ABSTRACT:
A liquid crystal display apparatus having a liquid crystal panel including a pair of substrates, a plurality of electrodes formed on at least one of the pair of substrates and a liquid crystal layer sandwiched between the pair of substrates, and a light source provided on one surface of the liquid crystal panel. An electric field in the liquid crystal layer produced by the plurality of electrodes is predominantly in parallel with surfaces of the pair of substrates. The light source has a luminous characteristic with a first chromaticity and the liquid crystal panel has a characteristic of spectral transmittance with a second chromaticity different from the first chromaticity so as to compensate for the color of the light source.
