摘要： An organic electroluminescent display including: a supporting substrate; an organic electroluminescent element; a first passivation layer; a second passivation layer; a color conversion layer for adjusting and/or converting the color of a light emitted from the organic electroluminescent element; and a transparent substrate formed in sequence. Since the display has two passivation layers, a pinhole pass can be effectively blocked, thereby enhancing the sealing properties. Consequently a non-emission region such as a dark spot is hardly formed, and therefore the display can have excellent durability.
