Abstract
The present application provides a pixel structure and a display panel. Each of a plurality of sub-pixel units includes a main sub-pixel, at least one secondary sub-pixel, and a thin film transistor electrically connecting the main sub-pixel and the at least one secondary sub-pixel, wherein by controlling a pretilt angle of a first branch electrode of the main sub-pixel to be different from a pretilt angle of a second branch electrode of the secondary sub-pixel, a driving voltage of the main sub-pixel and a driving voltage of the secondary sub-pixel are different, so that color shift can be effectively alleviated and wider viewing angles can be obtained, thus being beneficial to improve an aperture ratio and light transmission of the pixel structure.
