Abstract

Diffuseur optique La présente description concerne un diffuseur optique comprenant : - une première couche (202) dans laquelle est formée une piste (120) conductrice électriquement ; et - une deuxième couche (201), sur laquelle repose ladite première couche (202), et dans laquelle sont formés au moins deux piliers (204) conducteurs électriquement s'étendant sur toute l'épaisseur de ladite deuxième couche (201), la deuxième couche (202) comporte au moins une première région (201N) située sous ladite piste conductrice ne comportant pas de pilier.
