    Abstract: The contrast of an electroluminescent display using an organic EL layer (6) is improved by using a circular polariser (14) in front of the surface. The polariser causes ambient light to be absorbed (LT, LR) while allowing transmission of emitted light (LE) and therefore improves the contrast of the display.

    Abstract: A method of making a light emitting device comprises the laminating together of two self-supporting components, at least one of which has a light emitting layer (12) on an inner surface thereof. A first self-supporting component is formed by coating a first substrate (10) with an organic light emissive material (12). A second self-supporting component is formed by coating a second substrate (2) with an organic material which is one of a light emissive material and a charge transport material (8). The two self-supporting components are laminated together such that the organic materials (8, 12) are located between the substrates (2, 10) in the finished device.

    Abstract: A display comprises a light modulator defining an array of pixels arranged in rows (2) and columns (3) and addressable to select between at least an opaque state for each pixel and a transparent state for each pixel. The display includes a light emitting device arranged adjacent the light modulator to act as a light source for the display. The light modulator is a passive matrix liquid crystal display device and the light source is an electroluminescent LED. The light source is addressable to emit light from selected regions LER, each region overlapping at least a plurality of rows (2) of the light modulator. In this way, the problem of electrical cross-talk in the display is reduced.
