1. A light module comprising:
a support substrate;
a light emitter disposed on the support substrate; and
a light guide disposed on the support substrate and covering a side of the light emitter,
wherein the light emitter includes:
an emitter substrate including a first surface and a second surface opposed to the first surface;
a light emitting layer disposed on the first surface of the emitter substrate; and
a light block layer disposed on the second surface of the emitter substrate and configured to prevent light emitted from the light emitting layer from exiting through the second surface of the emitter substrate,
wherein the light emitter comprises a first light profile in a first length direction and a second light profile in a second length direction crossing the first length direction,
wherein the first light profile is different from the second light profile, and
wherein light emitted from the light emitter has an orientation angle equal to or less than about 170 degrees.
