  • Patent number: 10620345
    Abstract: Provided is an antireflection film obtained by laminating, in succession, a transparent substrate, a first layer, and a second layer having a lower refractive index than the refractive index of the first layer. The first layer is obtained by curing a film containing an ionizing radiation-curable material, a quaternary ammonium salt material, a leveling agent, and a solvent, and has a structure wherein a middle layer, hard coating layer and recoating layer are laminated in succession from the transparent substrate side. The recoating layer does not contain a quaternary ammonium salt. The hard coating layer contains a quaternary ammonium salt, and the concentration of the quaternary ammonium salt in the hard coating layer gradually increases from the middle layer side to the recoating layer side.

  • Patent number: 8564514
    Abstract: In a liquid crystal display device that uses a liquid crystal material having spontaneous polarization and is actively driven by a TFT, a voltage corresponding to image data is applied twice by driving the TFT of each pixel electrode on a line by line basis of a liquid crystal panel, during writing in one frame. During erasure in one frame, voltage application to liquid crystal by batch selection of all the pixel electrodes is performed three times. With this three times of voltage application, it is possible to achieve a black display state in each pixel and make the stored charge amount at the liquid crystal in each pixel substantially zero.

  • Patent number: 8466861
    Abstract: A liquid crystal display device displays an image by stacking a plurality of liquid crystal panels, and by controlling a light transmittance with voltage application to liquid crystal of each panel, wherein during execution of voltage application to the liquid crystal of one of the panels, a voltage to the liquid crystal of the other panel serves as a non-display voltage. No image is displayed simultaneously on the two or more stacked liquid crystal panels. In the liquid crystal panel to which no voltage is applied and on which no image is displayed, the longitudinal axial direction of liquid crystal molecules coincides with the polarizing axial direction of polarizers, or is orthogonal to the polarizing axial direction; therefore, no influence is exerted on the overall double refraction, and the overall voltage-transmitted light intensity characteristic corresponds to the sum of the voltage-transmitted light intensity characteristics of the respective panels.
