Abstract
An organic EL light emitting device, in which a plurality of divided light emitting segments are connected in series, is efficiently manufactured without separate coating of organic EL light emitting layers with the use of a vapor-deposition mask. Conductor parts 5 are respectively formed on first electrodes 2b and 2c in boundary parts of adjacent light emitting segments a, b and c. Organic light emitting layers 3a to 3c and second electrode 4a to 4c are respectively stacked on each of the first electrode 2a to 2c. The conductor part 5 has a function for electrically connecting the first electrodes and the second electrodes in the adjacent light emitting segments, whereby the light emitting segments are connected in series.
