Title:
PRINTING METHOD OF INK COMPOSITION FOR FORMING PHOTOTRANSFORMATION LAYER, AND COLOR PHILTER
Document Type and Number:
Japanese Patent JP2023092096
Kind Code:
A
Abstract:
To provide: an inkjet printing method which enables uniform discharge of an ink composition for forming a phototransformation layer in a fine subpixel (a pixel portion forming region), which enables high precision printing with good optical characteristics and little variation; and a phototransformation layer having excellent light-emission characteristics and a color filter, which are obtained by such a printing method.SOLUTION: Provided is an inkjet printing method of an ink composition for forming a phototransformation layer, the ink composition containing luminescent nanocrystal particles and a photopolymerizable compound, comprising: a step of reducing an inner pressure by evacuating a deaeration module arranged on the way of an ink passage from an ink tank to an inkjet head; a step of passing the ink composition through the deaeration module; and a step of discharging the ink composition, which passed through the deaeration module, from the inkjet head, where a viscosity of the ink composition at 25°C is 50 mPa s or less.SELECTED DRAWING: None
