Electroluminescent device having anti-reflective member

A light emitting device having an anti-reflective member. The light emitting device includes an anti-reflective member including a reflective layer and a first electrode; a second electrode; and a light emitting layer disposed between the first electrode and the second electrode. The first electrode of the present invention has both electrode and anti-reflective functions. Ambient light is reflected by the first electrode to obtain a first reflected light and reflected by the reflective layer to obtain a second reflected light. The first reflected light and the second reflected light have phase difference; thus, the reflection of ambient light is reduced.
