A novel soluble compound which is a distyrylarylene derivative having a soluble substituent and a specific central group and having a solubility of 0.5% by weight or greater at 20° C. in an organic solvent; and an organic electroluminescence device having an organic thin film layer which has a single layer or a plurality of layers, is disposed between a cathode and an anode and has at least one layer containing the novel soluble compound. The organic thin film layer can be formed in accordance with a wet process, and the organic electroluminescence device exhibiting a great efficiency of light emission can be produced easily.
A light emitting device includes a first electrode, a second electrode, and at least one emission layer between the first electrode and the second electrode and includes at least one polycyclic compound represented by Formula 1 below, thereby exhibiting long service life characteristics. In Formula 1, the substituents are the same as defined in the detailed description.
