Description

technical field

[0001] The present invention relates to a black pigment composition and a black coating film-forming composition containing the same, and more particularly to a black pigment composition and a black coating film containing the black pigment composition used for the black column intervals of a flat panel provided, for example, in a liquid crystal display device Form the composition. Background technique

[0002] A liquid crystal display device has a liquid crystal cell structure in which a liquid crystal substance is filled between two glass substrates provided with opposing transparent electrodes. Furthermore, in order to maintain the inter-substrate gap uniformly between the two glass substrates and provide a good image, a post spacer is inserted. Currently, as such a column spacer, a bead spacer such as bead glass can be used. However, in the method of using the bead spacer, it is pointed out that there is a problem that light leakage may occur because th...
