Abstract

The invention discloses an edge electric filed switching type liquid crystal display device which comprises a first substrate and a second substrate, wherein gate lines and data lines which are mutually crossed are arranged on the first substrate to form a pixel region; a thin film transistor is arranged on the first substrate and connected with the gate lines and the data lines; a common electrode is arranged on the first substrate and positioned in the pixel region; a pixel electrode has an annular structure which is arranged on the common electrode and partially overlapped with the common electrode; the pixel electrode is connected with the thin film transistor; the compensating structure of the pixel electrode is arranged in the non-overlapping region of the pixel electrode and the common electrode; the compensating structure of the pixel electrode is connected with the pixel electrode; the second substrate is arranged corresponding to the first substrate; and a liquid crystal layer is arranged between the first substrate and the second substrate.

Description

【Technical field】 [0001] The present invention relates to a liquid crystal display device, in particular to a fringe field switching type liquid crystal display device (fringe field switching type LCD, FFS-LCD for short) with high transmittance. 【Background technique】 [0002] At present, the use of liquid crystal displays (LCDs) has become a trend. LCDs have superior characteristics such as high image quality, better space utilization, low power consumption, and no radiation. With the increasingly mature technology of LCDs, LCDs Widely used in various fields. In the traditional twisted nematic liquid crystal display (TN-LCD), the pixel electrodes are arranged on the first substrate, and the common electrodes are arranged on the second substrate, and the liquid crystal layer is arranged between the first substrate and the second substrate, and through the The pixel electrode and the common electrode apply voltage to control the rotation of the liquid crystal molecules in th...
