Organic electro-luminescent display panel

A method for manufacturing an organic electroluminescent display panel to produce said organic electroluminescent display panel provided with a transparent insulating substrate, an organic electro-luminescent device formed on said transparent insulating substrate and a sealing cap hermetically containing said organic electro-luminescent device to form sealed space enclosing hygroscopic agent in cooperation with said transparent insulating substrate, said method comprising:

• a process of preparing an air-permeable sheet provided with a gluing agent layer covered with released paper on its surface;
• a process of partitioning a region of said gluing agent layer into a first gluing agent region for sticking said hygroscopic agent in powder or grain form and second gluing agent region for bonding said air-permeable sheet to said sealing cap;
• a process of peeling off a portion of said released paper covering said first gluing agent region to expose said first gluing agent region and sticking said hygroscopic agent in powder or grain form to exposed said first gluing agent region;
• and
• a process of peeling off a remaining portion of said released paper to expose said second gluing agent region and bonding said air-permeable sheet with said hygroscopic agent being stuck to said sealing cap with exposed said second gluing agent region sandwiched between said air-permeable sheet and said sealing cap.

• a process of preparing an air-permeable sheet with a gluing agent layer mounted on a surface of said air-permeable sheet;
• a process of partitioning a region of said gluing agent layer into a first gluing agent region for sticking said hygroscopic agent in powder or grain form and second gluing agent region for bonding said air-permeable sheet to said sealing cap;
• a process of holding a mold member to said second gluing agent region with said first gluing agent region being left exposed and sticking said hygroscopic agent on exposed said first gluing agent region to said first gluing agent region;
• and
• a process of making said second gluing agent region exposed by removing said mold member and bonding said air-permeable sheet with said hygroscopic agent stuck to said sealing cap with exposed said second gluing agent region sandwiched between said air-permeable sheet and said sealing cap.
