The purpose of the invention is to improve reliability of a light emitting
apparatus comprising TFTs and organic light emitting elements. The light
emitting apparatus according to the invention having thin film
transistors and light emitting elements, comprises; a second inorganic
insulation layer on 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, an anode layer formed on the third
inorganic insulation layer, a second organic insulation layer overlapping
with the end of the anode 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 anode layer, an organic compound layer formed
in contact with the anode layer and the fourth inorganic insulation layer
and containing light emitting material, and a cathode layer formed in
contact with the organic compound layer containing the light emitting
material, wherein the third inorganic insulation layer and the fourth
inorganic insulation layer are formed with silicon nitride or aluminum
nitride.
