1. A display device comprising:
a substrate of a display panel including a display area in which an image is displayed and a non-display area adjacent to the display area, the substrate comprising:
an upper surface disposed in both the display area and the non-display area;
a lower surface facing the upper surface, disposed in both the display area and the non-display area; and
a side surface disposed between the upper surface and the lower surface;
a signal line which receives a signal at the non-display area and provides the received signal to the display area, the signal line disposed on the upper surface of the substrate; and
a connection electrode disposed on the upper surface of the substrate in the non-display area thereof,
wherein the connection electrode electrically connects to the signal line,
wherein in the non-display area, the substrate further comprises:
a first portion recessed from the side surface, and
a second portion extending from the first portion toward the signal line, and
wherein the connection electrode is disposed in the first portion and the second portion.
 
10. A display device comprising:
a substrate of a display panel including a display area in which an image is displayed and a non-display area adjacent to the display area, the substrate comprising:
an upper surface disposed in both the display area and the non-display area;
a lower surface facing the upper surface, disposed in both the display area and the non-display area;
a side surface disposed between the upper surface and the lower surface; and
an inclined surface disposed between the side surface and the upper surface,
a signal line which receives a signal at the non-display area and provides the received signal to the display area, the signal line disposed on the upper surface of the substrate; and
a connection electrode disposed on the side surface of the substrate in the non-display area thereof,
wherein the connection electrode electrically connects to the signal line.
 
14. A display device comprising:
a substrate of a display panel including a display area in which an image is displayed and a non-display area adjacent to the display area, the substrate comprising:
