Abstract

An organic EL device includes light-reflective electrodes; light-transmissive electrodes; organic EL layers that are respectively provided between the light-reflective electrodes and the light-transmissive electrodes to emit a plurality of color light components, the organic EL layer emitting a different color light component in each pixel; and transflective layers that are selectively provide in predetermined color pixels to reflect or transmit light emitted from the organic EL layers, respectively, each transflective layer being opposite to the light-reflective electrode with the organic EL layer interposed therebetween.

Claims (21)

1. An organic EL device comprising:

a substrate;

a first light-transmissive electrode formed on or above the substrate;

a second electrode formed above the substrate and the first electrode;

a light-emitting layer arranged between the first light-transmissive electrode and the second electrode, light emitting from the light-emitting layer being emitted from a substrate side;

a light absorption filter that absorbs part of the light emitted from the light-emitting layer that has passed through the first light-transmissive electrode; and

a transflective layer arranged between the light absorption filter and the first light-transmissive electrode,

wherein the light absorption filter is arranged between the first light-transmissive electrode and the substrate.

2. The organic EL device of claim 1 , further comprising:

a plurality of the first light-transmissive electrodes formed on or above the substrate; and

insulation banks arranged between the plurality of first light-transmissive electrodes and formed over edge portions of the first light-transmissive electrodes,

the light absorption filter being formed near the edge portions of the first light-transmissive electrodes covered by the banks in plan view.

3. The organic EL device of claim 2 , further comprising:

transistors connected to the first light transmissive electrodes; and

light-shielding layers arranged under the transistors,

the transistors and the banks being formed so as to overlap in plan view.

4. The organic EL device of claim 1 , the transflective layer being covered by the light absorption filter as viewed from the substrate side.

5. The organic EL device of claim 2 , further comprising:

a portion of the banks being formed between edge portions of the light-emitting layer and the edge portions of the first light-transmissive electrodes.

6. The organic EL device of claim 2 , the banks overlapping edge portions of the light absorption filter in plan view.

7. The organic EL device of claim 2 , the light absorption filter being formed in between the edge portions.
