Abstract: Provided is a liquid crystal display device that includes: pixels, a pixel control unit, and a common voltage generation unit. The pixel includes: a display element; a first switching unit configured to sample each frame data; a first holding unit configured to form an SRAM, and to hold sub-frame data sampled; a second switching unit configured to output the sub-frame data; and a second holding unit configured to form a DRAM, and configured of which stored content is rewritten by the sub-frame data. The pixel control unit is configured to repeat writing the sub-frame data into the first holding units, and to operate to rewrite the stored content in the second holding units. The common voltage generation unit is configured to change a voltage value of a common voltage from a first voltage value to a second voltage value determined based on at least the one frame period.

Abstract: There is provided a method for producing an elongated-shaped silica sol comprising the following steps: (a) adding an aqueous solution containing a water soluble Ca salt and/or Mg salt to an aqueous colloidal solution of active silicic acid with an SiO2 concentration of 1 to 6% by mass and a pH of 2 to 5 in a mass ratio of CaO and/or MgO to SiO2 in the active silicic acid of 1500 to 15,000 ppm, and mixing; (b) adding alkali metal hydroxide, a water soluble organic base, or water soluble silicate thereof to an aqueous solution obtained through (a) in a determined molar ratio to SiO2, and mixing; (c) heating a mixture obtained through (b) at 85 to 200° C. for 0.5 to 20 hours so as to obtain a colloidal solution; (d) removing, from the colloidal solution obtained through (c), part of water and at least part of anions derived from the aqueous solution containing the water soluble Ca salt and/or Mg salt; and (e) heating a colloidal solution obtained through (d) at a temperature of 80 to 195° C.
