A display device comprises a first substrate, a second substrate, a display medium layer disposed between the first and second substrates, and a light-shielding pattern disposed between the first and second substrates. The second substrate comprises a plurality of conductive wires. One of the conductive wires is projected onto the light-shielding pattern along a first direction, thereby obtaining a projected line within the light-shielding pattern. The projected line comprises a curved portion and two extending portions respectively connected to two ends of the curved portion. A distance between an edge of the light-shielding pattern and the curved portion of the projected line along a second direction is not equal to a distance between the edge of the light-shielding pattern and one of the extending portions along the second direction. The first direction is perpendicular to the second direction.
