An organic light-emitting diode display device can include a substrate including first, second and third sub-pixels, each of the first, second and third sub-pixels including an emission area and a non-emission area; a driving thin film transistor in the non-emission area of each of the first, second and third sub-pixels; a light-emitting diode connected to the driving thin film transistor; a polarizer at an outer surface of the substrate, the polarizer including a reflective polarizer; and a light control pattern disposed inside of the substrate and corresponding to the non-emission area, the light control pattern being configured to change a direction of light incident on the light control pattern.
