Abstract
A liquid crystal panel includes a first substrate on which pixel electrodes are formed in a matrix pattern, a second substrate on which a counter electrode is formed, an ultraviolet reducing layer formed on one of the first and second substrates and corresponding to the matrix pattern of the pixel electrodes, and a polymer dispersion liquid crystal layer sandwiched between the first and second substrates. The polymer dispersion liquid crystal layer is cured by irradiating ultraviolet light from the side on which the ultraviolet reducing layer is formed such that the polymer dispersion liquid crystal layer arranged between the counter electrode and each pixel electrode has an average liquid crystal drop diameter which is larger than that arranged in other areas.
