Abstract: A display device includes a first substrate including a first emission area, a second emission area, and a third emission area, each of which is to emit a first light; a second substrate having a first surface facing the first substrate and a second surface opposite to the first surface; a first color filter, a second color filter and a third color filter, and a first wavelength conversion pattern, a second wavelength conversion pattern and a light-transmitting pattern on the first surface of the second substrate. A thickness of the first color filter is greater than a thickness of the second color filter and the thickness of the second color filter is greater than a thickness of the third color filter.
