Abstract
A manufacturing method of a liquid crystal display includes: forming a thin film transistor on a first substrate; forming a color filter on the thin film transistor; forming a pixel electrode on the color filter; and forming a light blocking member including a column spacer protruded from the light blocking member on the color filter. The forming the light blocking member uses a mask including a first region, a second region, and a third region. The first region passes light generated from a light exposer, the second region includes a blocking filter layer which selectively passes the light generated from the light exposer, and the third region blocks the light generated from the light exposer.
