Optical filter for compensating for color shift and display device having the same

Abstract

An optical filter for compensating for color shift is provided in front of a display panel of a display device. The optical filter includes a background layer and a green wavelength absorption pattern provided with a predetermined thickness on the background layer. The green wavelength absorption pattern absorbs a green wavelength of light. The green wavelength absorption pattern contains a material that absorbs a green wavelength of light in the range of 510 nm to 560 nm, and can also contain a white light absorbing material. A green's complementary color absorbing part absorbs a wavelength of light complementary to green, and contains at least one of a material absorbing a blue wavelength of light in the range of 440 nm to 480 nm and a material absorbing a red wavelength of light in the range of 600 nm to 650 nm. A first thick-film layer, a first thin-film layer, and a second thick-film layer are stacked over one another in the order named.
