1. A light emitting module comprising:
a mounting substrate;
a plurality of light emitting chips mounted on the mounting substrate; and
a plurality of pads disposed between the light emitting chips and the mounting substrate,
wherein:
the light emitting chips comprise:
a first substrate;
a first light emitting unit disposed on a first surface of the first substrate;
a second substrate spaced apart from the first substrate; and
a second light emitting unit disposed on a second surface of the second substrate;
the first substrate includes a first side surface comprising a first modified surface, and the second substrate includes a second side surface facing the first side surface of the first substrate and comprising a second modified surface;
the first modified surface comprises first modified regions extended in a thickness direction of the first substrate and first ruptured regions disposed between the respective first modified regions;
the second modified surface comprises second modified regions extended in a thickness direction of the second substrate and second ruptured regions disposed between the respective second modified regions; and
the first ruptured regions of the first modified surface have the same width as the second ruptured regions of the second modified surface.
