  • Patent number: 6368696
    Abstract: A plurality of component layers of thick film forming materials are formed simultaneously on a glass substrate by simultaneously applying a plurality of thick film forming pastes to the glass substrates, or by simultaneously transferring the plurality of component layers of thick laminated film formed on a transfer base sheet from the transfer base sheet to the glass substrate. At least one of the plurality of component layers formed on the glass substrate is patterned, and then the plurality of component layers are burned simultaneously to form a patterned thick laminated film on the glass substrate.

  • Patent number: 5631753
    Abstract: The black matrix substrate used for a flat display such as a liquid crystal display panel, an imager such as CCD or a color filter such as a color sensor comprises a transparent substrate and a light-shielding layer formed on the transparent substrate, and the light-shielding layer contains metallic particles inside thereof, whereby the light-shielding layer can show high light-shielding properties and a low reflectance. In the liquid crystal display panel comprising substrates facing each other and a liquid crystal sealed between the substrates, a semiconductor device provided on one of the substrates has a light-shielding layer which contains metallic particles inside thereof, whereby the semiconductor device can be effectively protected and the liquid crystal display panel has a high contrast.
