Abstract

An electrophoretic display (1) includes: a first substrate (10) and a second substrate (20) facing each other; a base portion (11) provided on the second substrate side of the first substrate; a first concave portion (90) provided such that a surface of the second substrate side of the base portion is recessed, and a second concave portion (91) having a shallower depth than that of the first concave portion; a reflection plate (13) provided on the surface except for the first concave portion and the second concave portion; a first electrode (19a) provided in a bottom surface of the first concave portion; a second electrode (19b) provided in a bottom surface of the second concave portion; a third electrode (21) provided in the first substrate side of the second substrate; and a dispersion liquid (60) filled between the first substrate and the second substrate, in which electrophoretic particles (61) having a different color from that of the reflection plate are dispersed in a dispersing medium (62).
