Abstract: A transflective optical plate including a polarization conversion unit, an optical film, and a transparent protective layer is provided. The polarization conversion unit is adapted to change a polarization state of a polarized image light and includes a combiner. The optical film is disposed on the combiner. The transparent protective layer is disposed on the optical film, and the optical film is located between the combiner and the transparent protective layer. A display system is also provided.

Abstract: A composite film including a first polarizing film, at least one second polarizing film, and at least one first phase compensation film is provided. The first polarizing film has a first transmission axis. Each second polarizing film has a second transmission axis parallel to the first transmission axis. The at least one first phase compensation film is disposed between the first polarizing film and the at least one second polarizing film. Each first phase compensation film has a first optical axis. An orthographic projection of the first optical axis on the first polarizing film is parallel to an axial direction of the first transmission axis, and a first included angle between the first optical axis and the first polarizing film is greater than 0 degrees and less than 90 degrees. A display device is also provided.
