Patent ID: 7995176

Claim:
A liquid crystal display device comprising: a first substrate that has electrodes provided at regular intervals to apply a voltage to liquid crystal; a second substrate that has an electrode to apply the voltage to the liquid crystal; a liquid crystal layer that is held between said first substrate and said second substrate and is made of the liquid crystal, the liquid crystal being aligned in a substantially vertical direction with respect to a substrate plane and of a negative type; a first polarizing plate that is provided at a side which is different from a liquid crystal side of said first substrate; a second polarizing plate that is provided at a side which is different from a liquid crystal side of said second substrate, and has a transmission axis which is orthogonal to a transmission axis of said first polarizing plate; a first retardation plate that is provided between said first substrate and said first polarizing plate, and has a slow axis which is not parallel or orthogonal to the transmission axis of said first polarizing plate; a second retardation plate that is provided between said first substrate and said first retardation plate; a third retardation plate that is provided between said second substrate and said second polarizing plate, and has a slow axis which is orthogonal to the slow axis of said first retardation plate; a fourth retardation plate that is provided between said second substrate and said third retardation plate, and has a slow axis which is orthogonal to a slow axis of said second retardation plate; a control structure that is provided at each of or one of the liquid crystal side of said first substrate and the liquid crystal side of said second substrate, and is configured to control a tilt direction of the liquid crystal upon application of the voltage to said liquid crystal layer; a first domain where the liquid crystal is configured to tilt in one direction upon application of the voltage to said liquid crystal layer; and a second domain where the liquid crystal is configured to tilt in a direction which is different from the tilt direction of the liquid crystal in said first domain by substantially 180°, wherein an angle formed by the tilt direction of the liquid crystal in said first domain and a horizontal direction of a screen in said liquid crystal display device falls within a range between 22° and 39° or a range between 51° and 68°.
