A light emitting element having a superior light emitting characteristic is provided
by forming a region partly including a phosphor (light emitting region) in manufacturing
of a light emitting element having an organic compound layer using a high molecular
weight material. A solution in which a high polymer having a degree of polymerization
of 50 or more is dissolved in a solvent is applied by a spin coating method, and
then a low polymer which is composed of the same repetition units as the high polymer
and has a degree of polymerization of 2 to 5 and a phosphor are coevaporated to
form a light emitting region (105) and only a low polymer is vapor-deposited
on the light emitting region to form an organic compound layer (103). Thus,
the light emitting region (105) can be partly formed.
