Pixel array

A pixel array, comprising a plurality of pixel units, wherein each of the pixel units comprises:

• a scan line and a data line;
• an active device electrically connected to the scan line and the data line;
• a main pixel electrode and a sub-pixel electrode respectively electrically connected to the active device, wherein the main pixel electrode and the sub-pixel electrode are separated from each other;
• a signal line disposed parallel to the scan line;
• a sharing switch device comprising a gate, a source, and a drain, wherein the gate is electrically connected to the signal line, and the source is electrically connected to the active device and the sub-pixel electrode;
• a sharing capacitor electrically connected to the drain of the sharing switch device;
• a first capacitance Cpp, wherein a terminal of the first capacitance Cpp is electrically connected to the source of the sharing switch device and the sub-pixel electrode, and another terminal of the first capacitance Cpp is electrically connected to the main pixel electrode of a next pixel unit;
• and
• a second capacitance Ccc, wherein a terminal of the second capacitance Ccc is electrically connected to the drain of the sharing switch device, and another terminal of the second capacitance Ccc is electrically connected to the main pixel electrode of the next pixel unit, wherein 5%≦(Ccc/Cpp)≦25%.
