Black pigment dispersion composition and black pigment dispersion resist composition containing the same

Abstract

The invention provides a black pigment dispersion composition with excellent dispersion performance, high surface resistance, high infrared transmittance and good shading performance, and a black pigment dispersion resist composition containing the same. Specifically, the black pigment dispersion composition contains a pigment A containing a to d: a. Lactam black; b. Purple pigment; c. Blue pigment and / or green pigment; and d. Carbon black.

Description

technical field [0001] The present invention relates to a black pigment dispersion composition and a black pigment dispersion resist composition containing the same, which are used for liquid crystal display elements (formation of black matrix of liquid crystal panels, coloring pitch, and light-shielding parts of organic EL display devices), Solid-state imaging devices (image sensors (image sensors) represented by CCD and CMOS), infrared transmission (IR-Pass) dispersion liquids used in infrared sensors, etc., have excellent dispersibility, and OD value, surface resistance value and infrared Higher transmittance and good light-shielding properties. Background technique [0002] The liquid crystal method is often used in image display devices such as computers, color TVs, mobile phones, tablet devices, and game terminals. A liquid crystal image display device displays images on a screen using color filters forming pixels of each color and liquid crystals that function as shu...

Problems solved by technology

However, when using a variety of organic pigments, it is difficult to obtain good dispersibility due to differences in the characteristics of the pigment surface and the problem of high OD values ​​that have been required in recent years.
