Abstract
Provided is an electro-optical device which allows high-speed response and has high luminance and contrast. The electro-optical device includes: a plurality of substrates opposed to each other; a medium layer sandwiched between the substrates; electrode groups formed on opposed surfaces of the substrates, for applying an electric field to the medium layer, the electrode groups having a portion in which the electrode groups have an interdigit shape and are arranged substantially parallel; and a pair of polarizing plates which are arranged so that absorption axes thereof are substantially orthogonal to each other with the medium layer sandwiched therebetween, in which the medium layer includes a medium substantially having optical-isotropy with absence of an electric field and exhibiting optical-anisotropy with an applied electric field, the electrode groups include transparent electrodes, and the optical-anisotropy is imparted near the respective electrodes in a direction normal to the substrates by the electrode groups.
