Abstract

　本発明は、視認性（光漏れ、色味むら、正面コントラスト）に優れ、かつレターデーションと波長分散性を両立させた光学補償フィルムを提供することにある。また、その光学補償フィルムを用いた偏光板、それを用いることで光漏れを低減し、色味変動や正面コントラストが改善された液晶表示装置を提供する。この光学補償フィルムは、ゴニオフォトメーターの散乱光プロファイルの入射光９０°のフィルムの散乱光強度測定であって、光源から１３０°の位置における散乱光強度を検出する測定する場合において、フィルム遅相軸を水平に試料台へ設置した場合と垂直に設置した場合の散乱光強度差が、０．０５以下であることを特徴とする。
