The invention belongs to the field of display, and discloses a liquid crystal display device and a manufacturing method of the liquid crystal display device. The liquid crystal display device comprises a liquid crystal layer, a color film layer, a polaroid and a reflecting layer, wherein the color film layer and the polaroid are arranged at one side of the liquid crystal layer, the reflecting layer is arranged at the other side of the liquid crystal layer, the color film layer comprises a plurality of pixels consisting of red, green and blue sub pixels, the display device also comprises a compensation module, the compensation module comprises compensation units corresponding to the sub pixels, and the compensation units are used for adjusting the phase difference offset of light rays of the corresponding sub pixels when the light rays of the corresponding sub pixels pass through the compensation units so that the phase differences of the light rays passing through the corresponding sub pixels in a normally black mode and/or a normally white mode are in a preset threshold value range. The liquid crystal display device has the advantages that the phase difference offset of the light rays of the corresponding sub pixels when the light rays of the corresponding sub pixels pass through the compensation units is adjusted through the arrangement of the compensation units, the effect of adjusting the phase difference offset of each sub pixel is achieved, and the goal of reducing the display color difference through matching the phase differences of each sub pixel is achieved.
