Organic electroluminescent panel, has extraction layer comprising matrix incorporating reflective particles that are regularly spaced and have size greater than or equal to one micrometer but less than thickness of layer

摘要

The panel has an electroluminescent layer (3) inserted between an opaque layer (2) and an extraction layer (5). The layer (5) has a matrix (51) formed of transparent material and incorporating spherical reflective particles (52). The particles are regularly spaced and have size greater than or equal to 1 micrometer but less than thickness of the layer (5).
