The invention provides a device to be used for a liquid crystal display including (a) a pair of substrates A and B facing to each other, (b) a plurality of electrodes formed in electrical connection with the substrate A, (c) sealing material for adhesively connecting the substrates A and B at margins thereof to each other so that the substrates A and B are spaced away from each other, (d) liquid crystal filled in a space formed between the substrates A and B, and (e) black matrix formed on the substrate B. The black matrix is formed with at least one opening so that the sealing material can make direct contact with a surface of said substrate B, the opening having a width smaller than a width of the electrodes. |

DETAILED DESCRIPTION In view of foregoing problems of prior devices, it is an object of the present invention to provide a device to be used for a liquid crystal display, which device has an increased adhesive strength at marginal sealing portions and hence higher reliability.
The present invention provides a device to be used for a liquid crystal display including (a) a pair of substrates A and B facing to each other, (b) a plurality of electrodes formed in electrical connection with the substrate A, (c) sealing material for adhesively connecting the substrates A and B at margins thereof to each other so that the substrates A and B are spaced away from each other, (d) liquid crystal filled in a space formed between the substrates A and B, and (e) black matrix formed on the substrate B, the black matrix being formed with at least one opening so that the sealing material can make direct contact with a surface of the substrate B, the opening having a width smaller than a width of the electrodes.
The present invention further provides a device to be used for a liquid crystal display including (a) a pair of substrates A and B facing to each other, (b) a plurality of electrodes formed in electrical connection with the substrate A, (c) sealing material for adhesively connecting the substrates A and B at margins thereof to each other so that the substrates A and B are spaced away from each other, the sealing material containing light-impermeable pigment dispersed therein, (d) liquid crystal filled in a space formed between the substrates A and B, and (e) black matrix formed on the substrate B, the black matrix being formed with at least one opening so that the sealing material can make direct contact with a surface of the substrate B, the opening having a width smaller than a width of the electrodes.
In a preferred embodiment, the black matrix is formed with the same number of openings as that of the electrodes.
The opening or openings is (are) preferably in alignment with one or each of the electrodes
