    摘要： A light-emitting element and a display device capable of improving the light emission property are provided. Each of a plurality of anode electrodes (11) is provided for a corresponding pixel. The pixel-isolating insulation film (12) has an opening (120) exposing corresponding one of the plurality of anode electrodes (11) to outside, and has an eave (123B) in the middle of a thickness direction of an inner wall of the opening (120). An organic layer (13) includes a CGL (132) cut by the eave (123B) of the pixel-isolating insulation film (12), and covers the opening (120). A cathode electrode (14) is disposed on a surface of the organic layer (13), the surface being a surface on the opposite side of the anode electrode (11).

    摘要： Disclosed herein are a light-emitting device of tip emission type which maintains a stable emission efficiency without leakage current and a process for production of the light-emitting device. The light-emitting device (10) consists of a substrate (1), a lower electrode (4), an organic layer (6) which includes at least an emission layer (6c), and a transparent upper electrode (7) provided on the organic layer (6) which are sequentially formed on top of the other. The lower electrode (4) has a double-layer structure composed of a metallic layer (2a) and a buffering thin film (3c) formed thereon. The buffering thin film (3a) is formed from an oxide of the metallic material constituting the metallic layer (2a), the oxide having a higher conductivity than the organic layer (6), or formed from an oxide of chromium. The thus formed buffering thin film (3a) reduces the surface roughness of the metallic layer (2a) in the lower electrode (4) of double-layer structure. The reduced surface roughness provides a uniform space between the lower electrode (4) and the transparent upper electrode (7).

    摘要： The invention describes an electro-luminescent wire comprising at least two conductors, having substantially longitudinal extensions, parallel to each other and insulated electrically, the conductors being supplied electrically to generate an electromagnetic field therebetween. A luminescent gelatinous substance covers at least one of the conductors and a transparent plastic film encloses the luminescent gelatinous substance and the conductors; the luminescent gelatinous substance emits light in presence of an electromagnetic field generated by the conductors.

    摘要： An object of the present invention is to effectively alleviate surface plasmon absorption at the cathode of an organic EL lighting and improve the light extraction efficiency. An organic EL (electroluminescent) device of the present invention includes a translucent substrate, a transparent electrode, a luminescent layer, and a cathode placed over one surface of the translucent substrate, and a light extraction film having unevenness placed on the other surface. The surface of the cathode facing the luminescent layer has a plurality of recesses or protrusions. The Fourier transform image of the surface of the cathode facing the luminescent layer has a surface plasmon absorption suppression area including a spatial frequency v obtained from Eq. (I) and a light scattering area not including spatial frequencies equal to or greater than the spatial frequency ν.
