Abstract: PROBLEM TO BE SOLVED: To restrain the fluctuation of average transmissivity even when the temperature of a liquid crystal display panel is fluctuated by adjusting the thickness of a liquid crystal layer so that the retardation value of the liquid crystal layer in the partial area of each picture element may be a specified value.
