Disclosed are a light emitting element that, in the formation of a
plurality of luminescent layers, can effectively suppress color mixing in
each luminescent layer and loss in dissolution of the luminescent layer
per se, and a process for producing the same. The light emitting element
comprising a plurality of luminescent layers formed by photolithography
is produced by a process which comprises: forming a first electrode on a
surface of a base material; forming a first luminescent layer on the
first electrode; conducting treatment for rendering the first luminescent
layer in its exposed area insoluble in a coating liquid for second
luminescent layer formation; forming the second luminescent layer on the
first electrode; repeating the steps a plurality of times to form a
plurality of luminescent layers on the first electrode; and forming a
second electrode on the plurality of luminescent layers.
