Display device
A display device includes a display panel, a support member disposed under the display panel, a circuit board electrically connected to the display panel and disposed under the support member, and a metal sheet disposed between the circuit board and the support member, bonded to the circuit board by a first adhesive film, and bonded to the support member by a second adhesive film.
1 . A display device comprising:
a display panel;
a support member disposed under the display panel;
a circuit board electrically connected to the display panel and disposed under the support member; and
a metal sheet disposed between the circuit board and the support member, bonded to the circuit board by a first electrically conductive adhesive film, and bonded to the support member by a second electrically conductive adhesive film,
wherein the metal sheet, the first electrically conductive adhesive film, and the second electrically conductive adhesive film overlap the circuit board in a cross-sectional view when the display device is in a flat configuration, and
wherein the metal sheet is directly electrically connected to both the circuit board and the support member by the first and second electrically conductive adhesive films, respectively.
2 . The display device of claim 1 , wherein
the circuit board includes:
a ground wire electrically connected to the metal sheet; and
a cover layer disposed between the metal sheet and the ground wire and including an opening which exposes a portion of the ground wire, and
the metal sheet is bonded to the cover layer by the first electrically conductive adhesive film.
3 . The display device of claim 2 , wherein
the circuit board further includes a step compensation film, and
the step compensation film is disposed to correspond to the opening and electrically connects the metal sheet and the portion of the ground wire exposed by the opening.
4 . The display device of claim 3 , wherein the step compensation film includes:
a conductive film; and
a conductive tape disposed between the conductive film and the metal sheet.
5 . The display device of claim 1 , wherein each of the first electrically conductive adhesive film and the second electrically conductive adhesive film is a double-sided adhesive film.
6 . The display device of claim 1 , wherein each of the first electrically conductive adhesive film and the second electrically conductive adhesive film is an anisotropic conductive adhesive film.
7 . The display device of claim 1 , further comprising:
a panel driving chip overlapping the support member, wherein
the display panel includes:
a first area which emits light;
a second area extending from the first area and bent with a curvature; and
a third area extending from the second area and overlapping the support member, and
the panel driving chip is mounted on the third area of the display panel.
8 . The display device of claim 1 , further comprising:
a flexible circuit film electrically connecting the display panel and the circuit board and overlapping the support member; and
a panel driving chip mounted on the flexible circuit film and overlapping the support member.
