Organic light emitting diode (OLED) display device

An organic light emitting diode (OLED) display device, comprising:

• a thin film transistor substrate including a first substrate, a thin film transistor disposed on the first substrate and a WOLED connected to the thin film transistor;
• a color filter substrate including a second substrate that faces the first substrate, and red, green and blue color filters disposed on the second substrate;
• a silica aerogel film having a plurality of pores formed on the red, green and blue color filters, the silica aerogel film disposed in an integrated structure between the color filter substrate and the thin film transistor substrate;
• and
• a quantum dot pattern disposed on the silica aerogel film, the quantum dot film disposed between the thin film transistor substrate and the reflective film, wherein the plurality of pores in the silica aerogel film therein which reflect an unabsorbed light from the quantum dot pattern into the quantum dot pattern.
