Abstract:
To provide a light-emitting panel in which the occurrence of crosstalk is suppressed. To provide a method for manufacturing a light-emitting panel in which the occurrence of crosstalk is suppressed. The light-emitting panel includes a first electrode of one light-emitting element, a first electrode of the other light-emitting element, and an insulating partition which separates the two first electrodes. A portion with a thickness A1 smaller than a thickness A0 of a portion of the layer containing a light-emitting organic compound, which overlaps with a side surface of the partition, is included. The ratio (B1/B0) of a thickness B1 of a portion of the second electrode, which overlaps with a side surface of the partition, to a thickness B0 of a portion of the second electrode, which overlaps with the first electrode, is higher than the ratio (A1/A0).
