Abstract
A pixel structure of a liquid crystal display panel includes a substrate, a switch device, a pixel electrode, an insulating layer, and a patterned common electrode. The switch device and the pixel electrode are disposed on the substrate, and the switch device is electrically connected to the pixel electrode. The insulating layer is disposed on the substrate and covers the switch device and the pixel electrode, wherein the insulating layer includes a plurality of trenches. The patterned common electrode is disposed on the insulating layer and does not cover the trenches. The pixel structure of the liquid crystal display panel and related manufacturing method are able to enhance the driving effect of the liquid crystal molecules, reduce the driving voltage and increase alignment performance of the alignment film.
