3-D image display system and display equipment and shutter glasses thereof

A 3D image display system, comprising:

• a display equipment, comprising an LCD module, wherein the LCD module has a linear polarizing unit and is capable of generating an image light from the linear polarizing unit;
• and
• a shutter glasses, comprising two liquid crystal optical units, at least one linear polarizing unit, and at least one polarizing optical element, wherein the linear polarizing unit is disposed between the polarizing optical element and the liquid crystal optical units, the image light passes through the polarizing optical element, the linear polarizing unit, and one of the liquid crystal optical units in sequence, and when the image light passes through one of the liquid crystal optical units, the other liquid crystal optical unit blocks the image light,
• wherein the display equipment further comprises another polarizing optical element disposed on a transmission path of the image light and used for converting a polarization state of the image light from a linear polarization into a non-linear polarization.
