Abstract: PROBLEM TO BE SOLVED: To provide a polarization plate adjustment method capable of obtaining a high optical transmissivity by matching the direction of the orientation of a plate with the direction of the transmitting axis of the polarization plate. SOLUTION: The manufacturing method includes a substrate position adjustment process where the direction of a liquid crystal substrate 103 is adjusted to a TFT side master polarization plate 105 whose transmitting axis Tc is known, a polarization plate position adjustment process where the direction of a color filter polarization plate 107 is adjusted to the TFT side master polarization plate 105 whose transmitting axis Tc is known, and a process where the liquid crystal substrate 103 and the color filter polarization plate 107 are adhered by almost matching the direction of an orientation axis Tb of the liquid crystal substrate 103 with the direction of the transparent axis of the color filter polarization plate 107.
