  • Patent number: 11150520
    Abstract: Each pixel has a reflection region to produce a display in reflection mode. The first substrate includes: a pixel electrode for each pixel; and a first vertical alignment film. The second substrate includes: an opposite electrode opposite the pixel electrodes; and a second vertical alignment film. Of the first and second vertical alignment films, only the second vertical alignment film exerts an alignment-regulating force that determines a pretilt angle. Each pixel electrode includes a plurality of subpixel electrodes. The opposite electrode has an opening in an area corresponding to one of four corners of at least one of the plurality of subpixel electrodes. Liquid crystal molecules in a thickness-wise middle portion of the liquid crystal layer on the subpixel electrode are oriented toward the opening.

  • Publication number: 20210286279
    Abstract: A magenta toner is provided. The magenta toner comprises toner particles each comprising a binder resin and a colorant. From 1.0% to 25.0% by number of the toner particles have a CH rate of 25.0% or more in absolute value. The CH rate is calculated from the following formula (1): CH rate (%)=[(In?Iave)/Iave]×100??Formula (1) where, in a Raman spectrum of each toner particle, In represents an integrated intensity within a wavenumber region of from 2,750 to 3,250 cm?1 when an intensity at a wavenumber ? within a wavenumber region of from 1,200 to 3,250 cm?1 is s normalized to 1, where a total intensity of all the toner particles is maximum at the wavenumber ?; and Iave represents an average of the In.

  • Publication number: 20210198667
    Abstract: The purpose of the present invention is to provide a molecule having a significant effect on the development of fibrosis and a substance capable of inhibiting fibrosis. This biomarker for fibrosis comprises RNA binding motif protein 7 (RBM7) and is useful as a biomarker for diagnosis of fibrosis. This fibrosis detection method comprising the step of detecting RBM7 in a biological sample from a subject preferably using an anti-RBM7 antibody is useful for diagnosis of fibrosis. This antifibrotic agent containing a substance which inhibits the expression of RBM7, preferably at least one nucleic acid drug selected from the group consisting of siRNAs, shRNAs, dsRNAs, miRNAs, and antisense nucleic acids against RBM7, is useful for treatment of fibrosis.
