Abstract: A liquid crystal display includes a casing, a frame mounted in the casing, a support mounted in the frame, a motor, and a tray. The casing includes a front plate for holding a display screen and a rear cover attached to the front plate. The rear cover includes a lower casing portion having a side opening. The support mounted is slidable through the side opening so as to be located between an extended position out of the casing and a retracted position in the casing. The support includes a receiving space for receiving a backlight and a drive circuit for the backlight. The motor moves the support to the extended position or the retracted position. The tray is removably received in the receiving space of the support and includes a portion for receiving an X-ray film.
