Liquid crystal display device

A method of producing a liquid crystal display device, comprising the steps of:

• providing a scattering liquid crystal panel including a scattering-type liquid crystal layer which is capable of taking a transparent state and a scattering state, the scattering liquid crystal panel having a front face and a rear face;
• providing a retroreflection plate;
• and
• combining the retroreflection plate with the scattering liquid crystal panel so that the retroreflection plate retroreflects at least a portion of light which enters through the front face of the scattering liquid crystal panel and travels toward the rear face, the method further comprising a step of:
• before the retroreflection plate is combined with the scattering liquid crystal panel, determining whether the scattering liquid crystal panel satisfies the relationship of 0.45≦log(I0-10/I20-30)≦1.48, where, regarding light which enters through the rear face of the scattering liquid crystal panel and goes out through the front face when the scattering-type liquid crystal layer is in the scattering state, I0-10 represents a mean value of scattering intensity of light which goes out at an angle in a range from 0 degrees to 10 degrees with respect to a normal direction of the front face, and I20-30 represents a mean value of scattering intensity of light which goes out in a range from 20 degrees to 30 degrees.
