eqnarray is implemented as
\begin{array}{lcr}
\displaystyle <stuff> & \textstyle <relation> & \displaystyle <stuff>
...
The first fraction is in the \textstyle field thus causing it to be
typeset in a much smaller size.
Anyway, this was just to explain what was going on. The optimum solution
is to use amsmath as Herb pointed out.
