Abstract: A display panel includes a display region and a peripheral region other than the display region. The display panel includes, in the peripheral region, a gate drive circuit and a first trunk line extending in a column direction. The first trunk line includes a first edge on a first side corresponding to the display region side in the row direction and a second edge on a second side corresponding to a side opposite to the display region in the row direction. The first trunk line includes a first portion and a second portion, each including the first edge and the second edge, and the first edge of the second portion is closer to the second side in the row direction than the first edge of the first portion. The first portion is not provided with an element, and the second portion includes a region provided with an element.
