  • Publication number: 20160062512
    Abstract: A manufacturing process of an electrode substrate includes a step of forming a protective layer so as to cover a conductor pattern by applying raw material liquid discharged as droplets to an upper surface of a substrate in a first region and a second region of the upper surface of the substrate. At this time, an application amount of the raw material liquid per unit area in the second region is made smaller than an application amount of the raw material liquid per unit area in the first region, so that an average film thickness of the protective layer of a portion formed in the second region is made smaller than an average film thickness of the protective layer of a portion formed in the first region.

  • Publication number: 20160054608
    Abstract: A first electrode 30 for the touch panel is formed on an outer side of a counter substrate 200, and the protection film 210 is formed over the first electrode 30 to cover it. A defect 211 in the protection film 210 is filled in with another protection film 210 by inkjet coating. The surface of the protection film 210 is rubbed to a rough surface finish. The polarization plate 220 is attached to the rough surface of the protection film 210 via an adhesive material 221. Since the defective region is repaired by the formation of the protection film 210, corrosion of the first electrode (wiring) 30 due to the presence of the adhesive material 221 can be prevented, and since the surface of the second protection film 210 is made rough, a resulting increase in adhering surface area enhances the adhesion for attaching the polarization plate 220.

  • Patent number: 9213196
    Abstract: A display includes: a reflective or semi-transmissive display panel; a light-scattering layer disposed on a top surface of the display panel; and an auxiliary light source. The light-scattering layer is an anisotropic front scattering layer which relatively strongly scatters light incident from a specific direction within a first angle range and a second angle range. The light-scattering layer has a first scattering central axis and a second scattering central axis. The first angle range and a third angle range overlap each other in an angle sub-range not including a first specific angle and an incident-plane symmetrical angle symmetrical to a second specific angle. The auxiliary light source allows light therefrom incident from a side closer to the auxiliary light source or from a side closer to the display panel to mainly enter the light-scattering layer within the second angle range.
