    摘要: A liquid crystal device is constituted by a chiral smectic liquid crystal and a pair of substrates sandwiching the chiral smectic liquid crystal therebetween and each having thereon an electrode for applying a voltage to the liquid crystal. At least one of the substrates being provided with an alignment control film comprising a specific aromatic polyimide which has been subjected to a uniaxial aligning treatment. The chiral smectic liquid crystal assumes bistability in a chiral smectic temperature range when incorporated in a test cell which is not provided with an alignment control film and has been subjected to shearing treatment. In the liquid crystal device including the polyimide alignment control film, the chiral smectic liquid crystal at least has a voltage-transmittance characteristic such that an effective tilt angle and a transmittance continuously change depending on an electric field applied thereto.

    摘要: A liquid crystal device has a pair of oppositely disposed substrates and a liquid crystal having chiral smectic C phase disposed therebetween. The liquid crystal is placed in an alignment state in chiral smectic C phase with smectic molecular layers forming a chevron structure. Under no electric field application, the liquid crystal has an average molecular axis substantially in alignment with the uniaxial alignment axis and/or a bisector of a maximum angle formed between two extreme molecular axes established under electric field application, while under electric field application, the liquid crystal provides an effective tilt angle and a transmittance that continuously changes depending on an electric field applied thereto.

    摘要: An electroluminescence device having a layer containing a specific metal coordination compound is provided. The metal coordination compound is represented by formula (1) below: MLmL′n,  (1) wherein M is a metal atom of Ir, Pt, Rh or Pd; L and L′ are mutually different bidentate ligands; m is 1, 2 or 3 and n is 0, 1 or 2 with the proviso that m+n is 2 or 3; a partial structure MLm is represented by formula (2) shown below and a partial structure ML′n is represented by formula (3) or (4) shown below: The metal coordination compound of the formula (1) is characterized by having at least one aromatic substituent for at least one of CyN1, CyN2, CyC1 and CyC2. The metal coordination compound having the aromatic substituent is effective in providing high-efficiency luminescence, long-term high luminance, and less deterioration by current passing.
