Abstract:
1. A display device comprising: a substrate having a display area and a main peripheral area surrounding the display area; a circuit layer on said substrate and having (1) within the display area, a plurality of organic electroluminescence (EL) device components, and (2) within the peripheral area, a driving circuit for the organic EL devices; a first organic insulating film covering said circuit layer; a second organic insulating film covering said first organic insulating film; a separating groove which extends thorough said first and second organic insulating films and which separates each of said first and second organic insulating films into an inner part and an outer part, said groove surrounding said inner parts; an organic electroluminescence (EL) layer in said display area on said inner part of said second organic insulating film and having emission components of said electroluminescence (EL) devices; a first inorganic insulating layer covering said organic electroluminescence (EL) layer, both the inner part and the outer part of said second organic insulating film and a floor and sidewalls of said separating groove; an upper electrode for the organic EL devices between said second organic insulating film and said first inorganic insulating layer, the upper electrode having an end extending from the display area, over said second organic insulating layer, across the floor and sidewalls of said groove, and to the peripheral area, wherein,
