DISPLAY DEVICE

A display device may include: a display panel; and a signal transmission film including: a first extension portion extending in a first direction and forming a first contact hole in a first side portion; a second extension portion extending from a first side portion of the first extension portion in a second direction different from the first direction; and a first dummy pattern disposed adjacent to the first contact hole at the first side portion, the signal transmission film being connected to one side of the display panel. Therefore, during the bending period of the signal transmission film, the upper protective film and the signal transmission film are not separated at the first side portion, and the bad arrangement of the signal transmission film can be prevented. 显示装置可以包括：显示面板；以及信号传送膜，包括：第一延伸部，向第一方向延伸，并在第一侧部形成第一接触孔；第二延伸部，从第一延伸部的第一侧部向与第一方向不同的第二方向延伸；以及第一虚设图案，在第一侧部与第一接触孔相邻配置，所述信号传送膜连接于显示面板的一侧。由此，在信号传送膜被弯曲的期间，上保护膜和信号传送膜在第一侧部可以不分离，可以防止信号传送膜的排列不良。
