Abstract

See full text

A display device includes a first support plate. A pixel region is positioned over the first support plate. The pixel region includes a pixel and an electrode layer disposed between the first support plate and the pixel region. A specular reflective layer is disposed on the electrode layer. The specular reflective layer has a first refractive index. A diffusion layer is disposed on the specular reflective layer. The diffusion layer includes a plurality of islands. Each island of the plurality of islands is separated by a distance from an adjacent island of the plurality of islands, wherein a portion of the specular reflective layer is exposed between two adjacent islands of the plurality of islands. Each island has a second refractive index greater than the first refractive index.
