Document Type and Number:
Japanese Patent JP7034584
Kind Code:
B2
Abstract:
A display apparatus includes on a substrate a plurality of light emitting elements in which an organic layer including a white light emitting layer is sandwiched between a lower transparent electrode and an upper electrode, and further includes a reflection layer and an optical interference layer provided between the light emitting elements and the substrate, wherein the optical interference layer is made of a material having a lower refractive index than the refractive index of the light emitting layer and the ratio (nr/nb) of a refractive index (nr) with respect to a red wavelength region to a refractive index (nb) with respect to a blue wavelength region is less than 0.95, and the orders of interference m for blue, green, and red wavelength regions are 5, 4, and 3, respectively, when the optical distance from the light emitting layer to the reflection layer is (2m+1)λ/4±(⅛)λ.
