Abstract
Provided is a light-blocking pigment composition which has high insulation properties and a low dielectric constant and which can satisfy high optical density, and a light-blocking member for display, which contains the light-blocking pigment composition. When a pigment composition containing a benzimidazolone dioxazine-based pigment, a benzimidazolone-based pigment, and a carbazole dioxazine-based pigment in a specific ratio is used for a light-blocking member for display, since the light-blocking member has high insulation properties, a low dielectric constant, and high optical density, it is possible to provide a display having high light-blocking properties.
