Abstract

A display device includes a display module and a module support part disposed on one surface of the display module, where the module support part may include a support layer disposed on one surface of the display module, a support disposed in the support layer and having greater rigidity than the support layer, and a magnetic particle layer disposed above or under the support in the support layer. A method of manufacturing a module support part may include preparing a support, providing a suspension including a plurality of magnetic particles to the support, aligning the plurality of particles by applying a magnetic field to the suspension provided to the support, and forming a support layer by curing the suspension.

Claims (40)
