摘要： The present invention provides an array substrate and a manufacturing method thereof. The array substrate of the present invention comprises multiple pixel units arranged in an array, each pixel unit comprising a substrate, an active layer, a source layer and a drain layer arranged in the same layer, and a gate layer; wherein each pixel unit further comprises a power wire layer connected to the source layer via a via hole. Since the power wire layer of the present invention is separately provided as a layer, the area of the projection of the power wire layer on the substrate may be larger, that is, the conductive cross-sectional area of the power wire layer may be larger, and thus the resistance of the power wire layer is decreased. Therefore, difference among currents of different pixel units is reduced, and thus the mura phenomenon generated in displaying is alleviated.
摘要翻译：本发明提供一种阵列基板及其制造方法。本发明的阵列基板包括排列成阵列的多个像素单元，每个像素单元包括布置在同一层中的基板，有源层，源极层和漏极层以及栅极层; 其中每个像素单元还包括通过通孔连接到源层的电力线层。由于本发明的电源线层分别设置为层，所以电源线层在基板上的投影面积可以较大，即电力线层的导电截面积可能较大因此功率线层的电阻降低。因此，不同像素单位的电流之间的差异减小，从而减轻了显示中产生的色调现象。
