Abstract
A display panel, a manufacturing method thereof and a display apparatus are provided. The display panel is divided into a display region and at least one light transmission region at least partially surrounded by the display region, including a base substrate; a driving circuit layer; an anode layer; a first insulating layer over the anode layer and including a first insulating sub-layer in the display region and a second insulating sub-layer in the at least one light transmission region; a functional film layer in the at least one light transmission region, the functional film layer has a first thickness so that a height difference between a height of a surface of the first insulating sub-layer and a height of a surface of the second insulating sub-layer is less than a first threshold; and an encapsulation leveling layer arranged on surfaces of the first and second insulating sub-layer.
