Abstract:
1. A black composition comprising as indispensable components titanium nitride oxide particles having a primary particle average diameter of 40 nm to 50 nm, an acrylic resin, carbon black and a solvent, wherein a weight ratio of the titanium nitride oxide to the acrylic resin is within the range of between 75/25 to 60/40; wherein X-ray intensity ratios R 1 and R 2 represented by the Equations (1) and (2) below, respectively, satisfy the relationships represented by Formulae (3) and (4) below: wherein I I I wherein a black coating film obtained from said black composition has an optical density (OD value) of not less than 4.4 per 1 μm of film thickness, wherein the transmittance of i-ray ultraviolet light through a resin black matrix obtained from said black composition is more than 0.2% when the OD value is 2.0, and wherein the minimum exposure energy required for photo-curing is not more than 60 mJ/cm
