Abstract: A mechanical liquid crystal display (LCD) device and particularly to a mechanical LCD device for automatically and rapidly unloading and storing the LCD panel that is especially suitable for a LCD device which has a display panel higher than the case to allow the display panel to be folded and stored includes a case for housing an extendable deck. The case has a coupling mechanism on one side. The extendable deck has a front side pivotally coupled with a LCD panel holding mechanism. The LCD panel holding mechanism has a downward folding actuation means located thereon which is linked to the front side of the extendable deck. The structure thus formed can replace the expensive electronic circuit control to enable users to automatically and rapidly unload or retract and store the display panel, and also adjust and remember the viewing angle of the display panel to meet user's requirements.
