| 摘要 |
<p>The present invention relates to an electrode for an organic light-emitting diode, including in series: (a) a transparent or translucent non-conductive substrate (1), having a refractive index of 1.3 to 1.6; (b) a transparent electrode layer (2), made of a transparent conductive oxide or a transparent conductive organic polymer; and (c) a continuous array of metal lines (3), deposited on the transparent electrode layer (2), characterised in that said electrode layer also comprises (d) as a light-diffusing means, a diffusing translucent layer (4) having a refractive index of 1.7 to 2.4, placed between the non-conductive substrate (1) and the electrode layer (2), and in that the continuous array of metal lines (3) consists, at least on the interface for contact with the transparent electrode (2), of a metal or metal alloy having a reflectivity of at least 80 % on at least one portion of the visible light spectrum.</p> |
