An organic light emitting display device includes a first substrate, a second substrate opposite from the first substrate, a plurality of organic light emitting elements on the first substrate, and a color filter on the organic light emitting elements, wherein a transmission wavelength band of the color filter has an upper limit value for transmitting a light wavelength corresponding to a first intensity of a light emitted from the organic light emitting elements at a viewing angle of about 0°, and has a lower limit value for transmitting a light wavelength corresponding to a second intensity that is less than the first intensity.
