Patent number: 10409114Abstract: Color irregularity caused by color mixture in peripheral parts of the screen is avoided when a liquid crystal display device is used in a curved state. The liquid crystal display device includes a liquid crystal display panel in which a liquid crystal is sandwiched between a counter substrate and a TFT substrate having pixels formed thereon like a matrix, the TFT substrate and the counter substrate are bonded to each other with a seal member, an upper polarizing plate is arranged on the counter substrate, and a lower polarizing plate is arranged under the TFT substrate. In the liquid crystal display device, the liquid crystal display panel is curved along a curvature axis and width wsa of the seal member on each side orthogonal to the curvature axis is greater than width wsb of the seal member on each side parallel to the curvature axis.Type: GrantFiled: September 26, 2016Date of Patent: September 10, 2019Assignee: Japan Display Inc.Inventors: Yohei Iwai, Ryosuke Imaseki

Patent number: 9818771Abstract: A display device made of a TFT substrate and a driver IC is configured to eliminate bad connection between them. On the driver IC connected to the TFT substrate, a first principal surface has first bumps formed along a first side having a first edge and second bumps formed along a second side opposite to the first side and having a second edge. The TFT substrate has first terminals and second terminals connected to the first and the second bumps, respectively. On a cross section taken perpendicularly to the first and the second sides, the first principal surface has a first area between the first and the second bumps and a second area between the second bumps and the second edge. The first and the second areas are bent toward the TFT substrate.Type: GrantFiled: January 23, 2017Date of Patent: November 14, 2017Assignee: Japan Display Inc.Inventors: Yohei Iwai, Ryosuke Imaseki

Patent number: 7167227Abstract: A liquid crystal device comprises a pair of substrates 2a and 2b, liquid crystal L held between the substrates 2a and 2b, and an IC 13 mounted on an overhang section 2c of the substrate 2a. A terminal column 26a comprises a plurality of terminals 18 aligned in a direction away from the liquid crystal L. The terminal column 26a has, in the order of the closeness to the liquid crystal L, a first noneffective terminal region within a distance “A” from a first side of the IC, an effective terminal region X continuing from the first noneffective terminal region, and a second noneffective terminal region within a distance “B” from a second side of the IC, the second noneffective terminal region continuing from the effective terminal region. The distances A and B are adjusted to satisfy the relationship A>B.Type: GrantFiled: May 5, 2005Date of Patent: January 23, 2007Assignee: Seiko Epson CorporationInventors: Yasuhito Aruga, Ryosuke Imaseki
