Light emitting sheet having high dielectric strength properties and capable of suppressing failures

A light-emitting sheet, comprising:

• a first electrode;
• a second electrode;
• and
• a light-emitting layer disposed between the first and the second electrodes,
• wherein:
• at least one electrode selected from the group consisting of the first electrode and the second electrode is disposed on and under a periphery of the light-emitting layer is divided into a non-conductive portion, which is electrically disconnected from a circuit that applies a voltage to the light-emitting sheet, and a conductive portion;
• the non-conductive portion and the conductive portion of the at least one electrode are separated by a cut section that is obtained by cutting the at least one electrode such that the electrode is cut without completely cutting the light emitting layer;
• the cut section is located inside the end of the light-emitting layer;
• a creepage distance between an edge of the conductive portion of the first electrode and an edge of the conductive portion of the second electrode is 2 mm or more;
• and
• when viewing the light emitting sheet from a vertical direction to a plane of the light-emitting sheet, the non-conductive portion of the first electrode or the non-conductive portion of the second electrode surrounds the light-emitting layer, or the non-conductive portion of the first electrode and the non-conductive portion of the second electrode are apparently connected to each other and surround the light-emitting layer.
