Although an ink jet method known as a method of selectively forming a film
of a high molecular species organic compound, can coat to divide an
organic compound for emitting three kinds (R, G, B) of light in one step,
film forming accuracy is poor, it is difficult to control the method and
therefore, uniformity is not achieved and the constitution is liable to
disperse. In contrast thereto, according to the invention, a film
comprising a high molecular species material is formed over an entire
face of a lower electrode connected to a thin film transistor by a
coating method and thereafter, the film comprising the high molecular
species material is etched by etching by plasma to thereby enable to
selectively form a high molecular species material layer. Further, the
organic compound layer is constituted by a material for carrying out
luminescence of white color or luminescence of single color and combined
with a color changing layer or a coloring layer to thereby realize full
color formation.
