Title:
OPTICAL FILTER CONTAINING SQUARYLIUM DYE-METAL COMPLEX COMPOUND AND FILTER FOR DISPLAY PANEL USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2008/035533
Kind Code:
A1
Abstract:
Disclosed is an optical filer having excellent weather resistance, which enables
good color reproducibility regardless of emission wavelength change in a light-emitting
device due to use environment a color image display, in particular temperature
change in the color image display. Also disclosed is a filter for display panels
using such an optical filter. The optical filter is characterized by containing
a squarylium dye-metal complex compound, which has a maximum absorption in the
visible region while containing a partial structure represented by the general
formula (1) below, and a binder. [chemical formula 1] (1) (In the formula,
M represents a metal atom; A represents an organic group; B represents a five-membered
ring; X represents an oxygen atom, a nitrogen atom or a sulfur atom; Y represents
a nitrogen atom when n = 0, or represents a carbon atom when n = 1; R represents a substituent;
n represents 0 or 1; and m represents an integer of 0-3.)
