In the present embodiment, the area of the display layer 70 is smaller than the area of the second transparent substrate 20, the area of the first transparent substrate 10 is substantially the same as the area of the second transparent substrate 20, and the display layer 70 occupies a partial area of the entire mirror display device, as shown in fig. 2, in the present embodiment, a light absorbing layer 80 is further included, and the light absorbing layer 80 is located on the side of the second transparent substrate 20 away from the first transparent substrate 10 and covers the area outside the display layer 70.
In this embodiment, it is preferable that a touch layer 90 is further included, and the touch layer 90 is located between the display layer 70 and the second transparent substrate 20.
In this embodiment, the first transparent substrate 10 and the second transparent substrate 20 may include, but are not limited to, a chemically or physically strengthened tempered or semi-tempered transparent glass, a rigid or flexible high temperature resistant polymer material (e.g., PMMA, PC, ABS, MS, etc.), and other substrate materials with a light transmittance meeting the requirement may also be used, and the light transmittance may reach 85%, 90%, 95% or more. The thickness of the first transparent substrate 10 and the second transparent substrate 20 is between 1.0 and 5.0 millimeters.

The specular polarizing layer 30 may be selected from, for example, an APF film, an RPM film, a DBEF film, a wire mesh reflective polarizing film, or the like.
In this embodiment, the display layer 70 is preferably a TFT-LCD display screen, as shown in fig. 4, the polarization direction of the polarized display light emitted from the TFT-LCD display screen is consistent with the transmission axis direction of the specular polarization layer, so that the polarized display light emitted from the display layer 70 can penetrate through the specular polarization layer 30 by nearly 100%, thereby reducing light loss, improving the light utilization rate of the display, and improving the display contrast.
