[0037] Please refer to Figure 5 to Figure 7 The liquid crystal display device provided by the first embodiment of the present invention includes a display panel 50, and the display panel 50 includes an array substrate 20, a color filter substrate 30 disposed opposite to the array substrate 20, and a color filter substrate located between the array substrate 20 and the color filter substrate 30. Liquid crystal layer 40 .

[0038] A plurality of scan lines 21 and a plurality of data lines 22 are disposed on the array substrate 20 . The plurality of scan lines 21 and the plurality of data lines 22 are insulated and intersect to define a plurality of pixel units arranged in an array. Each pixel unit is provided with a pixel electrode 23 and a thin film transistor 26 , and the pixel electrode 23 is connected to the scanning line 21 and the data line 22 adjacent to the thin film transistor 26 through the thin film transistor 26 . Specifically, the thin film transistor 26 includes...

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an array substrate, a liquid crystal display device and a driving method. Background technique [0002] Liquid crystal display (liquid crystal display, LCD) has the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation and relatively low manufacturing cost, and occupies a dominant position in the field of flat panel display. [0003] With the continuous advancement of liquid crystal display technology, the viewing angle of the display has been expanded from about 120° to more than 160°. While enjoying the visual experience brought by the large viewing angle, people also hope to effectively protect commercial secrets and personal privacy. Avoid commercial loss or embarrassment caused by information leakage on the screen. Therefore, in addition to a wide viewing angle, it is also required that the displa...
