A black coating composition which gives a highly adhesive resin black matrix that exhibits a high OD value which was able to be attained only by metal thin film black matrices is disclosed. The black coating composition comprises as indispensable components a titanium nitride oxide and a resin. The X-ray intensity ratios Rand Rof the titanium nitride oxide represented by the Equations (1) and (2) below, respectively, satisfy the relationships represented by Formulae (3) and (4) below:+1.8(1.8)}&#x2003;&#x2003;(1)&#x2003;&#x2003;(2)&#x3e;0.70&#x2003;&#x2003;(3)0.85&#x3c;1.80&#x2003;&#x2003;(4)wherein Irepresents the maximum diffraction intensity of the titanium nitride oxide when the angle of diffraction 2&#x3b8;, determined by using CuK&#x3b1; line as the X-ray source, is 25&#xb0; to 26&#xb0;, Irepresents the maximum diffraction intensity of the titanium nitride oxide when the angle of diffraction 2&#x3b8; is 27&#xb0; to 28&#xb0;, and Irepresents the maximum diffraction intensity of the titanium nitride oxide when the angle of diffraction 2&#x3b8; is 36&#xb0; to 38&#xb0;.
