Also a multilayer substrate is provided in which light reflectance is reduced even when the substrate has a plurality of layers that differ in refractive index from each other. In the display device of one embodiment, the reflectance of light reflected by the internal structure, of light incident on the internal structure through a display screen, is less than 1.0%. The multilayer substrate of one embodiment includes a first layer and a second layer disposed adjacently to the first layer. The refractive index of the second layer varies continuously from an interface where the second layer is adjacent to the first layer in a direction from the first layer, with the variation being started at a value of the refractive index at the interface where the first layer is adjacent to the second layer.Type: GrantFiled: May 26, 2010Date of Patent: December 23, 2014Assignee: Sharp Kabushiki KaishaInventors: Nobuaki Yamada, Kazuyoshi Sakuragi, Akiyoshi Fujii, Tokio Taguchi
