摘要:
An improved liquid crystal device and manufacturing method for same are described. In the device, a pair of substrates, between which a liquid crystal layer is disposed, is joined with pillars inbetween functioning as spacers which are provided of photocurable resin by photolithography. With this structure, the spacers can be in surface contact with the inside surfaces of the substrates on which electrode arrangement and active devices are formed.
摘要:
An improved liquid crystal filling device is shown. Prior to joining a substrate with another substrate between which the liquid crystal is to be charged, the liquid crystal is dropped on the substrate and then the other substrate is superimposed on the substrate under pressure. Sandwiched between the substrates, the liquid crystal spreads at high temperature.
摘要:
An improved liquid crystal device immune to contamination of the liquid crystal is shown. The liquid crystal is isolated from ion sources such as glass substrates, transparent electrodes or so on by means of a nitride layer positioned therebetween.
摘要:
A liquid crystal device including a unipolar driving source; a pair of substrates, at least one of which is transparent; a chiral smectic liquid crystal layer interposed between the substrates; and an electrode arrangement provided in order to apply an electric field normal to the liquid crystal layer, wherein the opposed inner surfaces of the substrates contiguous to the chiral smectic liquid crystal layer are formed of different materials having different surface energies such that upon application of the unipolar voltage to the chiral smectic liquid crystal, the chiral smectic liquid crystal molecules will be placed in a first state and upon removal of the unipolar voltage, the liquid crystal molecules will be returned to a second state.
摘要:
An improved liquid crystal device which is driven by applying electric field thereon is shown. The liquid crystal is contained in the device as a layer which is separated into pixel and the optical condition of which is changed by the electric field applied. Contiguous to the liquid crystal layer, a ferroelectric film is provided to impart hysteresis to the device.

摘要:
A liquid crystal electro-optical device has electrodes, a pair of substrates at least one of which is transparent, thin-film transistors provided on one of the pair of substrates, and a ferroelectric or antiferroelectric liquid crystal material, or a ferroelectric or antiferroelectric liquid crystal material mixed with a polymer compound held between the pair of substrates. A particular relationship is established between spontaneous polarization of the liquid crystal material, a capacitance between pixel electrodes, a pulse voltage applied to gates of the transistors, a time constant of a pixel, a residual pixel voltage immediately before application of the next pulse, and other parameters.
摘要:
A liquid crystal display of the chiral smectic type is caused to have grey scales, by applying a voltage of an intermediate level to the liquid crystal. Within each picture element of the display, there are a number of domains of the liquid crystal layer, some being transparent while the other being opaque rendering grey tone to the picture element.

摘要:
The liquid crystal display according to this invention comprises a liquid crystal cell having a pair of substrates with faced insides which are provided with electrodes, ferroelectric liquid crystal with a chiral smectic C phase in between said substrates and a polarizing plate on the light incidence side. One of said electrodes is a relfective electrode. The display is utilized with microcomputers, word processors, television or so on, and wherein, due to a small number of parts, the absorption loss of light is small and a reflective plate is prevented from being oxided and therefore degraded in reflection index, since it is not exposed to air.
