    摘要: A process for preparing a black matrix comprising the steps of producing a developed substrate by coating, drying, exposing and developing a photoresist on the inside of a substrate, producing a dried substrate by drying the developed substrate several times, coating a dye on the dried substrate and then drying the board, coating graphite on the dried substrate, and etching the graphite-coated substrate. This method makes it possible to perfectly etch the black matrix dot and increase volatility in fluorescent coating.
