Display device and a method of manufacturing the display device
First Claim
1. A display device having a light-emitting element, the light-emitting element having a lower electrode, an upper electrode, a functional layer, and a cavity portion in which light generated in the functional layer is resonated, in which a pixel is formed of a set of at least three light-emitting elements corresponding to different wavelength, whereinthe optical distance of the cavity portion in a first light-emitting element is made equal with the optical distance of the cavity portion in a second light-emitting element, and the optical distance of the cavity portion in the first light-emitting element is made different from the optical distance of the cavity portion in a third light-emitting element.

15. A method of manufacturing a display device having a pixel comprising three resonance type light-emitting elements corresponding to the wavelengths for red, blue, and green, wherein the method includes the steps of:
-
forming a lower electrode on a substrate, forming a transparent layer corresponding to red and a transparent layer corresponding to blue each at an identical height on the lower electrode and forming a transparent layer corresponding to green at a height different from the transparent layers corresponding to red and blue, forming a functional layer by successively laminating a plurality of light emitting units that emit lights at different wavelengths above the transparent layers corresponding to each of red, blue, and green, and forming an upper electrode above the functional layer. - View Dependent Claims (16)
