Abstract:
Provided is an organic electroluminescent device including: a substrate (11, 101); a first electrode (12, 102) formed on the substrate (11, 101) and including a pixel region; a partition wall (23, 203) formed on the substrate (11, 101), partitioning the first electrode (12, 102), and including a surface with a recessed and projected form; a luminescent medium layer (19, 109) formed on the pixel region and the partition wall (23, 203), a film thickness of the partition wall (23, 203) being uneven according to the recessed and projected form; and a second electrode (17, 107) formed on the luminescent medium layer (19, 109).
