  • Patent number: 7821608
    Abstract: Disclosed herein is a liquid crystal display device which can control a viewing angle in up/down and left/right directions without need of forming white subpixels. In the liquid crystal display device which includes a first region having liquid crystal molecules aligned in a slanted direction, and a second region having the liquid crystal molecules aligned in up and down directions or in left and right directions. Voltage is independently applied to the second region from the first region.

  • Publication number: 20040239867
    Abstract: A method for manufacturing a liquid crystal display is disclosed. The liquid crystal display includes a liquid crystal material between opposing first and second substrates, spacers for maintaining a cell gap and a plurality of first and second color filters. The method includes the steps of: (a) estimating an optimum quantity of the liquid crystal material by measuring the height of the spacers, the thickness difference between the first color filters and the second color filters, and the distance between two adjacent color filters; (b) applying an adhesive onto the periphery of the first substrate or the second substrate; (c) dispensing the liquid crystal material to the first substrate, wherein the quantity of the dispensed liquid crystals is controlled based on the estimated optimum quantity; (d) superposing the second substrate upon the first substrate; and (e) curing the adhesive to obtain the liquid crystal display.
