    摘要： A photoresist 10 is exposed to light from behind a substrate by using as photomask a wiring electrodes 2 and 4 and a switching element 8 which are individually composed of an opaque member, whereby a passivation layer 9 for the switching element 8 is patterned. By virtue of this method, a photomask becomes unnecessary and jogs of the passivation layer 9 can be formed outside the transparent pixel electrode 7. Therefore, an unsatisfactory orientation of a liquid crystal can be made invisible without enlarging the black matrix of a counter substrate. Furthermore, since a passivation layer can be removed in portions not requiring the passivation layer, image-sticking can be reduced and the quality of displayed picture can be greatly improved. The present invention makes it possible to reduce the number of photomasks used for production of an actively addressing substrate and improve the picture quality of a liquid crystal display.

    摘要： A drive circuit for a liquid crystal display apparatus and a large-sized liquid crystal display apparatus integrated with the drive circuit and having a reduced area occupied by the circuits. The drive circuit includes sample/hold circuits for sampling the input voltage at a predetermined timing, comparator circuits for comparing the output of the sample/hold circuits with the voltage of the signal line VD(i), switches for controlling the output voltage of the signal line, a voltage supply circuit constituted as an image signal control circuit for supplying a voltage to the switches, and control circuits for controlling the switches in accordance with the output of the comparator circuits. For the liquid crystal display panel drive circuit configured as described above, the signal line is controlled by the switches, and therefore the area occupied by the drive circuits can be reduced.

    摘要： A matrix panel display apparatus includes plural signal lines and plural scanning lines intersecting each other and, near each intersection point, a picture element including a picture element electrode, a counter electrode, a display medium disposed between the picture element electrode and the counter electrode, and a transistor for applying image signals from the signal line to the picture element electrode. The transistor is controlled in response to scanning signals received on a scanning line. An auxiliary signal generating circuit generates auxiliary signals for increasing effective voltages of the image signals and applies the auxiliary signals to the picture elements while each of the transistors is in a non-conducting state and each of the picture elements is not selected. Preferably, the auxiliary signal generating circuit applies the auxiliary signals to the picture elements during a predetermined period in which all of the transistors are in the non-conducting state and none of the picture elements is selected.
