Abstract

L'invention porte sur un dispositif d'éclairage qui peut supprimer l'apparition d'une irrégularité de luminosité dans un élément éclairé. Le dispositif d'éclairage par l'arrière (dispositif d'éclairage) (3) est pourvu : d'une pluralité d'ensembles diodes électroluminescentes (4) ; d'une pluralité d'éléments de lentille (6) qui sont disposés, respectivement, en correspondance avec la pluralité d'ensemble diodes électroluminescentes et qui augmentent l'angle de divergence de la lumière rayonnée par les ensembles diodes électroluminescentes. Les éléments de lentille sont disposés de manière à être en oblique par rapport aux ensembles diodes électroluminescentes.
