Patent ID: 7749821

Claim:
A method of fabricating a pixel structure, comprising: forming an active device on a substrate; sequentially forming a first dielectric layer, a second dielectric layer, and a third dielectric layer on the active device and the substrate, wherein etching rates of the first dielectric layer and the third dielectric layer are lower than an etching rate of the second dielectric layer; forming a contact opening in the third dielectric layer, the second dielectric layer, and the first dielectric layer, the contact opening exposing a portion of the active device; patterning the third dielectric layer and the second dielectric layer to form a plurality of stacked structures; forming an electrode material layer covering the plurality of stacked structures, the first dielectric layer, and the contact opening, wherein the electrode material layer located on the plurality of stacked structures and the electrode material layer located on the first dielectric layer are separated; and removing the plurality of stacked structures and the electrode material layer thereon simultaneously to define a pixel electrode and to form at least an alignment slit in the pixel electrode.
