  • Patent number: 8736803
    Abstract: A mother TFT substrate having plural TFT substrates, and a mother counter substrate having plural counter substrates are bonded together to form a mother panel. At this time, the interior of the mother panel is sealed only with a sealing material, without forming a sealant separately in seal portions. The mother counter substrate has plural counter substrates of liquid crystal cells. A sealing material is arranged in two rows surrounding the counter substrates in the periphery of the mother counter substrate, except for the seal portions in which seal portion sealing materials are arranged in two rows in a staggered manner on the short sides. When the mother counter substrate and the mother TFT substrate are overlapped and the inside air is let out, the sealing materials are heated. Then, the seal portion sealing materials are bridged together to seal the interior of the mother panel.

  • Patent number: 8537298
    Abstract: In a liquid crystal display device of IPS mode with a smaller number of layers, a gate electrode is formed on a TFT substrate. A gate insulating film is formed to cover the gate electrode, on which a semiconductor layer is formed. A drain electrode and a source electrode are placed on the semiconductor layer. A planar pixel electrode is formed from ITO on the gate insulating film prior to the formation of the drain electrode, source electrode, image signal line, and the like. This process is performed to prevent the image signal line, the drain electrode, the source electrode, and the like, from being consumed by the cell reaction through a developer during the patterning of the ITO when a pin hole is present in the ITO, in order not to cause disconnection. As a result, it is possible to improve the production yield and achieve high reliability.
