Abstract: The present invention provides a curvature-adjustable backplane and a liquid crystal display device having the backplane. The curvature-adjustable backplane includes a bottom plate (1). The bottom plate (1) is made of a material of thermal bimetal. The bottom plate (1) includes a plurality of openings (11) formed therein to extend in a lengthwise direction or a widthwise direction thereof, whereby the plurality of openings (11) helps increase a localized length-to-width ratio (L1/W1) of the bottom plate (1) so that when the curvature-adjustable backplane undergoes curving deformation, the extent of curving thereof in a lengthwise direction of the openings is far greater than the extent of curving thereof in a widthwise direction of the openings to realize precise adjustment of the curvature of the backplane and help release the stress of the backplane resulting from deformation and thus making the deformation of the backplane easy.
