Abstract
A light-emitting panel including at least a first light-emitting element, each light-emitting element having, between a first conductive film and a second conductive film, a first layer including a metal and a second layer including a light-emitting organic compound. The second 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 first conductive film and the second conductive 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 first conductive film and the second conductive 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.
