Abstract
A method of manufacturing a pixel structure of a liquid crystal display panel includes providing a substrate, forming a pixel electrode and a switch device that is electrically connected to the pixel electrode on the substrate, forming an insulating layer that covers the switch device and the pixel electrode on the substrate, forming a common electrode layer on the insulating layer, forming a patterned photoresist layer that includes a plurality of discontinuous patterns on the common electrode layer, performing a first etching process to remove a portion of the common electrode layer so as to forma patterned common electrode, performing a second etching process to remove part of a surface of the insulating layer so as to form a plurality of trenches, wherein the patterned common electrode does not cover the plurality of trenches, and removing the patterned photoresist layer.
