A display device includes a display panel with a folding area between two non-folding areas. A window is on the display panel. A first adhesive layer is between the window and the display panel, and has a first thickness. A lower structure is under the display panel. The lower structure includes a first support layer overlapping the first non-folding area and the second-non-folding area, a digitizer under the first support layer, including a loop coil, and overlapping the first non-folding area and the second non-folding area, an electromagnetic shielding layer under the digitizer having a second thickness, a metal layer under the electromagnetic shielding layer, and an insulating second support layer under the metal layer. The first thickness is about 75 μm to about 100 μm, and the second thickness is about 30 μm to about 60 μm.

Foldable display device and electronic device including the same

A display device includes a display panel including a first area, a bending area, and a second area, and comprising a plurality of pixels disposed in the first area, a driving chip disposed on an upper surface of the second area of the display panel and electrically connected to the plurality of pixels, a support layer disposed on a lower surface of the first area of the display panel, and a spacer disposed on the lower surface of the first area and overlapping the support layer in a plan view, wherein the spacer comprises an upper layer, a lower layer, and a base layer having a thermal conductivity greater than a thermal conductivity of the upper layer and a thermal conductivity of the lower layer, and in case that the bending area of the display panel is folded, the spacer overlaps the driving chip in a plan view.

A display device includes a display panel including a first non-folding region, a second non-folding region, and a folding region between the first and second non-folding regions, and a lower member below the display panel. The lower member includes a support layer below the display panel and including a first support part which overlaps the first non-folding region, a second support part which overlaps the second non-folding region, and a folding part which overlaps the folding region, where openings are defined in the folding part, a digitizer below the support layer and corresponding to the first and support parts, a cover layer between the support layer and the digitizer and attached below the folding part, and a lower adhesion layer between the support layer and the digitizer. The lower adhesion layer is between the first and second support parts.

Display device and electronic device including the same

A display device includes a window, a display module on a rear surface of the window, and including a folding area, and a non-folding area adjacent to the folding area, and a protective cover on a rear surface of the display module, and including a cover portion configured to cover the folding area and the non-folding area of the display module, and holding portions extending in a first direction, or in a second direction crossing the first direction, from the cover portion, and protruding outside the display module when viewed in a plane.

An electronic device includes a display panel including a first panel area, a bending area, and a second panel area, a support layer disposed under the first panel area of the display panel, a set bracket disposed under the support layer, a first waterproofing tape disposed between the support layer and the set bracket, the first waterproofing tape being attached to the set bracket, and a second waterproofing tape attached to the set bracket. The bending area may be bendable, the second panel area may be disposed under the first panel area, the first waterproofing tape may be spaced from the second panel area in a thickness direction of the display panel, and the second waterproofing tape may overlap the second panel area.

Electronic device
