<P>PROBLEM TO BE SOLVED: To provide a liquid crystal display device with a high contrast ratio in a front direction. <P>SOLUTION: This polarizing plate set comprises a first polarizing plate and a second polarizing plate and is disposed on a liquid crystal panel of normally black type. The first polarizing plate includes a first polarizer, and a first protective layer disposed on one side of the first polarizer. An index ellipsoid of the first protective layer represents a relation of nx>ny>nz, a transmittance (T<SB POS="POST">1</SB>) of the first polarizing plate is larger than a transmittance (T<SB POS="POST">2</SB>) of the second polarizing plate, a difference (ΔT=T<SB POS="POST">1</SB>-T<SB POS="POST">2</SB>) between the transmittance (T<SB POS="POST">1</SB>) of the first polarizing plate and the transmittance (T<SB POS="POST">2</SB>) of the second polarizing plate is 0.1%-2.0%, and the degree of polarization of the first polarizing plate and the second polarizing plate is 99.8% or more. <P>COPYRIGHT: (C)2012,JPO&INPIT |
