Zusammenfassung:	Provided is a polarizing plate that is used in a liquid crystal shutter of a photofabrication apparatus, said polarizing plate including an absorption-type polarizer in which a dichroic dye is oriented, the absorption-type polarizer having a maximum absorption wavelength in the wavelength range of 370-470 nm, and the polarizing plate having a weighted parallel transmittance Xp380-440 of not less than 20% and a weighted orthogonal transmittance Xc380-440 of 0.0001-0.1%. L'invention concerne une plaque de polarisation qui est utilisée dans un obturateur à cristaux liquides d'un appareil de photofabrication, ladite plaque de polarisation comprenant un polariseur de type à absorption dans lequel un colorant dichroïque est orienté, le polariseur de type à absorption ayant une longueur d'onde d'absorption maximale dans la plage de longueurs d'onde de 370 à 470 nm, et la plaque de polarisation ayant une transmittance parallèle pondérée Xp380-440 supérieure ou égale à 20% et une transmittance orthogonale pondérée Xc380-440 de 0,0001 à 0,1%. 光造形装置の液晶シャッターに用いる偏光板であって、　前記偏光板は、二色性色素が配向した吸収型偏光子を含み、前記吸収型偏光子は、波長３７０～４７０ｎｍの範囲に極大吸収波長を有し、　前記偏光板は重加平行透過率Ｘｐ３８０－４４０が２０％以上であり、且つ、重加直交透過率Ｘｃ３８０－４４０が０．０００１～０．１％である、　偏光板。
