SUBSTRATE BEARING A DISCONTINUOUS ELECTRODE, ORGANIC ELECTROLUMINESCENT DEVICE INCLUDING SAME AND MANUFACTURE THEREOF
First Claim
1. A substrate, for an organic light-emitting device bearing a discontinuous electrode on a main face comprising, in succession, starting from the substrate:
- a contact layer based on a metal oxide;
a metallic functional layer having an intrinsic electrical conductivity property, based on silver, the functional layer thickness being less than 100 nm; and
a work-function-matching overlayer,the electrode having a surface resistance equal to or less than 5 Ω
/□ and
the electrode being in the form of at least one row of electrode zones, with electrode zones having a first dimension (l) of at least 3 cm in the direction (X) of said row, the electrode zones of the row being spaced apart by a distance equal to or less than 0.5 mm, and insulating material filling the space between the electrode zones and projecting beyond the electrode zones.

Abstract
The subject of the invention is a substrate for an organic light-emitting device (10) bearing a discontinuous electrode (2a to 2″c) having a metallic functional layer having an intrinsic electrical conductivity property, between a contact layer and an overlayer, the electrode having a surface resistance equal to or less than 5 Ω/□ for a functional layer thickness of less than 100 nm, the electrode being in the form of at least one row of electrode zones, each electrode zone having a first dimension (l) of at least 3 cm in the direction (X) of said row, the electrode zones of each row being spaced apart by what is called the intra-row distance (d1), this being equal to or less than 0.5 mm. The subject of the invention is also an organic light-emitting device (10) incorporating this electrode and the fabrication of this electrode and of this device.
