Abstract

Disclosed is an electroluminescent display device () comprising a plurality of pixels () disposed on a substrate (), each pixel being formed by one or more basic emitting zones (), every basic emitting zone having a base electrode () disposed on said substrate () and an OLED stack () comprising an electroluminescent layer disposed on said base electrode (), the device () further comprising a common electrode () disposed on top of the OLED stack, said device being characterized in that: —two adjacent base electrodes () belonging to two adjacent basic emitting zones () are separated by a filler element having an insulating surface () which fills the zone () between said adjacent base electrodes () and electrically insulates them from each other; at least the surface of said filler element having an insulating surface () in contact with the base electrodes () is made of an insulating material; a separator () is situated above the filler element () and separates the electroluminescent layers of the OLED stack () from two adjacent basic emitting zones ().
