1. A display panel comprising:
an array substrate comprising an inorganic insulating film that is provided above a substrate and positioned in a display region and a frame region surrounding the display region;
a first wiring line and a second wiring line that are formed at an interval on the inorganic insulating film and positioned in the frame region;
an organic insulating film that is provided above the inorganic insulating film, is positioned in the display region and the frame region and completely covers the first wiring line and the second wiring line;
a slit that is formed to extend through the organic insulating film between the first wiring line and the second wiring line, each portion of the slit being arranged parallel to at least one of the first wiring line and the second wiring line, each portion of the first wiring line and the second wiring line being outside of, and separated from, the slit, and the slit being filled with a moisture-proof member that is in contact with the inorganic insulating film; and
a counter substrate that is arranged to face the array substrate with a gap,
wherein
the first wiring line is adjacent to the second wiring line,
the first wiring line is a power supply wiring line positioned on a side of the display region with respect to the slit,
the second wiring line is a control signal wiring line positioned on an outer edge side of the array substrate with respect to the slit, and
the slit has a width of 5 to 10 μm.
