A photobioreactor for a large-scale microalgal culture. The photobioreactor includes a plurality of surface-light-source assemblies using a light emitting diode (LED) element, an organic light emitting diode (OLED) element, or a flexible LED sheet as a light source. The surface-light-source assemblies have the shape of a flat plate or a cylinder, are installed at predetermined intervals in the interior space of a reaction tank having the shape of a cube or a cylinder, and emit light for culturing microalgae in an internally illuminated fashion. Here, the surface-light-source assemblies are installed in such a manner that they are alternately in contact with first and second walls of the reaction tank disposed in parallel to each other in a symmetrical shape, and serve as partitions that portion the interior space of the reaction tank and increase a flow distance of gas.
