摘要

A display device includes a display panel, a protection film which faces the display panel and includes a first surface closest to the display panel and a second surface which is opposed to the first surface, a first anti-static layer which defines the first surface of the protection film, a second anti-static layer which faces the first anti-static layer and defines the second surface of the protection film, and a polyimide film between the first anti-static layer and the second anti-static layer, and an adhesive layer which forms an interface with the first surface of the protection film and attaches the protection film to the display panel.

說明書

The protection member 4000 may define a preliminary structure including the lower protection film 400. The release film 410 and the carrier film 430 may be removably attached to the lower protection film 400. The lower protection film 400 having the release film 410 and the carrier film 430 removed therefrom is attachable to other layers of the electronic device 1000 (refer to FIGS. 2 and 4), such as by an adhesive layer.

According to one or more embodiment, the lower protection film 400 attached to the rear surface of the display panel 100 may include the base film 401 and anti-static layers disposed on opposing surfaces of the base film 401, respectively. The base film 401 may include BPDA and the filler 401f having the size of about 1 μm. Thus, the base film 401 may have the improved folding characteristic and the increased transmittance. Also, each of the anti-static layers may have the improved coating reliability by including the urethane-based binder.

Also, according to one or more embodiment, each of the anti-static layers may have the surface resistance equal to or less than a predetermined value. Thus, the anti-static function of the anti-static layers may be maintained although the adhesive layer is attached to both the display panel 100 and the anti-static layer. Also, each of the anti-static layers may have the polar surface energy equal to or greater than a predetermined value. Thus, the adhesive layer including a material which is provided contacting the anti-static layer may have the improved coating reliability.
