Patent ID: 7903216

Claim:
A liquid crystal device in which a liquid crystal layer formed of a liquid crystal having a negative dielectric anisotropy is interposed between a first substrate and a second substrate disposed opposite to each other, the liquid crystal device comprising: an alignment film controlling the liquid crystal in a vertical direction at the time of non-applying voltage, the alignment film being disposed between the liquid crystal layer and the first substrate and between the liquid crystal layer and the second substrate; a first wave plate and a first polarizing plate provided on a surface of the first substrate opposite to the liquid crystal layer; a second wave plate and a second polarizing plate provided on a surface of the second substrate opposite to the liquid crystal layer; an alignment control portion provided in both a transmissive display area and a reflective display area of a pixel area, and controlling alignment of the liquid crystal of the liquid crystal layer at the time of applying voltage, the alignment control portion being provided on at least one of the first substrate and the second substrate; and a plurality of island-shaped electrodes including a longitudinal island-shaped electrode being formed in the pixel area and the alignment control portion, extending in the longitudinal direction of the island-shaped electrode, being disposed in a plane area of the longitudinal island-shaped electrode and the liquid crystal therebetween, wherein retardation axes of the first wave plate and the second wave plate are approximately perpendicular to each other, and at least one of the retardation axis of the first wave plate and the retardation axis of the second wave plate is arranged approximately parallel to a main alignment direction of the liquid crystal aligned by the alignment control portion, at least one of the retardation axis of the first wave plate and the retardation axis of the second wave plate is approximately parallel to the extending direction of the alignment control portion, and wherein the alignment control portion includes a plurality of dielectric projections projecting into the liquid crystal layer from an electrode provided on the liquid crystal layer side of one of the first substrate and the second substrate, a first dielectric projection being substantially stripe-shaped and formed in the transmissive display area and a second dielectric projection being substantially circular and formed in the reflective display area.
