Embodiments of the present invention provide a liquid crystal display device and a producing method thereof, and relate to the field of liquid crystal display. The liquid crystal display device of the present invention comprises a liquid crystal panel and a first optical compensation structure and a second optical compensation structure located at two sides of the liquid crystal panel, and the second optical compensation structure comprises: a polarizing film layer, a compensation film layer and a biaxial film layer, wherein, the polarizing film layer is located between the compensation film layer and the biaxial film layer; and the biaxial film layer is located between the polarizing film layer and the liquid crystal panel. Through providing the biaxial film layer in the second optical compensation structure, the present invention can effectively correct the color shift generated in the diagonal direction of the liquid crystal panel and improve the product quality.
