DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF

A display device includes a substrate having first and second surfaces, transistors, data lines, and light-emitting diodes above the first surface, front data pads above the first surface, electrically connected to the data lines, and arranged in a first direction along a first side of the substrate, a first insulating layer above the front data pads, rear data pads under the second surface, and arranged in the first direction, a second insulating layer under the rear data pads, and defining first and second openings overlapping one of the rear data pads, a first virtual line extending from the first opening in the first direction not overlapping the second opening, and a side wire connecting a front data pad to a rear data pad, and electrically connected to and overlapping the first rear data pad through the first opening.
