    摘要: An active matrix type liquid-crystal display device wherein a plurality of gate wiring lines and drain wiring lines which cross perpendicularly to each other are laid on a first of two insulating substrates. The gate wiring lines and the drain wiring lines are electrically insulated from each other at areas where they crossover each other and thin-film transistors are respectively arranged near the individual crossover areas with their respective source electrodes connected to corresponding ones of transparent pixel electrodes disposed near the source electrodes, with their respective drain electrodes connected to the drain wiring lines, and with their respective gate electrodes connected to the gate wiring lines. The above structure, which includes the first insulating substrate, is covered with either only alignment layers or both protective insulating layers and alignment layers. Sets of transparent electrodes and alignment layers, each of the sets being opposite to a corresponding one of the transparent pixel electrodes, are disposed on a second of the two insulating substrates, the second insulating substrate being transparent and being located in opposition to the first insulating substrate. A liquid crystal is held between the two insulating substrates. The gate wiring lines as well as the drain wiring lines, and the transparent electrodes which are opposite to the wiring lines on the transparent insulating substrate are connected to liquid-crystal driver circuits which are provided outside the liquid-crystal display device. The improvement to the liquid crystal display device comprises the fact that the drain wiring lines, and the drain electrodes and the source electrodes of the thin-film transistors are formed of the same material as that of the transparent pixel electrodes, and that the transparent pixel electrodes are made thinner than the drain wiring parts.

    摘要: A thermal printing head in accordance with the present invention has a substrate formed of an electrical insulator, heating elements formed on the substrate, and conductive layers formed on the part of the heating elements that is adjacent to and on either side of heat generating portions of the heating elements. The resistivity of heating elements is set at a value of not less than 1000 .mu..OMEGA..cm and, simultaneously, the thickness of conductive layers is set at a value of not more than 300 nm. By virtue of this arrangement, it is possible to reduce the distance between the heat generating portions of the head and the printing paper or ink sheet, and the thin conductive layers contribute to minimizing diffusion of the heat. The thermal printing head is therefore capable of efficiently and accurately transferring heat generated by the heat generating portions to the printing paper or ink sheet. The head is suitable for producing half-tone prints and is capable of producing highly gradated prints such as fully-colored prints.

    摘要: The present invention provides a liquid crystal display device having a large holding capacitance in the inside of a pixel. A liquid crystal display device includes a first substrate, a second substrate arranged to face the first substrate in an opposed manner, and liquid crystal sandwiched between the first substrate and the second substrate. The first substrate includes a video signal line, a pixel electrode, a thin film transistor having a first electrode thereof connected to the video signal line and a second electrode thereof connected to the pixel electrode, a first silicon nitride film formed above the second electrode, an organic insulation film formed above the first silicon nitride film, a capacitance electrode formed above the organic insulation film, and a second silicon nitride film formed above the capacitance electrode and below the pixel electrode. The second silicon nitride film is a film which is formed at a temperature lower than a forming temperature of the first silicon nitride film. The first silicon nitride film and the second silicon nitride film form a contact hole therein by etching both of the first silicon nitride film and the second silicon nitride film collectively by dry etching. The second electrode and the pixel electrode are connected to each other via the contact hole. A potential different from a potential applied to the pixel electrode is applied to the capacitance electrode, and a holding capacitance is formed by the pixel electrode, the second silicon nitride film and the capacitance electrode.
