Display panel and display device with same

A display panel, comprising:

• a first substrate having a first surface, the first surface having formed thereon switching elements connected to pixel electrodes and an insulating film covering the switching elements;
• a second substrate having a second surface facing the first surface, the second surface having formed thereon a black matrix layer as a light-shielding layer and an opposite electrode that generates an electric field between the opposite electrode and the pixel electrodes;
• and
• a sealing member disposed between the first substrate and the second substrate along an outer periphery of the second substrate that includes a corner thereof, the sealing member bonding together the first substrate and the second substrate,
• wherein a cut-out is formed in a portion of the insulating film corresponding in position to the corner of the second substrate, and
• wherein cut-outs are respectively formed in a portion of the black matrix layer at the corner of the second substrate and a portion of the opposite electrode at the corner of the second substrate.
