Display device

A display device comprising:

• a display part including:
• a first flat portion;
• a second flat portion spaced apart from the first flat portion in a first direction;
• a first folding portion disposed between the first flat portion and the second flat portion;
• a second folding portion disposed between the first flat portion and the first folding portion;
• and
• a third folding portion disposed between the first folding portion and the second flat portion;
• and
• a support part disposed under the display part and including a first lattice portion, a second lattice portion, a third lattice portion, a first shape holding portion and a second shape holding portion, wherein
• holes are disposed in each of the first lattice portion, the second lattice portion and the third lattice portion,
• a first boundary hole is disposed in the second lattice portion, the first boundary hole connecting the holes adjacent to the first shape holding portion,
• each of the first shape holding portion and the second shape holding portion includes no holes,
• the first shape holding portion is adjacent to the second lattice portion in a second direction intersecting the first direction,
• the second shape holding portion is adjacent to the third lattice portion in the second direction,
• the first lattice portion overlaps the first folding portion,
• the second lattice portion and the first shape holding portion overlap the second folding portion,
• the third lattice portion and the second shape holding portion overlap the third folding portion, and
• a length of the first lattice portion in the first direction is greater than a length of the second lattice portion in the first direction.
