Composite film, manufacturing method thereof, display module and display device

The embodiment of the invention provides a composite film, a manufacturing method thereof, a display module and a display device. The composite film comprises an electromagnetic shielding layer, a buffer layer and an anti-reflection layer located between the electromagnetic shielding layer and the buffer layer, wherein the electromagnetic shielding layer and the buffer layer are arranged in a stacked mode. By arranging the anti-reflection layer between the electromagnetic shielding layer and the buffer layer of the composite film, the reflection of incident light by the electromagnetic shielding layer is reduced, so that the problem of an arc angle bright edge of a display module applying the composite film is solved, and the user experience is improved. 本申请实施例提供了一种复合膜及其制作方法、显示模组和显示装置。复合膜包括层叠设置的电磁屏蔽层和缓冲层，以及位于电磁屏蔽层和缓冲层之间的抗反射层。通过在复合膜的电磁屏蔽层和缓冲层之间设置抗反射层，减少电磁屏蔽层对入射光的反射，从而解决应用复合膜的显示模组弧角亮边的问题，改善用户体验。
