Liquid crystal display and fabrication method thereof

A method of fabricating a liquid crystal display, the method comprising:

• depositing a metal film on a substrate and patterning the deposited metal film to form a gate electrode in a transistor region and a storage capacitor lower electrode in a pixel region;
• depositing a gate insulating layer;
• sequentially depositing an intrinsic semiconductor layer and an impurity-doped semiconductor layer on the gate insulating layer and patterning the deposited intrinsic semiconductor layer and impurity-doped semiconductor layer to form an active layer and an ohmic contact layer in the transistor region;
• depositing a metal layer and patterning the deposited metal film to form a source electrode and a drain electrode in the transistor region;
• sequentially depositing an inorganic insulating layer and an organic insulating layer to form a passivation film;
• performing a full exposure to define a contact hole over a drain region of the transistor region and a diffraction exposure over the storage capacitor lower electrode of the pixel region;
• developing and etching to form the contact hole exposing the drain electrode in the transistor region, and etching the passivation film on the storage capacitor lower electrode of the pixel region such that the passivation film has a predetermined thickness;
• and
• depositing a transparent metal film and patterning the deposited transparent metal film to form a pixel electrode functioning as a storage capacitor upper electrode.
