Problems solved by technology

[0007] However, the above-mentioned invention needs to apply different resin layers on the surface of the substrate, so the manufacturing method is complicated.
In addition, in order to make the refractive index different, synthetic resins are mixed with inorganic fillers or metal fillers, so that the haze value (fogginess) of the transparent resin layer deteriorates, and the total light transmittance also deteriorates.

Abstract

The invention provides a base plate having a bumpy part and applied for preventing light interference patterns due to the Newton ring phenomenon and a method for manufacturing the base plate. By uniformly coating a first resin with viscosity and surface tension above prescribed values on the surface of the base plate (3), then a basal resin layer is formed. When the first resin is not hardened, a second resin (12) with viscosity and surface tension above prescribed values is provided for forming spot graphs. The basal resin layer part coated with the second resin (12) forms a sunken part or a bulging part. Then the first resin (11) and the second resin (12) are hardened. The resin layer with a smooth bumpy part formed on the surface is then formed.

Description

technical field [0001] The present invention relates to a substrate used as a sensing substrate and the like, and more particularly to a substrate having fine concavo-convex portions formed on its surface and a method of manufacturing the same. Background technique [0002] In an electronic device in which a thin air layer is formed in front of a display, if the thickness of the air layer is not uniform, light interference fringes occur, and the display quality of the display tends to deteriorate. The interference fringes of light are generated based on the so-called Newton ring phenomenon in which light reflected by one surface facing the air layer interferes with light reflected by the other surface. [0003] For example, in an electronic device in which a light-transmitting touch panel is arranged in front of a display, since an air layer is formed between two sensitive substrates constituting the touch panel, the air will be released when the touch panel is pressed with ...
