ABSTRACT:
The invention provides a reflection type liquid crystal device, and a projection type display and electronic equipment in which display defects caused by disclination are reduced, minimized or prevented from being produced for a highly fine liquid crystal display with a space between pixels made to be narrow to make it possible to provide a high-contrast and bright display. A liquid crystal device includes a liquid crystal layer sandwiched between a first substrate and a second substrate, and a first electrode and a second electrode formed on a face of the above-described second substrate on a side of the above-described liquid crystal layer. The above-described first electrode and the above-described second electrode are formed so that an electric field substantially parallel to the surface of the substrate with respect to the above-described liquid crystal layer can be applied thereto. The above-described first electrode is formed in a linear shape having a specified line width on the above-described second electrode with a second insulation film interposed therebetween. The above-described second electrode is formed in a rectangular shape, and at least one of the above-described first electrode and the above-described second electrode is a reflecting electrode that causes incident light coming from a direction of the above-described first substrate.
