COLOR-CORRECTING FILTER AND DISPLAY DEVICE IN WHICH SAME IS USED

摘要

The present invention addresses the problem of providing an inexpensive color-correcting filter and a display device in which said filter is used, said filter efficiently performing separation between blue and green and between green and red, as well as improving color reproducibility. This color-correcting filter is applied in white LEDs, and is characterized in including a substrate that has a resin layer, said substrate containing a dye (A) that has an absorption maximum in the 550-650-nm wavelength region, and a dye (B) that has an absorption maximum in the 420-520-nm wavelength region.
