A display device includes a first substrate, a second substrate, a display medium layer, and a light-shielding pattern. The second substrate includes a conductive wire. The display medium layer is disposed between the first substrate and the second substrate. The light-shielding pattern is disposed between the first substrate and the second substrate. The conductive wire is projected onto the first substrate along a first direction to obtain a projected line. The projected line includes a first border. The light-shielding pattern includes a first edge. The first edge includes a first curving rim. The first curving rim is adjacent to the first border.
