Abstract

An array substrate and a manufacturing method thereof, and a display device are provided. The array substrate includes a base substrate ( 200 ), gate lines ( 210 ), data lines ( 220 ), a common electrode layer ( 25 ), a plurality of pixels formed by intersecting the gate lines ( 210 ) and the data lines ( 220 ) formed on the base substrate ( 200 ), and an organic film insulation layer ( 260 ) located between the common electrode layer ( 250 ) and a layer on which the data lines ( 220 ) are located. Each of the pixels includes a light transmission area and a light shielding area, in a pattern of the organic film insulation layer ( 260 ), no organic film insulation material exists in the light transmission area, but the organic film insulation material at least remains in areas corresponding to the data lines ( 220 ). With the array substrate, the transmission of the display device is improved without influencing the display quality.
