A light emitting device and display apparatus using a plurality of light emitting devices can drastically reduce contrast loss due to light from an external source. The light emitting device has a light emitting chip(s) and a first layer covering the light emitting chip(s). A second layer including a light scattering material is provided at least over the first layer, and the surface of the second layer has a plurality of protrusions which follow the topology of the light scattering material. The display apparatus is formed by disposing these light emitting devices in an array on a substrate.
