SUBSTRATE FOR AN ORGANIC LIGHT-EMITTING DEVICE, AND ORGANIC LIGHT-EMITTING DEVICE INCORPORATING IT

摘要

The invention relates to a substrate for an organic light-emitting device (10), comprising a transparent substrate (1) of optical index n0 bearing, on a first main face (11), a transparent or semi-transparent first electrode coating (3), called the bottom electrode, having a sheet resistance less than or equal to 6 O/square and which contains the following multilayer stack: an antireflection sublayer (2) of given optical thickness L1 and optical index n1 such that the n1/n0 ratio is greater than or equal to 6/5; a first metal layer of given thickness e1; a first separating layer of given optical thickness L2; a second metal sheath, having an intrinsic electrical conductivity property, of given thickness e2; and a work-function-matching overlayer, L1 being between 20 nm and 120 nm, L2 being between 75 nm and 200 nm, and the sum of the thicknesses e1 + e2 of the first and second metal layers being less than or equal to 40 nm.
