Abstract
Official abstract text for this publication.
A technique of manufacturing a display device with high productivity is provided. In addition, a high-definition display device with high color purity is provided. By adjusting the optical path length between an electrode having a reflective property and a light-emitting layer by the central wavelength of a wavelength range of light passing through a color filter layer, the high-definition display device with high color purity is provided without performing selective deposition of light-emitting layers. In a light-emitting element, a plurality of light-emitting layers emitting light of different colors are stacked. The closer the light-emitting layer is positioned to the electrode having a reflective property, the shorter the wavelength of light emitted from the light-emitting layer is.
First claim
Opening claim text (preview).
What is claimed is: 1. A light-emitting device comprising: a first element comprising: a first color filter layer; and a first light-emitting element, wherein the first light-emitting element comprises: a first electrode having a reflective property; a first light-emitting layer over the first electrode having a reflective property; and a second light-emitting layer over the first light-emitting layer, and a second element comprising: a second color filter layer;…
