摘要： An embodiment of a printed circuit board includes a first insulating layer, a metal layer disposed above the first insulating layer, a second insulating layer disposed above the metal layer, and signal lines disposed above the second insulating layer, the signal lines extending in a first direction and having line widths in a second direction perpendicular to the first direction. The metal layer has open areas overlapping the signal lines in a third direction perpendicular to the first and second directions. In another embodiment, the open areas are replaced with metal meshes.

摘要： A backlight unit and a display device including the same are provided. The backlight unit includes a first substrate on which at least one transistor is disposed; a second substrate facing the first substrate; a heat dissipation sheet which is disposed on the second substrate and at least a part of which is in contact with the first substrate; and at least one light source disposed between the heat dissipation sheet and the first substrate and electrically connected to the transistor. The heat dissipation sheet includes a first region in contact with the first substrate and a second region separated from the first substrate, the second region being a region other than the first region.

摘要： The display device includes a display panel, a printed circuit board on which a timing controller is mounted, and a connection film on which a data driver is mounted. Pixels and a gate driving circuit are disposed in a display area of the display panel. The connection film includes output lines connecting the data driver and the display panel, and first connection lines connecting the printed circuit board and the display panel. The first connection lines overlap the first area on which the data driver is mounted and are disposed between the output lines.
