Patent ID: 8355101

Claim:
A liquid crystal device, comprising: a first substrate and a second substrate facing each other; a liquid crystal layer disposed between the first substrate and the second substrate; an aligning film which is disposed on a liquid crystal layer side surface of the second substrate and on which a rubbing processing is performed; a plurality of sub-pixels arranged in planar regions of the first substrate and the second substrate; source lines extending in a first direction; gate lines extending in a second direction that is perpendicular to the first direction; and a first electrode and a second electrode which are disposed on a liquid crystal layer side surface of the first substrate and which generate an electric field therebetween, wherein the second electrode includes a plurality of electrode line-shaped portions extending in the second direction, arranged in parallel to each other, and spaced apart from each other, wherein each sub-pixel includes a reflective display region in which a light reflective film is disposed and a transmissive display region in which a light reflective film is not disposed, wherein a layer thickness adjusting film, which allows the liquid crystal layer to have different layer thicknesses in the reflective display region and in the transmissive display region, is disposed between the second substrate and the aligning film, wherein the layer thickness adjusting film is disposed in a band form over a plurality of sub-pixels and extends in the second direction, the layer thickness adjusting film having a step portion with a step plane extending in a thickness direction of the layer thickness adjusting film near boundary portions between the reflective display region and the transmissive display region, wherein an angle between a rubbing direction in which a rubbing processing is performed and an extending direction of a boundary between the reflective display region and the transmissive display region is defined as α, 0°≦α≦20°, wherein ends of liquid crystal molecules, which are on a leading side of rubbing, are arranged so as to direct toward the step plane when a voltage is applied across the first electrode and the second electrode, and wherein the electrode line-shaped portions and the step plane extend in the second direction which is parallel to a lateral direction of the sub-pixels and parallel to the boundaries between the reflective display regions and the transmissive display regions, and an angle between the rubbing direction and the extending direction of the electrode line-shaped portion is defined as β, 5°≦β≦20°.
