1. A display device comprising:
a first substrate;
a pixel structure disposed on the first substrate;
a first optical filter disposed on the pixel structure;
a first color filter disposed on the first optical filter, having a first color, and having a first refractive index;
a second optical filter disposed on the pixel structure, spaced from the first optical filter, and including a pigment having a second color;
a second color filter disposed on the second optical filter, having the second color, and having a second refractive index; and
a second substrate disposed on the first color filter and the second color filter,
wherein the second substrate has a third refractive index, and
wherein a difference between the third refractive index and the second refractive index is less than a difference between the third refractive index and the first refractive index color,
wherein at least one end of the first color filter overlaps at least one end of the second color filter to form an overlapping portion, and
wherein a light blocking member is disposed between the overlapping portion and the pixel structure.
