摘要： A device is formed by transferring a film onto a substrate when the film requires but the substrate is not adapted to a high temperature heat treatment process. The film having layers and formed on a first substrate having layers is transferred onto a second substrate having layers. The method of transferring the film comprises a first step of forming a lift-off layer and the film to be transferred on the first substrate, a second step of bonding the film to be transferred to the second substrate and a third step of separating the film to be transferred from the first substrate by etching the lift-off layer and transferring it onto the second substrate.

摘要： A ferroelectric liquid crystal device of a cell structure having a suppressed increase of cell thickness along a cell side is constituted by disposing a ferroelectric liquid crystal between a pair of electrode plates each sequentially provided with an electrode, an insulating film and an alignment film on a substrate. The aligment film is provided with a surface unevenness for suppressing a liquid crystal movement causing the increase in cell thickness. The surface unevenness is provided to the aligment film directly or to the insulating film below the alignment film, e.g., by wet forming the relevant film by using at least two solvents having different boiling points or dispersing fine particles within the relevant film, optionally followed by removal of the fine particles.

摘要： A liquid crystal device is formed by a pair of substrates each having thereon electrodes, and a liquid crystal disposed between the substrates so as to be movable along surfaces of the substrates. The liquid crystal is disposed over regions extending between the surfaces of the substrates including an effective optical modulation region, a first peripheral region outside the effective optical modulation region and a second peripheral region formed along a part or an entirety of outer periphery of the first peripheral region. The liquid crystal is disposed to have a higher liquid crystal molecular pretilt angle in the first peripheral region than in the effective optical modulation region. The liquid crystal is disposed in a random alignment state free from uniaxial alignment characteristic or in a layer structure in the second peripheral region. As a result, the liquid crystal molecular movement along the extension of substrates is suppressed in the effective optical modulation region and in the second peripheral region and relatively allowed in the first peripheral region, so that the impurities in the liquid crystal are confined in the second peripheral region while avoiding the liquid crystal thickness irregularity.

摘要： A liquid crystal device, particularly a ferroelectric liquid crystal device, is constituted by disposing a liquid crystal disposed between a pair of rubbing-treated substrates. The uniaxial alignment control force exerted by rubbing is gradually weakened as the rubbing treatment is successively applied to a large number of substrates. This is compensated by varying a rubbing condition, such as a relative moving speed, a rotational speed, or a pressing depth against the substrate of a rubbing roller. Alternatively, such a change in uniaxial alignment control force with time may be utilized for compensating for a difference in uniaxial alignment control force attributable to a difference in stripe electrode extension relative to the rubbing direction.
摘要翻译：液晶装置，特别是铁电液晶装置，通过配置设置在一对摩擦处理基板之间的液晶构成。随着摩擦处理被连续地施加到大量的基底上，通过摩擦施加的单轴取向控制力逐渐变弱。这通过改变相对于摩擦辊的基底的相对移动速度，旋转速度或按压深度的摩擦条件来补偿。或者，可以利用单轴取向控制力随时间的这种变化来补偿归因于条状电极延伸部相对于摩擦方向的差异的单轴取向控制力的差异。
