The electrode structures in the display units of the liquid crystal display (LCD) panel described in the embodiments of the invention are formed by stacking the bottom electrodes, the insulation pattern layers, and the top electrodes. The width of each of the bottom electrodes is greater than the width of each of the top electrodes (i.e., the electrode structures have the protrusion-like shape). Therefore, the operating voltage can be effectively reduced, and the transmission rate can be improved.
