Display device, method of manufacturing the same, and electronic device including the same

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

• forming a light-emitting element on a mother substrate comprising a cell area and a dummy area surrounding the cell area, the light-emitting element overlapping the cell area;
• forming a preliminary polarization layer overlapping the cell area and the dummy area on the light-emitting element, the preliminary polarization layer comprising a first preliminary functional layer, a preliminary polarization film, and a second preliminary functional layer which are sequentially stacked;
• irradiating a first laser along edges of the cell area toward the mother substrate to form a substrate by removing a portion of the mother substrate and a portion of the preliminary polarization layer in the dummy area;
• and
• irradiating a second laser along a first edge of the substrate having a curved shape to form a polarization film having a recessed side surface by deforming the preliminary polarization film in the first edge of the substrate in a plan view and form a first functional layer and a second function layer covering the recessed side surface by deforming the first preliminary functional layer and the second preliminary functional layer in the first edge of the substrate in the plan view.

An electronic device comprising:

• a display device comprising a light-emitting element;
• and
• a power supply configured to provide power to the display device,
• wherein the display device comprises:
• a substrate having an edge comprising a first side extending in a first direction, a second side extending in a second direction intersecting the first direction, and a curved portion which connects the first side and the second side and has a predetermined curvature in a plan view;
• the light-emitting element disposed on the substrate;
• and
• a polarization layer disposed on the light-emitting element and comprising:
• a polarization film disposed on the light-emitting element and having a side surface which is recessed from a side surface of the polarization layer in the curved portion in the plan view;
• a first functional layer disposed between the light-emitting element and the polarization film and covering the recessed side surface of the polarization film in the curved portion in the plan view;
• and
• a second functional layer disposed on the polarization film, covering the recessed side surface of the polarization film, and contacting the first functional layer in the curved portion in the plan view.
