  • Patent number: 7561244
    Abstract: A liquid-filled container (1) comprises a first and a second sheet (3, 5) between which a thin film of liquid (7) is dispersed. Supporting members, (9), which extend from the first sheet to the second sheet, are covalently bonded to the first and the second sheet to make the container mechanically robust. In an advantageous embodiment, the thin film of liquid, the supporting members and the second sheet form, in combination, a stratified-phase-separated composite. The liquid-filled container is particularly suitable for use in a liquid crystal display.

  • Patent number: 7311948
    Abstract: The invention pertains to an isosorbide derivative having at least one polymerizable group, characterized in that the isosorbide derivative further comprises at least one photo-convertible group for adjusting the helical twisting power of the isosorbide derivative. According to a preferred embodiment the isosorbide has the formula wherein A stands for a bond or a p-phenylene group; B and B? are independently O—(CH2)oO—CO—CR??CH2, o being 2-12 and R? being H or CH3; P stands for a CH2 or a C?O group; Q and Q? are independently selected from H, C1-C3 alkyl, C1-C3 alkoxy, halogen, and CN; n is an integer from 1 to 3; and m is an integer from 0 to 2.

  • Patent number: 6795149
    Abstract: This invention relates to a liquid crystal display device, comprising at least one retardation film (4), a nematic liquid crystal layer (5), and a light reflecting RGB patterned cholesteric color filter (6), for reflecting either essentially left-circular or right-circular polarized light, being characterized in that said liquid crystal layer (5) is a super twisted nematic liquid crystal layer having a twist angle in the interval 180-270 degrees, and in that the summed retardation R of the retardation film or retardation films and the liquid crystal layer is equal to approximately R=(3+2n)&lgr;/4, where n=0,1,2,3 . . . .
