    • A liquid crystal electro-optical device having gettering means therein and a method for manufacturing such a liquid crystal electro-optical device are disclosed. For example, in a liquid crystal panel disposed in the device, polyvinyl carbazole film is formed as the getting means on at least one of a pair of substrates, and the film has a function to absorb ionized impurities existing in liquid crystal disposed in the device. In virtue of the film, ionized impurities in the liquid crystal layer are decreased, and by heating the liquid crystal panel, the function of the polyvinyl carbazole film, i.e. the function to absorb ionized impurities, is enhanced. Consequently, a liquid crystal electro-optical device free from after-image which was a problem in conventional liquid crystal display devices can be obtained.
    • 公开了一种其中具有吸气装置的液晶电光装置以及制造这种液晶电光装置的方法。 例如,在设置在该装置中的液晶面板中,在一对基板中的至少一个基板上形成聚乙烯基咔唑膜作为取出单元,该膜具有吸收设置在该装置内的液晶中存在的离子化杂质的功能 。 由于薄膜,液晶层中的电离杂质降低,并且通过加热液晶面板,提高了聚乙烯基咔唑薄膜的功能,即吸收电离杂质的功能。 因此,可以获得在现有的液晶显示装置中无问题的无图像的液晶电光装置。

    • An improved liquid crystal device is described such as a display. The device comprises a pair of substrates, a liquid crystal layer, an electrode arrangement, and a ferroelectric film. The ferroelectric film is formed on the inside of the substrate by spining method using a mixture of a ferroelectric material and an organic resin. When coating, the mixture is diluted with a solvent so that the ferroelectric film can be formed as a thin film. In advance of curring, the ferroelectric film is subjected to an electric field and its dipole moment is aligned and fixed in a direction perpendicular to the substrate. In virtue of the dipole moment, the liquid crystal device can be controlled by applying a voltage in one direction with a high stability.
    • 描述了改进的液晶装置,例如显示器。 该装置包括一对基板,液晶层,电极装置和铁电体膜。 通过使用铁电体材料和有机树脂的混合物的旋转法,在基板的内部形成铁电体膜。 当涂布时,用溶剂稀释混合物,使得铁电膜可以形成为薄膜。 在卷曲之前,铁电体膜经受电场,并且其偶极矩在垂直于衬底的方向上对准和固定。 凭借偶极矩,可以通过以高稳定性向一个方向施加电压来控制液晶装置。
