  • Publication number: 20130107184
    Abstract: According to one embodiment, a display includes a first substrate including a scan line, a signal line crossing the scan line, a pixel electrode including first electrodes extending in a direction in which the signal line extends and arranged side by side in the direction in which the scan line extends, a common electrode including second electrodes extending in the direction in which the signal line extends between the first electrodes and arranged with a predetermined space to the first electrodes, and a shielding portion arranged at least between the signal line and the first electrodes arranged near the signal line and to which a same voltage as that of the common electrode is applied, second substrate arranged opposite to the first substrate, and a liquid crystal layer.

  • Publication number: 20120327352
    Abstract: According to one embodiment, a liquid crystal display apparatus includes a first substrate including a pixel electrode including comb-like projections extending in a first direction and arranged in a second direction substantially perpendicular to the first direction, a common electrode including comb-like projections extending in the first direction between the comb-like projections of the pixel electrode and arranged with a predetermined spacing from the comb-like projections of the pixel electrode, a second substrate arranged opposite to the first substrate, and a liquid crystal layer sandwiched between the first substrate and the second substrate. A space width between the comb-like projection of the pixel electrode and the comb-like projection of the common electrode of end portion in the second direction is greater than a space width between the comb-like projection of the pixel electrode and the comb-like projection of the common electrode in a center portion.

  • Patent number: 7612857
    Abstract: A liquid crystal display device is provided which allows an ultraviolet curing sealant to be cured without blockage of ultraviolet rays by wiring formed of a conductive metal film and which ensures stabilized quality of reliability with the occurrence of defective image display inhibited. The liquid crystal display device is manufactured through a process including: bonding a liquid crystal driving substrate provided with wiring formed of a conductive metal film to its counter substrate; injecting a liquid crystal material into a clearance defined between the substrates through a liquid crystal material injecting portion; and then sealing the injecting portion with an ultraviolet curing sealant, the wiring being positioned so as not to overlap the interface between the liquid crystal material and the ultraviolet curing sealant in plan view.

  • Publication number: 20070229738
    Abstract: A liquid crystal display panel includes an array substrate, a counter-substrate, a liquid crystal layer which is held between the array substrate and the counter-substrate and contains liquid crystal molecules whose alignment state is to be transitioned to a bend alignment for enabling a display operation, a retardation plate which is disposed at least on the counter-substrate, and a polarizer which is disposed on the retardation plate. The array substrate and counter-substrate include a pair of electrodes which are covered with alignment films, respectively, and are opposed to each other to define a rectangular display area, and the polarizer has an absorption axis which is substantially parallel or substantially perpendicular to each of the sides of the display area.
