Display device

The invention provides a display device. The display device includes a substrate including a display portion having a first width in a first direction and a pad portion protruding from the display portion in a second direction crossing the first direction and having a second width in the first direction, the second width being smaller than the first width; and a printed circuit board adjacent to the substrate in the second direction and having a concave-convex shape toward the substrate. Since the printed circuit board has a concave-convex shape, a dead zone of the display device is reduced. 本发明提供了显示装置。该显示装置包括：基板，包括在第一方向上具有第一宽度的显示部分以及在与第一方向交叉的第二方向上从显示部分突出并且在第一方向上具有第二宽度的焊盘部分，第二宽度小于第一宽度；以及印刷电路板，在第二方向上与基板相邻并且具有朝向基板的凹凸形状。由于印刷电路板具有凹凸形状，因此减小了显示装置的死区。
