Abstract
A display device including a color filter is provided. The display device may include at least one color conversion pattern realizing a color same as the color filter. The color conversion pattern may be surrounded by the color filter. Thus, in the display device according to the embodiment of the present disclosure, the color gamut may be improved without increasing the overall thickness of the display device.
Claims20
A display device, comprising:
- a first substrate including a pixel region;
- a second substrate on the first substrate, the second substrate overlapping with the pixel region;
- a color filter between the first substrate and the second substrate, the color filter including a penetrating hole in the pixel region;
- and
- a color conversion pattern in the penetrating hole of the color filter,
- wherein the color conversion pattern realizes a color that is the same as the color filter,
- wherein each of the color filter and the color conversion pattern includes a lower surface facing toward the first substrate, an upper surface facing toward the second substrate, and a side surface between the lower surface and the upper surface,
- wherein an entire of the side surface of the color filter in the penetrating hole of the color filter contacts with an entire of the side surface of the color conversion pattern in the penetrating hole of the color filter,
- wherein the lower surface of the color conversion pattern is disposed outside the lower surface of the color filter in the pixel region, and
- wherein the upper surface of the color conversion pattern is disposed outside the upper surface of the color filter in the pixel region.
