The invention discloses a liquid crystal display device. The liquid crystal display device comprises an array substrate, a color film substrate opposite to the array substrate and a liquid crystal layer sandwiched between the array substrate and the color film substrate, wherein the array substrate comprises a first transparent base as well as first electrodes and second electrodes formed on the first transparent base, the first electrodes and the second electrodes are arranged on different layers, and an insulation layer is arranged therebetween; the color film substrate comprises a second transparent base as well as black matrixs formed on the second transparent base, third electrodes, a photoresist layer and optical clearance objects; the third electrodes cover the black matrix and the surface on which the black matrix is not arranged, of the transparent base, the photoresist layer covers the third electrodes, the optical clearance objects cover the photoresist layer, and the optical clearance objects comprise a plane layer covered with the photoresist layer and optical clearances integrally extending from the plane layer and used for providing interval support for the liquid crystal layer; liquid crystal molecules in the liquid crystal layer are negative.
