Abstract: A reflectance-adjustable reflector including a phase modulation element and a first polarizer is provided. The phase modulation element includes a first substrate, a second substrate opposite to the first substrate, a phase modulation layer located between the first substrate and the second substrate, a first electrode layer located between the first substrate and the phase modulation layer, and a second electrode layer located between the second substrate and the phase modulation layer. Thicknesses of the first substrate and the second substrate are between 0.01 mm and 0.5 mm. The first polarizer is disposed on the first substrate. The first substrate is located between the first polarizer and the first electrode layer. A total thickness of the phase modulation element and the first polarizer is less than 1 mm. A reflectance-adjustable display device is also provided.
