Display device

The present invention relates to a display device. The display device includes a display panel, a first circuit board, a control unit disposed on the first circuit board, a second circuit board, and acoupling film which electrically couples the control unit and the second circuit board to each other. The coupling film includes a first coupling part including a first region attached to the first circuit board, and a second region overlapping the display panel when viewed in a thickness direction of the display panel, a second coupling part including a third region attached to the second circuit board, and a fourth region overlapping the display panel when viewed in the thickness direction of the display panel, and a third coupling part coupled to each of the second region and the fourth region to electrically couple the first coupling part and the second coupling part to each other. 本申请涉及种显示设备，所述显示设备包括显示面板、第电路板、控制单元、第二电路板和联接膜，其中，控制单元设置在第电路板上，联接膜将控制单元和第二电路板彼此电联接。联接膜包括第联接部分、第二联接部分和第三联接部分，其中第联接部分包括附接至第电路板的第区域以及当在
