The invention discloses a liquid crystal display convenient for dust prevention. The liquid crystal display comprises a base, a reel, dustproof cloth and a spring; a supporting column is fixed to thetop of the base; a displayer is fixed to the side, away from the base, of the supporting column; hooks are fixed to the vertical faces of the two sides, close to the bottom, of the displayer; a dustproof frame is installed on the vertical face of the side, away from the hooks, of the displayer; installing frames are fixed to the two sides of the top of the dustproof frame, and the installing frames are fixedly connected with the displayer through fixing rods. The dustproof liquid crystal display is provided with dustproof cloth and hooks; a hanging rod is pulled to drive the dustproof cloth tomove out of a dustproof cloth groove; the inner side of the dustproof cloth is fixedly connected with the reel, so the dustproof cloth drives the reel to rotate when moving, and the reel drives the clockwork spring to roll; after the hanging rod enters the hook, a clockwork spring recovers deformation to generate elastic force, so the reel tightens the dustproof cloth, the hanging rod is fixed inthe hook, the dustproof cloth covers the display, and dust prevention of the display is facilitated.
