摘要： The invention provides a thin reflective plate having cholesteric liquid crystal that can prevent or reduce a decrease of reflection efficiency. A reflective plate includes a cholesteric liquid crystal layer, and the cholesteric liquid crystal layer includes a plurality of regions in which the helical axes of the cholesteric liquid crystal are aligned in different directions in the plane of a substrate, and therefore, the regions can reflect color light components having different wavelengths. Consequently, the cholesteric liquid crystal layer can reflect light formed of light components of different colors (for example, white light) as a whole. When the reflective plate is applied to a reflective liquid crystal display device or the like, it is possible to appropriately reflect white light for display.

摘要： 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.
