Abstract
A luminescent element of a element structure having electrode and, being held between them, a luminescent solution containing a luminescent material and a solvent, wherein the luminescent solution further contains a luminescence promoting additive which comprises a nonionic compound having a diether structure, a crown ether structure or a polyethylene glycol structure and has the function to stabilize the luminescent material being ionized, and the solvent comprises a halogen-containing benzene derivative.

A luminescent element having an element structure in which a luminescent solution containing a luminescent material and a solvent is held between a pair of electrodes, wherein a luminescence promoting additive comprising a nonionic compound which stabilizes the luminescent material is contained in the luminescent solution.
A luminescent element having an element structure in which a luminescent solution containing a luminescent material and a solvent is held between a pair of electrodes, wherein a material which emits light from its triplet state is used as the luminescent material.
A luminescent solution which emits light through application of a voltage while being held between a pair of electrodes, wherein the luminescent solution contains a luminescent material, a solvent and a luminescence promoting additive comprising a nonionic compound which stabilizes the luminescent material.
A process for manufacturing a luminescent element, which process comprises a step of applying a luminescent solution containing a luminescent material, a solvent and a polymerizable substance to a substrate while patterning the solution so that the solution may be divided into every pixel, and a step of polymerizing the polymerizable substance in the luminescent solution applied to allow the luminescent solution to gelate, thereby forming a luminescent section.
A process for manufacturing a luminescent element having an element structure in which a luminescent solution containing a luminescent material and a solvent is held between a pair of electrodes, which process comprises forming each of the pair of electrodes on a substrate, applying a sealing agent to a peripheral portion of each of the substrates, bonding the substrates so that the electrode surfaces are opposed to each other, exhausting air from a hollow portion between the substrates, and injecting the luminescent solution between the substrate.
