Abstract
A liquid crystal display (LCD) panel with color washout improvement. In one embodiment, the LCD panel includes a common electrode, a plurality of scanning lines, a plurality of data lines, and a plurality of pixels formed by the plurality of data lines crossing the plurality of scanning lines, each pixel comprising two or more sub-pixels, each sub-pixel comprising a sub-pixel electrode, a transistor electrically coupled to a corresponding scanning line, a corresponding data line and the sub-pixel electrode, a liquid crystal capacitor electrically coupled between the sub-pixel electrode and the common electrode, and a storage capacitor, wherein at least one of the storage capacitors of the two or more sub-pixels is electrically coupled between its corresponding sub-pixel electrode and a scanning line immediately prior or next to the corresponding scanning line, and the rest of the storage capacitors of the two or more sub-pixels each is coupled between its corresponding sub-pixel electrode and the common electrode.
