Abstract:
A liquid crystal-containing composition according to the present invention includes a cholesteric liquid crystal, a polymer, and particles having hydrophobic surfaces. The particles having hydrophobic surfaces are at the interface between the region containing the cholesteric liquid crystal and the region containing the polymer.
Abstract:
A liquid crystal-containing composition includes a cholesteric liquid crystal, a polymer, and concave and convex portions located at the interface between a region including the cholesteric liquid crystal and a region including the polymer.
Abstract:
The present invention provides a display medium which prevents a decrease in reflectance during storage at high temperatures, and a writing apparatus using the display medium. A photoconductive layer 24, a selective light transmission layer 22, and a liquid crystal layer 20 are laminated between substrates 12 and 14, which have electrodes 16 and 18, respectively, to form a display medium 10. The selective light transmission layer 22 as a color layer is composed of a deionized material. The ion concentration of the selective light transmission layer 22 is controlled to be within a predetermined range.

Abstract:
A polymer/cholesteric liquid crystal dispersion including a cholesteric liquid crystal dispersed in a polymer. A perpendicular aligning component that aligns the cholesteric liquid crystal in a direction perpendicular to the boundary between the cholesteric liquid crystal and the polymer is provided at least one of at the boundary between the cholesteric liquid crystal and the polymer and in the polymer.
Abstract:
A dispersion liquid including micro-capsules containing a cholesteric liquid crystal as a core material dispersed into a binder resin solution is applied to and dried on a substrate formed an electrode thereon to form a display layer. Then, a light shielding layer is formed and an adhesive layer is formed thereon. On the other hand, a photoconductive layer is formed on another substrate formed another electrode thereon. The substrate formed each layer thereon and the another substrate are bonded to form a display element. The light shielding layer 14 improves roughness on a surface of the display layer and the adhesive layer filled up the roughness. Even if the bubbles occur on a back face of the light shielding layer, the bubbles does not affect the display quality. Because the bubbles are unseen.
Abstract:
