Display panel with a substrate having curved surfaces

A display panel, comprising:

• a base substrate that includes a front surface and a rear surface, wherein each of the front surface and rear surface is parallel to a plane defined by a first direction and a second direction wherein the second direction crosses the first direction;
• a light emitting element layer disposed on the front surface of the base substrate;
• and
• an encapsulation layer that covers the light emitting element layer,
• wherein an edge of the base substrate includes:
• a first straight portion that extends in the first direction and a second straight portion that extends in the second direction, wherein each of the first straight portion and the second straight portion extends in a straight line;
• and
• a curved-shaped portion that connects the first straight portion and the second straight portion, wherein the curved shaped portion includes at least one curved-surface-shaped portion that has a curved shape, wherein the at least one curved-surface-shaped portion includes:
• a first curved-line surface formed in art edge of the front surface of the base substrate, wherein the first curved-line surface connects the front surface to a flat side surface of the base substrate;
• and
• a second curved-line surface formed in an edge of the rear surface of the base substrate, wherein the second curved-line surface connects the flat side surface to the rear surface of the base substrate.
