Abstract
A display panel having a pair of spaced apart flexible substrates and a display medium sandwiched therebetween. A multiple seal contains the display medium between the substrates and maintains the substrates in spaced separation. The multiple seal includes a first seal for strongly adhering to the substrates and a second seal for forming a low water permeability seal. A process for the production of a display panel having a pair of spaced apart flexible substrates and a display medium sandwiched therebetween. A first sealant which strongly adheres to the substrates is printed on the interior surface of one substrate. A second seal, which has low water permeability, is printed on the other substrate. A spacer is scattered on at least one of the substrates. The substrates are combined together and the sealants are cured to form a display panel.
