Claim:
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: R 1 =I 3 /{I 3 +1.8( I 1 +1.8 I 2 )} (1) R 2 =I 2 /I 1 (2) 0.70 <R 1 ≦0.82 (3) 0.85 <R 2 <1.80 (4) wherein I 1 represents the maximum diffraction intensity of the titanium nitride oxide when the angle of diffraction 2θ, determined by using CuKα line as the X-ray source, is 25° to 26°, I 2 represents the maximum diffraction intensity of the titanium nitride oxide when the angle of diffraction 2θ is 27° to 28°, I 3 represents the maximum diffraction intensity of the titanium nitride oxide when the angle of diffraction 2θ is 36° to 38°, and 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 2 .
