Abstract: Embodiments of the present disclosure provide a method for fabricating a display panel, a display panel and a display apparatus. The display panel has a display area and an encapsulation area surrounding the display area. In the method, an encapsulating adhesive is formed in the encapsulation area. A portion of the encapsulating adhesive at a corner of the encapsulation area has a recess facing toward the display area. Next, cutting lines are arranged on the encapsulating adhesive. The cutting lines at the corner of the encapsulation area extend into the recess. Next, the display panel is cut along the cutting lines. The method, the display panel and the display apparatus eliminate negative effects of encapsulation reliability test failure due to a portion of the encapsulating adhesive at a corner of the encapsulation area being prone to be cracked, and thus the yield of cutting the display panel is enhanced.
