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.
