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.
