Abstract
A method of making black matrix grid lines for a color filter array for use with a liquid crystal display device or the like, comprising providing a photo-thermally sensitive black layer over a support layer; exposing a pattern of electromagnetic radiation onto the photo-thermally sensitive black layer corresponding to the desired pattern of the black matrix grid lines; and peeling off the unexposed portions of the photo-thermally sensitive black layer to thereby form the grid lines.
Claims4
A method of making black matrix grid lines for a color filter array for use with a display device, comprising the steps of:
- (a) providing a photo-thermally sensitive black layer over a support layer;
- (b) exposing a pattern of electromagnetic radiation onto the photo-thermally sensitive black layer corresponding to the desired pattern of the black matrix grid lines wherein the black sensitive layer is colored by carbon particles of one micron or less in size dispersed in a binder;
- and
- (c) peeling off the unexposed portions of the photo-thermally sensitive black layer to thereby form the grid lines.
