The present disclosure a biochip including a side emitting-type light-emitting device, in which the bio-chip includes: a light-emitting device for emitting light from a fluorescent material; reflective layers provided over and under the light-emitting device so as to emit light from the sides of the light-emitting device; and reaction regions formed by etching of flanking regions of the light-emitting device. In the biochip, light emitted from the sides of the light-emitting device causes a biochemical reaction in the reaction regions. According to the present disclosure, light emitted from the light-emitting device moves only laterally without being transferred to the top or bottom of the bio-layer, and is transferred to the reaction regions formed by etching of flanking regions of the light-emitting device, so that a biochemical reaction in the reaction regions can be more efficiently performed.
