There are provided a light emitting device and an electronic device, which
are light, have low consumption power and a low cost. When an organic light emitting
material (1204b) is included in the positions between the lattices
of a heavy metal complex (1204a) with a lattice structure, the phosphorescence
of the organic light emitting material (1204b) in which only fluorescence
is generally observed can be promoted. Since the organic EL element obtained thus
can utilize phosphorescence, the light emission efficiency is high. Also, since
a conventional organic light emitting material can be used, various light emission
colors are obtained and the organic EL element can be manufactured at a low cost.
A light emitting device and an electronic device are manufactured using such an
organic EL element.
