  • Patent number: 8395733
    Abstract: A method of manufacturing a liquid crystal display includes: forming a protective film on at least either of first and second mother substrates disposed opposite to each other and each having panel regions; removing the protective film in a region which is associated with at least start and end points of a seal material and which is near the periphery of an area including the panel regions, applying the seal material to the protective film on the first and second mother substrates in the vicinity of dividing lines at which the mother substrates are divided into individual panel regions using a dispenser, the seal material being applied from the start to end points to form a gap to serve as a liquid crystal injection port; combining the first and second mother substrates; and dividing the combined first and second mother substrates into the individual panel regions.

  • Patent number: 8077281
    Abstract: A liquid crystal device includes a liquid crystal layer between a pair of substrates. One substrate includes pixel electrodes, an insulating layer and a common electrode having a plurality of slits. An electric field between the pixel and common electrodes turns liquid crystal molecules in a predetermined direction in regions corresponding to the slits. Each slit includes a first straight portion extending from a center of the pixel electrode toward both sides of the pixel electrode and second straight portions extending from the ends of the first straight portion to the outside of the pixel electrode. The first and second portions each form an acute angle with an initial orientation of the liquid crystal molecules in a direction opposite to the predetermined direction. The acute angle between the second portions and the initial orientation is larger than the acute angle between the first portion and the initial orientation.

  • Patent number: 8064013
    Abstract: A liquid crystal display panel 10 of the present invention includes an array substrate 11 with a display region in which a pixel electrode is formed in each of the regions enclosed by a plurality of signal lines and scan lines deployed as matrices, a opposed substrate 12 with a common electrode 31, a sealing agent 35 sealing a peripheral portion of the array substrate 11 and the opposed substrate 12, a liquid crystal layer sealed between both substrates, a border region 34 including a reflector 37 and a transparent electrode 38 is formed on an interlayer 23 at a periphery of the display region of the array substrate 11, and at least a part of an outer peripheral side is lacking from the common electrode 31 at a position corresponding to the border region 34. Thanks to such structure, the border region improves the appearance at the periphery of the display region, and the phenomenon of night vision alongside the scan line wiring does not occur.

  • Patent number: 7978291
    Abstract: In the liquid crystal display device of the present invention, channels 13 containing gaps 12 of the adjacent color filers CF are formed on the surface of a transparent thickness section 11, such that when orientation agent is applied by means of a roller to the surface of the transparent section wall 11, the surplus orientation agent is conducted to either side of the transparent thickness wall 11 through the channels 13, such that the orientation agent does not gather and is dissolved, and the orientation thickness film does not become uneven as to produce any orientation defect and defective display is thereby avoided.

  • Patent number: 7738060
    Abstract: Liquid crystal display panel 10 is provided with TFT and pixel electrode 19, between which interlayer insulator 17 is interposed, and with reflective section 15, in each of a matrix of pixels; having first substrate whereon the pixel electrode 19 and the TFT's electrode D electrically connect via contact hole 20 formed in the reflective section 15; second substrate whereon at least one protrusions 311 to 313 are formed on common electrode in positions corresponding to the each pixel; perpendicular alignment layers deposited on each substrate; and liquid crystal 29 with negative dielectric anisotropy disposed between substrates. In position corresponding to base of protrusion 313 provided opposite the second substrate's contact hole 20, light-blocking film 363 is formed so as to cover the base viewed from above. Thus, liquid crystal display panel is provided wherein light leakage from reflective section's contact hole and from protrusions is curbed, with high contrast and display quality.

  • Patent number: 7557878
    Abstract: A liquid crystal display panel 10 of the invention has: an array substrate with a display region 14 in which a pixel electrode is formed in each of the regions enclosed by a plurality of signal lines and scan lines deployed as matrices; a opposed substrate with a common electrode; and a liquid crystal layer that is sealed between the array substrate and the opposed substrate by means of sealing agent 35 that seals together the peripheries of the two substrates. Features are: the periphery of the array substrate's display region 14 is covered by a border region 34 that has a reflector 37a and a continuous transparent electrode 38a, the outer periphery of the border region 34 is sealed by the sealing agent 35, and the border region 34's transparent electrode 38a is electrically coupled to the common electrode. Thanks to such structure, the border region improves the appearance at the periphery of the display region, and the phenomenon of night vision alongside the scan line wiring does not occur.
