| description | The utility model provides an optical structure layer and a curtain, relates to the technical field of projection imaging equipment parts, and solves the technical problem that an optical structure layer on a curtain in the prior art cannot ensure a larger visual angle under the condition of higher gain. The optical structure layer comprises a substrate layer, a structure part, a metal reflection layer and an anti-oxidation layer, the structure part is of a protruding structure and is arranged on the substrate layer, the metal reflection layer is arranged on the substrate layer and the structure part, and the anti-oxidation layer is arranged on the metal reflection layer. The projection screen is used in projection imaging, the metal reflecting layer is adopted to ensure the gain of the screen, then multi-angle light reflection is realized through the protruding structure part, finally, a large visual angle is ensured under the condition that the gain is ensured, and the metal reflecting layer has polarizatio |
