COMPOUND AND COLOR FILTER

There is provided a triarylmethane compound which can provide a colored product that has light resistance equivalent to heretofore available light resistance and that undergoes only a small change in hue over a long period of time even when having a high-temperature heat history. For example, when a...

More Information
Summary:There is provided a triarylmethane compound which can provide a colored product that has light resistance equivalent to heretofore available light resistance and that undergoes only a small change in hue over a long period of time even when having a high-temperature heat history. For example, when a blue pixel portion of a color filter is formed, there is provided a triarylmethane compound which can provide a liquid crystal display apparatus or the like that has light resistance equivalent to heretofore available light resistance and that can perform high-brightness liquid crystal display for a long time even at high temperature. There is also provided a color filter containing the triarylmethane compound in the blue pixel portion. In the triarylmethane compound, the counter-anion of a basic triarylmethane dye cation is a heteropolyoxometalate anion represented by (SiMoW 11 O 40 ) 4- /4. The color filter contains the triarylmethane compound in a blue pixel portion.
