Abstract: Disclosed herein are a stretchable display panel and a stretchable device. The stretchable display panel comprises: a lower substrate having an active area and a non-active area surrounding the active area; a plurality of individual substrates disposed on the lower substrate, spaced apart from each other and located in the active area; a connection line electrically connecting a pad disposed on the individual substrate; a plurality of pixels disposed on the plurality of individual substrates; and an upper substrate disposed above the plurality of pixels, wherein the modulus of elasticity of the individual substrates is higher than that of at least one part of the lower substrate. Accordingly, the stretchable display device according to the present disclosure may have a structure that enables the stretchable display device to be more easily deformed when a user stretches or bends the stretchable display device and that can minimize damage to the components of the stretchable display device when the stretchable display device is deformed.

Abstract: Currently described is a display that has a base layer, and on top of that base layer is a buffer layer with two exposed portions. The exposed portions are covered with a film. A pixel layer is placed between the two films, and a first substrate is attached to the pixel layer using an adhesive layer. The substrate is designed using either multiple thicknesses or grooves to facilitate a curvature radius of the end portions of the display to achieve a zero bezel display.
