A curved liquid crystal display device includes an upper substrate, a lower substrate, a liquid crystal layer, an upper polarizer film, a lower polarizer film and a plurality of patterned optical compensation films. The upper substrate has a first inner surface and a first outer surface. The lower substrate is disposed opposite to the upper substrate. The lower substrate has a second inner surface and a second outer surface. The liquid crystal layer is sandwiched between the upper substrate and the lower substrate. The upper polarizer film is disposed on the first outer surface, and the lower polarizer film is disposed on the second outer surface. The patterned optical compensation films are disposed locally between the upper polarizer film and the lower polarizer film. Fast axis directions of at least two of the patterned optical compensation films are different from each other.
