ELECTROLUMINESCENT ELEMENT STRUCTURE HAVING FERROELECTRIC ELECTRON DISCHARGING AGENT

摘要

PURPOSE: An electroluminescence device structure is provided to have a stable and big current even in a low acting voltage by accelerating injected electron into an electroluminescent layer. CONSTITUTION: The electroluminescence device is composed of: the first insulating layer formed on a silicon substrate; the first electrode(3) formed by metal film on the upper part of the first insulating layer; a ferroelectric layer(4) formed over the first electrode and working as an electron generator if feeding the pulse voltage of the positive voltage and the negative voltage that have a regular period, to the first electrode; and a second electrode(5) formed on the upper part of the ferroelectric layer having a regular interval.
