  • Patent number: 8493536
    Abstract: A liquid crystal display apparatus includes a liquid crystal layer sealed between a first substrate and a second substrate opposed to each other. Inner surfaces of the first and second substrates have been subjected to aligning treatment to splay-align liquid crystal molecules. The liquid crystal display further includes electrodes formed on the inner surfaces of the first and second substrates to generate an alignment transition electric field to cause the liquid crystal molecules to transit from splay alignment to bend alignment. The alignment transition electric field includes a vertical electric field in the thickness direction of the liquid crystal layer, and a horizontal electric field in a direction parallel to the inner surfaces of the first and second substrates to twist the liquid crystal molecules between the substrates.

  • Patent number: 8488413
    Abstract: An indicated position detecting apparatus includes a display module having a display screen, and a plurality of microphones to detect a contact sound to the display screen. The plurality of microphones are arranged at an outer peripheral portion of the display screen to be apart from each other. A time difference acquisition unit acquires arrival time differences of the contact sound between two microphones in each of two combinations of the plurality of microphones. A positional information acquisition unit derives two hyperbolas corresponding to the arrival time differences acquired by the time difference acquisition unit, each hyperbola having focal points at the two microphones in each of the two combinations of the plurality of microphones, and acquires an intersection of the two derived hyperbolas as information of a position where the contact sound is generated.

    Abstract: A liquid crystal display device includes a liquid crystal layer which is arranged between first and second aligning films formed on inner sides of first and second substrates, has liquid crystal molecules twist-aligned in a direction from the first aligning film toward the second aligning film when an electric field is not applied between first and second electrodes, and generates retardation of substantially ?/2 with respect to transmitted light. First and second polarizing plates are arranged on outer sides of the first and second substrates. A transmission axis or an absorption axis of the first polarizing plate is substantially matched with a direction along which the liquid crystal molecules in the vicinity of the first aligning film are aligned when a sufficiently intensive electric field is applied.
