Abstract
A display device includes: a display panel including a first area, a second area including an alignment mark, and a bending area disposed between the first and second areas and bent such that the second area is disposed under the first area; a heat radiating layer disposed between the first area and the second area; a spacer disposed between the heat radiating layer and the second area; and a light-blocking tape disposed between the heat radiating layer and the spacer and extending outside an edge of the spacer when viewed on a plane. The alignment mark overlaps the light-blocking tape when viewed on the plane.
Claims20
A display device in a folded state, comprising:
- a display panel including a first area, a second area including an alignment mark, and a bending area connecting the first and second areas and bent such that the second area is disposed under the first area;
- a heat radiating layer disposed between the first area and the second area;
- a spacer disposed between the heat radiating layer and the second area;
- and
- a light-blocking tape disposed between the heat radiating layer and the spacer and extending beyond an edge of the spacer in a direction orthogonal to a thickness direction of the display device when viewed on a plane,
- wherein the alignment mark overlaps the light-blocking tape in the thickness direction when viewed on the plane,
- wherein the spacer is not disposed between the alignment mark and the light-blocking tape, and
- wherein the spacer and the alignment mark are arranged such that external light reflected by the spacer is not incident on the alignment mark.
A display device in a folded state, comprising:
- a display panel including a first area, a second area including an alignment mark, and a bending area connecting the first and second areas and bent such that the second area is disposed under the first area;
- a heat radiating layer disposed between the first area and the second area;
- a spacer disposed between the heat radiating layer and the second area;
- a light-blocking tape disposed between the heat radiating layer and the spacer, extending outside an edge of the spacer and overlapping the alignment mark when viewed on a plane;
- a printed circuit board connected to one side of the second area;
- a first tape attached to the printed circuit board and the heat radiating layer and adjacent to an edge of the printed circuit board;
- and
- a second tape attached to the printed circuit board and not attached to the heat radiating layer, the second tape being located farther away from the edge of the printed circuit board than the first tape.
An electronic device comprising:
- a display device having a first transmissive area defined therein through which an optical signal passes;
- an electro-optical module disposed under the display device and which overlaps the first transmissive area and receives the optical signal when viewed on a plane;
- and
- a case which accommodates the display device and the electro-optical module,
- wherein the display device is in a folded state and includes:
- a display panel including a first area, a second area including an alignment mark, and a bending area connecting the first and second areas and bent such that the second area is disposed under the first area;
- a heat radiating layer disposed between the first area and the second area;
- a spacer disposed between the heat radiating layer and the second area;
- and
- a light-blocking tape disposed between the heat radiating layer and the spacer and extending beyond an edge of the spacer in a direction orthogonal to a thickness direction of the display device when viewed on the plane, and
- wherein the alignment mark overlaps the light-blocking tape when viewed in the thickness direction on the plane,
- wherein the spacer is not disposed between the alignment mark and the light-blocking tape, and
- wherein the spacer and the alignment mark are arranged such that external light reflected by the spacer is not incident on the alignment mark.
