Display device
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.
1. A display device comprising:
a first substrate comprising 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 not overlapping the pad portion; and
a sealant between the first substrate and the second substrate and surrounding the display area,
wherein, in the end part, the power voltage transmitting line comprises a first portion overlapping the sealant and extending in a first direction, and a second portion not overlapping the sealant,
the second portion comprises 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, and
the first protrusion and the second protrusion each extend in the first direction, and the first protrusion and the second protrusion each have a length in the first direction that is larger than a width in the second direction.
2. The display device of claim 1 , wherein the first protrusion and the second protrusion comprise a part that does not overlap the pad portion in the second direction.
3. The display device of claim 2 , wherein the power voltage transmitting line further comprises a third part extending from the end part in the second direction and connected to at least one pad of the pad portion.
4. The display device of claim 1 , wherein at least one of the first protrusion and the second protrusion comprises a part of which a width varies along the first direction.
5. The display device of claim 4 , wherein the second protrusion comprises a part of which a width decreases along the first direction and then increases.
6. The display device of claim 1 , wherein the first portion has a non-uniform thickness, and the second portion has a uniform thickness.
7. The display device of claim 1 , further comprising a light emitting element disposed in the display area, and
the power voltage transmitting line is a common voltage transmitting line that is electrically connected to a common electrode of the light emitting element.
8. The display device of claim 7 , further comprising a transistor in the display area and connected to a pixel electrode of the light emitting element, and
the common voltage transmitting line is arranged as a same layer as source and drain electrodes of the transistor.
9. The display device of claim 7 , further comprising a transistor in the display area and connected to a pixel electrode of the light emitting element, and
the common voltage transmitting line is arranged as a same layer as a gate electrode of the transistor.
