Abstract
A method of fabricating an LCD includes providing first and second substrates. A gate electrode, a gate line, a connection electrode, a common electrode and a pixel electrode are formed on the first substrate through a first making process. A first insulation film is formed on the first substrate. A first insulation film pattern having multiple contact holes are formed through a second masking process. An active pattern is formed on the first substrate and source and drain electrodes are operationally connected with the active pattern through some of the contact holes. A gate electrode, a common electrode, and a pixel electrode may be formed substantially together through a slit exposure. An active pattern and source and drain electrodes may be formed substantially together. The number of masks needed to fabricate the display may be reduced to simplify a fabrication process and protect a channel region.
