Patent ID: 11935904
Assignee: LG DISPLAY CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC H

Claim 19:
20. A display device, comprising:
a substrate;
a subpixel on the substrate;
a data line connected to the subpixel, the data line extending along a first direction in a plan view of the display device;
a reference voltage line supplying a reference voltage to the subpixel, the reference voltage line extending along the first direction;
a first voltage line connection pattern located over the substrate, the first voltage line connection pattern comprising a material having a first resistance and including a portion that extends along a second direction and intersects the reference voltage line in the plan view of the display device; and
a second voltage line connection pattern including a portion that extends along the second direction and intersects the reference voltage line and overlaps the portion of the first voltage line connection pattern that extends along the second direction in the plan view of the display device, the second voltage line connection pattern comprising a material having a second resistance that is less than the first resistance, disposed in an area excluding a part area where the portion of the second voltage line connection pattern that overlaps the portion of the first voltage line connection pattern, and electrically connected to the first voltage line connection pattern,
wherein, the first voltage line connection pattern electrically connects the subpixel in the display device and the reference voltage line for supplying the reference voltage to the subpixel.
