Abstract: The present invention relates to a display panel, a printing device, and a method of manufacturing the display panel. In the present invention, the width of the first conductor and the second conductor can be increased by matching the printing device with the display panel, and the risk of the open circuit between the first conductor and the first bonding terminal and the open circuit between the second conductor and the second bonding terminal is reduced. The first conductor and the second conductor of the present invention are not on the same plane, so that the risk of short circuit between the first conductor and the second conductor can be reduced.
