There are provided a phase difference control component, which can realize a liquid crystal display device having a wide angle of visibility, has excellent phase difference symmetry and can realize optical compensation, and a process for producing the same. The phase difference control component comprises a base material; and a phase difference control layer formed of a fixed liquid crystal material provided on the base material through an aligning film and is characterized in that the angle of liquid crystal molecules, present at the interface of the aligning film and the phase difference control layer, to the base material being substantially 0 (zero) degree.

Process for producing a phase difference control component and liquid crystal display device

A method of manufacturing an electrophoretic device includes: forming a partition wall on a one substrate with a predetermined pattern; forming an adhesive layer on the partition wall; filling each region as a cell, which has been partitioned by the partition wall, with a display medium, after having formed the adhesive layer; and adhering the other substrate onto the adhesive layer on the partition wall so as to enclose the display medium. The forming of the adhesive layer is performed, with the use of a transfer film with a heat sealing agent formed thereon, by heat-transferring the heat sealing agent. The adhering of the other substrate includes heating the heat sealing agent for again softening the heat sealing agent, which has been transferred as the adhesive layer, so as to obtain an adhesive force.

Method of manufacturing electrophoretic display device

A display system is built up of at least one display cell including an assembly containing a set of substrates at least one of which is transparent, a wall portion for supporting the set of substrates in opposition to one another defining a liquid confining space, a 1-A electrode and a 1-B electrode located on the side of the substrate facing the liquid confining space in a mutually electrically independent way, an insulating layer for covering the 1-A electrode and the 1-B electrode, an intermediate partition located at a boundary site between the 1-A electrode and the 1-B electrode and the second electrode located on the side of another substrate facing the liquid confining space, such that &#x3b8;1 &#x3c;&#x3b8;2 &#x3c;&#x3b8;3, where &#x3b8;1, &#x3b8;2 and &#x3b8;3 relate to hydrophilicity of the exposed wall portion, hydrophilicity of the intermediate partition, and hydrophilicity of the insulating layer.

Display device and display medium using the same

A display system is built up of at least one display cell comprising an assembly which has at least a first electrode and a second electrode and in which there are mutually non-miscible first and second liquids filled, wherein either one of the first and second electrodes is electrically insulated from the first and second liquids, the first liquid has electrical conductivity or polarity, and voltage is applied to one or both of the first and second electrodes, whereby the first liquid and the second liquid can vary in position to produce a display. Even after an applied voltage is shut off at a position to which the first and second liquids have migrated, the positions of the first and second liquids that have migrated are retained to keep memory capability going on.

Display system, manufacture method thereof and display medium

Display device, its manufacturing method, and display medium

An optical element and a process for producing the optical element are provided. The optical element includes a light transparent substrate and a first birefringence layer provided on the substrate. The first birefringence layer includes a polymerizable liquid crystal having rodlike molecules and a coupling agent and/or a surfactant that homeotropically align the polymerizable liquid crystal to form a crosslinked polymer in a state of homeotropic alignment. The crosslinked polymer has a three-dimensionally crosslinked structure wherein the polymerizable liquid crystal having rodlike molecules holds homeotropic alignment.
