PURPOSE: An organic light emitting display device is provided to improve an aperture ratio by simplifying the circuit structure of an image domain. CONSTITUTION: An offset control part(32) calculates and stores offset information based on threshold voltage. A data control part(36) generates a second image signal after reflecting the offset information in a first image signal. A gain control part(34) generates an inclination based on first and second voltage. The gain control part calculates gain information based on the calculated inclination.
