PLANAR LIGHT EMITTING DEVICE

摘要

Planar light emitting device includes: anode and cathode feeding parts formed on first surface side of transparent substrate and electrically connected to quadrilateral planar anode and cathode, respectively; quadrilateral frame shaped anode auxiliary electrode formed at the whole circumference of surface of the planar anode; anode feeding auxiliary electrode integrally and continuously formed to the auxiliary electrode and laminated on anode feeding part. Light emitting part is formed of a region where only organic layer intervenes between the planar anode and cathode. Distance between predetermined two parallel sides of the four sides of the light emitting part and the peripheral border of the transparent substrate is smaller than distance between the other two parallel sides and the peripheral border. The cathode and anode feeding parts are located along said other two parallel sides. The anode feeding part is located at each side, in width direction, of the cathode feeding part.
