Patent number: 10095067Abstract: There is achieved a liquid crystal display device having a smaller picture frame region and a seal part of improved reliability. A liquid crystal display device includes a TFT substrate having a display region and a terminal region and formed with an organic passivation film, a counter substrate attached to the TFT substrate through a seal part, and a liquid crystal contained inside the seal part. A hole is formed at a predetermined pitch on the organic passivation film of the TFT substrate corresponding to the seal part when viewed on a plane. When the hole is viewed on a plane, a shortest distance from the hole to the hole is four micrometers or greater and 12 micrometers or less at a height of h1=0.9×h2 from a bottom face of the hole, where a depth of the hole is defined as h2.Type: GrantFiled: December 3, 2015Date of Patent: October 9, 2018Assignee: Japan Display Inc.Inventors: Tomonori Nishino, Masato Shimura, Tomokazu Ishikawa, Yuki Kuramoto, Satoshi Hashimoto

Patent number: 10048552Abstract: This invention envisages flexible wiring substrate terminals serving to connect with the wires for preventing dielectric breakdown caused by static electricity during the manufacturing process, and reducing the number of the flexible wiring substrate terminals. On a mother TFT substrate, signal lines extend over each liquid crystal cell in a manner flanking a scribe line between the adjacent liquid crystal cells. The signal lines of each liquid crystal cell are connected with connecting lines striding the scribe line. This reduces the number of static electricity countermeasure wires extending from the flexible wiring substrate terminals of each liquid crystal cell. Once completed, the individual liquid crystal cells are separated from one another, with no adverse effects caused by the connecting lines.Type: GrantFiled: August 11, 2016Date of Patent: August 14, 2018Assignee: Japan Display Inc.Inventors: Tomonori Nishino, Syou Yanagisawa, Kentaro Agata, Hiroyuki Abe, Takayuki Suzuki
