A method for fabricating a liquid crystal display device includes forming a layer of photosensitive material over an entire surface of a first substrate, the first substrate having a first region and a second region defined thereon in which first and second LCD panel models will eventually be formed; aligning a photomask on the layer of the photosensitive material, the photomask including a light shielding material pattered to include first and second transmissive regions having first and second transmissivities, respectively, the second transmissivity being less than the first transmissivity; and selectively exposing the layer of photosensitive material with the photomask; developing the exposed layer of photosensitive material to simultaneously form first and second layers having different thicknesses within the first and second regions, respectively.
