Abstract
A light emitting element has been fabricated by making a barrier having a curved surface having a radius of curvature at the upper portion or lower portion, washing a surface of an anode with a porous sponge in order to remove minute grains dotted on the surface of the anode, and performing the vacuum heating in order to remove absorbed water of a whole of a substrate on which a TFT and the barrier have been provided immediately before a layer containing an organic compound is formed.
