Title:
LIGHT-SHIELDING PIGMENT COMPOSITION AND LIGHT-SHIELDING MEMBER FOR DISPLAY
Document Type and Number:
WIPO Patent Application WO/2016/076028
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a light-shielding pigment composition having a highly insulative property, a low dielectric constant, a high optical density, and being capable of stably driving a liquid crystal display device; and a light-shielding member for a display using said light shielding pigment composition. It was found that the light-shielding member for a display has a highly insulative property, a low dielectric constant, and a high light-shielding property by using a pigment composition including a zinc phthalocyanine pigment having a specific structure as an essential component together with an organic pigment having a color of orange, yellow, purple, or the like, and the present invention was thereby completed.
