  • Pixel unit and liquid crystal display device
    Patent number: 11822189
    Abstract: A pixel unit and an LCD device are disclosed. The pixel unit comprises four sub-pixel units. Each of the sub-pixel units comprises a pixel electrode, comprising a plurality of strip portions positioned at intervals. Two adjacent strip portions define a slit. One strip portion and one slit adjacent to the strip portion are defined as an electrode portion and a width of the electrode portion is a sum of a width of the slit and a width of the strip portion. The width of each of the electrode portions and/or the width of each of the strip portions and/or the width of each of the slits is different. Since the pixel electrodes in different positions have a different aperture ratio-voltage curve. This improves the viewing angle deviation of the four domain pixel electrode.
