Patent ID: 8304265

Claim:
A method for manufacturing a color conversion filter, comprising: (a) forming a black matrix having a plurality of openings, on a transparent substrate; (b) independently forming color filter layers including two types of color filter layers, each of the two types of color filter layers including a transmitting portion, disposed over the transparent substrate, that respectively transmits light in a wavelength range different than the other type of color filter layer, and a barrier portion on or over the black matrix, wherein a barrier wall, including a three-layered structure that includes each of the barrier portions of the two types of color filter layers and the black matrix superposed on each other, is formed; and (c) forming a color conversion layer on one of the color filter layers by using an inkjet method, the color conversion layer absorbing light of a specific wavelength, and outputting light comprising a wavelength different from the absorbed wavelength.
