An optical filter includes a substrate, a filter layer on the substrate and including color filters, and a light-converting layer over the filter layer and including light-converting portions respectively corresponding to the color filters. A low refractive index layer is between the filter layer and the light-converting layer and has a refractive index less than a refractive index of the light-converting layer. A first capping layer is between the low refractive index layer and the light-converting layer and has a refractive index ranging between the refractive index of the light-converting layer and the refractive index of the low refractive index layer.

A display device includes a first pixel group having first, second, third, and fourth pixels arranged along a column direction, and a second pixel group having fifth, sixth, seventh, and eighth pixels arranged along the column direction. A gate line is connected to the first, second, third, fourth, fifth, sixth, seventh, and eighth pixels. A first data line is connected to the first pixel, the third pixel, the fourth pixel, and the sixth pixel, and a second data line is connected to the second pixel, the fifth pixel, the seventh pixel, and the eighth pixel. The first pixel group and the second pixel group are alternately disposed along a row direction. This arrangement allows inversion driving wherein the first data line receives a voltage having a different polarity from that of the second data line so as to reduce line flickering and reduce power consumption in the display device.
