  • Publication number: 20210071084
    Abstract: The spontaneous orientation aid for a liquid crystal composition provides storage stability and allows liquid crystal molecules to be vertically aligned without a PI layer when added to a liquid crystal composition. When used in a liquid crystal composition, the spontaneous orientation aid can adsorb to substrates sandwiching a liquid crystal composition (liquid crystal layer) and keep the liquid crystal molecules aligned in a vertical direction. The spontaneous orientation aid makes it possible to align liquid crystal molecules without a PI layer (to induce vertical alignment of liquid crystal molecules under no applied voltage and to achieve horizontal alignment of the liquid crystal molecules under an applied voltage).

  • Patent number: 10896241
    Abstract: An information processing apparatus manufactured at low cost and with ease and that is capable of making a search for a ground state of an arbitrary Ising model. An information processing unit containing a plurality of semiconductor chips, each retains a value of one spin or values of a plurality of spins and simulates interactions among the spins, inter-chip wiring between the necessary semiconductor chips, and a control unit that cause each semiconductor chip to perform interaction computation. The control unit converts data of a problem into data of a lattice-shaped Ising model, which is possibly expressed by the plurality of semiconductor chips, without causing a spin arrangement, in a ground state of an Ising model for the problem, to be changed. The data of the lattice-shaped Ising model is divided for allocation to the plurality of semiconductor chips, and causes each semiconductor chip to perform the interaction computation.

    Abstract: The compound is represented by general formula (i). In the compound, in a group Ki1, at least two secondary carbon atoms in an alkyl group (a linear alkyl, halogenated alkyl, or cyanogenated alkyl group having 3 to 40 carbon atoms) are replaced with —C(?Xi1)— and/or —CH(—CN)—, where Xi1 is an oxygen atom, a sulfur atom, NH, or NR13; in addition, a group Ai2, a group Ai3, or the group Ki1 includes, as a substituent, at least one Pi1-Spi1- group, where Pi1 is a polymerizable group, and SPi1 is a spacer group or a single bond. The liquid crystal composition including the compound represented by general formula (i) can be adsorbed onto substrates between which a liquid crystal layer is held, and, consequently, without the use of an alignment film, liquid crystal molecules can be maintained in a state in which the liquid crystal molecules are aligned in a vertical direction.

  • Publication number: 20200087240
    Abstract: A compound represented by formula (i) has, as Ki1 in the formula (i), a structure represented by any one of formula (K-1) to formula (K-3). When used in a liquid crystal composition, it adheres to substrates which hold the liquid crystal composition (liquid crystal layer) therebetween, thereby permitting liquid crystal molecules to be maintained in the state of being aligned in the vertical direction. The liquid crystal composition using the compound enables liquid crystal molecules to be aligned even when the PI layer is not provided (vertical alignment of liquid crystal molecules is induced without the voltage applied and horizontal alignment of liquid crystal molecules is realized with the voltage applied). It is possible to provide a polymerizable compound being excellent in storability and capable of uniform vertical alignment of liquid crystal molecules with no PI layer provided.
