1. A display panel comprising a conductive layer including a plurality of wirings laminated onto a substrate, in which the respective wiring is connected to a terminal portion and extends therefrom so as to be electrically connected to an outside circuit at an edge of the display panel, comprising:
- a plurality of slits which are disposed in the wiring between the terminal portion and the edge of the display panel to prevent delamination of the wirings from the substrate in an area adjacent to the terminal portion,wherein the wirings each have a lower surface contacting the substrate and an upper surface opposite to said lower surface,wherein the slits each extend from said upper surface to said lower surface, andwherein the slits include at least a first slit and a second slit, the first slit and the second slit differing from one another in an extending direction.

Abstract
The proceeding of peeling of a conductive layer in the vicinity of terminals is prevented. A display panel includes a conductive layer extending to the outside of terminals, and the conductive layer has slits extending in directions from one end face to the other end face alternately at two end faces along the extending direction of the conductive layer.

15. A display panel comprising:
-
a first substrate and a second substrate, the first substrate including a first region which does not overlap with the second substrate and a second region which overlaps with the second substrate; a plurality of terminals to which a signal is input from an outside circuit, the terminals being formed on the first region of the first substrate; a plurality of conductive layers which are signal lines being formed on the first substrate so as to extend from an end edge of the first substrate in the first region toward the second region; each conductive layer being formed at a lower layer of one of the terminals, and each conductive layer being electrically connected to an associated one of the terminals; wherein each conductive layer is provided with a plurality of slits in the conductive layer between the terminals and the edge of the first substrate to prevent delamination of the wirings from the substrate in an area adjacent to the terminal portion, wherein the conductive layers each have a lower surface contacting the substrate and an upper surface opposite to said lower surface, and wherein the slits include at least a first slit and a second slit, the first slit and the second slit differing from one another in an extending direction. - View Dependent Claims (16, 17, 18, 19, 20, 27)

23. A display panel comprising:
-
a conductive layer including a plurality of wirings laminated onto a substrate, in which at least one wiring is connected to a terminal portion and extends therefrom so as to be electrically connected to an outside circuit at an edge of the display panel, and means for preventing delamination of the wiring from the substrate, the means comprising a plurality of slits which were disposed in the wiring between the terminal portion and the edge of the display panel to prevent delamination of the wirings from the substrate in an area adjacent to the terminal portion, wherein the wirings each have a lower surface contacting the substrate and an upper surface opposite to said lower surface, wherein the slits each extend from said upper surface to said lower surface, and wherein the slits include at least a first slit and a second slit, the first slit and the second slit differing from one another in an extending direction. - View Dependent Claims (24, 28)
