GLASS SUBSTRATE WITH AN ELECTRODE, ESPECIALLY A SUBSTRATE INTENDED FOR AN ORGANIC LIGHT-EMITTING DIODE DEVICE

摘要

Glass substrate (1) having a first face (10) and an opposed second face (11), said substrate being provided on its second face with an electrode (2) formed from at least one electrically conducting layer, characterized in that it has, over its entire second face and with a thickness e extending towards the interior of the substrate in the direction of the first face (10), a variation of the refractive index of the glass obtained by an ion exchange treatment, the refractive index on the surface being higher than that of the glass located away from the thickness.
