Abstract
A display element () includes an upper substrate (first substrate) (), a lower substrate (second substrate) (), and a conductive liquid () that is sealed in a display space (S) formed between the upper substrate () and the lower substrate () so as to be moved toward an effective display region (P) or a non-effective display region (P). The conductive liquid () is colored black. The non-effective display (P) is defined by a black matrix (light-shielding layer) () provided on the upper substrate (), and the effective display region (P) is defined by a color filter (aperture) () formed in the black matrix (). The size of the black matrix () is determined based on the size of each of ribs () and a gap size (H) between the upper substrate () and the lower substrate ().
