Abstract:
1. A method for manufacturing a pixel structure of a liquid crystal display, the pixel structure comprising a substrate having a control area, a capacitance area, and a display area, the method comprising the steps of: (a) forming a patterned poly-silicon layer on the control area and the capacitance area of the substrate; (b) forming a lower dielectric layer covering the control area and the capacitance area of the substrate, and a first patterned conductive layer on the lower dielectric layer above the patterned poly-silicon layer on the control area and the capacitance area, to form a control device on the control area; (c) forming an upper dielectric layer covering the first patterned conductive layer disposed on the capacitance area of the substrate, and a second patterned conductive layer on the control area and the capacitance area, to form a capacitance device on the capacitance area; (d) forming a patterned planarization dielectric layer and a patterned transparent conductive layer on the control area, the capacitance area, and the display area, to cover the control device and the capacitance device, and to expose at least part of the second patterned conductive layer, the control device, and the capacitance device; (e) forming a third conductive layer on the transparent conductive layer, to electrically connect the exposed second patterned conductive layer, the control device, and the capacitance device; and (f) patterning the third conductive layer and the transparent conductive layer, wherein the third conductive layer electrically connects the second patterned conductive layer, the control device, and the capacitance device.
