Abstract:
A display device includes a substrate, a plurality of light-emitting elements formed on the substrate, and a reflective layer disposed between the substrate and the light-emitting elements and reflecting the light emitted from the light-emitting elements. The light-emitting elements each include a transparent layer that is in contact with the reflective layer, a light-emitting layer disposed on the upper surface of the transparent layer, and an electrode layer with transparency disposed on a side of the light-emitting layer opposite the side on which the reflective layer lies. The distance between the reflective layer and the electrode layer in each of the light-emitting elements is set such that a light component of a specific color in the light emitted from the corresponding light-emitting layer is enhanced by interference and emitted from the electrode layer. The light-emitting elements include at least first light-emitting elements and second light-emitting elements in which blue and red light components in the light emitted from the light-emitting layers are simultaneously enhanced and emitted from the electrode layers.
Abstract:
A display device includes a plurality of pixels and realizes a color display using emitted light of at least two wavelengths. Each pixel has a microresonator structure formed between a lower reflective film formed on a side near a substrate and an upper reflective film formed above the lower reflective film with an organic light emitting element layer therebetween. A conductive resonator spacer layer is provided between the lower reflective film and the organic light emitting element layer. Light obtained in the organic light emitting element layer is intensified by the microresonator structure in which the optical length is adjusted by the conductive resonator spacer layer and is emitted to the outside.
Abstract:
In a luminous display element, a retro-reflector is provided on the back side of an organic EL layer which includes an emission layer whose state changes between an emission state and a non-emission state. The retro-reflector includes a corner cube array, and reflects incident light in the same direction as an incident direction. A unit structure of the corner cube array is a form of a triangular pyramid which is made up of rectangular equilateral triangles having three faces, and a light shielding process is performed on the periphery of a base angle of the rectangular equilateral triangle. Thus, it is possible to prevent an image from being reflected, so that it is possible to provide the luminous display element whose contrast ratio and the utilization efficiency of emission are high.

A flat display screen includes two electrodes separated by an inner space. At least one first electrode is supported by a thin substrate and by a thick rigidifying plate, the inner space being defined by a peripheral frame placed between the electrodes, outside their useful surface.
Abstract:
An EL lamp includes a transparent electrode, an electroluminescent dielectric layer overlying the transparent electrode, a patterned insulating layer overlies selected portions of the dielectric layer for reducing the electric field across the selected portions of the electroluminescent dielectric layer, and a rear electrode overlying the insulating layer and the electroluminescent dielectric layer. The insulating layer is preferably a low dielectric constant material and can overlie the electroluminescent dielectric layer or can be located between a separate dielectric layer and a phosphor layer. A gray scale is produced by depositing or printing more than one thickness of insulating layer.
