1. A liquid crystal device, comprising:
a first substrate including a scanning line and a data line intersecting with the scanning line to define a pixel, said pixel comprising a switching element, a pixel electrode and a storage capacitor;
a second substrate opposing the first substrate; and
liquid crystal interposed between the first substrate and the second substrate;
wherein
a region where the pixel electrode is provided includes a reflective region and a transmissive region;
an insulation layer is provided in the reflective region and the transmissive region to cover the switching element;
a liquid crystal thickness adjustment layer is provided on the insulation layer in the reflective region;
the pixel electrode comprises a first pixel electrode portion provided on the insulation layer in the transmissive region, and a second pixel electrode portion provided on the liquid crystal thickness adjustment layer in the reflective region;
the storage capacitor includes a first capacitor electrode which is disposed on the insulation layer in the reflective region and is electrically connected to the pixel electrode, and a second capacitor electrode opposing the first capacitor electrode with the insulation layer disposed therebetween;
the first capacitor electrode is an extension of the first pixel electrode portion into the reflective region where said extension is located between the insulation layer and the liquid crystal thickness adjustment layer; and
the first pixel electrode portion is electrically connected to the second pixel electrode portion.
