Abstract:
The liquid crystal panel according to an embodiment of the present invention includes a liquid crystal cell, a first polarizing plate placed on one side of the liquid crystal cell, a second polarizing plate and a third polarizing plate placed on the other side of the liquid crystal cell in an order starting from a side of the liquid crystal cell, and a retardation plate (A) placed between the liquid crystal cell and the second polarizing plate, wherein a refractive index ellipsoid of the retardation plate (A) has a relationship of nx≧ny>nz, a difference (ΔT2−1=T2−T1) between a transmittance (T2) of the second polarizing plate and a transmittance (T1) of the first polarizing plate is larger than 0%, a difference (ΔT3−2=T3−T2) between a transmittance (T3) of the third polarizing plate and a transmittance (T2) of the second polarizing plate is 4.0% to 7.5%, and the third polarizing plate is a linearly polarized light separation type reflective polarizing plate.
