The present invention can reduce the warping of the printed circuit board of a display device. This advantage can be obtained by providing a display device which includes a display element; a printed circuit board which is arranged in a state that the printed circuit board extends over a peripheral portion of the display element; and a plurality of flexible printed circuit boards which connect the display element and the printed circuit board, wherein the printed circuit board is connected with the plurality of flexible printed circuit boards using a plurality of connection terminal groups corresponding to the plurality of flexible printed circuit boards, dummy terminal groups are provided between the plurality of connection terminal groups, and the dummy terminal groups are arranged on a side close to the display element side and a side remote from the display element side in the direction orthogonal to the extension direction of the printed circuit board in a state that respective dummy terminal rates are made close to each other.
