Array substrate and manufacturing method thereof, and display device

An array substrate, comprising a peripheral common electrode line for supplying a common voltage and a plurality of sub-pixels, wherein,

• the array substrate further comprises a plurality of first connection portions and second connection portions;
• the first connection portions extend along a first direction and are provided between the peripheral common electrode line and common electrodes of the sub-pixels adjacent to a side of the peripheral common electrode line along a second direction, for electrically connecting the peripheral common electrode line with the common electrodes of the sub-pixels adjacent to the side of the peripheral common electrode line along the second direction;
• the second connection portions extend along the first direction and are provided between the common electrodes of adjacent sub-pixels along the first direction, for electrically connecting the common electrodes of the adjacent sub-pixels along the first direction;
• and
• the first connection portions are separated from each other and the second connection portions are separated from each other so that no continuous common electrode line for supplying the common voltage and extended along the first direction is provided within a display region of the array substrate.
