Zusammenfassung:	A light-emitting device having a plurality of leads, a body, a light source die, a dark layer, and a substantially transparent encapsulant is disclosed. The dark layer absorbs a substantial portion of ambient light. The light source die may be a top emitting die. The light-emitting devices may be suitable for applications such as a large scale electronic display where each pixel is represented by each light-emitting device. The dark layer may contribute towards high contrast ratio by absorbing substantial amount of ambient light falling thereon.
