Estimating the term…
A spin coatable, photosensitive black matrix coating having high surface resistivity and exhibiting an optical density greater than 3 at film thicknesses of ≦1 micron has been developed for flat panel display applications where a chrome/chrome oxide black matrix is usually employed. It possesses excellent thermal, light, and chemical stability and good shelf life. It is deposited and patterned by a simple photolithographic processes excellent thermal, light, and chemical stability and good shelf life. It is deposited and patterned by a simple photolithographic process, thereby reducing the cost of processing in relation to chrome/chrome oxide black matrix fabrication processes.
In a photosensitive black matrix composition comprising a polymer binder, a pigment, and a dye dissolved or dispersed in a solvent system, the improvement being that said dye comprises an azo-metal complex dye.
In a photosensitive black matrix composition comprising a polymer binder dissolved or dispersed in a solvent system, the improvement being that said composition further comprises an azo-metal complex dye, a coupling agent, and a metal oxide pigment.
The combination of a substrate having a surface and the composition of claim 50 applied to said substrate surface.
