A manufacturing method of a liquid crystal display device includes forming a gate line and a data line on a substrate with the gate and data lines crossing each other to define a pixel region; forming a thin film transistor at a crossing portion of the gate and data lines; forming a passivation layer on the substrate and the thin film transistor; forming a transparent conductive layer on the passivation layer; forming a first photosensitive layer on a portion of the transparent conductive layer over the thin film transistor; forming a second photosensitive layer on the transparent conductive layer and the first photosensitive layer; patterning the second photosensitive layer and the first photosensitive layer to form a photosensitive pattern and a columnar spacer exposing a portion of the transparent conductive layer; forming a pixel electrode by patterning the transparent conductive layer exposed by the photosensitive pattern and the columnar spacer; and removing the photosensitive pattern.
