Patent ID: 8120727

Claim:
An array substrate of thin film transistor-liquid crystal display (TFT-LCD), comprising gate lines and data lines formed on a substrate, pixel electrodes set in pixel regions defined by the gate lines and the data lines, and TFTs formed at intersections of the gate lines and the data lines, wherein a grid graph is formed on each of the pixel electrodes to make each of the pixel electrodes be simultaneously a built-in polarizer and change natural lights into linear polarized lights wherein each of the TFTs comprises: a gate electrode formed on the substrate and connected to at least one of the gate lines; a gate insulating layer formed on the gate electrode and the gate lines, and covering the whole substrate; a semiconductor layer and a doped semiconductor layer formed on the gate insulating layer orderly, and located above the gate electrode; a source electrode and a drain electrode formed on the doped semiconductor layer, and forming a TFT channel, wherein the source electrode is connected to at least one of the data lines, and the drain electrode and one of the pixel electrodes located at the same layer therewith are connected as an integrated structure; and a passivation layer formed on the source electrode and the drain electrode.
