Patent ID: 8294860

Claim:
A liquid crystal display device, comprising: a first substrate and a second substrate; a liquid crystal layer sandwiched between said first and second substrates, in which liquid crystal molecules are vertically aligned with respect to said first and second substrates in a state where no voltage is applied between said first and second substrates; a thin film transistor provided on said first substrate and including a gate, a source, and a drain, a gate line connected to the gate of said thin film transistor; a data line connected to the source of said thin film transistor; a pixel electrode in a comb or a slit shape connected to the drain of said thin film transistor, directions of comb teeth or slit thereof, with the right direction on a screen being 0 degrees, extending in four directions of 45 degrees, 135 degrees, 225 degrees and 315 degrees; a color filter layer formed on said first substrate; a pair of polarizers sandwiching said first and second substrates therebetween; and at least one retardation film provided between said first or second substrate and one of the pair of polarizers, said retardation film having an in-plane retardation set to 40 nm or more to 130 nm or less.
