ABSTRACT:
A liquid crystal display apparatus includes a first glass substrate with signal electrodes arranged in a striped pattern, a second glass substrate with scanning electrodes arranged in a striped pattern, and a ferroelectric liquid crystal between the first and second glass substrates, the first and second glass substrates facing each other and being fastened so that the signal and scanning electrodes cross each other at right angles. Light blocking members functioning as a black matrix are formed on the first glass substrate so that each light blocking member is placed between adjacent signal electrodes, forms a substantially flat surface with the signal electrodes and is partly buried in the first glass substrate. Metal lines are also buried in the first glass substrate so as to be in contact with the signal electrodes. A similar light blocking member is buried between adjacent scanning electrodes and similar metal lines are arranged on the second glass substrate. It is possible to provide for a liquid crystal display apparatus using ferroelectric liquid crystals a substrate structure which does not cause a difference in level on the substrate due to the black matrix. Moreover, the resistance of the signal and scanning electrodes is lowered by the metal lines.
