Abstract
A pixel array substrate including a substrate, a first patterned conductive layer, a second patterned conductive layer, and pixel electrodes is provided. The first patterned conductive layer has scan lines and gate electrodes. The second patterned conductive layer has data lines, source electrodes, drain electrodes, and capacitor electrodes. The data lines and the scan lines define many pixel areas. Many pixel storage capacitances Cis formed between the capacitor electrodes and the first patterned conductive layer. Many gate/drain capacitances Cis formed in an overlapping area of the drain electrodes and gate electrodes. A liquid crystal capacitance Cis formed above each pixel electrode. In at least one pixel area, the capacitance ratio of Cand Cis α, the capacitance ratio of Cand Cis β, and the ratio of a first deviation of Cand a second deviation of Cis within the range of α(1+β)(1±50%).
