Abstract: An array substrate and manufacturing method thereof, and a display device are provided. The array substrate comprises a TFT, an isolating layer (M), a pixel electrode (12) and a via (Q) formed through the isolating layer (14). A drain (6) of the TFT is electrically connected with the pixel electrode (12) through the via (Q). A first light blocking layer (14a) is formed on the pixel electrode (12) inside the via (Q). In the array substrate of the present invention, display effect deterioration due to the light reflection on pixel electrode inside the via is avoided by forming the light blocking layer on the pixel electrode inside the via. At the same time, prior to manufacturing the light blocking layer, a barrier layer is formed first to guarantee no residual of light blocking layer will be left on the substrate, thereby improving display performance of the display device.

Abstract translation: 提供阵列基板及其制造方法以及显示装置。 阵列基板包括TFT，隔离层（M），像素电极（12）和通过隔离层（14）形成的通孔（Q）。 TFT的漏极（6）通过通孔（Q）与像素电极（12）电连接。 在通孔（Q）内部的像素电极（12）上形成第一遮光层（14a）。 在本发明的阵列基板中，通过在通孔内部的像素电极上形成遮光层，避免了通孔内的像素电极的光反射引起的显示效果劣化。 同时，在制造遮光层之前，首先形成阻挡层，以确保不会在基板上留下残留的遮光层，从而提高显示装置的显示性能。
