Abstract
A fan-out circuit including a plurality of fan-out wires is provided, where the fan-out wires are not electrically connected to each other. Each of the fan-out wires includes a first detouring portion, an extending portion, and a second detouring portion. The first detouring portion has a chip bonding terminal and a first connecting terminal. A pitch of any two adjacent chip bonding terminals is P1. The second detouring portion has a second connecting terminal and a signal-line connecting terminal. The second connecting terminal is connected with the first connecting terminal through the extending portion. A pitch of any two adjacent signal-line connecting terminals is P2, and P2>P1. Among the fan-out wires, a part of the first detouring portions has a ladder shaped pattern.
