Light emitting apparatus including resin banks and electronic device having same
First Claim
1. A light emitting apparatus, comprising:
- a substrate;
a semi-reflection film that reflects at least a part of light;
an organic electroluminescence element including;
a first electrode;
a second electrode having a light reflection property; and
a light emitting layer sandwiched between the first and second electrodes,the first electrode being disposed between the light emitting layer and the semi-reflection film; and
a thickness of the light emitting layer being set so that a first reflection light and a second reflection light interfere and attenuate each other when an external light is incident on the light emitting apparatus, the first reflection light being incident on the light emitting apparatus and reflected by the semi-reflection film, and the second reflection light being reflected by the second electrode.

Abstract
The invention provides an organic EL apparatus including a substrate, a pair of electrodes formed on the substrate, and a light emitting layer disposed between the electrodes is provided in order to implement a light emitting apparatus and an electronic device which decrease reflections in a display of the organic EL apparatus, and to enhance display quality. The substrate includes a transparent substrate, the pair of the electrodes is an anode disposed on the light emitting layer at the substrate side, and a cathode disposed on the light emitting layer at an opposite side of the substrate. A semi-reflection film is disposed near the anode. The semi-reflection film transmits a part of external light incident on the organic EL apparatus from the substrate, and reflects a part of the light other than the light transmitted.
