A backplate of a display device has a first rigid region, a second rigid region spaced apart from the first rigid region, and a flexible region between the first rigid region and the second rigid region. The flexible region includes an electromagnet and encloses a magneto-rheological fluid that suspends magnetic particles. The rigidity of the flexible region changes responsive to changes in magnetic field generated by the electromagnet.

Disclosed is a broadband reflection type brightness enhancement polarizer, which includes a cholesteric liquid crystal film laminate having a broadband selective reflecting wavelength range in which a plurality of cholesteric liquid crystal films having selective reflecting wavelength ranges different from each other by having different mixture ratios of a curable nematic liquid crystal compound expressed by the chemical formula 1 and a curable chiral compound expressed by the chemical formula 2 are laminated; and a film having &#xbc;&#x3bb; phase difference laminated on one surface of the cholesteric liquid crystal film laminate. This polarizer has wide selective reflecting wavelength ranges of the cholesteric liquid crystal films composing the polarizer, so the entire visible ray range can be covered just by laminating several cholesteric liquid crystal films. Accordingly, the polarizer may be manufactured relatively thinner, so the brightness can be greatly improved when the polarizer is applied to a liquid crystal display.
