Abstract
A light emitting device includes a backplane, an array of light emitting diodes attached to a front side of the backplane, a transparent conductive layer contacting front side surfaces of the light emitting diodes, an optical bonding layer located over a front side surface of the transparent conductive layer, a transparent cover plate located over a front side surface of the optical bonding layer, and a black matrix layer including an array of openings therethrough, and located between the optical bonding layer and the transparent cover plate.
