A method for fabricating a liquid crystal display (LCD) is provided. The method includes the steps stated below. At first, providing an LCD panel including a first substrate, a second substrate and a liquid crystal layer therebetween. The liquid crystal layer includes several photo-sensitive monomers and several liquid crystal molecules. The LCD panel has at least a first pixel and a second pixel. Afterwards, correspondingly driving the first pixel and the second pixel by the first voltage and the second voltage. At last, applying a ultra-violet source onto the LCD panel to enable several photo-sensitive monomers to polymerize several alignment polymers on the first substrate and the second substrate.
