Abstract
The present invention provides a solid state light-emissive display apparatus of high brightness and efficiency, high reliability, and of thin type, and method of manufacturing the same at low cost. Said apparatus has the luminous thin film made up by laminating or mixing crystal fine particle coated with insulator () of nm size and fluorescent fine particles () of nm size, and the lower electrode and the transparent upper electrode sandwiching said luminous thin film, wherein the electrons injected from said lower electrode are accelerated in the crystal fine particle coated with insulator layer () not being scattered by phonons to become high energy ballistic electrons, and form excitons () by colliding excitation of fluorescent fine particles. Since said fluorescent fine particles are of nm size, the exciton concentration is high, and luminescence intensity by extinction of excitons is also high.
