In an organic electro-luminescent display, a pixel circuit is disposed in a unit pixel region defined on a substrate. A passivation layer covers the entire unit pixel region including the pixel circuit. An organic light emitting diode (“OLED”) including a transparent lower electrode formed on a portion of the passivation layer which does not overlap the pixel circuit, an OLED layer, and an upper electrode are sequentially formed on the passivation layer. The transparent lower electrode is a transparent anode of the OLED. A protective layer is formed of the same material as the transparent lower electrode and disposed on a portion of the passivation layer corresponding to the pixel circuit to cover and protect the pixel circuit.

A flat panel display device includes a display area in which a desired image is displayed, and a non-display area arranged outside the display area. The display device includes bank portions arranged on a substrate in a predetermined pattern in the display area and partitioning a plurality of first openings, an emission element arranged at each first opening, dummy bank portions formed in the non-display area together with the bank portions and a sealing passivation layer covering the emission element. The sealing passivation layer consisting of at least a two-layer structure including an organic film and an inorganic film alternately deposited, arranged along a surface defining the dummy bank portions on the upper surface of the emission element, and having a sectional portion directed to and contacting the substrate or a film on the substrate. The flat panel display device of the present invention blocks permeation of harmful material such as moisture or oxygen, thereby preventing degradation of performance of the display device.
