  • 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: 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.
