Abstract:
A method for forming a self-aligned pixel electrode of a liquid crystal display (LCD), the LCD being formed on a substrate that comprises a plurality of scan lines and a plurality of signal lines perpendicular to the scan lines, the scan lines and the signal lines defining a plurality of adjacent pixel electrode regions on the substrate, the method comprising the following steps:forming a photosensitive material layer on the substrate; removing portions of the photosensitive material layer inside the pixel electrode regions to leave a residual photosensitive material layer on the scan lines and the signal lines, wherein the residual photosensitive material layer is used as a spacer, and a top surface area of the spacer is larger than a bottom surface area of the spacer; and forming a transparent conductive layer on the substrate to cover the spacer and the pixel electrode regions; wherein the transparent conductive layer that covers the pixel electrode regions is separated from the spacer so as to form the self-aligned pixel electrode.
