Patent ID: 7499131

Claim:
A liquid crystal display device including a first substrate on which a first electrode is provided, a second substrate on which a second electrode is provided, and liquid crystals filling a space between the first and second substrates, the liquid crystal display device comprising: a first structure provided on the first substrate, the first structure causing liquid crystal molecules in a vicinity of the first structure to align with a first direction when a voltage is applied; and a second structure provided at a position on the second substrate where the second structure is opposed to the first structure, the second structure causing liquid crystal molecules in a vicinity of the second structure to align with a second direction, which is different from the first direction, when the voltage is applied, wherein a relational expression 1<a/b≦9 is satisfied, where a length, measured in a layer thickness direction, of an area where liquid crystal molecules are aligned with the first direction is denoted by a, and a length, measured in the layer thickness direction, of an area where liquid crystal molecules are aligned with the second direction is denoted by b.
