Abstract
Provided are a low reflection structure, a display panel, a display device, and a manufacturing method of a display panel. Related is the field of display technologies. The low reflection structure includes a first lens array, a second lens array, and a light blocking layer located between the first lens array and the second lens array. The first lens array includes multiple first convex lenses. The second lens array includes multiple second convex lenses. The light blocking layer includes a light blocking part and multiple light transmitting parts. The light blocking part at least partially surrounds the multiple light transmitting parts. An image focal plane of the first convex lens and an object focal plane of the second convex lens are within a same plane. A focus of each first convex lens of the multiple first convex lenses is located within a light transmitting part of the multiple light transmitting parts.
