A liquid crystal/polymer composite is sandwiched between a pair of substrates with electrodes, the polymer forms a plurality of column resins, column resins of which the major axis directions substantially agree with the normal direction of the substrate plane and column resins which are aligned on the tilt coexist, the content of the polymer is at least 10 wt %, the alignment of the liquid crystal substantially agrees with the normal direction and the liquid crystal is in a light transmitting state under application of no voltage, and the alignment of the liquid crystal changes and the liquid crystal is in a light scattering state under application of a voltage.

Liquid crystal optical element and process for its production

An image display system includes a screen comprising a pair of substrates with transparent electrodes provided thereon, and a liquid crystal layer sandwiched between the substrates, the liquid crystal layer containing a cured resin and being capable of exhibiting a light transmissive state and a light scattering state; and an image-projecting unit for projecting an image on the screen; wherein a frame comprising a combination of the light transmissive state and the light scattering state as a minimum repetitive satisfies a certain relationship.

Image display system

A liquid crystal/cured composite layer is formed by sandwiching a mixture of a liquid crystal with an uncured curable compound i.e. a curable compound represented by a structure of an acryloyl group-(OR)&#x2014;O-mesogen structural portion-O&#x2014;(RO)-acryloyl group structure (wherein each of Rand Ris a Calkylene group, and each of n and m is from 1 to 10), between a pair of substrates provided with transparent electrodes, and curing the curable compound.

Liquid crystal optical element and method for its production

A driving method for a liquid crystal display device with a cholesteric liquid crystal having a memory mode of operation including a first stage of applying a first voltage to change the state of the cholesteric liquid crystal to a homeotropic state, a second stage of applying a second voltage to change the state of the cholesteric liquid crystal to a homogeneous state or a homogeneous/planar-mixed state, and a third stage of applying a third voltage to change the state of the cholesteric liquid crystal from the homogeneous state or the homogeneous/planar-mixed state to a focalconic state.

Driving method for a cholesteric liquid crystal display device having a memory mode of operation and a driving apparatus

When a new image is written to a liquid crystal panel, row electrodes are scanned a-line-at-a-time in time periods T, T, selected row electrodes are set at a voltage V, and all column electrodes are set at &#x2212;V. The portions of a liquid crystal at the selected row electrodes have a voltage of V+Vapplied thereacross to bring the liquid crystal in the entire screen into a planar state. After the portions of the liquid crystal at all pixels have been brought into the planar state, new display is written by a-line-at-a-time scanning in time periods T, T.
