In an embodiment the electroluminescence layer comprises a polymer and an electroluminescent material, wherein the electroluminescent material comprises luminescent centres such as zinc sulphide, dielectric polymer host-binder such as polyurethane, dielectric enhancement additive such as boron nitride.

In an embodiment the electroluminescent material comprises a metal sulphide.

In an embodiment the metal sulphide comprises a zinc sulphide.

In an embodiment the electroluminescent material comprises a mixture of zinc sulphide and a boron nitride.

In an embodiment the polymer comprises polyurethane.

In an embodiment the first electrode and second electrode each comprise an ionically conductive hydrogel and a metal conductor coupled to the ionically conductive hydrogel.

In an embodiment the ionically conductive hydrogel comprises an acrylic acid and a salt mixed into the hydrogel.

In an embodiment the hydrogel comprises a polyacrylic acid (PAA) and a sodium chloride (NaCl) salt mixed with the polyacrylic acid.

In an embodiment the first electrode and second electrode are substantially transparent to allow transmittance of light from the electroluminescence layer outwardly.

In an embodiment the first electrode and the second electrode comprise greater than 96% average transmittance in the range of visible light.

In an embodiment the first electrode, second electrode and the electroluminescence layer are self-repairable such that the function of the electrode and the electroluminescence layer is restored after a deformation, such as a deformation by reforming hydrogen bonds between two adjacent polymer portions.
