ABSTRACT:
A display cell comprises two substrates for forming in combination a compartment, an injection hole formed in one of them, a pathway provided for connecting the compartment and the injection hole, and a concavity shaped in at least one of the two substrates. The concavity assures that the pathway has a predetermined width by the depth of the concavity in order that the pathway conducts a liquid to the compartment. Preferably, the depth of the concavity is in the order of about 10 to about 100 .mu.m.
