In this embodiment, a side of the first functional layer 10 opposite to the second functional layer 20 is a light exit side LS, and a side of the second functional layer 20 opposite to the first functional layer 10 is a light entrance side RS. In other words, the first functional layer 10 is directed towards the viewer and the second functional layer 20 is directed away from the viewer towards the projection device.

When the projection light emitted from the projection apparatus enters the second functional layer 20, the projection light is reflected by the reflective surface 211 of the second microstructure 21 and is reflected in the horizontal direction toward the first functional layer 10, and the reflected light passes through the first light-transmitting portion 12 of the first functional layer 10 and enters the visual range of the viewer, so that the viewer can view the projection picture. As shown in fig. 14, when the ambient light on the light exit side LS enters the first functional layer 10, the ambient light is absorbed by the first microstructures 11, and thus cannot enter human eyes as the projection light, so that the interference of ambient light such as sunlight and light to the projection can be greatly reduced, the display effect of the projection picture can be improved, and the contrast and brightness of the picture can be improved. The projection light is reflected by the second microstructures 21, which can realize parallel light, reduce the loss of the projection light and is also beneficial to improving the brightness of the projection picture.
