Display panel including a filling layer

A display panel comprising:

• a substrate including a first area, a second area at least partially surrounding the first area, and a third area at least partially surrounding the second area;
• an insulation layer disposed on the substrate in the second area, and defining a first groove, wherein the first groove is spaced apart from the first area;
• a first partition disposed on the insulation layer in the second area, and spaced apart from the first groove;
• a filling layer disposed on the substrate in the first area and the second area and at least partially overlapping the first groove;
• and
• a light emitting diode layer disposed on the substrate in the third area and adjacent to the first partition.

A display panel comprising:

• a substrate including a first area, a second area at least partially surrounding the first area, and a third area at least partially surrounding the second area;
• an insulation layer disposed on the substrate in the second area;
• a first partition disposed on the insulation layer in the second area, and spaced apart from the first area;
• a first spacer disposed on the substrate in the first area;
• a second spacer disposed on the insulation layer in the second area;
• a filling layer disposed on the substrate in the first area and the second area and at least partially overlapping each of the first spacer and the second spacer;
• a light emitting diode layer disposed in the third area on the substrate and adjacent to the first partition;
• and
• an encapsulation layer disposed on the filling layer, the first partition, and the light emitting diode layer.

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

• forming a substrate including a first area, a second area at least partially surrounding the first area, and a third area at least partially surrounding the second area;
• forming a barrier insulation layer on the substrate in the second area;
• forming a dam structure on the barrier insulation layer in the second area;
• forming a partition on the barrier insulation layer in the second area, spaced apart from the dam structure to form a gap therebetween;
• etching the partition to form a concave-convex structure, the structure including convex portions protruding from the second area to the first area, and further including concave portions disposed between adjacent convex portions;
• forming an encapsulation layer on the partition;
• and
• forming a filling layer between the substrate and the encapsulation layer in the first area, and in the gap between the barrier insulation layer, the dam structure, the partition, and the encapsulation layer in the second area.
