Abstract
In a pair of substrates which sandwich a liquid crystal therebetween, a substrate 2a for a liquid crystal device that is positioned opposite from the viewing side. A pixel electrode 9 is formed on the surface of a base 6a as a light reflecting film. A pattern in which a plurality of convexities 10c are arranged is formed on the surface of the light reflecting film 9. These convexities 10c are formed into rectangular dome shapes such that the spatial shape thereof that extends along one axis of the two orthogonal X, Y axes that pass through said convexities themselves is different from the spatial shape thereof along the other axis. The light reflecting film 9 achieves both light directivity and light scattering.
