It is intended to facilitate optimization of the configuration and distribution density of columnar spacers for realizing a liquid crystal display device having reduced low-temperature voids, lower bulging, and pressure-induced unevenness. A method of producing a substrate for a liquid crystal display device includes the steps of: providing a sample substrate; forming a columnar spacing structure sample on the sample substrate, the columnar spacing structure having at least one resin layer; determining a spring modulus k0(mN/mum) of the columnar spacing structure sample and a cross-sectional area Sps0 of a smallest portion of the columnar spacing structure sample, and calculating a spring modulus Kps(=k0/Sps0) of the columnar spacing structure sample per unit area; and with respect to an area S of a display region of the liquid crystal display device, a cross-sectional area Sps of a smallest portion of a columnar spacing structure to be formed on the substrate for the liquid crystal display device, and a number n of columnar spacing structures in the display region, prescribing the number n of columnar spacing structures and the cross-sectional area Sps of the smallest portion so that a spring modulus Kpt per unit area of display region, defined as Kpsx(Spsxn/S), is within a range of no less than 0.00008 mN/mum3 and no more than 0.00237 mN/mum3.
