RESIN BLACK MATRIX MATERIAL AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE: A resin black matrix material is provided to have low dielectric constant and high resistance even having moderate optical density. CONSTITUTION: A resin matrix material comprises a mixture containing black pigments and carbon blacks. The black pigment has a content of 20-70 weight% among total solute, and expresses black color. The carbon back has a content of 10 weight% or less among total solute, and complements the black color expressed by the black pigment. The resin matrix material forms a black matrix of which optical density is 1.95 (/um) or more, by controlling the content of the black pigment.
