摘要： A display panel includes a circuit substrate, multiple light-emitting components located on a side of the circuit substrate, and multiple microlenses. Each light-emitting component includes a first surface facing away from the circuit substrate and also includes a second surface at least partially surrounds the first surface. One of the first surface or the second surface is a hydrophilic surface, and the other is a hydrophobic surface. The multiple microlenses are located on a side of the multiple light-emitting components facing away from the circuit substrate. The orthographic projection of the microlens on the plane where the circuit substrate is located overlaps the orthographic projection of the first surface on the plane where the circuit substrate is located and does not overlap the orthographic projection of the second surface on the plane where the circuit substrate is located.
