Abstract
A light-emitting sheet including: a first electrode; a second electrode; and a light-emitting layer disposed between the first and the second electrodes, where the first electrode and/or the second electrode disposed on and under the periphery of the light-emitting layer arc cut to form a non-conductive portion being electrically disconnected with a circuit that applys a voltage to the light-emitting sheet, and as seen from a vertical direction to the plane of the light-emitting sheet, the non-conductive portion formed from the first electrode or the non-conductive portion formed from the second electrode surrounds the light-emitting layer, or the non-conductive portion formed from the first electrode and the non-conductive portion formed from the second electrode are apparently connected to each other and surrounds the light-emitting layer.
