The sealing glass 8 is adhered to the glass substrate 2 with an adhesive 9. The transparent electrode 4 includes a cathode terminal portion 4a and an anode portion 4
It has b and the anode terminal part 4c. The back electrode 7 is formed so as to partially overlap the cathode terminal portion 4a and is electrically connected to the cathode terminal portion 4a.

なる虞があった。However, since the contact resistance between the cathode terminal portion 4a and the back electrode 7 is high, the voltage applied between the back electrode 7 and the anode portion 4b is low, and the desired light emission brightness is obtained. I had the problem of not being able to do it. This is because at the interface between the back electrode 7 and the cathode terminal 4a, the aluminum of the back electrode 7 is oxidized due to heat generation during energization, and alumina (Al 2 O 3 ) which is an insulator is formed. That is, the oxygen of the oxide (indium oxide and tin oxide) of the cathode terminal 4a made of ITO oxidizes the interface of the back electrode 7 in contact with the cathode 4a, which may increase the electric resistance.
