Double-face lighting electro luminescent device
First Claim
1. A double-face lighting electro luminescent device comprising a back electrode layer and two lighting sets overlapped with the back electrode layer, the back electrode layer having a first face and a second face opposite to the first face, the two lighting sets being respectively overlapped with the first and second faces, each lighting set being composed of a lighting layer, a front electrode layer and a film-like transparent substrate which are sequentially overlaid on each of the first and second faces, whereby the two front electrode layers and the back electrode layer control the lighting layers of the lighting sets to emit light.

Abstract
A double-face lighting electro luminescent device includes a back electrode layer and two lighting sets. Each lighting set is composed of a lighting layer, a front electrode layer and a transparent substrate which are sequentially overlaid on the opposite faces of the back electrode layer. The back electrode layer is co-used by the two lighting sets. The two front electrode layers and the back electrode layer control the lighting layers of the two lighting sets to respectively emit light.
