Abstract
A liquid crystal device is constituted by disposing a liquid crystal between a pair of substrates each provided with an electrode, an insulating layer, and an alignment control layer. At least one of the alignment control layers is provided with a surface unevenness effective for suppressing a liquid crystal movement causing the increase in cell thickness. One of the alignment control layers has a surface shape corresponding the surface unevenness but the surface shape is different from that of the other alignment control layer.
Claims18
A liquid crystal device, comprising:
- a pair of substrates disposed opposite to each other each having thereon an alignment control layer, and a liquid crystal disposed between the substrates,
- wherein one of the alignment control layers has an uneven surface provided with a first surface unevenness and the other alignment control layer has a an uneven surface provided with a second surface unevenness different from the first surface unevenness.
