Abstract
A transflective or reflective liquid crystal device includes an element substrate, an opposite substrate, and a liquid crystal layer. A translucent pixel electrode that is electrically connected to a pixel switching element in each of a plurality of pixels and a translucent common electrode that forms a fringe electric field between the pixel electrode and the common electrode are formed so as to overlap each other via a first dielectric layer in plan view in the element substrate. The opposite substrate is arranged so as to face the element substrate. The liquid crystal layer is held between the opposite substrate and the element substrate. A light reflection layer is formed on the element substrate so as to overlap the pixel electrode(s) and the common electrode in plan view in a lower layer below the pixel electrode(s) and the common electrode. The light reflection layer is formed so as to overlap one electrode, which is located on a lower layer side, between the pixel electrode(s) and the common electrode via a second dielectric layer in plan view, and is applied with the same electric potential as that of the other electrode located on an upper layer side. In each of the plurality of pixels, a holding capacitor is formed of a capacitance component formed between the pixel electrode and the common electrode and a capacitance component formed between the one electrode and the light reflection layer.
