(EN) POLARIZING PLATE, POLARIZING PLATE ROLL, AND METHOD FOR MANUFACTURING POLARIZING FILM
(ZH) 偏振片、偏振片卷、及偏振膜的制造方法
要約
(EN) Provided is a polarizing plate which has excellent optical characteristics and in which fluctuation of optical characteristics is suppressed. This polarizing plate has a polarizing film having a thickness of 8 mum or less, a unit transmittance of 44.5% or greater, and a degree of polarization of 99.0% or greater, and a protective layer disposed on at least one side of the polarizing film, the difference between the maximum value and the minimum value of the unit transmittance in a 50 cm<2> region of the polarizing plate being 0.2% or less. Another polarizing plate according to the present invention has a polarizing film having a thickness of 8 mum or less, a unit transmittance of 44.5% or greater, and a degree of polarization of 99.0% or greater, and a protective layer disposed on at leastone side of the polarizing film, the width of the polarizing plate being 1000 mm or greater, and the difference between the maximum value and the minimum value of the unit transmittance at a positionalong the width direction of the polarizing plate being 0.3% or less.
(ZH) 本发明提供具有优异的光学特性、且光学特性的偏差得到抑制的偏振片。本发明的偏振片具有偏振膜、和配置于该偏振膜的至少一侧的保护层,上述偏振膜的厚度为8μm以下、单体透射率为44.5%以上、偏振度为99.0%以上,上述偏振片在50cm2区域内的单体透射率的最大值与最小值之差为0.2%以下。本发明的另一偏振片具有偏振膜、和配置于该偏振膜的至少一侧的保护层,上述偏振膜的厚度为8μm以下、单体透射率为44.5%以上、偏振度为99.0%以上,该偏振片的宽度为1000mm以上、在沿着宽度方向的位置中的单体透射率的最大值与最小值之差为0.3%以下。
