Patent number: 8395747Abstract: A method for repairing a glass substrate is a method for repairing a glass substrate (10) having a depression (60) formed in a display region (5). Into the depression (60), plural types of starting material from which a cross-linked epoxy resin or a cross-linked (meth)acrylic resin is made are put together with a photoinitiator, and the starting materials thus put are copolymerized by light irradiation and heat treatment. In the result, the depression (60) in a surface of the glass substrate (10) is repaired by a transparent resin (65) obtained through the copolymerization of the plural types of starting material. Therefore, the glass substrate (10) can be repaired at a low temperature without performing a sintering process.Type: GrantFiled: June 3, 2008Date of Patent: March 12, 2013Assignees: Sharp Kabushiki Kaisha, Kyoritsu Chemical & Co., Ltd.Inventors: Takenori Yoshizawa, Masaya Ueda, Yoshitomo Denpo

Publication number: 20120147314Abstract: The display device (100) of this invention has pixels (P) arranged in columns and rows to form a matrix pattern. Each pixel (P) is defined by subpixels (R, G, B, Y) arranged in m columns and n rows (where n and m are integers and n and m?2) to form a matrix pattern and that include first, second, third and fourth subpixels (R, B, Y, G) representing first, second, third and fourth colors, respectively. In three arbitrary pixels (P) arranged in line in one of row and column directions, if the central one of the three is called a first pixel (P1) and the other two second and third pixels (P2, P3), the arrangement of the subpixels (R, G, B, Y) in the first pixel (P1) is different from that of the subpixels (R, G, B, Y) in the second and third pixels (P2, P3). The first subpixels (R) of the first and second pixels (P1, P2) are adjacent to each other, so are their second subpixels (B). The third subpixels (Y) of the first and third pixels (P1, P3) are adjacent to each other, so are their fourth subpixels (G).Type: ApplicationFiled: August 19, 2010Publication date: June 14, 2012Applicant: SHARP KABUSHIKI KAISHAInventors: Takenori Yoshizawa, Keiichi Tanaka
