NEAR-INFRARED SHIELDING FILTER, OPTICAL FILTER FOR DISPLAY, AND DISPLAY AND PLASMA DISPLAY PANEL USING THE FILTER

摘要

PROBLEM TO BE SOLVED: To provide an optical filter for a display having superior infrared-shielding properties and showing superior display characteristics, when it is used in a plasma display panel. SOLUTION: This optical filter for a display comprises a reflection preventing layer and a near-infrared shielding layer. The near-infrared shielding layer contains tungsten oxide and/or composite tungsten oxide, and a compound having maximum absorbance at a wavelength range of 300 to 500 nm. COPYRIGHT: (C)2009,JPO&INPIT
