Light-emitting panel, and method for manufacturing such panel

摘要

A light-emitting panel includes at least a first light-emitting element emits and a second light-emitting element, each light-emitting element having, between a reflective film and a semi-transmissive/semi-reflective film, a layer including an optical adjustment layer and a light-emitting organic compound interposed between a pair of electrodes. One of the light-emitting elements further includes a layer transmitting red light provided over the corresponding semi-transmissive/semi-reflective film. The layer having the organic compound emits light having a wavelength between 600 nm and 800 nm, and light having a wavelength between 400 nm and 600 nm. The distance between the reflective film and the semi-transmissive/semi-reflective film in one of the light-emitting elements being N/2 (where N is a natural number) of a length between 600 nm and 800 nm, and the distance between the reflective film and the semi-transmissive/semi-reflective film in the other one of the light-emitting elements being N/2 (where N is a natural number) of a length between 400 nm and 600 nm. The light-emitting panel might further include a third light-emitting element and a fourth light-emitting element.

1. A light-emitting panel comprising:
a first light-emitting element: and a second light-emitting element, wherein the first light-emitting element and the second light-emitting element each comprises, between a pair of a reflective film and a semi-transmissive and semi-reflective film, a layer containing a light-emitting organic compound interposed between a pair of electrodes and an optical adjustment layer, wherein the layer containing a light-emitting organic compound in each of the first light-emitting element and the second light-emitting element emits light comprising light with a wavelength greater than or equal to 600 nm and less than 800 nm and light with a wavelength greater than or equal to 400 nm and less than 600 nm, wherein the first light-emitting element has an equal optical path length between the pair of the reflective film and the semi-transmissive and semi-reflective film of N/2 (N is a natural number) of a length greater than or equal to 600 nm and less than 800 nm, wherein a layer transmitting red light is provided over the semi-transmissive and semi-reflective film in the first light-emitting element, and wherein an optical path length between the pair of the reflective film and the semi-transmissive and semi-reflective film in the second light-emitting element is N/2 (N is a natural number) of a length greater than or equal to 400 nm and less than 600 nm.
