Patent number: 10551686Abstract: In a liquid crystal display device including a TFT substrate and a counter substrate, when an organic passivation film is not formed in the TFT substrate, the distance between the TFT substrate and the counter substrate in the display area of a liquid crystal display panel is provided by a cylindrical spacer. Also, the distance in the area where pixels, scan lines, and image signal lines are not formed within the liquid crystal display panel is provided by the cylindrical spacer. In this case, it is necessary to form a mount. The layer structure of the mount is the same as that of the TFT substrate with which the cylindrical spacer in the display area comes into contact. This makes it possible to equalize the distance of the liquid crystal layer of the liquid crystal display panel without an increase in production cost, and to prevent uneven brightness or color.Type: GrantFiled: December 19, 2018Date of Patent: February 4, 2020Assignee: Japan Display Inc.Inventor: Takahiro Nagami

Patent number: 10539834Abstract: A display substrate, a method for manufacturing the same and a display device are provided. The display substrate includes: a base substrate; and an alignment layer and multiple supporting spacers, which are on the base substrate. The alignment layer is formed by performing rubbing alignment on an alignment film formed on the base substrate by using a rubbing cloth. A distance between adjacent ones of the multiple supporting spacers in a rubbing alignment direction of the alignment film, and a length of a contact between a fiber of the rubbing cloth and the alignment film during the rubbing alignment meet a first preset condition, so that a number of supporting spacers that are passed through by the fiber of the rubbing cloth during each contact between the fiber and the alignment film is less than or equal to a first threshold value.Type: GrantFiled: April 14, 2016Date of Patent: January 21, 2020Assignees: BOE TECHNOLOGY GROUP CO., LTD., BEIJING BOE OPTOELECTRONICS TECHNOLOGY CO., LTD.Inventors: Hongpeng Li, Jian Li, Yuguang Fan

Patent number: 10486268Abstract: A first substrate, bonded to a second substrate by a material, is provided. The first substrate is transparent to at least some wavelengths of electromagnetic radiation. The first substrate is irradiated with the electromagnetic radiation to which the first substrate is transparent, such that the electromagnetic radiation impinges on the material causing a decomposition thereof at a location at an interface between the first substrate and the material. The decomposition results in, at the location, an interface of the first substrate and an atmosphere of the decomposition. The atmosphere of the decomposition has an optical property resulting in ceasing the decomposition of the material.Type: GrantFiled: February 18, 2017Date of Patent: November 26, 2019Assignee: International Business Machines CorporationInventors: Fuad E.
