed along both sides of the vertical conductive portion 1242, and in the area between the two vertical conductive portions 1242, the plurality of strip-shaped horizontal conductive portions 1240 in the common electrode 124 are connected to the pixel electrode 122 The electric field generated between them is distributed along both sides of the horizontal conductive portion 1240. Therefore, in the liquid crystal layer of the liquid crystal display device 10, in the area corresponding to the two vertical conductive portions 1242 in the common electrode 124, the liquid crystal molecules are respectively subjected to two different directions. Therefore, after the external driving voltage is applied, the liquid crystal molecules in these two regions will be affected by the electric fields in two different directions, so that the phenomenon of disclination (Disclination line) will appear, that is, the liquid crystal molecules in this region will appear. Different deflection directions, or even basically no rotation, cause the area to always appear in a dark state, reducing the actual transmittance of the pixel
