Abstract

An organic EL device includes a reflecting layer which has at least light reflectivity, a first electrode which is arranged on the reflecting layer through a first insulating layer, an organic functional layer which is arranged on the first electrode and includes at least a light emitting layer, a second electrode which is arranged on the organic functional layer and has at least light reflectivity, and a holding capacitance. In the organic EL device, an optical resonator which resonates light from the organic functional layer is formed by the reflecting layer and the second electrode, and the holding capacitance is formed using the reflecting layer, the first insulating layer, and the first electrode.

Dependent claims

An organic EL device comprising:

a base substrate;
a reflecting semi-transmissive layer which is arranged on the base substrate and has light reflectivity and light transmissivity;
a first electrode which is arranged on the reflecting semi-transmissive layer through an insulating layer for each pixel and has light transmissivity;
an organic functional layer which is arranged on the first electrode and includes at least a light emitting layer;
a second electrode which is arranged on the organic functional layer and has light reflectivity;
and
a holding capacitance,
an optical resonator which resonates light from the organic functional layer being formed by the reflecting semi-transmissive layer and the second electrode, and
the holding capacitance being formed using the reflecting semi-transmissive layer, the insulating layer, and the first electrode.
