    • The present invention relates to an array substrate of TFT-LCD and Method for manufacturing the same. The array substrate includes: gate lines, data lines, pixel electrodes and TFTs formed on a substrate; and a grid graph formed on each of the pixel electrode to make each of the pixel electrodes be simultaneously a built-in polarizer and change natural lights into linear polarized lights. The method for manufacturing an array substrate includes: forming a graph including gate electrodes and gate lines on a substrate; depositing continuously a gate insulating layer, a semiconductor layer and a doped semiconductor layer, and forming graphs of semiconductor layers and doped semiconductor layers above the gate electrodes; forming graphs of source electrodes, drain electrodes, data lines and pixel electrodes, in which a grid graph formed on each of the pixel electrode to make each of the pixel electrodes be simultaneously a built-in polarizer and change natural lights into linear polarized lights. In the present invention, there is no need to attach polarizer of absorption type to the array substrate after being disposed with the color filter substrate as a cell, thereby reducing the production cost of the TFT-LCD, and which is propitious to reduce the thickness of the TFT-LCD and increase the power utilization efficiency greatly of LCD.
    • 本发明涉及TFT-LCD阵列基板及其制造方法。 阵列基板包括:形成在基板上的栅极线,数据线,像素电极和TFT; 并且形成在每个像素电极上以使每个像素电极同时成为内置偏振器并将自然光变成线偏振光的栅格图。 阵列基板的制造方法包括:在基板上形成包括栅电极和栅极线的图形; 连续地沉积栅极绝缘层,半导体层和掺杂半导体层,并且在栅电极上形成半导体层和掺杂半导体层的图形; 形成源电极,漏电极,数据线和像素电极的图形,其中形成在每个像素电极上的栅格图,以使每个像素电极同时成为内置的偏振器,并将自然光变成线偏振光。 在本发明中,在将滤色器基板作为单元布置之后,不需要将吸收型偏振片附着到阵列基板,从而降低TFT-LCD的制造成本,并且有利于减小厚度 的TFT-LCD,大大提高了LCD的功耗利用率。
