Abstract
The present disclosure discloses a stretch display device and a preparation method. The method includes providing a substrate on which a flexible substrate is disposed, and a film layer constituting a thin film transistor disposed on a side of the flexible substrate away from the substrate, the film layer being away from the flexible substrate. One side defines a plurality of pixel regions; a hollow portion is formed between adjacent two of the pixel regions, the hollow portion penetrates through the film layer and the flexible substrate; and thermal separation is provided in the hollow portion via a gel; a light-emitting element is disposed in the pixel region, and an encapsulating film layer is disposed on a side of the light-emitting element and the thermal separation gel away from the flexible substrate; heating the thermal separation gel, and the flexible liner. The bottom and the substrate are peeled off. Therefore, when the substrate is peeled off by this method, the problem of breakage of the flexible substrate and the film layer constituting the thin film transistor can be alleviated, and the production yield of the stretch display device can be remarkably improved.
