Abstract
A light emitting element and a flat panel display that includes the element has a diamond film, which can achieve a stable and strong light emission with low electricity consumption. The light emitting element has a multilayer structure with an optional base material, a lower electrode, a diamond film, a fluorescent thin film, an upper electrode, and an upper electrode for wiring purposes. Under a proper biasing voltage between the lower and upper electrodes, carriers (either electrons or holes) are injected from the lower electrode to the diamond film, and are accelerated in the diamond film, so as to excite the fluorescent thin film and cause the thin film to fluoresce.
Claims26
A light emitting element comprising:
- a lower electrode;
- a diamond film formed on a surface of said lower electrode and configured to transport carriers injected from said lower electrode;
- a fluorescent film formed on a surface of said diamond film and configured to fluoresce due to excitation by the carriers injected from the lower electrode and through the diamond film;
