Component for an information display device

A component fior an information display device, said component comprising:

• a transparent substrate having a surface;
• said surface having a first refractive index;
• said surface selectively coated in a pattern comprising a transparent conductive layer disposed at least at a first region of said surface and at a second region of said surface;
• wherein said first region of said surface is separated from said second region of said surface by a third region of said surface devoid of said transparent conductive layer;
• said transparent conductive layer having a second refractive index higher than said first refractive index;
• said first, second and third regions commonly evenly overcoated with a transparent layer comprising nanopartides, said transparent layer disposed over said transparent conductive layer at said first and second regions and also disposed over said third region devoid of said transparent conductive layer;
• wherein said transparent layer is substantially the same in refractive index to said transparent conductive layer having said second refractive index;
• and
• wherein said transparent layer comprises nanopartides with a size ranging from 10 nm to 100 nm.
