LIGHT EMITTING DEVICE AND METHOD OF MANUFACTURE

Title:

LIGHT EMITTING DEVICE AND METHOD OF MANUFACTURE

Document Type and Number:

Japanese Patent JP2004006133

Kind Code:

A

Abstract:

To provide a method of manufacturing a light emitting device improved in emission efficiency, a simple and inexpensive color transformation film, and a color filter.

An organic EL element 27 composed of a lower electrode 24, an organic luminescence medium 25, and an upper electrode 26, and emitting light; and a color transformation film 12 including fluorescence dye transforming light emitted by the organic EL element 27 to light having distinct wavelength are included. The color transformation film 12 is made from an organic EL light emitting device 30 formed by printing by electrophotographic process. Since there is no dye deterioration due to a radical, the color transformation film 12 formed by printing by electrophotographic process can improve the minute performance of the organic EL light emitting element 27.
