Patent number: 9304362Abstract: In a liquid crystal display device including: TFT substrate; color filter; counter electrode; interlayer insulation film; pixel electrode; alignment film; liquid crystal layer; counter substrate; and Si semiconductor layer. The color filter, counter electrode, interlayer insulation film, pixel electrode, and alignment film being formed on the side where the TFT substrate is provided, the counter substrate being disposed in facing relation to the TFT substrate with the liquid crystal layer put between the counter substrate and TFT substrate, the Si semiconductor layer is formed between the pixel electrode and interlayer insulation film. Even when light from a backlight is absorbed by the color filter and sufficient light cannot reach the alignment film, electric charges accumulated on the alignment film can escape to the pixel electrode in an early stage by the Si semiconductor layer formed under the alignment film, thereby capable of erasing the afterimage in an early stage.Type: GrantFiled: August 12, 2013Date of Patent: April 5, 2016Assignee: Japan Display Inc.Inventors: Chikae Matsui, Masanao Yamamoto, Noboru Kunimatsu, Hidehiro Sonoda

Patent number: 9035310Abstract: The invention prevents disconnection of data lines that traverse two-layered gate lines via an insulating film. Data lines 20 override and thereby traverse gate lines 10 with an insulating film deposited therebetween. The gate lines 10 each have a two-layered structure including a lower AlCu layer 11 and an upper MoCr layer 12. When the thickness ratio of the upper layer 12 to the lower layer 11 is in the range of 0.4 to 1.0, it is possible to prevent a decrease in the etch speed of the upper layer 12 near the side edges of the gate line 10, which occurs due to galvanization. As a result, the upper layer 12 is prevented from having an overhang. The absence of overhangs on the gate lines 10 prevents the data lines 20 from being disconnected at the intersections of the gate lines 10 and the data lines 20.Type: GrantFiled: October 2, 2012Date of Patent: May 19, 2015Assignee: JAPAN DISPLAY INC.Inventors: Yoshinori Ishii, Daisuke Sonoda, Masanao Yamamoto

Patent number: 8928847Abstract: The liquid crystal display device includes a pixel structure provided with a large wall formed along a long side of a pixel with a rectangular plane, a small wall formed at a center of the pixel and extending in the same direction as the large wall, a wall electrode formed on a wall surface of the large wall, a plane electrode formed between the small and large walls, in which the wall electrode and the plane electrode form a pixel electrode, and a common electrode formed on a surface of the small wall. The large wall has a part with an increased thickness at an end part of the pixel. The wall electrode is bent toward the center of the pixel. This structure prevents decrease of reverse twist of liquid crystal at an end part of the pixel as well as generation of domain, thus improving transmittance of the screen.Type: GrantFiled: March 8, 2013Date of Patent: January 6, 2015Assignee: Japan Display Inc.Inventors: Takato Hiratsuka, Osamu Itou, Masanao Yamamoto, Daisuke Sonoda
