Display device
The present disclosure relates to a display device including: a flexible substrate including an active area and a bezel area disposed outside the active area, the active area including a module area in which multiple holes are provided; a back plate disposed on one surface of the flexible substrate, and being provided with an opening disposed in a manner that corresponds to the module area; a thin-film transistor and wire formation layer disposed on another surface of the flexible substrate, and including multiple light-transmitting areas disposed in a manner that corresponds to the opening; and a module received within the opening of the back plate, wherein the module receives light from outside through the multiple light-transmitting areas, the multiple holes, and the opening.
1. A display device comprising:
a substrate including an active area and a bezel area, the active area including a first area where a plurality of sub-pixels are arranged and a second area where pixels and multiple light-transmitting areas are arranged;
a buffer layer on the substrate;
a thin-film transistor and wire formation layer on the buffer layer;
a light-emitting element layer corresponding to the plurality of sub-pixels;
a bank corresponding to the second area;
at least one power line on the bezel area, the at least one power line providing power to the plurality of sub-pixels and including a first power line and a second power line, and
wherein the first power line is formed as a bar in a direction parallel to one side of the bezel area,
wherein the first power line is a first lower power line and the second power line is a second lower power line; and
wherein the at least one power line further includes a first upper power line and a second upper power line, and
wherein the at least one power line includes a third power line disposed along an outermost edge of the bezel area.
2. The display device of claim 1 , wherein the first power line is on at least one of one side of the bezel area adjacent to a data integrated circuit (IC) and another side opposite to the one side.
3. The display device of claim 1 , further comprising:
a gate driver including shift registers disposed on opposite sides, respectively, outside the active area.
4. The display device of claim 3 , wherein each of the shift registers receive a start pulse and at least two shift clock signals.
5. The display device of claim 4 , wherein the gate driver further includes level shifters supplying the start pulse and the at least two shift clock signals to the shift registers, respectively.
