  • Display device including common power supply line
    Patent number: 11588002
    Abstract: A display device may include a first substrate, a second substrate, a plurality of display elements, a sealing unit, and a common power supply line. The second substrate may overlap the first substrate. The display elements may be positioned between the first substrate and the second substrate. The sealing unit may surround the display elements in a plan view of the display device and may be arranged between the first substrate and the second substrate. The common power supply line may at least partially surround the display elements in the plan view of the display device and may include a protrusion. The protrusion may protrude beyond the sealing unit and may be positioned between the sealing unit and a first edge of the first substrate in the plan view of the display device.
    Type: Grant
