Abstract
The present invention provides a liquid crystal display pixel structure and a manufacture method thereof. The liquid crystal display pixel structure comprises: a lower substrate, a passivation layer located on an upper surface of the lower substrate, a pixel electrode located on the passivation layer, an upper substrate, and a common electrode located on a lower surface of the upper substrate; each pixel comprises multi domains; in one pixel, the passivation layer comprises at least two trench structures having different depths, and the pixel electrode uninterruptedly covers on the trench structures, the trench structures having different depths divide the one pixel into different areas to realize that liquid crystals in different areas of the one pixel have different twisted angles under the same driving voltage. The liquid crystal display pixel structure of the present invention is capable of improving the color washout phenomenon under wide view angle, and simplifying the driving control circuit and raising the pixel aperture ratio.
