RESIN BLACK MATRIX, LIGHT SHIELDING PHOTOSENSITIVE RESIN COMPOSITION AND LIQUID CRYSTAL DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a resin black matrix excellent in light blocking effect and having such a sufficiently high volume resistivity and a sufficiently low relative dielectric constant as not to cause problems such as a short circuit and malfunction even when formed on a TFT element substrate.

SOLUTION: The resin black matrix has an optical density of ≥3, a volume resistivity of ≥1×1013Ω cm and a relative dielectric constant at 1 kHz of ≤6. The resin black matrix preferably has a crossing angle θ to a substrate of 40-90°. A light shielding photosensitive resin composition for forming the resin black matrix is also provided which contains an alkali-soluble resin, a photopolymerization initiator, an ethylenically unsaturated compound and a light shielding pigment, wherein a content of the light shielding pigment is 30-50 wt.% based on a total solid content and a carbon black is contained as the light shielding pigment in an amount of 2-20 wt.% based on the total solid content.
