A tap tape of a tape carrier package prevents connection parts from being
eroded. The tap tape includes a base film having a device hole formed to
mount a driver chip for driving a panel of a flat panel display, input
patterns positioned on the base film and having a plurality of electrode
pads connected to a side of the device hole, output patterns positioned
on the base film and having a plurality of electrode pads connected to
the other side of the device hole; and connection parts positioned at the
ends of the input patterns or the output patterns and having electrode
pads of widths different from widths of the electrode pads.
