[0042] image 3 It is a schematic plan view of the liquid crystal display device in the first embodiment of the present invention, Figure 4 for image 3 A schematic plan view of the viewing angle control electrode on the first substrate of the liquid crystal display device, Figure 5 for image 3 Schematic diagram of the disassembled structure of the liquid crystal display device in , please refer to Figure 3 to Figure 5 The liquid crystal display device includes a first substrate 21 , a second substrate 22 opposite to the first substrate 21 , and a liquid crystal layer 23 between the first substrate 21 and the second substrate 22 .
[0043] Generally, when the user views the screen of the liquid crystal display device from different viewing angles, the brightness of the image will decrease as the viewing angle increases. In a traditional Twisted Nematic (TN) liquid crystal display device, the common electrode and the pixel electrode are respectively formed on two differ...

[0069] Figure 9 It is a schematic plan view of the liquid crystal display device in the second embodiment of the present invention, Figure 10 for Figure 9 Schematic diagram of the disassembled structure of the liquid crystal display device in Figure 11 for Figure 9 A schematic plan view of the liquid crystal display device in the black state, Figure 12 for Figure 9 A schematic plan view of the liquid crystal display device in the white state, Figures 13a to 13e for Figure 9 Schematic diagram of the arrangement of negative liquid crystal molecules in a medium liquid crystal display device under different voltages. Please refer to Figure 9 to Figure 12 as well as Figures 13a to 13e The main difference between this embodiment and the above-mentioned first embodiment is that the liquid crystal layer 23 in this embodiment uses negative liquid crystal molecules, and the positions corresponding to each first pixel portion SP1 on the first substrate 21 and the secon...

[0080] Figure 14a and Figure 14b It is a schematic plan view of the liquid crystal display device in the third embodiment of the present invention, please refer to Figure 14a , Figure 14b , the liquid crystal display device is provided with a viewing angle switching button 60 for the user to send a viewing angle switching request to the liquid crystal display device. Angle of view switching button 60 can be a physical button (such as Figure 14a shown), it can also be used for software control or application program (APP) to realize the switching function (such as Figure 14b As shown, set the wide and narrow viewing angles by touching the slide bar). The number of viewing angle switching buttons 60 may be two, so as to control the viewing angles in the left and right directions and the up and down directions respectively. When the user needs to switch between a wide viewing angle and a narrow viewing angle, he can send a viewing angle switching request to the liquid ...
