  • Patent number: 9107274
    Abstract: Provided is a color display element which employs a conventional system of monochrome electronic paper without degrading the degree of brightness and with ease and lower costs. Also provided is a method of producing a color display element including a pair of opposing substrates having electrodes, charged display bodies of white color and black color which are enclosed between the opposing substrates, and a color filter which is disposed on one of the opposing substrates, the method including forming a color filter disposed on a viewing side by forming, first, colored regions of at least three colors of blue, green, and red by an inkjet method on a transparent support substrate, and forming remaining regions other than the colored regions so as to be colorless or transparent.
    Type: Grant

  • Patent number: 9097822
    Abstract: Provided are a lenticular lens sheet which can be used in a stereoscopic display, a rear projection display, a projection screen, and the like, and means for manufacturing the lenticular lens sheet at low cost without using any mold. The lenticular lens sheet includes at least a transparent support substrate; a plurality of lenticular lenses; and a partition between adjacent ones of the plurality of lenticular lenses, and the lenticular lens sheet is obtained by applying a transparent resin composition ink by an inkjet method to an area partitioned by the partition and subsequently curing the transparent resin composition ink with ultraviolet rays.
