Display device with signal lines on different layers connected over bending area

A display device comprising:

• a base layer including a first portion, a second portion extending from the first portion, and a third portion extending from the second portion;
• light emitting elements including a first light emitting element, a second light emitting element, and a third light emitting element, the light emitting elements disposed on the first portion;
• a first front signal line disposed on the first portion and electrically connected to the first light emitting element;
• a second front signal line disposed on the first portion and electrically connected to the second light emitting element, wherein the first front signal line and the second front signal line are disposed on different layers;
• a third front signal line electrically connected to the third light emitting element, wherein the first front signal line, the second front signal line, and the third front signal line are disposed on different layers;
• a first rear signal line disposed on the third portion, wherein the first rear signal line and the first front signal line are disposed on a same layer;
• a second rear signal line disposed on the third portion, wherein the second rear signal line and the second front signal line are disposed on a same layer;
• a third rear signal line disposed on the third portion, wherein the third rear signal line and the third front signal line are disposed on a same layer;
• connection lines that overlap the second portion, wherein at least one of the connection lines electrically connects the first front signal line and the third rear signal line;
• a first insulating layer covering the first front signal line and the first rear signal line, the first insulating layer disposed under the second front signal line and the second rear signal line;
• a second insulating layer covering the second front signal line and the second rear signal line, the second insulating layer disposed under the third front signal line and the third rear signal line;
• and
• a third insulating layer covering the third front signal line and the third rear signal line, the third insulating layer disposed under the connection lines.
