Abstract: The present disclosure provides a stretchable film and a fabricating method thereof, and a display device including the same. The stretchable film is composed of at least two layers, where each layer includes a first portion and a plurality of second portions. The first portion is a grid-like structure having a plurality of openings, and the second portion is an island-like structure in the opening. Any one of the plurality of second portions in any one layer does not completely overlap with any one of the plurality of second portions in other layers. The first portions of adjacent layers are partially overlapped, and the overlapped portions are adhered together. The first portion has an elasticity modulus that is less than an elasticity modulus of the second portion.

Abstract: The present invention provides a laser cutting method, a display substrate and a display device. In the laser cutting method, the display substrate and the display device, as a cutting line is defined by two width defining dams on both sides of a region to be cut, the width of the cutting line can be adjusted by adjusting the distance between the two width defining dams. Thus, the width of the laser cutting line is controlled, and the effective use area of the substrate may be saved (and the material may be saved). Meanwhile, as the width defining dams are made of a laser reflective material, a laser beam irradiated onto the width defining dams is reflected without being absorbed by the width defining dams and thus transmitted to a corresponding region on the substrate. As a result, the generation of a carbonization region is avoided.
