摘要： 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.

摘要： A color conversion substrate includes a base on which first to third light outputting regions and a light shielding region surrounding the first to third light outputting regions are defined; first to third color filters on the base in the first to third light outputting regions, respectively; a first light shielding member on the first color filter in the light shielding region; a light transmission pattern on the first color filter; a first wavelength conversion pattern on the second color filter and which converts light of a first color into light of a second color; and a second wavelength conversion pattern on the third color filter and which converts the light of the first color into light of a third color. A first opening located in the light shielding region is defined in at least one of the light transmission pattern and the first and second wavelength conversion patterns.
