A display module includes a display panel which includes a substrate and a periphery circuit. The substrate has a display area and a strip region beside the display area. The substrate is bent with respect to an axis to form a curved shape. The maximum value of the curvature of the display area in a direction perpendicular to the axis is a first curvature. The periphery circuit is disposed on the strip region. The strip region in a direction perpendicular to the axis has a second curvature smaller than the first curvature.
