Patent ID: 8796919

Claim:
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.
