Document Type and Number:
WIPO Patent Application WO/2023/219169
Kind Code:
A1
Abstract:
Provided is a light emitting device having a plurality of emitted colors that can be manufactured by a simplified process, and in which an increase in the resistance of a second electrode, degradation of optical properties, and uneven luminance can be suppressed. This light emitting device comprises a plurality of sub-pixels that are two-dimensionally arranged and respectively correspond to a plurality of emitted colors, and a connection portion connecting a plurality of different sub-pixels. The light emitting device has a first electrode and, over the first electrode, in order, an organic layer having a light emitting layer and a second electrode. The first electrode and the organic layer are formed in at least each of the plurality of sub-pixels. The second electrode is formed in the plurality of sub-pixels and the connection portion. The connection portion is formed in a part of an inter-sub-pixel region, which is a region between the plurality of sub-pixels. At least a part of the connection portion connects a plurality of sub-pixels of different emitted colors.
