DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE

原文（中国語）

An optical path regulation layer is located on the side of an encapsulation layer of the display panel away from a driving backplane. The optical path regulation layer includes a first refractive unit and a second refractive unit. The refractive index of the second refractive unit is greater than the refractive index of the first refractive unit. The orthographic projection of the first refractive unit or the second refractive unit on the driving backplane covers the orthographic projection of at least one sub-pixel on a base substrate. After an exit light of the sub-pixel passes through an interface between the side surface of the first refractive unit and the side surface of the second refractive unit, the exit angle of the exit light is increased or decreased.
