  • Patent number: 8031322
    Abstract: In a method of fabricating a liquid crystal display device, when a photoresist film formed on a substrate for the liquid crystal display device is exposed and developed, protrusions are formed on the substrate for increasing a viewing angle of the liquid crystal display device. Although the substrate is formed with step differences thereon caused by various intermediate films, the protrusions may have a same size since an exposure amount to the photoresist film is varied according to the step differences of the substrate on which the protrusions are formed. Thus, the liquid crystal display device may have an improved display quality.
