Abstract: An organic light-emitting display device having improved display quality, the organic light-emitting display device may include pixels coupled to scan lines and data lines. Each of the pixels may include a storage unit configured to store a data signal supplied to the data lines. The capacitance of the storage unit may be changed depending on a driving frequency.
