A display panel includes a plurality of pads, a plurality of first contacts connected to the pads, a plurality of second contacts provided so as to be opposed to the plurality of first contacts, a polysilicon layer configured to form a plurality of polysilicon films to connect the plurality of first contacts and second contacts, and a gate metal layer. The gate metal layer forms at least one gate metal. The gate metal layer traverses the plurality of polysilicon films so as to form a plurality of transistors. The plurality of transistors are arranged in a zigzag pattern for each transistor set. A width of a portion of each of the polysilicon films, the portion forming a corresponding one of the transistors, is larger than a width of another portion of the polysilicon films. The other portion is connected to a corresponding one of the first contacts and second contacts.
