METHOD FOR MANUFACTURING COLOR CONVERSION SUBSTRATE

摘要

Provided is a color conversion substrate manufacturing method comprising a step of forming at least two kinds of color filter layers for transmitting lights of different wavelength ranges, over a substrate, a step of forming a partition between the color filter layers, a step of forming such a color conversion layer over at least one kind of color filter layer by an ink jet method or an ink dispense method as absorbs a light of a predetermined wavelength and as outputs a light containing a wavelength different from the predetermined one, a step of covering the exposed portions of the partition and the color conversion layer with a protecting layer, and a step of polishing and flattening the partition and the protecting layer. The color conversion substrate thus manufactured by that method is combined with an organic EL element thereby to manufacture an organic EL display. In this case, it is possible to prevent a crosstalk phenomenon and to suppress the optical loss thereby to realize an excellent luminous efficiency of the display.
