    • A phase difference film, a polarizing plate and an LCD device are provided to compensate a liquid crystal cell optically by using the phase difference film and the polarizing plate, thereby improving the display properties of a front direction and an inclination direction by reducing the leakage of light and a change of the feeling of a color in the black-and-white display of the LCD device. A front retardation(Re) of a support member and retardation in a thickness direction(Rth) satisfy an expression of 0
    • 提供了一种相位差膜,偏振片和LCD装置,通过使用相位差膜和偏振板来光学地补偿液晶单元,从而通过减少相位差膜和偏振片的泄漏来改善前方向和倾斜方向的显示特性 光和LCD装置的黑白显示中的颜色感的改变。 支撑构件的前向延迟(Re)和厚度方向的延迟(Rth)满足0 <= Re(630)<= 10和Rth(630)<= 25的表达式。 支撑构件的波长分散性满足Re(400)-Re(700)<= 10和Rth(400)-Rth(700)<= 35的表达式。 支撑构件由纤维素酰化物膜构成。 相位差膜的正面延迟和厚度方向的延迟满足0 <= Re(550)<= 10和100 <= Rth(550)<= 300的表达式。 相位差膜的波长分散性满足1.04≤Rth(450)/ Rth(550)<= 1.30的表达式。
