Liquid crystal panel capable of indicating black without dependency of visual angle |
摘要 |
A liquid crystal panel has a first layer of liquid crystal sandwiched between an upper substrate and a lower substrate and oriented in a first direction included within a plane substantially parallel to at least one of the upper substrate and the lower substrate. Liquid crystal molecules of the first liquid crystal in proximity of the upper substrate has a tilt angle in a reversed direction to that of liquid crystal molecules of the first liquid crystal in proximity of the lower substrate. A second layer of parallel-oriented liquid crystal is located in parallel to the first liquid crystal layer and has an orientation direction which is included within a plane of the second layer and is orthogonal to the first direction.
