Abstract
The backplane for a liquid crystal display (LCD) device includes side walls, and the backplane at least includes two backplane units. A horizontal moving guide device is arranged between the adjacent backplane units, and an elastic device which enables the two backplane units to relatively elastically expand and contract horizontally is further arranged between the adjacent backplane units. The backplane of the LCD device of the present disclosure is designed to be able to elastically expand and contract in a direction perpendicular to a light emitting diode (LED) lightbar. When a light guide panel (LGP) in the backplane expands after absorbing heat, the backplane is extended by a pushing force, and heat expansion quantity of the LGP is directly absorbed. When the LGP is contracted because of temperature drop, the backplane is shortened under action of the elastic device, and a light coupling distance between the LGP and the LED lightbar is always kept constant.
