Abstract: A display device includes a solar cell unit contains an organic-inorganic hybrid perovskite compound and avalanching nano particles to absorb light of small energy and emit light of greater energy, so that a light conversion efficiency of a solar cell can be increased, and the solar cell unit includes an opening for opening sub-pixels and light emitted from the sub-pixels may be emitted to the outside through the opening, so that a decrease in light transmittance caused by the solar cell can be reduced and light transmittance of the display device can be increased.
