ABSTRACT:
A double-sided electroluminescent device emits light from its both sides and has a symmetrically laminated structure. The materials of the insulating layers and the binder of the phosphor layer are the same. The insulating layers and transparent insulating frame form a sealing box to encapsulate the phosphor layer. The bus bars are disposed oppositely in symmetry with respective to the symmetrical plane and a vertical axis of the device. The refractive index of the out most reinforcement layer is higher than that of the substrates.
