| 1. A light emitting apparatus comprising:
a substrate
light emitting devices corresponding to red, green and blue colors and including light-transmitting anodes and a functional
layer including at least a light emitting layer, the anodes of the red, green and blue light emitting devices being different
thicknesses from each other;
a cathode on an opposite side of the functional layer than one of the anodes;
an optical resonator having a lower-layer-side reflecting layer between the substrate and the one of the anodes; and
a light-transmitting insulating protective film between the one of the anodes and the lower-layer-side reflecting layer to
cover the lower-layer-side reflecting layer.
