Claim Text:
1. A flexible organic electroluminescent device, comprising: a substrate having a display area including a plurality of pixel regions and a non-display area at an outside of the display area; each pixel region of the plurality of pixel regions comprising: a switching thin film transistor and a drive thin film transistor formed on the substrate; an insulating layer on the substrate including a first organic layer and an inorganic layer on the first organic layer, wherein the insulating layer covering the switching thin film transistor and the drive thin film transistor exposes a drain electrode of the drive thin film transistor; a first electrode on the inorganic insulating layer, connected to the drain electrode of the drive thin film transistor; a bank formed on the substrate around each pixel region covering edges of the first electrode; an organic light emitting layer formed on the first electrode; a second electrode formed on the organic light emitting layer and on an entire surface of the display area; and a second organic layer formed on an entire surface of the second electrode, wherein each bank is separated from the bank of an adjacent pixel region of the plurality of pixel regions.
