<p>The present invention provides a triarylmethane compound and a color filter containing the compound in a blue pixel portion, the triarylmethane compound being capable of providing a colored material which causes a small change in hue over a long period of time even under heat history at a high temperature or under light irradiation. For example, when used for preparing a blue pixel portion of a color filter, the triarylmethane compound is capable of providing a liquid crystal display device or the like which can provide a high-brightness liquid crystal display having excellent brightness over a long period of time even under a high temperature or light irradiation. The triarylmethane compound contains, as a counter anion for a basic triarylmethane dye cation, a heteropolyoxometalate anion represented by (P 2 Mo y W 18-y O 62 ) 6- /6 wherein y = an integer of 1, 2, or 3, and the color filter contains the triarylmethane compound in a blue pixel portion.</p> |
