Abstract
An organic light emitting diode (OLED) display device includes a thin film transistor substrate including a first substrate, a thin film transistor disposed on the first substrate and a white organic light emitting diode (WOLED) electrically connected to the thin film transistor; a color filter substrate comprising a second substrate that faces the first substrate, and red, green and blue color filters disposed on the second substrate; a quantum dot pattern disposed on the WOLED of the thin film transistor substrate; and a refractive film disposed between the color filter substrate and the thin film transistor substrate provided with the quantum dot pattern.
