Array substrate and manufacturing method thereof, display panel and display apparatus

摘要

The present invention provides an array substrate and a manufacturing method thereof, a display panel and a display apparatus. The array substrate comprises: a base substrate; and a pixel region and a periphery region formed on the base substrate, wherein the periphery region is located around the pixel region, the pixel region comprises an amorphous silicon thin film transistor, and the periphery region comprises a low temperature poly-silicon structure. As the a-Si thin film transistor is used in the pixel region of the array substrate, the problem that there is a too large leakage current in the pixel region of the LTPS array substrate in the prior art is overcome, the leakage current in the pixel region is reduced, while as the LTPS structure is used in the periphery region of the array substrate, a narrow frame of the display panel and the display apparatus may be achieved.
