Abstract: A display module includes a display panel for displaying an image, and a protective film adhered to a back surface of the display panel. The protective film includes a compensation layer being in contact with the back surface of the display panel, a first release layer disposed under the compensation layer, a cushion layer disposed under the first release layer, and a second release layer disposed under the cushion layer. An adhesive strength of the first release layer is less than an adhesive strength of the second release layer.

Abstract: A printed circuit board assembly includes: a first signal terminal row including a plurality of first signal terminals connected to a plurality of signal wirings of a flexible printed circuit board (FPCB), respectively; a first ground terminal row spaced from the first signal terminal row and including a plurality of first ground terminals connected to a plurality of ground wirings of the FPCB, respectively; a second signal terminal row including a plurality of second signal terminals connected to a plurality of signal wirings of a printed circuit board (PCB), respectively; and a second ground terminal row spaced from the second signal terminal row and including a plurality of second ground terminals connected to a plurality of ground wirings of the PCB, respectively. The first ground terminal row is closer to an end portion of the FPCB than the first signal terminal row.
