Provided is a light illumination system that, when a short-wavelength light curable resin is applied onto a body to be decorated such as an artificial nail or a nail of a fingertip, easily identifies a coating condition and a color of the short-wavelength light curable resin. This light emission system includes a short-wavelength light emission member and a pseudo natural light emission member, wherein the short-wavelength light emission member has a short-wavelength light emitting source in a casing, the casing has inside an opening that allows insertion of the nail therethrough, the short-wavelength light emitting source irradiates a short-wavelength light curable resin with short-wavelength light having a wavelength less than 410 nm to cure the resin, the pseudo natural light emission member has a planar light source, and the planar light source is located outside the casing and is capable of emitting diffusion light.

Light emission system and pseudo natural light emission member

An organic EL device that efficiently extracts light includes an organic EL element formed by laminating a first electrode layer, functional layer, and second electrode layer on a substrate and a sealing member sealing the organic EL element. The organic EL device has a first electrode communicating part electrically connected to the first electrode layer at one side of the substrate and a second electrode communicating part electrically connected to the second electrode layer at the other side of the substrate. The organic EL device has first cross grooves crossing the organic EL element from the second electrode layer located at the one side to the second electrode layer that is located at the other side. The first cross groove is formed by removing the first electrode layer, functional layer, and second electrode layer. The sealing member and the substrate are connected outside of the first cross grooves.

Organic EL device

The present invention aims at providing an organic EL device that emits light by an alternating current, has a simple structure and provides little increase of production processes, while downsizing an overall configuration and a simplifying a method for producing said organic EL device. The organic EL device includes a power feeding part and an organic-EL-element forming part. The organic-EL-element forming part includes a plurality of unit EL elements formed on a substrate. There is provided a plurality of series-connected parts each formed by a plurality of the unit EL elements that are electrically connected in series in a forward direction. A plurality of the series-connected parts are electrically connected to the power feeding part in parallel. The series-connected parts that are connected in parallel include a series-connected part that is connected to the power feeding part so as to have a reverse polarity.

Organic EL device and method for producing organic EL device

In a device according to the present invention, a first conductive electrode layer being patterned and light transmissive is formed on a light-transmissive substrate and a laminated layer containing a plurality of organic-compound layers is formed so as to cover at least a part of the first electrode layer. The laminated layer is partly removed so that the first electrode layer is partly exposed. At least one layer containing a second conductive electrode layer is formed on the laminated layer and the exposed part of the first electrode layer. A part of the laminated layer and a part of the second electrode layer are simultaneously removed by application of a laser beam from a side of the substrate, so that a plurality of light-emitting sections are electrically connected in series on the substrate.
