ABSTRACT:
A liquid crystal display having an improved display characteristic and having a ring-structured storage capacitor of an independent wiring type wherein disconnection and/or short circuit defects are reduced and a method for manufacturing the same. The liquid crystal display has one or a plurality of first electrodes within each pixel region, for forming one or a plurality of auxiliary capacitors in conjunction with the opposing pixel electrode. The first electrodes surround the pixel electrodes in a ring type structure, and are connected to each other between adjacent pixel portions by at least one wiring connecting portion. The first electrodes are driven independently from the scanning signal lines and the display signal lines. Forming the first electrodes of the capacitors as independent wiring type having a ring structure simplifies the manufacturing process and utilizes the maximum pixel area. Also, the degree of freedom concerning the selection of the driving pulse signal of the liquid crystal display is improved to reduce the R-C delay.
