摘要： In an electro-optical effect display apparatus, a number of pairs of two parallel and closely disposed scanning bus-lines (21-21, 21-21, . . . ) are disposed on a substrate with a predetermined interval therebetween, and a first electrode bus-line (25) is disposed between each other neighboring two pairs of the scanning bus-lines (21-21 and 21-21). Then respective storage capacitors (26) belonging to two display elements (24, 24), each other neighboring with respect to the first electrode bus-line (25), are connected commonly to the first electrode bus-line (25), thereby utilizing a single first electrode bus-line (25) commonly for two storage capacitors (26, 26) which are disposed substantially symmetrically to the first electrode bus-line (25); and thus, the number of bus-lines can be reduced, and consequently, the area of the display element increases.

摘要： A method of production of active matrix display substrates using thin film transistors and more particularly to a method for production of substrates for liquid-crystal display use. The active matrix substrate using the thin film transistor is produced by the mask processes of smaller number. The process of the present invention can reduce the number of the masks, by one, of the active matrix substrate using the inverted staggered thin film transistor which requires the masks from five levels to six levels. Further improvements reduce the number of the masks to four levels from three levels, thus contributing greatly towards lower cost, improved yield.

摘要： The plasma display apparatus has a noise filter circuit with a noise filter connected to an AC supply disposed at the back side of a plasma display panel. The plasma display apparatus also has a back cover composed of a magnetic metal material disposed at the back side of the plasma display panel to cover the noise filter circuit, wherein magnetic lines of force in a core, made of magnetic material and including the noise filter direct approximately identical to the in-plane direction of the back cover. The configuration can eliminate audible noises because the amount of leakage flux passing through the back cover is reduced.

摘要： An optical switch usable for an optical circuit adapted to be operated by utilizing the electro-optical effect inherent therein. A pair of electrodes are arranged in spaced relation on an optical wave guide which is branched to branch optical wave guides and transmission of light beams is controlled by applying a certain voltage to the electrodes. Both the optical wave guide and the branch optical wave guides are made of electro-optical material. Specifically, the optical wave guides are constituted by a layer of PLZT ((Pb, La) (Zr, Ti) O.sub.3) based thin film which is formed by epitaxial growth on a base plate located on the C-plane of sapphire (.alpha.-alumina). The switch is effective for controlling the transmission of light beams.
