Abstract: A display module includes a display panel with a plurality of bonding electrodes arranged at intervals along a selected side edge of a non-display surface and divided into two bonding electrode groups, a first flexible circuit board and a second flexible circuit board. For the first flexible circuit board, each first conductive contact piece in a first wiring region is connected to a bonding electrode in a first bonding electrode group. For the second flexible circuit board, each second conductive contact piece in a second wiring region is connected to a bonding electrode in a second bonding electrode group. The first wiring region is closer to the selected side edge than the second wiring region in a first direction. The first fan-out region is spaced apart from the second wiring region in a second direction perpendicular to the first direction.
