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 / 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.
