In-plane switching LCD device comprising common electrode offshoots arranged at two different planes on the lower substrate with the electrode offshoots on higher plane overlapping the ones on lower plane, and having same shapes

An IPS-LCD comprising:

• a lower substrate;
• a plurality of parallel scan lines and a plurality of data lines with equal distances positioned on the upper surface of the lower substrate, wherein the scan lines and the data lines are arranged in a crossing manner to form a pixel matrix, any two of the adjoining scan lines and any two of the adjoining data lines being crossed to define a pixel;
• a plurality of the first electrodes formed in each of the pixels, wherein each of the first electrodes contains a plurality of first electrode offshoots, the first electrode offshoots being arranged parallel with each other in the pixels and at two different planes on the lower substrate, wherein at least one of the first electrode offshoots at the higher plane covers another first electrode offshoot at the lower plane, and the two overlapping first electrode offshoots have same shapes;
• a plurality of capacitor electrodes positioned at the lower plane where some of the first electrode offshoots are positioned, each of the pixels comprising at least one of the capacitor electrodes;
• an insulation layer covering the first electrode offshoots at the lower plane, the capacitor electrodes, and the scan lines;
• a plurality of second electrodes, each of the second electrodes covering at least one of the capacitor electrodes formed in each of the pixels;
• an upper substrate positioned on the lower substrate in parallel with and opposite to the lower substrate;
• and
• a plurality of liquid crystal molecules filled between the lower substrate and the upper substrate;
• wherein an overlapping portion of each of the second electrodes and each of the capacitor electrodes serves as a storage capacitor of each of the pixels.
