Abstract: A projection film and a projection device are provided. The projection film includes a pattern layer, a first light-transmission layer, a second light-transmission layer and a plurality of light-transmission particles. The pattern layer includes a light-transmission portion and a non-light-transmission portion. The first light-transmission layer is disposed below the pattern layer. The second light-transmission layer is disposed below the first light-transmission layer. The light-transmission particles are disposed between the first light-transmission layer and the second light-transmission layer. The impurity generated by the light-transmission particles will be reduced by utilizing a second light-transmission layer having a refractive index close to the refractive index of the light-transmission particles.

Abstract: A projector including a light source, a light valve, a projection lens and a displacement module is provided. The light source generates an illumination light. The light valve converts the illumination light into a multi-pixel area image light. The projection lens is disposed in a transmission path of the multi-pixel area image light. The image displacement module includes a carrier, an optical element, a frame and a base. The carrier, the frame and the base are substantially coplanar with each other, and the multi-pixel area image light provided is configured to be moved by the optical element and being moved along a third direction in response to the spinning of the carrier, and the first direction is different from the second direction. Furthermore, a three-dimensional printing apparatus is also provided.
