Display panel and manufacturing method thereof

An organic light-emitting diode display, comprising:

• an active array layer;
• an organic light-emitting display layer disposed on the active array layer, wherein the organic light-emitting display layer comprises red light-emitting units, green light-emitting units, and blue light-emitting units, and a top surface and a bottom surface of the red light-emitting units, the green light-emitting units, and the blue light-emitting units of the organic light-emitting display layer are both continuously connected and planar;
• a first inorganic layer disposed on the organic light-emitting display layer;
• a light filter layer disposed on the first inorganic layer, wherein the light filter layer comprises a plurality of light filter units configured to increase light extraction efficiency of the light filter layer, the light filter units comprise first light filter units, second light filter units, and third light filter units;
• the first light filter units are aligned with the red light-emitting units, the second light filter units are aligned with the green light-emitting units, and the third light filter units are aligned with the blue light-emitting units;
• the first light filter units are made of red ink, the second light filter units are made of green ink, and the third light filter units are made of blue ink, the light filter units are spaced from each other and each of the light filter units is hemispherical, and each of the light filter units is covered by an arc structure that is shaped to conform with the light filter units;
• a first organic layer disposed on the light filter layer;
• and
• a second inorganic layer disposed on the first organic layer.
