Patent ID: 8274219

Claim:
An electro-luminescent display panel, comprising: an active device array substrate comprising a plurality of pixel electrodes, a plurality of scan lines, a plurality of data lines, and a plurality of active devices; a pixel definition layer disposed on the active device array substrate, wherein the pixel definition layer comprises a plurality of openings exposing the pixel electrodes, respectively; a plurality of electro-luminescent devices disposed in the openings and on the pixel electrodes, respectively; an electrode layer disposed on the pixel definition layer and the electro-luminescent devices; and a protective layer disposed on the electrode layer, comprising: a buffer layer disposed on the electrode layer; a first encapsulation film disposed on the buffer layer, the first encapsulation film comprising a plurality of island patterns located above the pixel electrodes, respectively, wherein the plurality of island patterns are not overlapped with the plurality of data lines; and a second encapsulation film disposed on the buffer layer and the first encapsulation film, wherein a WVTR of the first encapsulation film is about 0.1 g/m 2 /day to about 100 g/m 2 /day, and a WVTR of the second encapsulation film is about 1 g/m 2 /day to about 50 g/m 2 /day.
