Abstract: The array substrate comprises a transparent substrate and a film layer which covers the transparent substrate and which is provided with a groove, wherein the film layer is further provided with protrusions which extend from sidewalls of the groove and are away from a bottom surface of the groove; and wherein the groove is used for accommodating frame adhesive. The frame adhesive is injected into a surface of a film layer along the groove, and part of the frame adhesive can flow into the groove and fill the groove. After the frame adhesive is solidified, a clamping connection can be formed between the frame adhesive in the groove and the film layer, so that the frame adhesive and the array substrate can be connected with each other more firmly.
