  • Patent number: 10114254
    Abstract: The present invention provides a pixel structure and a manufacturing method thereof. The pixel structure according to the present invention is such that two pixel electrodes that are not connected to each other are arranged in a single pixel structure and the two pixel electrodes are respectively connected to two data lines through respective thin-film transistors. In normal displaying, the two data lines are respectively applied with different voltages so that the two pixel electrodes are respectively set at different potentials. The different potentials of the two pixel electrodes cause liquid crystal molecules that are close to different ones of the pixel electrodes to show different polar angles so as to achieve distribution and existence of multiple polar angles in the liquid crystal, reducing the amount of phase difference of liquid crystal in different directions and thus improving the view angle and color shift of a vertical alignment liquid crystal display.
