PROBLEM TO BE SOLVED: To provide an electro-optic apparatus in which display brightness in the viewing direction can be improved by preventing the reflected light from scattering in unnecessary directions and enhancing the intensity of light in the necessary direction.;SOLUTION: The directional reflective scattering layer in a reflection type or a transflective electro-optic apparatus is provided with a tilted structure necessary to give directivity to the reflected light. A scattering plate having a rough pattern is disposed on the scattering layer, and further a reflecting plate is disposed thereon. The tilted structure is formed by a photolithographic method. As for the photomask, a halftone mask is used, or the mask has elliptic, circular or drop-like patterns as a mask pattern. By using the photomask to optimize the tilted structure, the display brightness in the viewing direction can be improved. The obtained electro-optic apparatus is bright and excellent in visibility.;COPYRIGHT: (C)2004,JPO
