[Problem] To provide an organic electroluminescent device that is excellent in external extraction efficiency of emitted light and able to attain reduced power consumption and prolonged service life. [Solution] An organic electroluminescent device including, in an order mentioned: a reflective electrode; an organic electroluminescent layer; a transparent substrate; and a light-extracting unit, wherein the light-extracting unit contains a light-extracting member and a light distribution-converting member. In one preferable embodiment, the light-extracting member and the light distribution-converting member are each a prism, a prism array, a lens, a lens array, a fine concavo-convex structure or a fine particle layer.

Organic electroluminescent device

[It is an object] to provide an organic electroluminescent element having a transparent electrode, with which there is no need to produce a separate light extraction layer, [which can be produced by] a simple film formation process, and which is advantageous in terms of cost. [This is] an organic electroluminescent element in which a substrate, a first transparent electrode that is adjacent to this substrate, an organic layer including at least one organic light-emitting layer, a second transparent electrode, a low refractive-index layer with a refractive index of 1.3 or less, and a reflector layer are formed in this order, with this organic electroluminescent element being such that the aforementioned first transparent electrode contains at least one type of transparent particle with a primary particle size of 0.5 &#x3bc;m or more.

Organic electroluminescent devices

Provided is an organic electroluminescent device including, in an order mentioned: a reflective electrode; an organic electroluminescent layer; a light extraction layer; and a transparent substrate, wherein a ratio (w/d) is 9 or more where 'd' denotes a total average thickness from the organic electroluminescent layer to the transparent substrate and 'w' denotes a minimum width of a non-light-emitting region present outside of an outer periphery of an effective light-emitting region in the organic electroluminescent layer.

It is an object of the present invention to provide an organic electroluminescent element with which no light extraction layer needs to be produced separately, which has a transparent electrode that is advantageous in terms of cost and can be formed by a simple film formation process, and which is excellent from the standpoint of light extraction efficiency. The present invention provides an organic electroluminescent element in which a substrate, a first electrode adjacent to this substrate, an organic layer including at least one organic light-emitting layer, and a second electrode adjacent to this organic layer are formed in this order, with this organic electroluminescent element being such that at least one of the aforementioned electrodes is a transparent electrode which is transparent, which contains at least one type of light scattering particles that are transparent and that have a primary particle size of at least 0.5 &#x3bc;m, and which is composed of the aforementioned light scattering particles and a component having a refractive index equal to or higher than the refractive index of the aforementioned organic light-emitting layer.

An imaging apparatus includes a solid state imaging device having a light receiving characteristic in which an amount of light received reaches a maximum when an angle of incidence of parallel light, radiated at continuously changing angle, is not vertical (angle &#x3b8; of incident light in the range of 3&#xb0; to 15&#xb0;) to a light receiving surface. This characteristic changes the amount of light received greatly when an aperture stop is opened, and enhances an opening/closing effect of the aperture stop. The solid state imaging device includes a core/clad light guide path structure, whose core serves as a light guide path. This light guide path includes a columnar portion located above a photodiode, and a lens portion on the columnar portion.

A mass spectroscopy device constituted by a first reflector which is partially transparent and partially reflective, a transparent body, and a second reflector which is reflective. The first reflector and the second reflector are arranged on opposite sides of the transparent body so as to form an optical resonator in such a manner that when a specimen containing an analyte subject to mass spectroscopy is arranged in contact with a surface of the first reflector, and the surface is irradiated with measurement light, optical resonance occurs in the optical resonator, and intensifies an electric field on the surface, and the intensified electric field desorbs the analyte from the surface.
