Abstract: The invention is for a process for manufacturing a liquid crystal display element for use in a color display using resist materials. The process comprises forming a transparent conductive film on one side of a transparent substrate; patterning the transparent conductive film by coating with a colored positive resist followed by exposure and development, coating a black-colored negative resist onto the transparent film; forming black stripes by subjecting the negative resist to exposure from the back side of the transparent substrate and development of the negative resist.

Abstract: A method for manufacturing a color liquid crystal display device is available where light-blocking layers are provided for the color filter stripes on a pixel-by-pixel basis by inserting the light-blocking layers between stripes of transparent conductive films that are already striped as scanning electrodes. The manufacturing method is characterized by the steps of the formation of a transparent conductive film on a first transparent substrate, patterning of the transparent conductive film by coating the transparent conductive film with a colored, positive resist, exposure and development, coating of patterned transparent conductive films with a blackened, negative resist, formation of black stripes of the negative resist between the patterned transparent conductive films by performing back exposure through the first transparent substrate and development, and the removing the positive resist remaining on the patterned transparent conductive films.

Abstract: A large number of liquid crystal display devices is formed on a single plane, each of the liquid crystal display devices being formed by arranging liquid crystal between transparent substrates which allow light from a light source to pass through. Display portions of the respective liquid crystal display devices are covered by a masking member (23) and a light guide which is formed of light guide devices, one or more of which being provided for each of said liquid crystal display devices, and junctions between the liquid crystal display devices are also covered by the light guide. With this structure, when the light guides are formed such that the junctions between the plurality of liquid crystal display devices are also covered, lattice-like non-display lines do not appear, thereby providing substantially visually uniform brightness throughout the entire screen of the large-sized liquid crystal display and improving the entire image.

Abstract: This invention provides a humidity sensor having a negative coefficient of resistivity for relative humidity, which comprises 99.99 to 10 mole percent of iron oxide (Fe.sub.2 O.sub.3) and 0.01 to 90 mole percent of at least one member selected from alkali metal oxides, which are lithium oxide (Li.sub.2 O), sodium oxide (Na.sub.2 O), potassium oxide (K.sub.2 O) and cesium oxide (Cs.sub.2 O). The amount of the alkali metal oxide in the sensor is preferably 0.01 to 25 mole percent. This sensor is advantageous because it can accurately detect the changes in humidity and it has a long, stable life.

Abstract: A voltage-dependent resistor comprising a sintered body consisting essentially of ZnO, as a main constituent, and, as additives, bismuth oxide (Bi.sub.2 O.sub.3), titanium oxide (TiO.sub.2) and one or two members selected from the group consisting of aluminum fluoride (AlF.sub.3), chromium fluoride (CrF.sub.3), nickel fluoride (NiF.sub.2) and strontium oxide (SrO) with electrodes applied to the opposite surfaces of the sintered body.

Other additives such as cobalt oxide (CoO), manganese oxide (MnO), barium oxide (BaO), boron oxide (B.sub.2 O.sub.3), chromium oxide (Cr.sub.2 O.sub.3), nickel oxide (NiO) and germanium oxide (GeO.sub.2) improve the voltage nonlinear property of the sintered body.
