Zusammenfassung:	PURPOSE: A transparent protective film for a polarizing plate is provided to prevent any troubles related to a saponification treatment. CONSTITUTION: A transparent protective film(3) for the polarizing plate is disposed on at least one surface of a polarizer via an adhesive layer and is characterized by having ratio(oxygen ratio/carbon ratio) of exceeding 0.75 on a surface of the transparent protective film for the polarizing plate soldering to the polarizer measured by X-ray photoelectron spectroscopy. 본 발명은 편광판용 투명 보호 필름의 편광자와 접착하는 면의 X선 광전자 분광법에 의한 구성원소의 비율(산소의 비율/탄소의 비율)이 0.75 초과임을 특징으로 하는, 편광자 표면의 한 면 이상에 접착층이 개재되어 있는 편광판용 투명 보호 필름에 관한 것으로, 상기 필름은 비누화 처리에 따르는 문제점 없이 표면의 접착이 용이하고 변형이 발생하지 않는다.
