1. A light-emitting module comprising:

  • a light-emitting element;

    a positive temperature coefficient thermistor; and

    a substrate between the light-emitting element and the positive temperature coefficient thermistor,wherein the light-emitting element includes a first electrode, a layer including a light-emitting organic compound over the first electrode and a second electrode over the layer including the light-emitting organic compound,wherein the positive temperature coefficient thermistor includes a third electrode,wherein the light-emitting element and the positive temperature coefficient thermistor overlap each other,wherein the light-emitting element is configured to be supplied with electric power through the positive temperature coefficient thermistor,wherein the positive temperature coefficient thermistor is configured to interrupt or inhibit supply of the electric power to the light-emitting element,wherein the substrate comprises an opening, andwherein the first electrode of the light-emitting element is electrically connected to the third electrode of the positive temperature coefficient thermistor through the opening of the substrate.
