Abstract
An EL element includes plural light transmitting front-electrodes forming plural lines by wiring and plural back-electrodes forming plural lines by further wiring. The front-electrodes are angled relative to the back-electrodes and a light-emitting layer is disposed between the front-electrodes and the back-electrodes. The EL element combined with a controller works as a lighting unit, which controls light emission at any place, so that a variety of lighting is realized by the lighting unit.
