Abstract:
Provided is a liquid crystal display apparatus including: a liquid crystal panel including a pair of substrates; a liquid crystal layer sandwiched by the pair of substrates; plural electrodes formed on at least one of the pair of substrates; and a pair of polarizers provided in respective outsides of the pair of substrates; and a back light unit provided in a rear of the liquid crystal panel, in which one of the pair of polarizers, which is provided at a side of the back light unit, includes at least two types of layers which cause polarization, and in which the two types of layers include a first layer provided on a side of the liquid crystal layer and a second layer provided on a side of the back light unit, the first layer being a negative uniaxial polarizer layer, the second layer being a positive uniaxial polarizer layer.
