摘要： A display device includes a first substrate including a display area and a non-display area around the display area; a pad portion at an end part of the first substrate in the non-display area; a power voltage transmitting line electrically connected to the pad portion and surrounding at least part of the display area; a second substrate facing the first substrate; and a sealant between the first substrate and the second substrate and surrounding the display area. In the end part, the power voltage transmitting line includes a first portion overlapping the sealant and extending in a first direction and a second portion not overlapping the sealant, and the second portion includes a first protrusion protruded from the first portion in a second direction crossing the first direction, and a second protrusion protruded in a direction opposite to the second direction.
