Abstract:
1. A method for fabricating an organic electroluminescent display device comprising the steps of: preparing first and second substrates; forming an organic electroluminescent display on the first substrate; forming a first etching mask film on an upper surface of the second substrate; forming a second etching mask film on a lower surface of the second substrate; performing a first etching process on the upper surface of the second substrate to form an etched portion on the upper surface of the second substrate; forming a third etching mask film on the etched portion of the upper surface of the second substrate; performing a second etching process on the etched portion of the upper surface of the second substrate to form a plurality of grooves on the upper surface of the second substrate; removing the first and second etching mask films, the third etching mask film remaining on the etched portion of the upper surface of the second substrate; and encapsulating the organic electroluminescent display between the first and second substrates.
