Multicolor organic element, method for manufacturing the same, and display using the same

Abstract

A multicolor organic EL element having a light emitting layer containing at least two organic dyes that can act as light emitting center (luminescence center), wherein at least one of said organic dyes is modified so as to change the colors of the light emitted from the element, and a method for manufacturing the element, and a display using the element.

What is claimed is:  
     
         1 . A multicolor organic EL element having a light emitting layer containing at least two organic dyes that can act as light emitting center, wherein at least one of said organic dyes is modified so as to change the colors of the light emitted from the element.  
     
     
         2 . A multicolor organic EL element characterized in that, in an organic electroluminescence element having a light emitting layer composed of at least one layer of an organic compound, said light emitting layer contains three or more organic dyes which can act as light emitting center and which emit at least blue, green, and red light, and that at least one of said organic dyes is modified so as to change the colors of the light emitted from the picture elements.  
     
     
         3 . A multicolor organic EL element charaterized in that, in an organic electroluminescence element having a light emitting layer composed of at least one layer of an organic compound, with said layer containing three or more organic dyes that can act as a light emitting center and that emit at least blue, green, and red light, and with at least one of said organic dyes being modified so as to change the colors of the light emitted from the picture elements, said the picture elements are arranged so as to emit red, green, and blue light by said modification.  
     
     
         4 . A multicolor organic EL element wherein said picture elements are arranged horizontally and in parallel.  
     
     
         5 . A passive-matrix-type RGB dot matrix display, in a multicolor organic EL element according to  claim 3  wherein each pixel is made up of red, green, and blue picture elements, wherein such pixels are arranged horizontally and in parallel, and wherein the light emitting characteristics of each picture element are independently controlled with linear sequential scanning.  
     
     
         6 . An active-matrix-type RGB dot matrix display, in a multicolor organic EL element according to  claim 3  wherein each pixel is made up of red, green, and blue picture elements, wherein such pixels are arranged horizontally and in parallel, and wherein an active element Is added to each picture element to provide a memory function.
