Abstract
An OLED display panel, a manufacturing method thereof and a display apparatus are provided. The display panel includes a substrate, a light emitting structure layer and a viewing angle improving layer which are arranged on the substrate. The light emitting structure layer is configured to emit light to the viewing angle improving layer. The viewing angle improving layer is disposed on one side of the light emitting structure layer away from the substrate and is configured to adjust the viewing angle of the display panel to allow the viewing angle of the display panel along a first direction to satisfy a first viewing angle range, and allow the viewing angle along a second direction to satisfy a second viewing angle range. The first direction is perpendicular to the second direction.
