ABSTRACT:
A liquid crystal display device may include a first substrate; a second substrate; a first polarizing plate on the first substrate; a second polarizing plate arranged on the second substrate, and so that a direction of an absorption axis of the second polarizing plate being perpendicular to a direction of an absorption axis of the first polarizing plate; a liquid crystal layer arranged between the first substrate and the second substrate; a color filter layer arranged between the liquid crystal layer and the first or the second substrate, the color filter layer having a plurality of pixels of two or more colors. The retardation thin film has in-plane birefringence index satisfying 0.75≦Δn[fr]/λd[fr]≦1.35 for a region corresponding to a reflection part of a pixel and satisfying Δn[t]<1.2 ×10−3for a region corresponding to a transmission part of a pixel.
