Abstract
Official abstract text for this publication.
An organic optical device which can suppress deterioration due to moisture or an impurity is provided. An organic optical device includes a supporting body, a functional layer provided over the supporting body, and a light-emitting body containing an organic compound provided over the functional layer. The functional layer includes an insulating film containing gallium or aluminum, zinc, and oxygen. The supporting body and the functional layer each have a property of transmitting light with a wavelength of greater than or equal to 400 nm and less than or equal to 700 nm. By using the insulating film containing gallium or aluminum, zinc, and oxygen as a protective film, entry of moisture or an impurity into an organic compound or a metal material can be suppressed.
First claim
Opening claim text (preview).
What is claimed is: 1. An organic optical device comprising: a supporting body; a functional layer comprising an insulating film, over the supporting body; and a light-emitting body comprising an organic compound, over the functional layer, wherein the insulating film comprises a composition of gallium, zinc, and oxygen, wherein the insulating film comprises at least one of a Ga—Zn—O-based material, a Ga—Zn—O—N-based material, a Ga—Al—Zn—O-based material, and a Ga—Al—Zn—O—…
