Display device

A display device comprising a display panel and a flexible printed circuit board electrically connected to the display device, the flexible printed circuit board including a base material with a connection terminal and a signal wiring formed thereon, a first cover layer disposed on a first side of the base material, and a second cover layer disposed on a second side different from the first side of the base material,

• wherein the connection terminal and the signal wiring are formed on the first side of the base material;
• the display panel is connected to the connection terminal;
• the first cover layer is spaced from an end portion of the display panel by a gap of a predetermined size thereby leaving at least one of the connection terminal and the signal wiring exposed;
• the second cover layer overlaps with the gap in a planar view;
• a first end portion of the first cover layer is disposed on a side of the gap and faces an end side of the display panel;
• a shape of the first end portion is formed linearly;
• a second end portion of the second cover layer is disposed on an opposite side the display panel;
• a shape of the second end portion is formed to be wavy or concavo-convex including crests and troughs, and
• the first end portion is positioned between the crests and the troughs in a planar view.
