An array substrate provided by an embodiment of the present invention may include a flexible substrate and an array layer formed on the flexible substrate. The array layer may includes signal transmission lines, which include a plurality of data lines and a plurality of gate lines intersected with each other on the flexible substrate to form a plurality of sub-pixel regions; and thin film transistors, each of which is provided in a corresponding sub-pixel region of the plurality of sub-pixel regions and connected to a corresponding data line and a corresponding gate line. An angle between at least a portion of the signal transmission lines and any one edge of the flexible substrate may not be substantially equal to 90°.
