In an organic/inorganic composite superlattice type optical modulator capable of entering/projecting light, and capable of modulating an optical characteristic such as transmittance, reflectivity, and a refractive index of light in response to an externally controlled electric field, or light, the organic/inorganic composite superlattice type optical modulator includes at least one type of a compound semiconductor layer and at least one type of an organic compound layer; the compound semiconductor layer and the organic compound layer are alternately stacked in greater than one period; at least one of the compound semiconductor layer and the organic compound layer being crystalline; and also a thickness of each of the layers is made larger than a Bohr radius of the compound semiconductor and smaller than 10 times the Bohr radius. As a result, this novel optical modulator can provide a high nonlinear characteristic by a semiconductor modulator, and a high response characteristic by an organic modulator.

An organic light-emitting diode in accordance with the present invention includes: a reflective electrode; an organic layer formed on the reflective electrode; a transparent electrode formed on the organic layer; a transparent resin layer formed on the transparent electrode; and an encapsulation glass formed on the transparent resin layer. The organic layer includes a light-emitting point. Cone- or pyramid-shaped transparent resin structures are provided in the transparent resin layer in such a manner that each of the cone- or pyramid-shaped transparent resin structures splays from the transparent resin layer toward the encapsulation glass in a normal direction of the encapsulation glass. A refractive index of the transparent resin layer is 1.3 times or more to 1.6 times or less as high as that of the cone- or pyramid-shaped transparent resin structures.

Light-emitting devices (24) and light-emitting displays (1) for realizing bright display by allowing light emitted from an emissive layer (100) to efficiently contribute to a display. Polarization separators (500) are arranged between the emissive layer (100) and a phase plate (700). In the light of a wavelength range which includes a part or all of a light-emission wavelength range of the emissive layer and is narrower than a visible wavelength range and is directed from the emissive layer side to the polarization separators side, the polarization separators (500) reflect circularly polarized light components which are converted into linearly polarized light that is absorbed by the polarizer (600) due to the operation of the phase plate and transmit the other light.

The present invention provides OLEDs of the top emission type comprising organic light-emitting (LE) elements by preventing the problems such as the widening of the power lines, the reduction in the aperture ratio caused by the widening of the upper and the lower capacitor electrodes and the short circuit between the upper and the lower electrodes caused by the roughness of the flattening layers. Two kinds of the OLEDs are provided. One is an OLED comprising a region of LE layer sandwiched between the upper and lower electrodes is formed on a power line of TFT for driving the pixel. Another comprises a region of the LE layer formed on an electrode of capacitor connected to the TFTs to control the light-emitting element. Accordingly, without forming a flattening layer on the light-emitting layer, there is no electric short circuit between the lower electrode and the upper electrode.
