Abstract
Provided is a light emitting diode (LED) substrate. The LED substrate includes a substrate of a rectangular shape having sides in a first direction and a second direction, a plurality of LED devices placed on a surface of the substrate, and a plurality of conducting member which electrically connects the plurality of LED devices on the surface of the substrate and forms 2n circuits independent from each other in the first direction. Each circuit has a first electrode part and a second electrode part. The first electrode part receives input of an electric current from the outside, the second electrode part outputs an electric current to the outside, and the first electrode part and the second electrode part face each other in the second direction, and are alternately placed in the first direction to be point-symmetrical with respect to a center of the substrate as a symmetry point.
