Abstract:
1. An organic EL device comprising a substrate having a planar expanse and unit organic EL elements planarly distributed on the substrate, the unit organic EL elements each mainly consisting of at least two electrode layers and an organic light-emitting layer sandwiched between the electrode layers, the device having a plurality of organic EL element belts each formed of a plurality of the unit organic EL elements electrically connected in series so as to extend in a strip-like shape, each of the organic EL element belts having in its longitudinal direction a conductive path through which electric current passes, the organic EL element belts extending in different longitudinal directions and crossing with each other, forming a crossing part, so that the conductive paths cross with each other within the organic EL element belts and within the crossing part, the organic EL element belts crossing with each other in a grid pattern, the organic El device having a non-light emitting region surrounded by the organic EL element belts, the organic EL element belts each being formed of a stack of a substrate-side electrode layer, a functional layer, and a rear face-side electrode layer, and the substrate-side electrode layer having at least one groove dividing the layer, wherein the groove is formed over the non-light emitting region and a region where the organic EL element belt is located.
