Abstract: A black colorant mixture comprising a bis-oxodihydro-indolylene-benzodifuranone colorant and a perylene colorant is disclosed which provides high blackness and NIR transparency combined with low conductivity for organic coating films used in display devices. Especially, a black matrix for color filter applications and black column spacers are described used in LCD devices. Further, the black colorant mixture can be used in bezels of a display device equipped with a touch sensor.
