A method for producing a pattern of an electroconductive member, comprises: a step of forming on a substrate surface a resin film containing acid group; a step of incorporating into the resin film a liquid containing a metal complex salt and having a pH value of 5 to 7; and a step of baking the resin film to form the electroconductive member from a metal component incorporated into the resin film, thereby improving uniformity and speed of an adsorbing of the metal component into the resin, and providing uniform characteristics of the electroconductive pattern.

In regard to an electroconductive pattern including a high resistivity region partially, by forming a pattern with a photosensitive resin, making the pattern absorb liquid containing a metal component, and baking this, an electroconductive film of metal oxide is formed, this electroconductive film is further covered by a gas shielding layer, and portions which are not shielded are reduced selectively to be made low resistance metal film regions. Since the material which constitutes the electroconductive pattern is hardly removed, a load concerning material reuse is mitigated and material cost is reduced.

A liquid crystal device is constituted by a chiral smectic liquid crystal to form a plurality of pixels. The chiral smectic liquid crystal has a temperature-dependent tilt angle characteristic satisfying the following relationship: Ĥ10−Ĥ1≦4.0 degrees, wherein Ĥ10 denotes a tilt angle at a temperature which is 10° C. lower than an upper limit temperature of chiral smectic C phase and Ĥ1 denotes a tilt angle at a temperature which is 1° C. lower than the upper limit temperature. The liquid crystal is aligned to provide an average molecular axis to be placed in a monostable alignment state under no voltage application, is tilted from the monostable alignment state in one direction when supplied with a voltage of a first polarity at a tilting angle which varies depending on magnitude of the supplied voltage, and is tilted from the monostable alignment state in the other direction when supplied with a voltage of a second polarity opposite to the first polarity at a tilting angle, said tilting angles providing maximum tilting angles formed under application of the voltages of the first and second polarities, respectively, different from each other,and one of said tilting angles continuously changing depending on magnitude of the supplied voltage of the first polarity or the second polarity.

In a liquid crystal apparatus the scanning electrodes are applied with at least two scanning selection signals in at least two vertical scanning periods. The scanning selection signals comprise mutually different waveforms, each comprising a pulse of one or the opposite voltage polarity with respect to the level of a voltage applied to a scanning electrode when it is not selected. Data pulses are applied to the data electrodes in phase with the pulse. A writing voltage and a fore voltage are applied prior to the writing voltage formed by the combination of the pulse and a data voltage to a pixel on a scanning electrode during a selection period determined by application of the one or the opposite polarity to the scanning electrode. The fore voltage pulse has a polarity opposite to that of the writing voltage and an amplitude which is 1/2 or less of that of the writing voltage.
