Abstract

A display unit includes a plurality of light emitting devices, each of the light emitting devices including a function layer including at least an organic layer is sandwiched between a first electrode and a second electrode, and which have a resonator structure for resonating light by using a space between the first electrode and the second electrode as a resonant section and extracting the light through the second electrode are arranged on a substrate, wherein in the respective light emitting devices, the organic layer is made of an identical layer, and a distance of the resonant section between the first electrode and the second electrode is set to a plurality of different values.

First claim

The invention is claimed as follows:

1 . A display unit comprising:
a substrate; a plurality of thin film transistors arranged on the substrate; and a plurality of organic light emitting devices arranged on the plurality of thin film transistors, wherein, the organic light emitting devices comprises:
a first metal layer;
a second metal layer;
a first light emitting layer disposed between the first metal layer and the second metal layer in a first light emission region;
a second light emitting layer disposed between the first metal layer and the second metal layer in a second light emission region; and
a third light emitting layer disposed between the first metal layer and the second metal layer in a third light emission region,
in the first light emission region, the second metal layer is arranged at a first distance from the first metal layer, in the second light emission region, the second metal layer is arranged at a second distance from the first metal layer, in the third light emission region, the second metal layer is arranged at a third distance from the first metal layer, the first distance is larger than the second distance, the second distance is larger than the third distance, and the second metal layer includes silver (Ag) and ytterbium (Yb).
