Array substrate for use in LCD device and method of fabricating same |
摘要 |
A TFT array substrate has a PAI pattern, and the PAI pattern has an over-etched portion of the pure amorphous silicon layer. This over-etched portion prevents a short between the pixel electrode and the pure amorphous silicon layer (i.e., the active layer). The over-etched portion also enables the aperture ratio to increase a gate line over a said substrate; a data line over the said substrate being perpendicular to the gate line; a passivation layer covering the data line, the passivation layer divided into a residual passivation layer and a etched passivation layer; a doped amorphous silicon layer formed under the data line and corresponding in size to the data line; a pure amorphous silicon layer formed under the doped amorphous silicon layer and having a over-etched portion in the peripheral portions, wherein the over-etched portion is over-etched from the edges of the residual passivation layer toward the inner side; an insulator layer under the pure amorphous silicon layer; a TFT formed near the crossing of the gate line and the data line; and a pixel electrode overlapping the data line and contacting the TFT.
