[0030] Please refer to Figure 3 to Figure 6 The liquid crystal display device 50 with switchable viewing angle provided by the first embodiment of the present invention includes an array substrate 20 , a color filter substrate 30 opposite to the array substrate 20 , and a liquid crystal layer 40 located between the array substrate 20 and the color filter substrate 30 .
[0031] A plurality of scan lines 21 and a plurality of data lines 22 are disposed on the array substrate 20 . A plurality of scanning lines 21 and a 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 , a thin film transistor (not shown) and a common electrode 25 , and the pixel electrode 23 is connected to the scan line 21 and the data line 22 adjacent to the thin film transistor through the thin film transistor. Specifically, the thin film transistor includes a gate, a source and a drain, whe...

[0051] Please refer to Figure 7 to Figure 8 The difference between the liquid crystal display device 50 with switchable viewing angle provided by the second embodiment of the present invention and the first embodiment above is that the liquid crystal layer 40 in this embodiment uses negative liquid crystal molecules. With the advancement of technology, the performance of negative liquid crystal has been significantly improved, and its application has become more and more extensive. In this example, if Figure 7 As shown, in the initial state (that is, the situation where no voltage is applied to the liquid crystal display device), the negative liquid crystal molecules in the liquid crystal layer 40 have a relatively large initial pretilt angle (inclination angle range) relative to the array substrate 20 and the color filter substrate 30. 30°≦θ≦90°), that is, the negative liquid crystal molecules are inclined relative to the array substrate 20 and the color filter substrate 3...
