Abstract: Provided is a display device. The display device includes a first substrate and a second substrate including a display area and a non-display area surrounding the display area. The first substrate and the second substrate face and are attached to each other. A first polarizer is disposed on the display area of the first substrate. A second polarizer is entirely disposed on the display area and the non-display area of the second substrate and has a non-overlapping region which does not overlap the first polarizer in the non-display area. A light leakage prevention pattern is disposed between the first substrate and the second substrate in the non-overlapping region of the first polarizer and the second polarizer and includes a color filter pattern and a light blocking pattern which overlap each other.
