Patent number: 7405781Abstract: A substrate for use in a liquid crystal display, including an insulating substrate cooperating with an oppositely arranged opposite substrate to hold a liquid crystal. A plurality of pixel regions are arranged on the insulating substrate in a matrix form, in each of which a switching element is formed. At least one resin color filter layer is formed on the pixel regions to cover the switching element. Additionally, at least one layer of the resin color filter layers of the plural colors has a cruciform-shaped pattern protruding to cover the switching elements of neighboring pixels when viewed in a direction of a normal of a substrate surface.Type: GrantFiled: February 9, 2006Date of Patent: July 29, 2008Assignee: Sharp Kabushiki KaishaInventors: Atuyuki Hoshino, Shiro Hirota, Naoto Kondo, Tetsuya Fujikawa, Masahiro Kihara, Katsunori Misaki, Seiji Doi, Tomoshige Oda, Akira Komorita, Akihiro Matsui, Manabu Sawasaki, Masahiro Ikeda, Takashi Takagi, Tomonori Tanose, Takuya Saguchi, Hidetoshi Sukenori, Hiroyasu Inoue
