Flexible display device and method of manufacturing the same

A method of manufacturing a display device, the method comprising:

• forming a temporary layer on a sacrificial substrate;
• forming a support layer over the temporary layer;
• forming a buffer layer, a shielding layer, and a bottom insulating layer above the support layer;
• forming a cell array defining a plurality of pixel regions and comprising a ground line connected to a ground voltage source of an external circuit on one of the buffer layer and the bottom insulating layer;
• forming a light emitting array comprising a plurality of light emitting structures, the location of the plurality of light emitting structures corresponding to the location of the plurality of pixel regions on the cell array;
• forming a sealing layer on the cell array to seal the light emitting array;
• separating the sacrificial substrate from the support layer using an interface between the temporary layer and the support layer;
• adhering an insulating substrate to the support layer;
• and
• connecting the external circuit to the cell array,
• wherein the plurality of light emitting structures emit light toward the sealing layer, and
• wherein the ground line is connected to the shielding layer through a contact hole to partially expose the shielding layer.

A display device comprising:

• a cell array comprising a plurality of driving switch devices, each of the driving switch devices including a semiconductor layer, a source electrode, a drain electrode, and a gate electrode;
• a light emitting array comprising a plurality of light emitting structures to emit light upward from the cell array, each of the light emitting structures being formed on the drain electrode of each the driving switch devices, respectively;
• at least one insulating layer formed under the cell array;
• a ground line extending through a contact hole in the cell array and the at least one insulating layer;
• and
• a shielding layer formed directly under the at least one insulating layer so that the top and sides of the shielding layer are covered by the at least one insulating layer, the shielding layer being formed of a reflective metallic material to reflect light emitted from the light emitting array,
• wherein the ground line is connected to the shielding layer through the contact hole partially exposing the shielding layer.
