Abstract

In this display, an upper electrical insulation layer covers the active matrix; each electrooptic element comprises a lower supply electrode that is applied to this insulation layer. According to the invention, this lower electrode includes an organic conducting layer applied directly to said insulation layer and a metal layer covering the organic conducting layer.Such a structure makes it possible to optimize both planarization and light extraction by an optical cavity effect thereby improving the performance of the display.
