Display device enabling external objects to be shown therein

A display device enabling external objects to be shown therein, comprising:

• a main body formed with a space;
• a backlight module disposed in the space and comprising a light projection surface;
• and
• a display module disposed in the space, and disposed separately from the backlight module by a spacing, a length of the spacing being sufficient for at least one external object to be located therein, and the display module comprising a transparent display structure, a first optical film disposed on one side of the transparent display structure facing the light projection surface, and a second optical film disposed on one side of the transparent display structure distant from the light projection surface,
• wherein the first optical film is provided with a polarization function and comprises a first polarization axis;
• the first optical film is disposed for a light directly projected by the backlight module with a polarization direction same as the first polarization axis and a light reflected by the main body with a polarization direction same as the first polarization axis passing through;
• and the first optical film is disposed for reflecting a light directly projected by the backlight module with a polarization direction different from the first polarization axis and a light reflected by the main body with a polarization direction different from the first polarization axis, and wherein the second optical film is disposed for a light from the transparent display structure passing through, and the second optical film reflects an ambient light outside the main body.
