Title:

LIGHT-BLOCKING PIGMENT COMPOSITION AND LIGHT-BLOCKING MEMBER FOR DISPLAY

Document Type and Number:

WIPO Patent Application WO/2015/136814

Kind Code:

A1

Abstract:

Provided are: a light-blocking pigment composition capable of satisfying the properties of high insulation, low dielectric constant, and high optical density; and a light-blocking member for use in a display and containing the light-blocking pigment composition. It is possible to provide a display having high light-blocking properties resulting from high optical density, and also having high insulation properties and a low dielectric constant, by using a pigment composition containing a benzimidazolone dioxazine pigment, a benzimidazolone pigment, and a carbazole dioxazine pigment in specific proportions in a light-blocking member for use in a display.
