Definitions
- the present invention relates to an anthracene derivative and an organic electoluminescence device using the anthracene derivative, and in particular, a long-life organic electoluminescence device capable of obtaining uniform light emission over a long period of time and a novel anthracene for realizing the same. It relates to derivatives.
- Organic electoluminescence (EL) devices use the principle that a fluorescent substance emits light by recombination energy of holes injected from an anode and electrons injected from a cathode by applying an electric field. Self-luminous element. Report of low-voltage driven organic EL devices using stacked devices by Eastman Kodak's CW Tang et al.
