Abstract: A flexible display device includes a polarizing plate disposed on a display panel; a cover glass attached to the polarizing plate with an adhesive layer interposed therebetween; a back plate disposed on a rear surface of the display panel; and a fixing tape disposed on an edge of a rear surface of the cover glass, wherein the adhesive layer protrudes more than the display panel, the polarizing plate, and the back plate at corner regions of the flexible display device. Thus, the flexible display device provides effects of improving product quality by improving waterproof performance and minimizing chemical contamination.

Abstract: Disclosed are a cushion plate and a display device including the same. The cushion plate includes an impact-absorbing layer disposed on a back surface of a display panel, a first metal layer disposed on upper portion of the impact-absorbing layer, and a second metal layer formed on upper portion of the first metal layer and having a higher thermal conductivity than the first metal layer. The impact-absorbing layer, the first metal layer, and the second metal layer have a first curvature area, and at least one perforated pattern is defined in an area of the first metal layer corresponding to the first curvature area.

Abstract: Disclosed is an electronic device in which a defect, where air bubbles occur in an OCR or a gap space is not filled in a D/B process, is prevented and a gap filling tape is adhered to a display module without a gap, thereby solving a problem where a crack or yellowing occurs in the display module. The electronic device includes a display panel including a first substrate and a second substrate bonded to a portion other than one edge of the first substrate, a panel supporting part supporting the display panel, a cover window attached on a front surface of the second substrate, a housing accommodating the panel supporting part and supporting the cover window, a gap between the one edge of the first substrate and the cover window, and a gap sealing member attached on a side surface of the panel supporting part to seal the gap.
