Abstract
A display having first and second substrates positioned in a juxtaposed relationship to one another. The first and second substrates have a spherical configuration including conforming inner concave and convex surfaces of the first and second substrates, respectfully, and an outer concave surface of the second substrates. Electrically activated display elements are formed on the conforming inner concave and convex surfaces of the first and second substrates so that images produced by the display elements can be viewed from the concave surface of the second substrate. The first and second substrates are connected to one another with a peripheral vacuum seal sealing the display elements between the first and second substrates. The concave viewing surface eliminates the effects of glare.
