Abstract
A matrix-type liquid crystal device is formed so as to have a matrix of pixels defined by and isolated from each other by an outside-pixel region. The liquid crystal in the outside-pixel region in placed in an alignment state, typically a homeotropic state or one close thereto, which is different from an alignment state, typically a homogeneous uniform alignment state, at the pixel region. As a result, the liquid crystal device is provided with improved display qualities due to suppression of irregularities at the outside-pixel region and/or a local pressure distribution.
