Abstract:
The present invention relates to an array substrate of an LCD with a wide viewing angle and a method for manufacturing the same. The array substrate includes: gate lines and data lines formed on a substrate, and TFTs and pixel electrodes formed in pixel areas defined by the gate lines and the data lines, wherein at least one shaft for inducing liquid crystal to form a multi-domain structure is formed on each of the pixel electrodes. The method includes: forming a pattern containing gate lines, gate electrodes, data lines, source electrodes, drain electrodes and TFT channels on a substrate; depositing a passivation layer, opening a first via hole for connecting each of the drain electrodes to each of pixel electrodes and a second via hole for forming a shaft; and depositing a transparent conductive film, forming a pattern containing the pixel electrodes within pixel areas, and forming a shaft at the second via hole for inducing liquid crystal to form a multi-domain structure. The present invention uses a shaft structure to induce liquid crystal to form a multi-domain structure, which not only realizes a symmetric wide viewing angle, but also simplifies the structure and manufacturing process of an array substrate.
