An optical filter for reducing color shift is disposed in front of a display panel of an LCD. The optical filter includes a color shift-reducing layer, which includes a background layer and a plurality of engraved or raised lens sections formed on the background layer such that the lens sections are spaced apart from each other, and an external light-blocking layer. light emitted from the display panel has different colors depending on the viewing angle and the grayscale level, owing to the birefringence characteristics of liquid crystal molecules. The lens sections diffuse a portion of the light incident onto the lens sections, so that the portion of the light is mixed with another portion of the light passing between adjacent lens sections. The external light-blocking layer contains a light-absorbing material, which is a black material that absorbs all wavelengths of visible light. |
