Abstract
A light-emitting module according to an embodiment includes a plurality of light-emitting elements, light-guiding plates each having a light-exiting surface, and a wiring layer connected to electrodes of the plurality of light-emitting elements on a surface opposite to the light-exiting surface. The wiring layer includes a first terminal, a second terminal, a first wiring pattern connecting the first terminal and the second terminal, a second wiring pattern connecting the first terminal and the second terminal, a third wiring pattern disposed between the first wiring pattern and the second wiring pattern to connect the first terminal and the second terminal, a fourth wiring pattern connecting the first to third wiring patterns in parallel, the fourth wiring pattern being connected to the first terminal, and a fifth wiring pattern connecting the first to third wiring patterns in parallel, the fifth wiring pattern being connected to the second terminal.
