ABSTRACT:
A liquid crystal device includes two substrates sandwiching a liquid crystal layer and has a reflective display area and a transmissive display area. A liquid crystal layer thickness adjusting layer makes a thickness of the liquid crystal layer in the reflective display area smaller than in the transmissive display area. The device performs display by transitioning an alignment of the liquid crystal layer from splay alignment to bend alignment. The liquid crystal layer thickness adjusting layer has a slope inclining from the reflective display area side to the transmissive display side. A pixel electrode electrically connected to a switching element, which is electrically connected to a signal line, are provided on one of the substrates. A slit is formed in the pixel electrode at an area overlapping with the slope in plan view and part of the signal line is projected along at least part of the slit.
