Patent number: 9627283Abstract: In a liquid crystal display device it is desirable to test in the state of TFT substrates, without reducing the number of TFT substrates to be obtained from one mother TFT substrate, and without increasing the overall size of the TFT substrates. Test terminals are formed on the outside of terminals for driving the liquid crystal display device. The test terminals of the specific TFT substrate are formed in another TFT substrate just below the specific TFT substrate. The area in which the test lines are formed is a space in which a sealing material is formed, between the display area and an end of the lower TFT substrate. Thus, the size of the TFT substrates is not actually increased. A test line area is not separately formed and not discarded, so that the number of TFT substrates to be obtained from one mother TFT substrate is not reduced.Type: GrantFiled: January 22, 2015Date of Patent: April 18, 2017Assignees: Japan Display Inc., Panasonic Liquid Crystal Display Co., Ltd.Inventors: Jun Gotoh, Takanori Nakayama

Patent number: 8817200Abstract: A contact resistance in a through-hole with a source or a drain electrode connected to a TFT is decreased, thereby improving the operation efficiency of a display device. In the through-hole, a source portion of the TFT is connected to a source electrode 8. The source electrode 8 is formed of three layers comprising a barrier metal, an Al alloy 82, and a cap metal 83. The barrier metal is divided into a lower layer 81a in contact with the semiconductor layer and an upper layer 81b in contact with the Al alloy. The lower layer 81a of the barrier metal is formed by sputtering, the lower layer 81a is heat-treated and, subsequently, an upper layer 81b of the base metal, the Al alloy 82, and the cap metal 83 are formed continuously by sputtering. Since the upper layer 81b of the barrier metal in contact with the Al alloy 82 is not oxidized, increase in the contact resistance in the through-hole can be prevented.Type: GrantFiled: February 16, 2011Date of Patent: August 26, 2014Assignees: Japan Display Inc., Panasonic Liquid Crystal Display Co., Ltd.Inventors: Taro Asai, Jun Gotoh, Eiji Oue, Hiroaki Asuma, Katsumi Nakayashiki, Makoto Kurita

Patent number: 8451418Abstract: A liquid crystal display device having a high definition screen in which a pixel electrode is formed in a region surrounded by a gate line and a drain line, and a trapezoidal protrusion having an upper surface and inclined surfaces is formed below the gate line. Since a TFT is formed over a trapezoidal protrusion and a channel portion is formed over the upper surface and the inclined surfaces of the trapezoidal protrusion, the width of the channel portion can be enlarged compared to that of a channel portion formed over a plane. The pixel electrode is in contact with a source electrode at the inclined surface of the trapezoidal protrusion. This configuration allows the TFT and a contact of the pixel electrode and a source electrode to be formed over part of the trapezoidal protrusion.Type: GrantFiled: October 28, 2011Date of Patent: May 28, 2013Assignees: Hitachi Displays, Ltd., Panasonic Liquid Crystal Display Co., Ltd.Inventors: Jun Gotoh, Hirotaka Imayama, Shinichi Komura, Masato Shimura
