    • The present invention provides a liquid crystal display device which can provide sufficient contrast. The liquid crystal display device of the present invention is a liquid crystal display device having a structure in which a liquid crystal layer is interposed between a rear substrate and a front substrate, wherein the liquid crystal display device includes a first polarizing layer between the rear substrate and the liquid crystal layer, and the first polarizing layer is arranged between the liquid crystal layer and a depolarization part such as a thin film transistor, a wiring, a color filter, a pixel electrode, and a structure providing a rear face-side surface of the liquid crystal layer with an irregularity.

    • The inventive liquid crystal device is driven in circular polarization mode. A protection plate (22) is provided with a first optical member where a first polarizing plate (23) and a first wave plate (24) are laid in layers sequentially in the order of the first phase difference plate and the first polarizing plate from the side close to a liquid crystal display panel. Optical conditions of the first optical member are designed such that the incident light from the observer side becomes elliptically polarized light having an ellipticity of 0.4-1.0 when it passed through the protection plate and the first optical member and the elliptically polarized light impinges on the liquid crystal layer. Consequently, surface reflection on each substrate and film in the liquid crystal display can be reduced effectively.
    • 本发明的液晶装置以圆偏振模式驱动。 保护板(22)设置有第一光学构件,其中第一偏振片(23)和第一波片(24)按照第一相差板和第一偏振片的顺序依次铺设 靠近液晶显示面板。 第一光学构件的光学条件被设计成使得当来自观察者侧的入射光在通过保护板并且第一光学构件和椭圆偏振光照射在液体上时变为具有0.4-1.0的椭圆率的椭圆偏振光 晶体层。 因此,可以有效地降低液晶显示器中的每个基板和膜上的表面反射。
