Abstract

　本発明の液晶パネル（１）は、液晶セル（２）と、液晶セル（２）の一面側に設けられた第１の偏光子（３１）と、液晶セル（２）の他面側に設けられた第２の偏光子（４１）と、第１の偏光子（３１）及び第２の偏光子（４１）の間に設けられた第１の光学補償層（５）及び第２の光学補償層（６）と、を備え、この液晶セル（２）が、０．８＜Ｒｅ［４５０］／Ｒｅ［５５０］＜１の関係を満たし、第１の光学補償層（５）が、Ｎｚ係数０．８～１．４で且つ０．８＜Ｒｅ［４５０］／Ｒｅ［５５０］＜１の関係を満たし、第２の光学補償層（６）が、ｎｘ＝ｎｙ＞ｎｚで且つ０．９８＜Ｒｅ［４５０］／Ｒｅ［５５０］＜１．０４の関係を満たしている。本発明の液晶パネルは、全方位方向及び極角方向から見た場合でも、カラーシフトが生じにくい。このため、該液晶パネルは、極めて優れたカラー表示特性を有する。
