Abstract
An electroluminescent device comprises a film containing a phosphor. Means for causing movement of electrons in the film comprising a first layer on one side of the film and a second layer on the other side of the film are provided. The film includes a first material which is also present in the first layer. It has been noted that such a device has enhanced luminescence as compared to a conventional electroluminescent device.
