Method of fabricating an organic light emitting device

An object of the present invention is to reduce or eliminate the occurrence of a variety of failure modes (shrink, dark spot and the like) in a light emitting element having an organic compound. The present invention suppresses a non-light emitting region generated immediately after a light emitting element has been fabricated by making the barrier 111 have a curved surface having a radius of curvature at the upper portion or lower portion, washes the surface of the anode 110 with a porous sponge in order to remove minute grains dotted on the surface of the anode, and suppresses the occurrence of a shrink by performing the vacuum heating in order to remove absorbed water of a whole of the substrate on which a TFT and a barrier have been provided immediately before the layer 112 containing an organic compound is formed.
