The purpose of the invention is to improve reliability of a light emitting
apparatus comprising a TFT and organic light emitting elements.The light
emitting apparatus according to the invention having a thin film
transistor and a light emitting element, comprises; a first inorganic
insulation layer on the lower surface of a semiconductor layer, a second
inorganic insulation layer on the upper surface of a gate electrode, a
first organic insulation layer on the second inorganic insulation layer,
a third inorganic insulation layer on the first organic insulation layer,
a wiring layer extending on the third inorganic insulation layer, a
second organic insulation layer overlapped with the end of the wiring
layer and having an inclination angle of 35 to 45 degrees, a fourth
inorganic insulation layer formed on the upper surface and side surface
of the second organic insulation layer and having an opening over the
wiring layer, a cathode layer formed in contact with the wiring layer and
having side end overlapped with the fourth inorganic insulation layer,
and an organic compound layer formed in contact with the cathode layer
and the fourth inorganic insulation layer and comprising light emitting
material, and an anode layer formed in contact with the organic compound
layer comprising the light emitting material, wherein the third inorganic
insulation layer and the fourth inorganic insulation layer are formed
with silicon nitride or aluminum nitride.
