Abstract
An opening formed on a transflective film is close to the edge of a rectangular pixel region. An interval tbetween three sides of the four sides of the opening and the edge of the pixel region is smaller than the width of one concave portion formed on the transflective film thereby permitting the concave portions that contribute the least to reflection to be minimized, and the reflectance of the transflective film to be maximized. The desired reflection characteristic can be obtained using a predetermined number of concave portions.
