Abstract
To improve an optical property of a near-infrared-absorbing PDP filter and suppress a manufacturing cost. The present invention provides a dispersion liquid for near-infrared-absorbing adhesive-body. The dispersion liquid includes, in a solvent, one or more types of nanoparticles selected from a tungsten oxide nanoparticle and a composite tungsten oxide nanoparticle, and an acryl-based polymer dispersant is added to the dispersion liquid. The average dispersed nanoparticle diameter of the tungsten oxide nanoparticles and the composite tungsten oxide nanoparticles is equal to or smaller than 800 nm.
