摘要:
本发明提供一种能够实现视觉辨认性优异的大型液晶面板的偏振板等。偏振板100具备偏振片10及保护膜20。偏振板100的外形形状为具有660mm以上的长边及370mm以上的短边的矩形。偏振板100的平均的偏振度为99.98%以上。偏振度小于99%且最大直径为30μm以上的缺陷部的个数为10个/m2以下。
摘要(英):
Provided is a light polarization plate or the like which is capable of achieving a large liquid crystal panel exhibiting excellent visibility. This light polarization plate 100 is provided with a light polarizer 10 and a protective film 20. The external shape of the light polarization plate 100 is a rectangle having long sides which are at least 660 mm, and short sides which are at least 370 mm. The average light polarization degree of the light polarization plate 100 is at least 99.98%. The number of defects having a light polarization degree of less than 99% and a maximum diameter of at least 30 [mu]m is not more than 10 per m2.
