Abstract: A compact outputter of a simple structure is provided without the back lighting function being deteriorated. A transparent electrode is exposed out of a first surface and a second surface through a through hole of an electro luminescence element. A driving signal output by an LSI chip is directed from a driving signal outputting aluminum electrode to a driving signal inputting transparent electrode through another transparent electrode. The driving signal is input to an LCD panel. Since the LSI chip is mounted on the second surface, the light from the electro luminescence element illuminating the LCD panel is not intercepted.
