Classification: CPC H  G | IPC H

Claim 0:
1. A display device, comprising:
a plurality of subpixels disposed in a display panel;
a plurality of data lines connected to the plurality of subpixels, the plurality of data lines extending along a first direction in a plan view of the display device;
a plurality of reference voltage lines supplying a reference voltage to the plurality of subpixels, the plurality of reference voltage lines extending along the first direction; and
a plurality of reference voltage line connection patterns extending along a second direction that is different from the first direction in the plan view of the display device, each of the plurality of reference voltage line connection patterns is electrically connected to a corresponding reference voltage line of the plurality of reference voltage lines, and is electrically connected to a corresponding thin film transistor disposed in a corresponding subpixel among the plurality of subpixels,
wherein each of the plurality of reference voltage line connection patterns comprises:
a first reference voltage line connection pattern connected to the corresponding thin film transistor, the first reference voltage line connection pattern including a portion that extends along the second direction and intersects the corresponding reference voltage line of the plurality of reference voltage lines; and
a second reference voltage line connection pattern disposed on a layer different from a layer where the first reference voltage line connection pattern is disposed, and electrically connected to the first reference voltage line connection pattern, the second reference voltage line connection pattern including a portion that extends along the second direction and intersects the corresponding reference voltage lines,
wherein in the plan view of the display device, the portion of the second reference voltage line connection pattern that extends along the second direction overlaps the portion of the first reference voltage line connection pattern that extends along the second direction.
