An electroluminescent device

An electroluminescent device has at least first and second light-emitting regions (22,26). The emitter molecules in the first light-emitting region (22) are aligned substantially in a first direction and the emitter molecules in the second light-emitting region (26) are aligned substantially in a second direction, the first direction being different from the second direction. As a consequence of the alignment of the emitter molecules, the first light-emitting region (22) emits light having a first polarisation and the second light-emitting region (26) emits light having a second, different polarisation. Alternatively or in addition, the emitted light may have different wavelengths. Techniques for making the regions (22,26) are described, e.g. by aligning the emitter molecules within a fluid matrix and then fixing the matrix, and by evaporating the emitter molecules perpendicularly onto an alignment layer which itself has been evaporated obliquely onto a substrate.
