Liquid crystal display device with transverse electric field mode

Abstract

The invention relates to a liquid crystal display device with a transverse electric field mode, comprising a color film substrate and an array substrate which are assembled together to fill a liquid crystal therebetween, alignment films with alignment angles of 0 degree are arranged on the color film substrate and the array substrate, an alignment electrode which leads the liquid crystal to have an initial alignment angle of 2 degrees-4 degrees is arranged on the color film substrate, and the alignment electrode is of strip-shaped bodies which are arranged at intervals. The liquid crystal display device adopts the alignment films with the alignment angles of 0 degree and imposes voltage on the alignment electrode arranged on the color film substrate to generate an even alignment state of the liquid crystal with the initial alignment angle of 2 degrees-4 degrees, thereby improving the uniformity of the initial alignment state of the liquid crystal, not causing the differences in phase delay of transmitted light of all the regions in the transverse electric field mode, thus reducing the light leakage defect and improving the contrast.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a transverse electric field mode liquid crystal display device. Background technique [0002] In recent years, liquid crystal display (Liquid Crystal Display, LCD for short) products have been applied to various fields. The main structure of the liquid crystal display device includes a color filter substrate and an array substrate that are boxed together and filled with liquid crystal substances. The liquid crystal molecules are controlled by an electric field, and the transmittance is changed through the anisotropy of the liquid crystal refractive index to display. Fringe Field Switching (FFS for short) generates a transverse electric field between the pixel electrodes in the same plane, so that the liquid crystal molecules between the pixel electrodes and above the pixel electrodes can be rotated in the plane direction, and the viewing angle is increased while improving the li...
